Description

  The present invention relates to a door opening fixing device.

  Conventionally, as a door opening fixing device, for example, a device described in Patent Document 1 is known. This door opening fixing device is provided in a state in which a lever that is also used as a door inner armrest of a door trim or separately incorporated can swing and can be returned by a spring. And if a lever is rock | fluctuated by hand, the connecting rod connected to this will operate the brake device added to the door check mechanism, and will inhibit opening and closing of a door. In other words, the brake pad is attached to the check link (slide plate) of the door check mechanism, and the movement of the check link, that is, the opening of the door is fixed by pressing against the slide plate with a bar or plate as the lever swings. .

JP 2006-152780 A

  By the way, in Patent Document 1, since the opening degree of the door is fixed by swinging the lever and pressing the brake pad against the slide plate, the force for fixing the opening degree of the door is determined by the input of the operation for swinging the lever. Is done. For this reason, if the input of the operation to swing the lever is small, there is a possibility that the door moves because the force for fixing the opening of the door is insufficient.

  An object of the present invention is to provide a door opening degree fixing device capable of suppressing the influence of the force for fixing the door opening degree from being input when operating to fix the door opening degree.

  A door opening fixing device that solves the above-described problems has a stopper portion, and is rotatably connected to a vehicle body, and is fixed to a vehicle door, and the check link is inserted therethrough. A door check that restricts the door at a fully open position by the stopper part coming into contact with the opening operation, a separation position that opens the movement locus of the stopper part when the door is opened, and a mechanism that blocks the movement locus For opening adjustment, which is provided on the door so as to be movable between joint positions and regulates the door with a half-opening opening degree when the stopper portion comes into contact with the opening operation of the door when the door is in the engaging position. And a latching position for latching the latched portion so as to regulate the closing operation of the door in a state where the door is regulated by the half-opening degree. And the hooked portion A latching member provided on the door so as to be rotatable between a non-latching position for releasing the latch, and linked to the latching member, the latching member being connected to the latching position and the non-latching position. And an operation member that rotates between the two.

  According to this configuration, when the operating member is operated to rotate the hooking member to the hooking position in a state where the door is regulated by the half-opening opening degree, the hooking member is moved to the hooked position. The closing operation of the door is regulated by hooking the latching portion. Thereby, both the opening operation and the closing operation of the door are regulated and fixed at the half-opening degree. In this case, it is sufficient for the input when operating the operation member to fix the opening degree of the door as long as the latch member can be rotated to the latch position. On the other hand, the force for fixing the opening degree of the door is determined by the engaging force with which the hooking member hooks the hooked portion. Therefore, it can suppress that the force which fixes the opening degree of the said door is influenced by the input when operating the said operation member in order to fix the opening degree of the said door.

In the door opening fixing device, it is preferable that the stopper portion is also used as the hooked portion.
According to this configuration, the number of parts can be reduced by using the stopper portion also as the hooked portion.

Regarding the door opening fixing device, it is preferable to do <without citation of claim>.
According to this configuration, if the input when operating the operation member to release the latch member to the latch position is released, the latch member is biased by the bias member. It rotates toward the non-holding position. For this reason, for example, after getting off, by releasing the input when operating the operation member, it is possible to naturally eliminate the closing of the door while the opening degree of the door is fixed.

  The door opening fixing device includes a door trim that forms a lining of the door, the door is supported by the body so as to be freely opened and closed around a rotation center disposed in front of the vehicle, and the operation member is It is preferable that the door trim is disposed above the rear end of the door trim.

  According to this configuration, the operation member is arranged at the upper part of the rear end of the door trim, so that, for example, when getting off the vehicle, the user can easily apply force to the operation member when getting up from the seat.

  INDUSTRIAL APPLICABILITY The present invention has an effect that it is possible to suppress the influence of the force for fixing the door opening on the input when operating to fix the door opening.

The perspective view which shows the structure about one Embodiment of a door opening fixing device. (A), (b) is a side view which shows the structure and operation | movement about the door opening degree fixing device of the embodiment. (A), (b) is a cross-sectional view which shows the structure and operation | movement about the door opening degree fixing device of the embodiment.

