Description

  The present invention relates to a check link device that defines a fully open position of a door of a vehicle.

  Conventionally, a check link device is known as a device that is disposed between a vehicle body and a door and defines a fully open position (maximum open position) of the door.

  For example, in Patent Document 1, after bending the main body of the arm downward and further upward, the first contact portion and the second contact portion extending in the vertical direction are formed, and the arm is inserted. A door check device provided with stopper means for restricting the fully open position of the door by bringing the first and second contact portions into contact with the case is disclosed.

Japanese Patent No. 4005227

  The check link device as described above is provided at one end of the arm due to assembly tolerance when installed in the vehicle, a stopping posture when the vehicle stops on a flat road or a slope, and further due to deterioration over time. The stopper portion may come into contact with the holding member that receives the stopper portion. One-sided contact is a phenomenon in which, for example, the contact surface of the stopper portion and the holding member are in contact with each other in a state of being out of parallel with each other, and it is difficult to completely suppress the occurrence.

  Here, in the case of the door check device of Patent Document 1, when the first abutting portion of the stopper means hits the case and receives a load, the arm portion directly contacts the bent portion of the arm portion. There is a possibility that a load is applied, the bent portion of the first contact portion is deformed and pushed back, and does not function as the stopper means. Further, the second contact portion is formed by extending the arm portion downward and then extending upward, and has a shape extending long above the arm portion. Therefore, the second contact portion of the stopper means is the case. However, if the load comes into contact with each other, the base portion of the second contact portion is deformed and pushed back, and may not function as the stopper means. Furthermore, there is a concern that the vertical dimension of the stopper means increases and the apparatus becomes larger.

  The present invention has been made in consideration of the above-described problems of the prior art, and even if the stopper portion of the arm and the holding member are in contact with each other, the check link device can prevent the function of the stopper portion from being impaired. The purpose is to provide.

  The check link device according to the present invention is provided with a plate-like arm portion, a stopper portion provided at one end of the arm portion, and provided at the other end of the arm portion, and is rotatably connected to one of the vehicle body and the door. A holding member that is attached to the other of the vehicle main body or the door, is slidably inserted through the arm portion, and defines a fully open position of the door by contact with the stopper portion A check link device, wherein the stopper portion extends from the arm portion to one end side and is inclined to one side in the plate thickness direction of the arm portion, and from the step portion. An extension portion further extending to one end side, and a first contact that contacts the holding member by being arranged on the extension portion and extending to the other side in the plate thickness direction of the arm portion. And having a part That.

  According to such a configuration, the step portion inclined to one side in the plate thickness direction of the arm portion is formed to extend from the arm portion to one end side, and the load when the door is opened is brought into contact with the holding member. Since the contact portion to be received is formed as the first contact portion so as to extend to the other side in the thickness direction of the arm portion, when the stopper portion receives a load regardless of the load direction due to one piece, the arm portion Since there is no contact portion formed by bending on the opposite side of the first contact portion with respect to the longitudinal direction of the first contact portion, the contact portion is deformed to the other end side, and between the holding member of the stopper portion. The position control function of the door is not affected, and the function as the stopper portion can be maintained. In addition, since the base portion of the first contact portion with respect to the extending portion is located on the step side with respect to the other side surface in the thickness direction of the arm portion, the arm portion is pulled in the longitudinal direction. Due to the load generated when the stopper portion comes into contact with the holding member, deformation of the base portion is effectively suppressed, and the function of the first contact portion as a stopper is not impaired.

  The first contact part is formed by bending from the extension part to the other side in the plate thickness direction of the arm part, and a bent part from the extension part to the first contact part is the It is good also as a structure provided in the position which cross | intersects the extension line of the said other side surface in the plate | board thickness direction of an arm part, or the position which becomes the said step part side rather than the said extension line. Then, since the bent part of the first contact part is located on the step part side with respect to the other side surface of the arm part, deformation of the bent part is effectively suppressed, and the first contact part is suppressed. It can prevent that the function as a stopper of a part is impaired.

