DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 3 is a perspective view showing the vehicle door holding device according to the present embodiment. As shown in the figure, an opening portion 2 for getting on and off is formed in a side portion of a vehicle body 1 as a first member, and a pair of upper and lower sides is formed on an edge portion 2a on the vehicle front side of the opening portion 2. Around the door hinge 3, a vehicle door 4 as a second member is rotatably supported. The vehicle door 4 opens and closes by rotating around the door hinge 3 to one side and the other side.

  In addition, a base end portion of the long check lever 11 is rotatably connected to the edge portion 2a in accordance with the opening / closing direction of the vehicle door 4, and the vehicle door 4 (inner panel) is connected to the edge portion 2a. A known D / C (door check) case 12 is fastened through which the tip of the check lever 11 is movably penetrated in the longitudinal direction. The check lever 11 moves relative to the D / C case 12 (vehicle door 4) in the longitudinal direction while swinging around its base end according to the opening / closing operation of the vehicle door 4.

  The check lever 11 is formed with a plurality of upper and lower valleys (not shown) spaced in the longitudinal direction, and the D / C case 12 has any one of the pair of valleys. A pair of rollers (not shown) are incorporated that slightly restrict the movement of the check lever 11 in the longitudinal direction by being sandwiched. Therefore, in a state where the movement of the check lever 11 in the longitudinal direction is slightly restricted by the D / C case 12, the vehicle door 4 is slightly held at the opening / closing position corresponding to the vehicle body 1. The check lever 11 and the D / C case 12 constitute a door check mechanism 10.

  Further, a base end portion of a round bar-shaped check arm 21 made of, for example, a metal material is rotatably connected to the edge portion 2a in accordance with the opening / closing direction of the vehicle door 4 below the door check mechanism 10. At the same time, a guide bracket 22 made of, for example, a metal plate is fastened to the vehicle door 4 (inner panel) so that the distal end portion of the check arm 21 is movably penetrated in the longitudinal direction. The check arm 21 moves relative to the guide bracket 22 (vehicle door 4) in the longitudinal direction while swinging about the base end portion according to the opening / closing operation of the vehicle door 4. That is, the guide bracket 22 supports the tip end portion of the check arm 21 so as to be able to advance and retreat so as to allow the check arm 21 to move in the longitudinal direction. The check arm 21 and the guide bracket 22 constitute a door check mechanism 20.

  Next, the door check mechanism 20 will be further described. FIG. 1 is a perspective view showing the door check mechanism 20. As shown in the figure, a U-shaped bracket 23 made of a metal plate is attached to the edge portion 2a by fastening, and a proximal end of an intermediate bracket 24 is attached to a distal end portion of the bracket 23. The base end portion 21a of the check arm 21 is rotatably connected in such a manner that the portion is rotatably connected, and further sandwiched by a bifurcated portion on the distal end side that bisects the intermediate bracket 24 vertically. As a result, the base end portion 21 a of the check arm 21 is allowed to rotate in accordance with the opening / closing direction of the vehicle door 4.

  On the other hand, the guide bracket 22 includes a first bracket 25 and a second bracket 26 made of metal plates that are juxtaposed in the longitudinal direction of the vehicle door 4 along the longitudinal direction of the check arm 21 and fastened together. The first bracket 25 has a pair of support walls 25a and 25b which are spaced apart from each other in the longitudinal direction of the check arm 21 and extend on a plane perpendicular to the center line of the check arm 21, and these support walls 25a and 25b. A connection wall 25c is provided to bridge between the upper ends of the walls 25a and 25b. The support walls 25a and 25b allow the check arm 21 to be moved in the longitudinal direction when the check arm 21 is inserted therethrough.

Is protruding. On the other hand, a constraining member made of a torsion coil spring and a coil spring 29 as an elastic member are disposed between the support walls 25a and 25b. In the coil spring 29, the check arm 21 is inserted into a spiral coil portion 29a as a contact portion, and one end (fixed end) is locked to the first bracket 25 (support wall 25b). The other end 29 b as a free end of the coil spring 29 is locked to the locking pin 28. That is, the entire circumference of the check arm 21 is surrounded by the coil portion 29 a between both ends (fixed end and free end) of the coil spring 29.