  Hereinafter, an embodiment of the door opening fixing device will be described. In the following description, it is assumed that the door is in the closed state, and the direction thereof is made to coincide with each direction of the vehicle (the front-rear direction and the width direction).

  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.

  At the edge portion 2a, at the intermediate portion sandwiched between the door hinges 3, the base end portion of a substantially long check link 11 made of, for example, a metal rod is aligned with the opening / closing direction of the door 4 in the vehicle height direction. It is rotatably connected around an extending axis. On the other hand, 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.

  As shown in FIGS. 2A and 2B, the check link 11 has its longitudinal length with respect to the door check 16 (door 4) while swinging around its base end according to the opening / closing operation of the door 4. Move relative to the direction. For example, when the door 4 is opened, the check link 11 is retracted from the door 4 through the door check 16. On the other hand, when the door 4 is closed, the check link 11 enters the door 4 through the door check 16. 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, as the length of the check link 11 protruding from the door check 16 into the door 4 is longer, the opening degree is smaller. Conversely, as the length is shorter, the opening degree is larger.

  The check link 11 is formed with a plurality of upper and lower trough portions 11a at intervals in the longitudinal direction, and the door check 16 has one of the pair of trough portions 11a sandwiched between the check links 11. A pair of rollers (not shown in the figure) that regulate the movement in the longitudinal direction slightly is incorporated. 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, a stopper portion 12 as a plate-like hooked portion that is wider than the check link 11 in the width direction and the height direction of the vehicle is fixed to the tip end portion of the check link 11. When the check link 11 tries to retract from the door 4 through the door check 16 with the opening operation of the door 4, the stopper portion 12 abuts on the door check 16 to further open the door 4. Regulate operation. The opening degree of the door 4 at this time corresponds to a fully opened opening degree. In other words, the door check 16 regulates the door 4 at the fully open position by the stopper portion 12 coming into contact with the opening operation of the door 4.

  An opening adjustment member 17 made of, for example, a metal plate is connected to the upper end of the door check 16 so as to be rotatable around an axis O1 extending in the vehicle width direction. The opening adjusting member 17 includes a pair of substantially L-shaped side walls 17a that sandwich the check link 11 in the vehicle width direction, and a lid wall 17b that connects the upper edges of both side walls 17a in the vehicle width direction. Have one. The opening adjusting member 17 is provided with a substantially arm-shaped connecting piece 17c extending upward from its upper end. And the front-end | tip surface which opposes the door check 16 of the both-sides wall 17a forms the 1st contact part 18 which contact | abuts so that it may contact | adhere to the door check 16 with the clockwise rotation of illustration around the axis line O1.

  When the first contact portion 18 is in contact with the door check 16, the opening adjustment member 17 interferes with the check link 11 because the lid wall 17 b is positioned above the check link 11. Absent. At this time, the front end surface of the opening adjustment member 17 (both side walls 17a and lid wall 17b) that is separated from the door check 16 forms a second contact portion 19 that faces the stopper portion 12 in the moving direction of the check link 11. To do. Accordingly, when the check link 11 tries to retract from the inside of the door 4 through the door check 16 as the door 4 is opened, the stopper portion 12 abuts on the second abutting portion 19 to further increase the position. The opening operation of the door 4 is restricted. In other words, the opening adjustment member 17 regulates the door 4 with a predetermined half-opening opening degree by the stopper portion 12 coming into contact with the second contact portion 19 as the door 4 is opened.

  The rotation position of the opening adjusting member 17 when the first contact portion 18 contacts the door check 16 and the second contact portion 19 blocks the movement locus of the stopper portion 12 accompanying the opening operation of the door 4. Is called “engagement position”. On the other hand, a predetermined rotation position of the opening adjusting member 17 when the second contact portion 19 opens the movement locus of the stopper portion 12 in accordance with the opening operation of the door 4 is referred to as a “separation position”.

