Description

  The present invention relates to a double door structure.

  Patent Document 1 below discloses a seal structure in a double door that can be freely opened and closed. Specifically, a sealing property is ensured by embedding a magnet in a seal member provided at the tip of each door.

JP 2000-146419 A

  However, there is room for improvement in terms of sealing performance in the above technique. On the other hand, there is a structure in which the sealing performance is improved in the double door, but the door opening / closing order is limited.

  In view of the above facts, an object of the present invention is to provide a double door structure capable of improving the sealing performance without limiting the opening and closing order.

  The double door structure according to the first aspect of the present invention includes a pair of door main bodies that are pivotably supported at the base end sides of the doors, and provided inside the doors at the respective distal end portions of the pair of door main bodies. Each of the pair of rubber seal members and the pair of door main bodies is provided on each of the pair of door main bodies, and each of the pair of seal members can be contacted from the inner side of the door by sliding from the initial position to the door tip side. A pair of sliding members, a first sliding means for sliding a sliding member of a door body that is closed first among the pair of door main bodies toward the distal end side of the door, and a sliding of the door body that is closed behind among the pair of door main bodies. Second sliding means for sliding the member toward the door proximal end side.

  In this double door structure, each of the pair of door main bodies is pivotably supported at the base end side and can be double open. And the sealing member is provided in the door inner side of the front-end | tip part of a pair of door main body, respectively.

  Here, the double door structure includes first sliding means. A 1st slide means slides the sliding member of the door main body closed previously among a pair of door main bodies to the said door front end side. For this reason, when any one of the pair of door main bodies is closed, the sliding member of the door main body slides toward the front end side of the door. The slide member thus slidable can come into contact with both of the pair of seal members. Therefore, in a state where both doors are closed, water and the like are prevented from entering the inside of the vehicle by contacting both the slide member of the door body closed first and the pair of seal members.

  Further, the double door structure includes second sliding means. The second sliding means slides the sliding member of the door main body, which is closed later, of the pair of door main bodies to the door proximal end side. For this reason, it is not hindered to close the door by the sliding member of the door body to be closed later, and both doors can be closed without any trouble.

  As can be seen from the above description, in this double door structure, both doors can be closed without any trouble, even if both doors are closed first, and both doors are closed. The sealing performance is ensured. In particular, since the seal member can be pressed against the slide member, sufficient sealing performance can be exhibited.

  According to a second aspect of the present invention, in the double door structure according to the first aspect of the present invention, the first slide means is formed on each of the pair of slide members, from the door inner side direction to the door base end side. The first inclined surface of the door body that is configured to include a first inclined surface that faces the inclined direction and a pair of fixing pins, and the fixing pin on the door body side that closes first among the pair of fixing pins first closes. By abutting against the inclined surface, the slide member of the door body that is closed first slides to the front end side of the door, and the second slide means is formed on each of the pair of slide members, and from the door inner side direction to the front end side of the door. A second inclined surface of the sliding member of the door body, which is configured to include a second inclined surface facing the inclined direction and the distal ends of the pair of sliding members, and the distal end of the sliding member of the door body closed earlier is closed later In By contacting the slide member of the door body to close later slides the door proximally.

  In this double door structure, the first sliding means and the second sliding means can be realized with a simple mechanical structure.

  A double door structure according to a third aspect of the present invention is the double door structure according to the second aspect, further comprising a pair of springs for applying an elastic force toward the initial position to the pair of slide members, Is set at a position where the slide member on one side does not interfere with the door body on the other side, and the length in the door inside / outside direction from the slide member to the tip of the door body is the inside / outside of the door of the first inclined surface. It is set longer than the length of the direction.

  By the way, in a state in which both door bodies are closed, the slide member on the side closed first slides from the initial position to the front end side of the door. For this reason, when trying to open the door body closed earlier from this state, there is a possibility that the above-mentioned sliding slide member interferes with the front end of the door body closed later and the door cannot be opened.

  Here, the double door structure includes a pair of springs that apply an elastic force toward the initial position to the pair of slide members. The initial position is set to a position where the slide member on one side does not interfere with the tip of the door body on the other side. For this reason, when the previously closed door body is opened, the sliding member tries to return to the initial position where it does not interfere with the door body due to the elastic force of the spring.

  Further, in this double door structure, the length in the door inside / outside direction from the slide member to the tip of the door body is set longer than the length of the first inclined surface in the door inside / outside direction. For this reason, before the slide member interferes with the front end portion of the door body, the fixing pin is detached from the first inclined surface and the slide member returns to the initial position, so that the door opening operation can be performed without any trouble.

  As described above, the double door structure according to the present invention has an excellent effect that the sealing performance can be improved without restricting the opening and closing order.

