(First embodiment)
Hereinafter, a first embodiment of the door opening degree adjusting device will be described. Hereinafter, the upper direction and the lower direction in the height direction of the vehicle are referred to as “upper” and “lower”, respectively. Further, the inside in the width direction of the vehicle heading toward the inside of the vehicle interior is referred to as “vehicle inside”, and the outside in the width direction of the vehicle toward the outside of the vehicle interior is referred to as “vehicle outside”. In particular, the width direction of the vehicle with respect to the door (the vehicle inner side, the vehicle outer side) refers to that considered to be closed.

  As shown in FIG. 1, an opening 2 for getting on and off is formed in a side portion of a body 1 of the vehicle, and an edge 2 a in front of the opening 2 is arranged in parallel in the height direction of the vehicle. A door 4 is rotatably connected by a pair of door hinges 3. The door 4 is opened and closed by rotating in one direction and the other direction around the door hinge 3.

  In addition, a base end portion of a substantially long check link 11 made of, for example, a molding material obtained by integrating resin with a metal rod is connected to the edge portion 2a so as to be rotatable in accordance with the opening / closing direction of the door 4. The door 4 is fastened with a door check 16 through which a tip portion of the check link 11 entering the door 4 is movably inserted in the longitudinal direction. The check link 11 and the door check 16 constitute the door check mechanism 10.

  The check link 11 moves relative to the door check 16 (door 4) in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. That is, as shown in FIGS. 2 (a) and 2 (b), the edge 2a is formed with a substantially flat mounting surface 5 that is recessed toward the inside of the vehicle, and the mounting surface 5 is made of, for example, a metal plate. A bracket 12 is fastened. On the other hand, the door 4 has a door outer panel 6 that extends so as to face the outside of the vehicle, and a box-shaped door inner panel 7 that is disposed on the inside of the vehicle. The edge of the door outer panel 6 and the opening of the door inner panel 7 are provided. A substantially sealed internal space is formed by joining the ends. Note that the door 4 is opened and closed by rotating about the shaft 3 a of each door hinge 3.

  The base end portion of the check link 11 is connected to the bracket 12 so as to be rotatable around an axis extending in the vehicle height direction, and the front end portion of the check link 11 is opposed to the rear of the mounting surface 5. It enters the door 4 through the wall portion 8 of the door inner panel 7. On the other hand, the door check 16 is fastened to the wall portion 8 in the door 4, and the tip end portion of the check link 11 entering the door 4 is inserted. As described above, the check link 11 moves relative to the door check 16 in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. Then, as shown by a change from FIG. 2A to FIG. 2B, for example, when the door 4 is opened, the check link 11 is retracted from the door 4 through the door check 16 or the like. Conversely, when the door 4 is closed, the check link 11 enters the door 4 through the door check 16 or the like. That is, the relative position of the check link 11 to the door check 16 uniquely corresponds to the opening / closing position (opening) of the door 4. Specifically, the opening degree decreases as the length L of the check link 11 protruding from the door check 16 into the door 4 increases, and conversely, the opening degree increases as the length L decreases.

  As shown in FIG. 3, the check link 11 has a plurality of upper and lower pairs of valleys 13 and 14 formed at intervals in the longitudinal direction, and the door check 16 has one of the pair of valleys 13 and 14. A pair of rollers (not shown in the figure) are incorporated that slightly restrict the movement of the check link 11 in the longitudinal direction by sandwiching 14. Therefore, when the movement of the check link 11 in the longitudinal direction is slightly restricted by the door check 16, the door 4 is slightly held at the corresponding opening / closing position (opening).

  Further, as shown in FIG. 4, a pair of protruding piece-like stopper portions 15 that extend to both sides in the width direction of the vehicle are formed at the tip of the check link 11. These stopper portions 15 contact the door check 16 when the check link 11 tries to retract from the door 4 through the door check 16 or the like with the opening operation of the door 4, so The opening operation is restricted (see FIG. 2B). The open / close position (opening degree) of the door 4 at this time corresponds to the fully open position.

  A guide member 20 made of, for example, a metal plate is attached to the wall portion 8 of the door 4. The guide member 20 includes a substantially band-shaped mounting wall 21 extending in the height direction of the vehicle, and a pair of support walls extending rearward from both ends (the vehicle outer end and the vehicle inner end) of the mounting wall 21 in the vehicle width direction. 22 and has a substantially U-shape opening rearward. The guide member 20 is fastened (so-called joint fastening) to the wall portion 8 together with the door check 16 in a state where the mounting wall 21 is sandwiched between the wall portion 8 and the door check 16.

  Each support wall 22 is formed with a substantially rectangular guide hole 23 extending in the height direction of the vehicle. In addition, the guide member 20 has a top plate portion 24 that connects the upper edges of the tip portions of the support walls 22. A substantially circular insertion hole 25 that opens in the height direction of the vehicle is formed at the center of the top plate portion 24.