  The extension part has a forward part further extended from the step part to one end side, and a return part extended from one end of the forward part to the other end side of the arm part by a folding part. The bent portion may be provided in the return portion. Thereby, when the stopper portion receives a load regardless of the load direction due to the one-piece contact, the folded portion can be deformed, and therefore, the deformation of the bent portion of the first contact portion is suppressed, and the first portion It is possible to prevent the standing posture of the contact portion from being destroyed.

  The stopper portion has a close contact portion in which a flat surface of the forward portion and a flat surface of the return portion are in close contact, and the close contact portion is provided at a position included in a range of the plate thickness of the arm portion. It may be. In this way, the spread direction that occurs between the forward part and the return part when receiving the opening and closing load of the door by bringing the flat part of the forward part integrally extending from the arm part into close contact with the flat part of the return part Therefore, it is possible to prevent the folded portion from being deformed excessively, and to maintain the function of the stopper portion for a long period of time.

  The forward portion may be provided with a second contact portion that is formed wider than the arm portion and whose plate thickness portion can contact the holding member. Thereby, since the second contact portion receives a load on its plate thickness surface, deformation due to the load is unlikely to occur, and the load direction at the time of contact with the holding member with which the first contact portion abuts is Since the first contact portion is not one direction acting on the bent portion or the folded portion by the first contact portion, the other direction orthogonal to this one direction is affected, so that the load received by the second contact portion affects the first contact portion. This is suppressed, and the first contact portion is not deformed.

  The first contact portion and the second contact portion may have the same position in the longitudinal direction of the arm portion. If it does so, the load which a 1st contact part and a 2nd contact part receive can be equalized more.

  When the forward portion and the return portion are formed so as to be substantially parallel to the arm portion, the dimension of the arm portion of the stopper portion in the plate thickness direction can be reduced, and the apparatus can be configured compactly. .

  When the stopper portion is covered with a resin material, it is possible to suppress the generation of an impact sound when contacting the holding member. At this time, in the check link device, since the deformation of the first contact portion is suppressed as described above, it is possible to prevent the resin material from peeling off at the stopper portion when receiving a load. As a result, the durability of the stopper portion can be improved.

  According to the present invention, the step portion inclined to one side in the plate thickness direction of the arm portion is formed to extend from the arm portion to one end side, and receives a load when the door is opened at the time of contact with the holding member. By forming the contact portion as the first contact portion to extend to the other side in the thickness direction of the arm portion, when the stopper portion receives a load regardless of the load direction due to the one-piece contact, the length of the arm portion Since there is no contact part formed by bending on the opposite side of the first contact part with respect to the direction, this contact part is deformed to the other end part side, and the door between the holding member of the stopper part The function as a stopper portion can be maintained without affecting the position regulating function. In addition, since the base portion of the first contact portion with respect to the extending portion is located on the step side with respect to the other side surface in the thickness direction of the arm portion, the arm portion is pulled in the longitudinal direction. Due to the load generated when the stopper portion comes into contact with the holding member, deformation of the base portion is effectively suppressed, and the function of the first contact portion as a stopper is not impaired.

  Hereinafter, preferred embodiments of a check link device according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a side sectional view of a check link device 1 according to an embodiment of the present invention. FIG. 2 is a plan view conceptually showing a main part of a four-wheeled vehicle on which the check link device 1 is mounted, and FIG. 2 (A) is a plan view with the door D closed, B) is a plan view with the door D opened.

  As shown in FIGS. 1 and 2, the check link device 1 includes a holding member 10 and an arm 20, and is disposed between a vehicle body (vehicle body) B and a door D. In this embodiment, the front seat right door of the vehicle main body B is illustrated as the door D to which the check link device 1 is applied. The door D is rotatably supported at the front end by the door hinge Hj of the vehicle body B, and the door D is opened from the closed state shown in FIG. 2 (A) with the door hinge Hj as the rotation center. It can be opened and closed.

  The holding member 10 is inserted in a state in which the arm 20 is slidable along the longitudinal direction (see also FIG. 6), and the door D is fully opened by contact with a stopper portion 20 c provided at one end of the arm 20, which will be described later. It defines the position (maximum open position).