  Further, a latch member 20 made of, for example, a metal plate is rotatably connected to the door check 16 around an axis O2 extending in the vehicle width direction, below the axis O1. The latching member 20 has an arm portion 21 that extends obliquely upward to the right with the axis O2 as the center, and a generally claw-shaped latching portion 22 that protrudes in a clockwise direction from the tip of the arm portion 21 in the figure. Have The latching portion 22 can be brought into contact with the rear end surface 12a of the stopper portion 12 that is in contact with the second contact portion 19 of the opening adjusting member 17 as the shaft O2 rotates. When the latching portion 22 comes into contact with the rear end surface 12a of the stopper portion 12, the backward movement of the stopper portion 12, that is, the closing operation of the door 4 restricted by the half-opening degree is restricted. That is, the latching member 20 is a latching position for latching the stopper portion 12 so as to regulate the closing operation of the door 4 in a state where the door 4 is regulated by the half-opening degree as illustrated by a two-dot chain line in the drawing. As shown by the solid line in the figure, the actuator can be rotated between the non-engaging positions for releasing the latching of the stopper portion 12.

Note that the latching member 20 is biased so as to rotate toward the non-latching position by a return spring 23 as a biasing member wound around the axis O2.
As shown in FIG. 1, a door trim 5 is attached to the door 4. The upper part P of the rear end of the door trim 5 is formed with a substantially rectangular assist grip 5a that is recessed downward, and a switching lever 31 as an operation member is supported corresponding to the assist grip 5a. .

  That is, as shown in FIGS. 3A and 3B, the door 4 is a bag-like structure formed by combining a door outer panel 4a constituting a door outer plate and a door inner panel 4b constituting a door inner plate. In this case, the door window glass DW can appear and disappear from the upward opening. And the door trim 5 is attached to the door inner panel 4b from the vehicle inner side.

  The switching lever 31 is rotatably supported around an axis O3 extending in the front-rear direction (direction perpendicular to the paper surface) at the inner upper end of the assist grip 5a in the vehicle width direction. The switching lever 31 is held at an initial position extending outward in the vehicle width direction along the surface of the door trim 5 by a return spring 32 wound around the axis O3. That is, the switching lever 31 is held at the initial position by which the opening end is closed by the urging force of the return spring 32 so as to cover the assist grip 5a when not in use. When the user puts his / her finger H on the assist grip 5a, the switching lever 31 rotates clockwise from the initial position against the urging force of the return spring 32.

  As shown in FIG. 1, the switching lever 31 is connected to the latching member 20 via the operation cable 33. When the switching lever 31 rotates from the initial position against the urging force of the return spring 32, the switching member 31 pulls the latching member 20 via the operation cable 33 to rotate the latching member 20 toward the latching position. Move. Accordingly, when the user gets off the vehicle, for example, when the user puts his / her finger H on the assist grip 5a and uses it as an assist grip, the switching lever 31 is rotated from the initial position, so that the door is regulated with the half-opening degree as described above. 4 closing operation can be regulated.

  On the other hand, when the switching lever 31 is biased by the return spring 32 and returns to the initial position, the latching member 20 is biased by the return spring 23 and rotates toward the non-latching position. That is, the switching lever 31 rotates the hooking member 20 toward the non-hooking position by returning to the initial position.

  Further, an opening selection lever 6 is rotatably supported on the door 4. The opening selection lever 6 has an opening selection knob 6 a that is exposed to the inside of the vehicle from a substantially arc-shaped long hole 5 b formed in the door trim 5. The opening selection knob 6a is movable to the lower left in the drawing along the long hole 5b as the opening selection lever 6 rotates about the axis. The opening selection lever 6 is connected to a connecting piece 17c of the opening adjusting member 17 through a rod 7 made of, for example, a metal rod. The opening selection lever 6 is pivoted so that the opening selection knob 6a moves obliquely downward to the left along the elongated hole 5b, thereby pulling down the opening adjustment member 17 via the rod 7 and disengaging position. To the engaged position. On the contrary, the opening selection lever 6 pushes up the opening adjustment member 17 via the rod 7 by rotating so that the opening selection knob 6a moves obliquely upward to the right along the elongated hole 5b. To rotate from the engagement position to the disengagement position. That is, the user can select the restriction at the half-opening degree when the door 4 is opened by operating the opening degree selection lever 6.