  As shown in FIG. 5, an adjustment member 30 made of, for example, a metal plate is supported on the guide member 20 while being sandwiched between the support walls 22. The adjustment member 30 has a pair of substantially trapezoidal adjustment walls 31 that spread along the inner wall surfaces of both support walls 22. The distance in the vehicle width direction between the two adjustment walls 31 is set to be smaller than the distance between the tips of the stopper portions 15 of the check link 11. The rear end of each adjustment wall 31 forms an inclined portion 32 that inclines toward the front as it goes downward.

  Each adjustment wall 31 is formed with a pair of substantially circular mounting holes 36 and 37 spaced in the height direction of the vehicle. The inner diameters of the mounting holes 36 and 37 are set to be equal to the opening width of the guide hole 23 in the short direction. The adjustment member 30 includes a top plate portion 38 that connects the upper edges of the adjustment walls 31. A substantially circular insertion hole 39 that opens in the height direction of the vehicle is formed at the center of the top plate portion 38.

  The adjustment member 30 is supported by the guide member 20 movably in the vehicle height direction by a pair of guide pins 41 and 42 arranged in parallel in the vehicle height direction on each adjustment wall 31. That is, the guide pins 41 and 42 have substantially disc-shaped head portions 41 a and 42 a having a diameter larger than the opening width in the short direction of the guide hole 23 and are equivalent to the opening width in the short direction of the guide hole 23. And substantially cylindrical insertion portions 41b and 42b protruding from the center of the heads 41a and 42a. The adjustment member 30 is supported by the guide member 20 by inserting and fastening the insertion portions 41b and 42b of the guide pins 41 and 42 inserted through the guide holes 23 from the outside of the support walls 22 into the mounting holes 36 and 37, respectively. Is done. At this time, the adjustment member 30 moves in the height direction of the vehicle with respect to the guide member 20 in a range from a position where the insertion portion 41 b contacts the upper end of the guide hole 23 to a position where the insertion portion 42 b contacts the lower end of the guide hole 23. Is possible.

  The insertion hole 39 of the adjustment member 30 is set so as to be substantially concentric with the insertion hole 25 of the guide member 20 and face the vehicle in the height direction. And between the top plate parts 24 and 38, the compression spring 43 which consists of coil springs, for example is interposed. Both ends of the compression spring 43 are in pressure contact with the peripheral portions of the insertion holes 25 and 39, respectively, and always urge the adjustment member 30 downward against the guide member 20.

  The lower end 45 of the cable 44 that basically extends in the height direction of the vehicle is sequentially inserted into the insertion holes 25 and 39 together with the compression spring 43. The terminal 45 is secured to the top plate portion 38 below the insertion hole 39. The terminal on the upper side of the cable 44 is connected to an adjustment dial 46 exposed in the passenger compartment (for example, on the door trim), and the vehicle between the top plate portion 24 and the terminal 45 is operated by turning the adjustment dial 46. The distance in the height direction is configured to be extendable. In other words, the adjustment member 30 urged downward by the compression spring 43 reduces the distance between the top plate portion 24 and the terminal 45 with respect to the guide member 20 as the adjustment dial 46 rotates in one direction. As the distance between the top plate portion 24 and the terminal 45 extends as the adjustment dial 46 rotates in the reverse direction, the adjustment dial 46 descends with respect to the guide member 20. At this time, the movement of the adjusting member 30 is guided by sliding the guide pins 41 and 42 in the respective guide holes 23. The adjustment dial 46 only needs to be equipped with a known mechanism that winds and unwinds the cable 44 in accordance with, for example, the turning operation.

Next, each stopper part 15 and the inclined part 32 of each adjustment wall 31 will be described.
As shown in an enlarged view in FIG. 6A, each stopper portion 15 has a plurality of check side step portions 15 a in the moving direction of the check link 11. The front end surface of the stopper portion 15 is raised stepwise by these check-side step portions 15a so as to go forward (in the moving direction of the check link 11) as it goes downward. Each check-side step 15a is raised by a predetermined length with respect to the adjacent check-side step 15a, and the vehicle height dimensions of all the check-side steps 15a are set to be equal to each other.

  On the other hand, the inclined portion 32 of each adjustment wall 31 has a plurality of adjustment-side step portions 32 a in the moving direction of the check link 11. The adjustment side step portion 32a has a higher number of steps than the check side step portion 15a. The inclined portion 32 is raised stepwise by these adjustment-side step portions 32a so as to go backward (in the moving direction of the check link 11) as it goes upward. Each adjustment-side step portion 32a is raised by the predetermined length with respect to the adjacent adjustment-side step portion 32a, and the vehicle height dimension of all the adjustment-side step portions 32a is the vehicle of the check-side step portion 15a. It is set to be the same as the dimension in the height direction. In other words, the plurality of adjustment-side step portions 32a are adjusted by adjusting the position of the inclined portion 32 (adjustment member 30) in the vehicle height direction, as shown by a two-dot chain line in FIG. It can come into contact with the check-side step portion 15a of the step in a fitted state.