  In the case of this embodiment, the holding member 10 includes a case 11 and a cover plate 12, and holds the check mechanism 14 in a box-shaped space formed by the case 11 and the cover plate 12. The case 11 and the cover plate 12 are made of, for example, a steel plate. The cover plate 12 is locked and fixed to the case 11 by a locking claw 11 b formed on the case 11, and the holding member 10 is fixed to the door panel DP by attaching the case 11 to the door panel DP by two bolts 13. Has been.

  The opening 10 a of the holding member 10 through which the arm 20 is inserted is formed by openings 11 a and 12 a formed at the center of the case 11 and the cover plate 12. Of course, the holding member 10 may have a structure other than the structure using the case 11 and the cover plate 12, and may be, for example, an integrally structured box.

  The check mechanism 14 includes a pair of sliding bodies 15, 15 that are in contact with both upper and lower surfaces of the arm 20, and a pair of coil springs 16, 16 that urge each sliding body 15 toward the arm 20. Each sliding body 15 is formed of a synthetic resin having a small friction coefficient with respect to the coating 22 of the arm 20, for example, polyacetal. Instead of the coil spring 16, an elastic body such as rubber may be used.

  FIG. 3 is a plan view of the arm 20 of the check link device 1, and FIG. 4 is an enlarged perspective view of the stopper portion 20c of the arm 20 and its peripheral portion. 5 is an enlarged view of the stopper portion 20c of the arm 20 and its peripheral portion, FIG. 5 (A) is a plan view, FIG. 5 (B) is a side view, FIG. 5 (C) is a bottom view, and FIG. D) is a front view.

  As shown in FIGS. 1 and 3 to 5, the arm 20 is composed of a plate-shaped cored bar 21 and a synthetic resin coating 22 covering the cored bar 21, and slightly along the longitudinal direction in plan view. It is a plate-like member having a curved shape. The arm 20 is provided with a plate-like and long arm portion 20a, a connecting portion 20b formed at one end of the arm portion 20a, and a stopper portion 20c formed at the other end of the arm portion 20a. The material of the coating 22 is preferably a synthetic resin that is easy to process and has high strength. For example, thermoplastic resins such as polypropylene, nylon, ABS resin, and polyacetal are suitable. In FIGS. 4 and 5, the coating 22 is indicated by a two-dot chain line in order to clearly show the shape of the cored bar 21.

  As shown in FIGS. 1 and 3, the connecting portion 20 b is provided with a connecting hole 20 e at the center so that an opening 21 e described later is not exposed by the coating 22. As shown in FIGS. 1, 4, and 5, the stopper portion 20 c is a flat contact surface Fc on the arm portion 20 a side that contacts the holding member 10 (cover plate 12).

  As shown in FIG. 1, the arm 20 is connected to a bracket Bk fixed to the vehicle body B by a swing pin P at one end of the connecting portion 20 b and inserted through an arm insertion hole Ha formed in the door panel DP. A stopper portion 20 c at the other end of the portion 20 a is disposed in the door D via the holding member 10.

As shown in FIG. 1, the arm 20 is molded with a coating 22 so that the thickness of the synthetic resin covering the cored bar 21 changes along the longitudinal direction. That is, the covering 22 has a constant thickness on the side of the connecting portion 20b of the arm portion 20a, but after gradually increasing toward the center, the intermediate thickness decreases (first checking portion P _C1 ), and then increases. Thus, the thickness is constant, and the thickness is again reduced in the vicinity of the stopper portion 20c (second check portion _PC2 ).

  As shown in FIGS. 1 and 3 to 5, a cored bar 21 constituting the arm 20 includes an arm core part (arm part) 21 a made of a steel plate slightly curved along the longitudinal direction, and an arm core part 21 a. A connecting core portion (connecting portion) 21b formed at one end and a stopper core portion (stopper portion) 21c formed at the other end of the arm core portion 21a and extending in the width direction and the plate thickness direction of the arm core portion 21a. It is formed into a T-shape.