  Hereinafter, an embodiment of a double door structure according to the present invention will be described with reference to FIGS. FIG. 8 shows a double door 10 provided at the rear of the vehicle to which the double door structure of the present embodiment is applied. The double door 10 includes a right door 12 on the right side when viewed from the rear of the vehicle (as viewed from the outside of the vehicle) and a left door 14 on the left side when viewed from the rear of the vehicle. Is rotatably supported by the hinge 16.

  In the following description, in each door of the right door 12 and the left door 14, the rotation center side is referred to as a door base end side, and the direction opposite to the door base end side is referred to as a door front end side. The arrow (base end) in this figure indicates the door base end side, and the arrow (tip end) indicates the door front end side.

  Also, in the direction perpendicular to the surface formed by each door, the direction in which the door moves when the door is closed (the direction inside the vehicle when the door is closed) is called the inside of the door, and the door is opened when the door is opened. The direction in which the vehicle moves (the direction that becomes the vehicle outside when the door is closed) is called the door outside. The arrow (inside) in this figure indicates the inside of the door, and the arrow (outside) indicates the outside of the door.

  FIG. 1 is a sectional view showing the structure near the tip of the right door 12. As shown in this figure, the right door 12 has a door outer panel 18 that constitutes the outside of the door, and a door inner panel 20 that constitutes the inside of the door. The door outer panel 18 is bent inward at the end portion on the door front end side, and hemmed to the end portion on the door front end side of the door inner panel 20. The door inner panel 20 includes a vertical wall portion 20A extending in the door inner direction from the end portion on the door front end side, and a general portion 20B constituting a surface facing the door inner side. The door outer panel 18 and the door inner panel 20 are examples of the “door body” of the present invention.

  A seal rubber 22 formed of an elastic material (rubber) is provided on the inner surface of the door outer panel 18 on the inner side of the door (the front end 18A, which corresponds to the “front end of the door body” of the present invention). Installed. The seal rubber 22 is an example of the “seal member” in the present invention.

  An opening is formed in the vertical wall portion 20A of the door inner panel 20, and a guide 24 for guiding a sliding direction of a slide plate 26 described later is disposed in the opening. The guide 24 is formed in a substantially rectangular parallelepiped box shape with the door front end open, and includes a bottom 24A formed at the door proximal end of the guide 24, a door outer end of the bottom 24A, and a door inner side. And a pair of side portions 24B extending from the direction end portion to the door front end side.

  Inside the guide 24 (a portion surrounded by the pair of side portions 24B), a slide plate 26 (a part thereof) is disposed. The slide plate 26 is slidable along the side 24 </ b> B of the guide 24 to the door front end side and the door base end side. The slide plate 26 is an example of the “slide member” in the present invention.

  The bottom 24A of the guide 24 and the slide plate 26 are connected by a spring 28. When the right door 12 is opened by the elastic force of the spring 28, the slide plate 26 of the right door 12 is arranged at the initial position shown in FIG. This initial position is such that when the right door 12 is closed while the slide plate 26 is placed at the initial position, the end (front end 30) of the slide plate 26 on the front end side of the door is on the center line C of the door opening. It is set to ride. A plurality of springs 28 are provided at intervals in the vehicle vertical direction. Further, as shown in this figure, the front end portion 18A of the door outer panel 18 does not reach the center line C.

  The slide plate 26 has an outer surface 32 facing the door outer direction. On the outer surface 32, the slide plate 26 comes into contact with the seal rubber 22. At this time, the positional relationship between the two (the slide plate 26 and the seal rubber 22) is set so that the seal rubber 22 is slightly compressed inward and outward of the door. That is, the seal rubber 22 of the right door 12 and the slide plate 26 of the right door 12 are brought into contact with each other with a certain level of seal pressure. The outer surface 32 is also a surface that contacts the side portion 24B (outside of the door) of the guide 24.

  Further, the slide plate 26 is provided continuously from the first inclined surface 34 facing the direction slightly inclined from the door inner side to the door base end side, and the door front end side of the first inclined surface 34, and the door is opened from the door inner direction. And a second inclined surface 36 facing in a direction slightly inclined toward the distal end side. The second inclined surface 36 is formed on the door distal end side of the slide plate 26, and the first inclined surface 34 is formed on the door proximal end side of the slide plate 26.

  In addition, since the left door 14 has the same configuration (left-right symmetry) as the right door 12 described above, description thereof is omitted.