  In particular, as further enlarged and shown in FIG. 6B, each adjustment-side step 32a is formed with a substantially arc-shaped chamfer 33 as a guide at the protruding corner. Therefore, when the check link 11 is moved forward so that the plurality of check-side step portions 15a are fitted to the adjustment-side step portion 32a, the corner portions of the check-side step portion 15a and the corner portions of the adjustment-side step portion 32a are Even if they are abutted, the check-side step portion 15a and the adjustment-side step portion 32a are smoothly fitted by guiding the corner portion of the check-side step portion 15a to the chamfer 33. .

Next, the operation of this embodiment will be described.
First, as shown in FIG. 7 (a), the position of the adjustment member 30 is adjusted to the lowest position of the movable range by rotating the adjustment dial 46, and the check link 11 is inclined on the forward movement locus. It is assumed that the upper end portion of the portion 32 is arranged. In this state, the opening operation of the door 4 is restricted when each stopper portion 15 of the check link 11 retracted from the door 4 comes into contact with the upper end portion of the inclined portion 32. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L1, and the opening operation of the door 4 is restricted by the first opening.

  In addition, as shown in FIG. 7B, the position of the adjustment member 30 is adjusted by the turning operation of the adjustment dial 46, and the lower end of the inclined portion 32 is arranged on the forward movement trajectory of the check link 11. To do. In this state, the opening operation of the door 4 is restricted by the stopper portions 15 of the check link 11 retracting from the inside of the door 4 coming into contact with the lower end of the inclined portion 32. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L2 (<L1), and the opening operation of the door 4 is performed at a second opening larger than the first opening. Be regulated.

  In both the above-described positions where the adjustment member 30 restricts the opening operation of the door 4, the stopper portion 15 and the inclined portion 32 are set so that the check-side step portion 15a and the adjustment-side step portion 32a abut in a fitted state. Has been. That is, the upward movement distance of the adjustment member 30 indicated by the change from FIG. 7A to FIG. 7B is the vehicle height direction of each check-side step portion 15a (or adjustment-side step portion 32a). It is an integral multiple of the dimensions. Further, even if the adjustment member 30 is at an arbitrary position from FIG. 7A to FIG. 7B, for example, the upward movement distance of the adjustment member 30 from the state shown in FIG. If the side step portion 15a (or the adjustment side step portion 32a) is an integral multiple of the vehicle height dimension, the door 4 is similarly opened when the check side step portion 15a and the adjustment side step portion 32a are fitted. Is regulated. In other words, the turning operation of the adjustment dial 46 related to the adjustment of the position of the adjustment member 30 may have a sense of moderation so that it can be adjusted to the height direction dimension of the vehicle, such as each check side step portion 15a. preferable.

  If the position of the adjustment member 30 is adjusted by rotating the adjustment dial 46 and the adjustment member 30 is arranged above the door check 16, the opening operation of the door 4 is retracted from the door 4 accordingly. The stoppers 15 of the check link 11 are regulated by contacting the door check 16. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 becomes zero, and the opening operation of the door 4 is restricted at the fully open position.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In this embodiment, the opening operation accompanying the rotation of the door 4 in one direction is such that the plurality of check-side step portions 15a of each stopper portion 15 are adjusted by the plurality of adjustment-side step portions 32a of the adjustment member 30. It is regulated by coming into contact with either one in a fitted state. Then, the maximum opening degree of the door 4 is obtained by moving the adjustment member 30 and changing the plurality of adjustment-side step portions 32a with which the plurality of check-side step portions 15a of the stopper portions 15 abut in the fitted state. Can be adjusted. In this case, the adjustment member 30 can more firmly restrict the opening of the door beyond the adjusted opening degree by the contact of each stopper portion 15. In particular, the plurality of check-side step portions 15a of each stopper portion 15 and the plurality of adjustment-side step portions 32a of the adjustment member 30 are brought into contact with each other in a fitted state, thereby significantly reducing the dimensions of the step portions 15a and 32a. Even if it does, the influence which it has on the regulation of the door 4 can be suppressed. Therefore, the opening degree of the door 4 can be adjusted more precisely.

  (2) In this embodiment, the chamfer 33 guides the contact of the check-side step portion 15a and the adjustment-side step portion 32a in the fitted state, whereby the door 4 can be more reliably regulated. it can.

  (3) In the present embodiment, the adjustment member 30 can sandwich the check link 11 in the vehicle width direction (a parallel direction different from the movement direction of the check link 11 and the movement direction of the adjustment member 30). A pair of adjustment walls 31 provided with a plurality of adjustment side step portions 32a is provided. Further, the check link 11 has a pair of stopper portions 15 so as to be able to come into contact with both adjustment walls 31. Accordingly, the opening operation associated with the rotation of the door 4 in one direction is such that both stopper portions 15 (a plurality of check-side step portions 15a) of the check link 11 are both adjusted walls 31 (a plurality of adjustment-side step portions 32a). It is regulated by abutting on each. Therefore, it is possible to more firmly regulate the opening of the door 4 beyond the adjusted opening. In this case, the check link 11 can further stabilize the posture of the check link 11 by the stopper portions 15 coming into contact with both the adjustment walls 31 that sandwich the check link 11 in the vehicle width direction.