  Resin holes 21d are formed at appropriate portions of the arm core portion 21a. Since the resin of the coating 22 enters the resin hole 21d, the arm core portion 21a and the coating 22 are difficult to peel off. An opening 21e having a slightly larger diameter than the connection hole 20e is formed in the connection core portion 21a at a position corresponding to the connection hole 20e at one end.

  Here, the structure of the stopper portion 20c will be described more specifically with reference mainly to FIG. 4 and FIG.

  The stopper portion 20c is formed by molding the stopper core portion 21c of the core metal 21 into a rectangular taper shape that tapers toward the tip with a cover 22, and the end surface of the cover 22 on the arm portion 20a side is in contact with the holding member 10. A contact surface Fc is formed.

  As shown in FIGS. 4 and 5, the stopper core portion 21c extends from the arm core portion 21a to one end side, and toward one side (downward in this embodiment) in the plate thickness direction of the arm core portion 21a. The inclined step portion 23a, the forward portion 23b further extended from the step portion 23a to one end side so as to be substantially parallel to the arm core portion 21a, and the arm core portion 21a from one end of the forward portion 23b. The return part 23d is folded back and extended toward the end side and is substantially parallel to the arm core part 21a, and the other side in the plate thickness direction of the arm core part 21a (opposite to the step part 23a side). A first contact portion 23e bent from the return portion 23d to the side (upper side in this embodiment). In other words, the stopper portion 20c (stopper core portion 21c) has an extending portion 24 formed by extending the forward portion 23b, the folded portion 23c, and the returning portion 23d from the step portion 23a. 1 contact part 23e is arranged upright.

  The step portion 23a is an inclined portion in which one end of the arm core portion 21a is extended obliquely downward from the longitudinal direction (see FIG. 5B). The step portion 23a extends while inclining to a position where the upper surface thereof coincides with or substantially coincides with the plate thickness center line O of the arm core portion 21a in a side view of FIG. 5B.

  The forward portion 23b extends from the tip of the step portion 23a so as to be substantially parallel to the arm core portion 21a, and the upper surface thereof substantially coincides with the plate thickness center line O (see FIG. 5B). The forward portion 23b is formed wider than the arm core portion 21a and the stepped portion 23a (see FIG. 5C), and has a tapered trapezoidal shape when viewed from the bottom of FIG. 5C. 2 contact portion 23f is formed (see also FIG. 5B).

  The return portion 23d is folded back in the opposite direction from the forward portion 23b by the turned-back portion 23c, and extends in the direction of the connecting core portion 21b so as to be substantially parallel to the arm core portion 21a, and the lower surface thereof is the plate thickness center line. It is almost the same as O. The lower surface of the return portion 23d and the upper surface of the forward portion 23b are in close contact with each other to form a close contact portion 23g. The return portion 23d is formed wider than the arm core portion 21a and the step portion 23a in the same manner as the forward portion 23b, and has a trapezoidal shape that becomes wider toward the first contact portion 23e in the plan view of FIG. It is.

  The folded portion 23c that folds between the forward portion 23b and the return portion 23d is joined by the welded portion W between the top surface of the forward portion 23b that protrudes outward from the return portion 23d and the end surface of the return portion 23d. It is formed (see FIGS. 5A, 5B, and 5D). The folded portion 23c may be formed by folding a single plate instead of joining by welding (for example, see FIG. 8).

  The first contact portion 23e is a wall-like portion whose root portion is bent and extended upward from the return portion 23d by the bent portion 23h so as to be substantially orthogonal to the surface of the arm core portion 21a. The side surface on the portion 21b side is located above the step portion 23a (see FIGS. 5A to 5D). The first contact part 23e and the bent part 23h are formed wider than the arm core part 21a and the step part 23a, like the forward part 23b and the reverse part 23d. When the door D is opened to the fully open position, the first contact portion 23e contacts the upper edge portion of the opening 10a of the holding member 10 through the covering 22 and receives the load when the door D is opened. (See FIGS. 5A and 5B).

