  In the door checker for automobiles disclosed in Patent Document 1, a pair of shoes having protrusions that can be engaged with the notches of the check lever plate and are opposed to each other with the check lever plate interposed therebetween, and these shoes are pressed against the check lever plate. Since the detent mechanism is configured by housing the elastic member that urges and urges in a case, the number of parts of the detent mechanism is large, and there is a limit in reducing the cost. In addition, the case is configured as a box type with a cover plate because it accommodates the shoe and the elastic member, and a fully open stopper provided at the free end of the check lever plate is brought into contact with the outer end surface of the box type case. Since the door fully open position is regulated, the check lever plate sliding stroke corresponding to the door opening and closing stroke corresponds to the distance from the outer edge of the case to the check lever plate full opening stopper when the door is fully closed. , The length of the portion of the check lever plate that penetrates the case is not included in the sliding stroke of the check lever plate, and the entire length of the check lever plate increases accordingly. For this reason, when the door is fully closed, it may be difficult to avoid interference with the door window glass at the free end of the check lever plate.

  The present invention has been made in view of such circumstances, and has made it possible to reduce the number of parts of the detent mechanism and to reduce the overall length while ensuring a predetermined sliding stroke of the check lever plate. An object of the present invention is to provide the automobile door checker having a simple structure and compactness.

  In order to achieve the above object, a check lever plate that is pivotally connected to a body of an automobile and has a detent notch on an opposing slide surface, and is fixed to a door pivotally supported on the body, the check lever plate A door checker for an automobile, comprising: a case penetrating in a relatively movable manner; and a detent mechanism provided in the case for holding the door in a predetermined open position in cooperation with the detent notch. Is formed in a U-shaped cross section so as to include a base plate portion fixed to the door and a pair of side plate portions connected to both ends of the base plate portion, while the detent mechanism is sandwiched by the check lever plate. A detent plate having a pair of plate members opposed to each other, each plate member having a protrusion engaged with the corresponding detent notch And a pair of leaf spring portions integrally connected to both ends of the detent plate portion, and the detent plate portion is attached to the leaf spring portion while supporting the pair of leaf spring portions of each plate member. A pair of support holes are provided in the pair of side plate portions to exert a resilient force urging toward the check lever plate side, and a fully open stopper provided in the free end portion of the check lever plate is brought into contact with the base plate portion. The first feature is that the fully open position of the door is regulated.

  In addition to the first feature of the present invention, the ends of the pair of leaf springs of each of the plate members are bent in opposite directions and engaged with the edges of the corresponding support holes, A second feature is that a locking claw for preventing the movement of the plate member is formed.

  Furthermore, in addition to the first or second feature, the third feature of the present invention is that the protrusion is formed on the detent plate portion so as to protrude in a rib shape extending in the longitudinal direction of the detent plate portion.

  Furthermore, in addition to any one of the first to third features, the present invention provides both sides of the check lever plate at the opening edge of the through hole of the base plate portion through which the check lever plate slidably passes. A fourth feature is that a hemming bent portion that slidably guides the surface is formed, and the fully open stopper is brought into contact with the hemming bent portion to restrict the fully open position of the door.

  According to the first aspect of the present invention, the detent mechanism includes a detent plate portion having a protrusion that engages with a detent notch of the check lever plate, and a detent plate portion that is supported by the case and biases the detent plate portion toward the check lever plate. Since it is composed of two parts, ie, a pair of upper and lower plate members having a pair of leaf springs that exerts a resilient force, the number of parts is extremely small, and the cost can be effectively reduced. Moreover, desired rigidity and elasticity can be freely imparted to the plate member by selecting the plate thickness, and various required characteristics of the door checker can be met.

  In addition, the fully open stopper provided at the free end of the check lever plate is brought into contact with the base plate of the case to regulate the fully open position of the door, so that the check lever plate slides corresponding to the door opening / closing stroke. The stroke corresponds to the distance from the base plate of the case to the fully open stopper of the check lever plate when the door is fully closed, and the length of the part of the check lever plate that passes through the case is also the sliding stroke of the check lever plate. Accordingly, the entire length of the check lever plate can be shortened, and the door checker can be made compact, and the material cost of the check lever plate can be reduced.

  According to the second feature of the present invention, the ends of the pair of leaf springs of each plate member are bent in opposite directions and engaged with the corresponding edge portions of the support holes. Since the locking claw for preventing the movement is formed, the plate member can be held in the case without using a special holding member.

  According to the third feature of the present invention, since the protrusion is formed on the detent plate portion so as to protrude in a rib shape extending in the longitudinal direction of the detent plate portion, the rigidity of the detent plate portion is enhanced by the rib effect of the protrusion, and the leaf spring It is possible to effectively exert the detent effect on the protrusion by effectively acting the elastic force of the portion on the protrusion.

  According to the fourth aspect of the present invention, a hemming bent portion that slidably guides both side surfaces of the check lever plate is provided at the opening edge of the through hole of the base plate portion through which the check lever plate slidably passes. In this way, the fully open stopper is brought into contact with this hemming bent portion to restrict the fully open position of the door. Therefore, the opening edge of the through hole of the base plate portion is reinforced by the hemming bent portion, and the check lever plate In addition to guiding the movement smoothly, the base plate part can sufficiently withstand the contact impact of the fully open stopper of the check lever plate.

The fully open stopper 17 is brought into contact with the hemming bent portion 18 to restrict the fully open position of the door D.

  Next, the operation of this embodiment will be described.