Next, the effect of this embodiment will be described.
(1) In the present embodiment, when the switching lever 31 is operated to rotate the latching member 20 to the latching position in a state where the door 4 is regulated by the half-opening degree, the latching member 20 is stopped. By closing the portion 12, the closing operation of the door 4 is restricted. Thereby, both the opening operation and the closing operation are regulated and fixed at the half-opening degree of the door 4. In this case, the input when operating the switching lever 31 to fix the opening degree of the door 4 is sufficient if the latching member 20 can be rotated to the latching position. On the other hand, the force for fixing the opening degree of the door 4 is determined by the engaging force with which the latch member 20 latches the stopper portion 12. Therefore, it is possible to suppress the influence of the force for fixing the opening degree of the door 4 from being input when the switching lever 31 is operated to fix the opening degree of the door 4.

It turns toward the non-hanging position. For this reason, for example, after getting off, by releasing the input when operating the switching lever 31, it is possible to automatically eliminate the closing of the door 4 while the opening degree of the door 4 is fixed. Or since the separate operation for canceling | releasing fixation of the opening degree of the door 4 is unnecessary, operativity can be improved more.

  (4) In the present embodiment, the switching lever 31 is disposed at the upper part P of the rear end of the door 4 and is at a relatively high position. For example, when getting off the vehicle, when the user stands up from the seat, It is easy to put in.

  (5) In the present embodiment, the switching lever 31 is disposed on the assist grip 5 a formed on the door trim 5. Therefore, the user naturally touches the assist grip 5a when operating the switching lever 31, and can smoothly get off the vehicle by grabbing the assist grip 5a.

  (6) In this embodiment, the door 4 can be fixed so that both the opening operation and the closing operation are regulated at the half-opening opening degree, so that the user can smoothly support the body while holding the door 4 while holding the door 4. You can get off.

  (7) In this embodiment, since the door check mechanism 10 itself is not changed for fixing the door 4, for example, the influence on the normal operation feeling in the opening / closing operation of the door 4 can be suppressed.

In addition, you may change the said embodiment as follows.
In the embodiment, the opening selection lever 6 that operates the opening adjustment member 17 and the switching lever 31 that operates the latching member 20 are provided independently, but the opening adjustment member 17 and the latching are not provided. A single operation member that operates the member 20 in an interlocked manner may be employed. In this case, for example, after the movement of the opening adjustment member 17 to the engagement position is completed, a timing difference is set in their operation so that the movement of the hook member 20 to the hook position is started. Is preferred.

  In the above-described embodiment, there may be a plurality of half-opening degrees of the door 4 regulated by the opening adjusting member 17. And the latching member 20 may regulate the closing operation | movement of the door 4 regulated by each of the said some half-opening opening degree.

  In the embodiment, the arrangement of the switching lever 31 may be arbitrarily changed as long as the user can apply a force when standing up from the seat. For example, the switching lever 31 may be disposed on the armrest of the door trim 5.

  In the above-described embodiment, the return spring 23 is omitted, and the latch member 20 is rotated from the latch position to the non-engage position by using, for example, an operation force that returns the switching lever 31 to the initial position. It may be.

In the above-described embodiment, the hooked portion that is hooked by the hooking member 20 to restrict the closing operation of the door 4 may be provided separately from the stopper portion 12.
In the embodiment, the latch member 20 and the switching lever 31 are connected via the operation cable 33, but may be connected via a rod, for example.

  In the above embodiment, the opening adjustment member 17 and the opening selection lever 6 are connected via the rod 7, but may be connected via a cable, for example. In this case, an appropriate return spring that rotates the opening adjustment member 17 from the engagement position to the disengagement position may be provided.

In the embodiment, the opening adjustment member 17 may be moved by a linear motion between the disengagement position and the engagement position.