  The bent portion 23h is provided at a position in contact with the extension line L of the surface on the first contact portion 23e side (upper surface in the present embodiment) in the thickness direction of the arm core portion 21a. That is, the extension line L passes through the curved surface forming the bent portion 23h. Note that the bent portion 23h may be shifted to the step portion 23a side (lower side in the present embodiment) from the extension line L when the downward inclination of the step portion 23a is set large, for example. In this case, the extension line L passes through the first contact portion 23e. Accordingly, as is apparent from FIG. 5B, the close contact portion 23g between the forward portion 23b and the return portion 23d is also located below the extension line L (on the opposite side to the stance direction of the first contact portion 23e). It will be. In other words, in the stopper core portion 21c, the contact portion 23g is disposed within the range of the plate thickness of the arm core portion 21a (between the extension line L and the extension line on the lower surface) (see FIG. 5B). ). Of course, when the downward inclination of the step portion 23a is set to be large, the close contact portion 23g coincides with the extension line on the lower surface of the arm core portion 21a or is positioned below the extension line.

  The second abutting portion 23f is formed by a plate thickness portion of the portion extending in the width direction from the step portion 23a of the forward portion 23b, and is a position offset with respect to the holding member 10 rearward from the first abutting portion 23e. (See FIGS. 5B and 5C). When the door D is opened to the fully open position, the second contact portion 23f is a portion for contacting the left and right edges of the opening 10a of the holding member 10 through the cover 22 and receiving the load (see FIG. 5 (C)).

  FIG. 6 is a plan view showing the positional relationship between the holding member 10 and the arm 20 of the check link device 1 when the door D is opened and closed. A reference symbol Ch in FIG. 6 indicates the center of the door hinge Hj of the vehicle main body B.

  First, like the arm 20 indicated by a solid line in FIGS. 1 and 6, when the door D is closed with respect to the vehicle main body B, the check link device 1 has a pair of sliding members in the holding member 10 fixed to the door D. With the moving body 15 in sliding contact with the upper and lower surfaces of the arm 20, the position closest to the swing pin P, that is, the stopper portion 20 c is disposed at the position farthest from the holding member 10. At this time, the arm 20 is disposed along the front-rear direction of the vehicle main body B.

  Next, when the door D is opened with respect to the vehicle main body B from the state shown by the solid line in FIG. 6, the check link device 1 moves the arm 20 around the axis of the swing pin P as the door D opens. In FIG. 6, it is rotated counterclockwise, and the holding member 10 moves along the arm 20 toward the stopper portion 20 c as the arm 20 rotates. During this time, the pair of sliding bodies 15 slide along the upper and lower surfaces of the arm 20 by the spring force of the pair of coil springs 16 and move along the arm 20, while the pair of coil springs 16 correspond to the shape of the upper and lower surfaces of the arm 20. Is moved up and down while appropriately elastically deforming.

By moving along this arm 20, the holding member 10, reaches the first check unit P _C1 of the arm 20, the recess shape of the spring force and the coating 22 of a pair of coil springs 16, a pair of sliding body 15 is first The movement from one check unit _PC1 is restricted. As a result, the arm 20 is stopped at the intermediate open position Pm shown in FIG. The opening angle of the door D relative to the center Ch of the door hinge Hj at this time is shown by reference numeral theta ₁ in FIG.

When the door D is further opened from the state of the opening angle θ ₁ , the holding member 10 reaches the second check part _PC 2 of the arm 20. Accordingly, in the check link device 1, the cover plate 12 of the holding member 10 contacts the stopper portion 20 c of the arm 20. In this state, the movement of the pair of sliding bodies 15 from the second check portion _{PC2 in} the longitudinal direction of the arm 20 is restricted by the spring force of the pair of coil springs 16 and the hollow shape of the covering 22. As a result, the arm 20 is stopped at the fully open position Pfo shown in FIG. 6 which is opened with respect to the vehicle main body B together with the door D from the intermediate open position Pm. The opening angle of the door D with respect to the center Ch of the door hinge Hj at this time is indicated by reference sign θ ₂ in FIG.

  In such a fully open position Pfo, since the cover plate 12 of the holding member 10 and the contact surface Fc of the stopper portion 20c of the arm 20 are in contact with each other, the check link device 1 has a door D with respect to the vehicle main body B. Can be prevented from being further opened, and the door D can be held at the fully open position Pfo with respect to the vehicle body B.