  In assembling the door checker C, first, the pair of left and right pairs of the case 1 and the upper and lower pairs of support holes 16, 16; 16, 16 are respectively provided with the leaf spring portions 14, 14; Inserted and attached, the protrusions 13a and 13a of the detent plate portions 13 and 13 are made to face each other. At that time, the leaf spring portions 14, 14; 14, 14 are respectively subjected to compressive deformation in the support holes 16, 16; 16, 16, and the repulsive force causes the locking claws of the left and right leaf spring portions 14, 14 to be engaged. 15 and 15 are engaged with the locking portions 16 a and 16 a of the support holes 16 and 16, so that the leaf spring portions 14 and 14 are prevented from dropping from the support holes 16 and 16.

  Next, the check lever plate 5 is inserted between the upper and lower detent plate portions 13 and 13 from the side plate portions 1b and 1b side of the case 1 with the base end portion having the pivot hole 6 at the head. At that time, the upper and lower detent plate portions 13 and 13 are pressed in the direction away from each other by the check lever plate 5, and compressive deformation is applied to the corresponding U-shaped plate spring portions 14 and 14, and the repulsive force The protrusions 13 a and 13 a of both detent plate portions 13 and 13 are in pressure contact with the corresponding slide surface 10 of the check lever plate 5.

  The base end portion of the check lever plate 5 inserted between the upper and lower detent plate portions 13, 13 is inserted into the through hole 4 of the base plate portion 1 a, and then the pivot hole 6 of the base end portion via the pivot shaft 8. Attach the bracket 7. In this way, the door checker assembly is assembled.

  After that, in the automobile assembly factory, the base plate portion 1a of the case 1 is fixed to the inner surface of the front end wall of the door D with the bolt 2, and the bracket 7 is fixed to the body B with the bolt 9.

  Thus, when the door D is opened from the fully closed position, the case 1 moves to the free end side of the check lever plate 5 and at the same time, the check lever plate 5 rotates about the pivot shaft 8. Then, according to the above movement of the case 1, the left and right side surfaces of the check lever plate 5 are guided by the hemming bent portion 18 of the base plate portion 1a of the case 1 and slide, and the protrusions 13a of the upper and lower detent plate portions 13, 13 When 13a slides on the slide surfaces 10 and 10 of the check lever plate 5 and the door D reaches a predetermined half-open position, the protrusions 13a and 13a are moved to the check lever by the resilient force of the plate spring portions 14 and 14, respectively. By dropping into the half-open detent notches 10a and 10a of the plate 5, the opening torque of the door D increases rapidly, whereby the door D can be held at a predetermined half-open position.

  Further, when a further opening force is applied to the door D to cause the protrusions 13a and 13a of the detent plate portions 13 and 13 to escape from the half-open detent notches 10a and 10a, and the door D reaches a predetermined fully open position, this time the detent plate portion The protrusions 13a, 13a of the 13, 13 fall into the fully open detent notches 10b, 10b, and at the same time, the fully open stopper 17 of the check lever plate 5 comes into contact with the hemming bent portion 18 of the base plate portion 1a of the case 1, thereby Is restricted to the fully open position.

Since it is composed of two parts of a pair of upper and lower plate members 12, 12 having a pair of leaf spring portions 14, 14 that exert a resilient force to urge the detent plate portion 13 toward the check lever plate 5 side, The number of parts is extremely small, and cost can be reduced effectively. In addition, the plate members 12 and 12 can be freely given desired rigidity and elasticity by selecting the plate thickness, and can cope with various required characteristics of the door checker.

  Further, since the fully open stopper 17 provided at the free end portion of the check lever plate 5 is brought into contact with the base plate portion 1a to restrict the fully open position of the door D, the check lever plate 5 corresponding to the opening / closing stroke of the door D is selected. The sliding stroke corresponds to the distance from the base plate portion 1a of the case 1 to the fully open stopper 17 of the check lever plate 5 when the door D is fully closed, and the length of the portion of the check lever plate 5 passing through the case. In addition, it is included in the sliding stroke of the check lever plate 5, and the entire length of the check lever plate 5 can be shortened accordingly. As a result, the door checker C can be made compact so that the free end of the check lever plate 5 can easily avoid interference with the door window glass when the door D is fully closed. The material cost of the plate 5 can be reduced.

  Further, in each plate member 12, the ends of the pair of plate spring portions 14, 14 are bent in opposite directions and engaged with the edge portions of the corresponding support holes 16 of the case 1 to move the plate member 12. Therefore, the plate member 12 can be held in the case 1 without using a special holding member.

  Further, the detent plate portion 13 is formed with protrusions 13a engaging with the half-open and full-open detent notches 10a and 10b so as to protrude in a rib shape extending in the longitudinal direction of the detent plate portion 13. 13 can be increased, and the elastic force of the leaf spring portions 14 and 14 can be effectively applied to the protrusion 13a to effectively exert the detent effect on the protrusion 13a.

  Further, a hemming bent portion 18 that slidably guides both side surfaces of the check lever plate 5 is formed at the opening edge of the through hole 4 of the base plate portion 1a through which the check lever plate 5 passes slidably. Since the fully open stopper 17 is brought into contact with the hemming bent portion 18 to restrict the fully open position of the door D, the opening edge portion of the through hole 4 of the base plate portion 1a is reinforced by the hemming bent portion 18 to check the lever. The movement of the plate 5 is smoothly guided, and the base plate portion 1a can sufficiently withstand the contact impact of the fully open stopper 17 of the check lever plate 5.

  Next, a second embodiment of the present invention shown in FIG. 5 will be described.