  The coil portion 29a of the coil spring 29 reduces or prevents twisting in the circumferential direction when the lever 27 is at an initial position (shown by a solid line) which is a predetermined rotation position on the counterclockwise rotation side in FIG. It is released and the diameter is expanded. At this time, the coil portion 29a allows the check arm 21 to move in the axial direction.

  On the other hand, the coil portion 29a of the coil spring 29 is maximum in the circumferential direction when the lever 27 is at a tightening limit position (shown by a two-dot chain line) which is a predetermined rotation position in the clockwise direction in FIG. The diameter is reduced by twisting to the limit. At this time, the check arm 21 (periphery) is tightened toward the radially inner side of the coil portion 29a by the coil portion 29a. And the frictional force between the said check arms 21 which press-contacts to this coil part 29a is increased by the increase in the fastening force by the coil part 29a. That is, the lever 27 moves the other end (free end) 29b so as to increase the frictional force between the coil portion 29a and the check arm 21. Thereby, the movement of the check arm 21 in the axial direction is restricted, and the vehicle door 4 is held at an arbitrary opening / closing position with respect to the vehicle body 1.

  A hook-shaped locking piece 27a is formed at the tip of the lever 27 that extends away from the check arm 21. The first bracket 25 has a connecting wall 25d that bridges the lower ends of the support walls 25a and 25b below the locking piece 27a. The locking piece 27a includes a connecting wall 25d. A terminal of an internal wire (not shown) that can be projected and retracted from the terminal of the locked outer tube 30 is locked. This internal wire is connected to an operating lever 6 (see FIG. 3) as lever driving means provided so as to be exposed at the vehicle door 4 and is pushed and pulled according to the operation of the operating lever 6. The operation lever 6 is engaged with the vehicle door 4 (inner panel or the like) so as to be selectively held at a release position where the lever 27 is placed at the initial position or a restraining position where the lever 27 is placed at the tightening limit position. Yes. Or you may make it selectively switch and hold | maintain the operation lever 6 to a cancellation | release position or a restraint position, for example using a moderation spring etc.

  The lever 27 is rotated to the tightening limit position against the urging force of the coil spring 29 by transmitting the operating force through the internal wire. At this time, when the operating force is transmitted through the lever 27, the coil spring 29 tightens the check arm 21 against the urging force of the coil portion 29a and restrains the movement of the check arm 21. On the other hand, the lever 27 is biased by the coil spring 29 when the operating force through the internal wire is released, and returns to the initial position. At this time, the coil spring 29 elastically returns the coil portion 29 a so as to release the restrained state of the movement of the check arm 21 with the release of the operating force via the lever 27.

  As shown in FIG. 1, the second bracket 26 is formed with a guide wall 26a projecting in a trapezoidal shape on the check arm 21 side adjacent to the support wall 25b.

These guide rollers 31 are arranged such that a plane including their rotation axes is orthogonal to the center line of the check arm 21, and are in sliding contact with the outer peripheral surface on the check arm 21 side.

  The second bracket 26 includes a support wall 26b extending parallel to the longitudinal direction of the check arm 21 on one side in the radial direction of the check arm 21 (upper left side in FIG. 1) continuously from the tip of the guide wall 26a. Are formed, and a pair of L-shaped extending walls 26c and 26d are formed at the upper and lower ends of the support wall 26b. The center line of the check arm 21 passes through the C-shaped central portion formed by the support wall 26b and the extension walls 26c and 26d.

  A support bracket 32 made of, for example, a metal plate is fixed to the support wall 26b, and a similar support bracket 33 is fixed to a tip portion of the extension walls 26c and 26d that faces the support wall 26b. . A pair of guide rollers 34 are rotatably connected to the support brackets 32 and 33 (only one guide roller 34 is shown in FIG. 1). These guide rollers 34 are juxtaposed on both the left and right sides in the radial direction of the check arm 21. These guide rollers 34 are arranged such that a plane including their rotation axes is orthogonal to the center line of the check arm 21, and are in sliding contact with the outer peripheral surface on the check arm 21 side.

  That is, the check arm 21 is positioned in the vertical direction by the guide roller 31 and is positioned in the horizontal direction by the guide roller 34 to guide its movement in the longitudinal direction. Thereby, the front-end | tip part 21b of the check arm 21 is supported by the guide bracket 22 (vehicle door 4) so that advance / retreat is possible.