On the other hand, when the door D is closed from the fully opened position Pfo described above, the holding member 10 fixed to the door D moves the arm 20 around the axis of the swinging pin P via the pair of sliding bodies 15 in the clockwise direction in FIG. The holding member 10 moves to the bracket Bk side along the arm 20 while being rotated. During this time, the pair of sliding bodies 15 slide along the upper and lower surfaces of the arm 20 by the spring force of the pair of coil springs 16 and move along the arm 20, and the pair of coil springs 16 according to the shape of the upper and lower surfaces of the arm 20. Is moved up and down with respect to the arm 20 while being elastically deformed. Due to the movement along the arm 20, the holding member 10 is operated in the reverse direction to the case of opening the door D, and the position closest to the swing pin P side from the second check part _PC2 through the first check part _PC1. Move to.

  Incidentally, in the check link device 1, the holding member 10 may come into contact with the stopper portion 20 c of the arm 20 when the door D is opened or closed due to deterioration over time due to repeated use. As described above, in the case of the door check device disclosed in Patent Document 1, when the first abutting portion of the stopper means comes into contact with the case and receives a load, it is directly applied to the bending portion of the arm portion with the main body. There is a possibility that a load is applied, the bent portion of the first contact portion is deformed and pushed back, and does not function as the stopper means.

  On the other hand, in the stopper part 20c of the check link device 1 according to the present embodiment, the step part 23a and the forward part 23b are provided on the stopper core part 21c of the cored bar 21 that substantially receives the load when the door D is opened and closed. And an extending portion 24 including a return portion 23d and a first abutting portion 23e.

  In this way, the step portion 23a inclined to one side in the thickness direction of the arm core portion 21a is formed to extend from the arm core portion 21a to one end side, and further, the door D is opened when contacting the holding member 10. The first contact portion 23e that receives the load at the time is formed to extend only to the other side (the upper side in FIG. 5B) in the thickness direction of the arm core portion 21a, so that the load direction due to one-side contact Regardless of whether the stopper 20c receives a load regardless of the longitudinal direction of the arm core 21a, the stopper 20c is bent on the opposite side of the first contact portion 23e (the lower side in FIG. 5B). Since there is no contact portion (a contact portion corresponding to the second contact portion of Patent Document 1), the contact portion is deformed to the other end side (the tip side of the stopper portion 20c), and the holding member for the stopper portion 20c. The position restriction function of the door D with the door 10 is not affected, and the stopper It is possible to maintain the function as 20c.

  In addition, the base portion (folded portion 23h) of the first contact portion 23e with respect to the extending portion 24 is lower than the surface on the other side (first contact portion 23e side) in the plate thickness direction of the arm core portion 21a. Since the arm core portion 21a is attracted in the longitudinal direction and the stopper portion 20c contacts the holding member 10, the first contact portion 23e is located on the (step portion 23a side). It is possible to effectively suppress deformation of the base portion of the first and second portions, and the function of the first contact portion 23e as a stopper is not impaired.

  In the stopper portion 20c, the bent portion 23h from the return portion 23d to the first contact portion 23e is the other side surface in the plate thickness direction of the arm core portion 21a (arm portion 20a) (upper surface in FIG. 5B). Since it is provided at a position that contacts (intersects) the extended line L, or at a position closer to the step 23a side (lower side in FIG. 5B) than the extended line L, deformation of the bent part 23h is prevented. can do.

  In the present embodiment, the configuration in which the coating 22 is molded as the stopper portion 20c is illustrated, but the configuration may be such that the stopper core portion 21c is exposed without molding the coating 22 on the stopper portion 20c. The stopper core portion 21c functions as the stopper portion 20c as it is, and the first contact portion 23e and the second contact portion 23f function as the contact surface Fc with the holding member 10, and the following modifications Is the same.

  In the present embodiment, the extending part 24 extends further from one end of the forward part 23b to the other end side of the arm core part 21a by the forward part 23b further extended from the step part 23a to the one end side and the folded part 23c. The bent portion 23h is provided in the return portion 23d. Accordingly, when the stopper portion 23c receives a load regardless of the load direction due to the one-side contact, the folded portion 23c can be deformed, and therefore the deformation of the bent portion 23h of the first contact portion 23e is suppressed. The standing posture of the first contact portion 23e can be prevented from being broken. Further, the stopper core portion 21c constituting the stopper portion 20c has one plane of the forward portion 23b (upper surface in FIG. 5B) and one plane of the return portion 23d (lower surface in FIG. 5B) closely attached. The contact portion 23g is provided, and the contact portion 23g is provided at a position included in the range of the plate thickness of the arm core portion 21a (arm portion 20a). In this way, by bringing the flat surface of the forward portion 23b integrally extending from the arm core portion 21a and the flat surface of the return portion 23d into close contact, the forward portion 23b and the return portion when receiving the opening / closing load of the door D. Since the deformation in the spreading direction that occurs during 23d can be reduced, the folded portion 23c can be prevented from being excessively deformed while preventing the folded portion 23h from being deformed, and the function of the stopper portion 20c can be extended over a long period of time. Can be maintained.

  At this time, since the forward portion 23b and the return portion 23d are both formed so as to be substantially parallel to the arm core portion 21a, the dimension in the plate thickness direction of the arm core portion 21a of the stopper portion 20c is reduced, and the device Can be configured compactly.

  The close contact portion 23g is provided at a position that coincides with or substantially coincides with an extension line at the center of the thickness of the arm core portion 21a (arm portion 20a), that is, the thickness center line O (see FIG. 5B). . That is, the contact portion 23g of the forward portion 23b and the return portion 23d of the stopper core portion 21c folded back by the folded portion 23c substantially coincides with the direction of the thickness center of the arm core portion 21a (arm portion 20a). Therefore, when the stopper portion 20c receives a load, a force is applied to the stopper core portion 21c substantially evenly in the folding direction (vertical direction in FIG. 5B) at the folding portion 23c, and local deformation occurs. Therefore, it is possible to increase the strength of the stopper portion 20c against the load from the door D.

  In the check link device 1, the forward portion 23 b of the stopper core portion 21 c (stopper portion 20 c) is formed wider than the arm core portion 21 a (arm portion 20 a), and the plate thickness portion can contact the holding member 10. A second contact portion 23f is provided. Since the second contact portion 23f receives a load on its plate thickness surface, it is less likely to be deformed by the load. Moreover, the second contact portion 23f is not the upper edge portion of the opening 10a of the holding member 10 with which the first contact portion 23e contacts, or the left and right edge portions of the opening 10a, not the lower edge portion opposite to the upper edge portion. The direction of contact with the holding member 10, that is, the direction of the load at the time of contact with the holding member 10, is one direction in which the first contact portion 23e acts on the bent portion 23h and the folded portion 23c (vertical direction in FIG. However, since it is in the other direction orthogonal to this one direction, the load received by the second contact portion 23f is suppressed from affecting the first contact portion 23e, and the first contact portion 23e is deformed. It does not occur.

  In the above description, the second contact portion 23f is exemplified as having a position that is offset rearward from the first contact portion 23e with respect to the holding member 10 (see FIGS. 5B and 5C). As shown in FIGS. 7A and 7B, the second contact in which the position of the arm core portion 21a (arm portion 20a) in the longitudinal direction is aligned with the first contact portion 23e. You may comprise as the contact part 23i. If it does so, the load which the 1st contact part 23e and the 2nd contact part 23i receive can be equalized more.

  The stopper core portion 21c may be configured as a stopper core portion (stopper portion) 21f in which the second contact portion 23f (23i) is omitted, as shown in FIG. In the stopper core portion 21f, a single plate having the same width is formed from the arm core portion 21a to the step portion 23a, the forward portion 23b, the folded portion 23c, the return portion 23d, the bent portion 23h, and the first contact portion 23e. Configured. Such a stopper core part 21f has an advantage that it can be made smaller than the stopper core part 21c. In FIG. 8, illustration of the coating 22 is omitted. Of course, the coating 22 may not be provided on the stopper core 21f. Moreover, although the example which comprised the folding | turning part 23c by folding forming of a plate-shaped member is shown in FIG. 8, it is good also as a structure joined by the welding part W as mentioned above.

  In the check link device 1, the stopper core portion 21c (21f) is covered with the covering 22 in the stopper portion 20c. Thereby, it is possible to suppress the generation of an impact sound when contacting the holding member 10. At this time, in the check link device 1, since the deformation of the first contact portion 23e is suppressed as described above, the coating 22 is prevented from being peeled off from the stopper core portion 21c when receiving a load. As a result, the durability of the stopper portion 20c can be improved.

  In the above description, the first contact portion 23e is formed by bending the return portion 23d from the forward portion 23b by the return portion 23c and the bent portion 23h (see FIG. 5). As shown in FIG. 9B, the first contact portion 27b may be joined and erected on the upper surface of the extended portion 27a extended from the step portion 23a. That is, as shown in FIGS. 9A and 9B, the stopper core portion 26 according to this modified example has a step portion 23a so as to be substantially parallel to the step portion 23a and the arm core portion 21a. An extended portion 27a further extended from the one end to the one end side, and a base portion is formed by a welded portion W on the upper surface of the extended portion 27a (the surface opposite to the step portion 23a in the plate thickness direction of the arm core portion 21a). It has the 1st contact part 27b fixed and standing, and the 2nd contact part 27f. Note that the second contact portion 23i shown in FIG. 7 may also be applied to the stopper core portion 26, and all the plate widths may be the same as the plate width of the arm core portion 21a.

  In such a stopper core portion 26 as well, the first contact portion 27b that receives the load when the door D is opened at the time of contact with the holding member 10 is used as the plate of the arm core portion 21a. By extending and installing only in the thickness direction on the other side (the upper side in FIG. 9B), the side opposite to the first contact portion 27b (FIG. 9 (FIG. 9 (B)) with respect to the longitudinal direction of the arm core portion 21a. In B), there is no bent contact portion (the contact portion corresponding to the second contact portion in Patent Document 1) on the lower side, so this contact portion is on the other end side (the stopper portion 20c). The function as the stopper portion 20c can be maintained without affecting the position regulating function of the door D between the stopper member 20c and the holding member 10 of the stopper portion 20c. Further, the base portion of the first contact portion 27b with respect to the extending portion 27a is lower (on the step portion 23a side) than the surface on the other side (first contact portion 27b side) in the plate thickness direction of the arm core portion 21a. Therefore, the deformation of the base portion of the first contact portion 27b is effectively suppressed, and the function of the first contact portion 27b as a stopper is not impaired. In addition, the stopper core portion 26 has a simple structure in which the first contact portion 27b is fixed to the upper surface of the extending portion 27a, and thus has an advantage that the manufacturing cost is low.

  As shown in FIGS. 10A to 10D, the stopper core portion 21c extends while the second contact portion 23f is curved in a circular arc shape downward. You may comprise as the stopper core part 30 comprised as follows. The second contact portion 28 is formed on an end surface of an arcuate arc portion 29 that is curved inward while extending downward from both side surfaces of the forward portion 23b. By providing the arc portion 29 as described above, the coating 22 can be more firmly fixed (molded) to the stopper core portion 30, and the rigidity of the stopper portion 20 c is increased. The impact at the time of contact can be received more reliably. Of course, the arc portion 29 having the second contact portion 28 may be applied to the stopper core portion 21c shown in FIGS. 5 and 7 and the stopper core portion 21f shown in FIG.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, in the above description, a configuration in which the holding member 10 is attached to the door D and the connecting portion 20b is rotatably supported by the bracket Bk provided on the vehicle main body B is illustrated. It is good also as a structure which provided in the vehicle main body B and supported the connection part 20b on the door D so that rotation was possible.

  Further, in the above, the check link device 1 in which the first contact portion 23e is disposed above is illustrated, but the direction of the arm 20 can be appropriately changed depending on the vehicle type on which the check link device 1 is mounted, Needless to say, the one abutting portion 23e may be used in a downward direction, a horizontal horizontal direction, or an inclined posture.