  As shown in FIG. 8, a fixing pin 38 is provided on the vehicle body side where the right door 12 and the left door 14 are supported via a hinge 16. A total of four fixing pins 38 are provided on the upper and lower sides in the vehicle vertical direction, one pair on the left and right. Hereinafter, the fixing pin 38 provided on the right side as viewed from the rear of the vehicle may be referred to as the right fixing pin 38R, and the fixing pin 38 provided on the left side may be referred to as the left fixing pin 38L.

  FIG. 2 shows the fixing pin 38 in an enlarged manner. The arrow RR shown in this figure indicates the rear of the vehicle, the arrow UP indicates the upper side of the vehicle, the arrow RH indicates the right side in the vehicle width direction, and the arrow LH indicates the left side in the vehicle width direction. The fixing pins 38 are provided so as to bridge the base plate 44 fixed to the vehicle body side panel 40 with screws 42, a pair of foot portions 46 standing from the base plate 44 toward the rear of the vehicle, and the pair of foot portions 46. The contact portion 48 is formed. The contact portion 48 has a cylindrical shape whose longitudinal direction is the vehicle vertical direction, and comes into contact with the slide plate 26 when each door is closed or slightly opened.

  The position of the right fixing pin 38R in the vehicle width direction is such that when the opened right door 12 is closed, the first inclined surface 34 of the slide plate 26 at the initial position (see FIG. 1) is in contact with the right fixing pin 38R. The position is set so as to contact the portion 48 (initial contact point P1). Further, the position of the left fixing pin 38L in the vehicle width direction is set to a position symmetrical to the right fixing pin 38R across the center line C of the door opening.

  The cross-sectional structures of the right door 12 and the left door 14 of the present embodiment are shown in FIG. 1 in substantially the entire range (the range excluding the upper end and the lower end) in the door vertical direction (the vertical direction of the paper surface of FIG. 1). The structure is substantially the same as the cross-sectional structure. However, the present invention is not limited to this. For example, the first inclined surface 34 is formed only in a portion corresponding to the contact portion 48 of the fixing pin 38 in the vehicle vertical direction, and the first inclined surface 34 is formed in the other portions. It may not be formed.

  Next, the operation of the double door 10 will be described.

  First, an operation when the right door 12 is closed from a state where both the right door 12 and the left door 14 are opened will be described. In the opened right door 12, the slide plate 26 is disposed at the initial position (see FIG. 1). If the right door 12 is to be closed in this state, the contact portion 48 of the right fixing pin 38R contacts the first inclined surface 34 of the slide plate 26 of the right door 12.

  FIG. 3 shows a state immediately after the contact portion 48 contacts the first inclined surface 34. At this time, a reaction force F1 in a direction perpendicular to the first inclined surface 34 is generated with respect to the slide plate 26. The reaction force F1 can be decomposed into a force FL1 in the right door outer direction and a force FW1 in the right door tip direction. Of these, the force FW1 causes the slide plate 26 to slide toward the right door tip side against the elastic force of the spring 28. The reaction force FL1 is offset by the reaction force from the side portion 24B of the guide 24.

  When the slide plate 26 slides to the front end side of the door and the right door 12 is completely closed, the state shown in FIG. 4 is obtained. The slide plate 26 in this state has moved to the front end side of the right door 12 by a distance W1 compared to the initial position. The distance W2 in this figure includes an initial contact point P1 at which the first inclined surface 34 and the contact portion 48 first contact each other, and a final contact point P2 at which the right door 12 contacts completely with the right door 12 fully closed, The distance in the vehicle width direction is shown. The distance W1 and the distance W2 have substantially the same length (however, the right door 12 is not exactly the same because it rotates and moves).

  As shown in this figure, when the right door 12 is closed from the state in which both the right door 12 and the left door 14 are opened, the slide plate 26 of the right door 12 is at the front end side of the right door 12 by a distance W1 from the initial position. Moved to be placed. That is, the outer surface 32 of the slide plate 26 of the right door 12 is disposed so as to protrude by a distance W1 from the center line C of the door opening to the left door 14 side.

  The final contact point P <b> 2 of the first inclined surface 34 is the vertex P <b> 2 of the first inclined surface 34. For this reason, when the right door 12 is closed, the position of the slide plate 26 is fixed.

  In the above description, the operation of closing the right door 12 first from the state in which both doors are released has been described, but the same operation is performed when the left door 14 is closed first. In this way, even when any of the left and right doors is closed first, the door-side contact portion 48 to be closed first comes into contact with the first inclined surface 34 of the slide plate 26 of the door to be closed first, The slide plate 26 of the door to be closed first slides to the door front end side. That is, in the present embodiment, the first inclined surface 34 and the fixing pin 38 (the contact portion 48 thereof) constitute the “first slide means” of the present invention.

  Next, the operation when the left door 14 is closed from the state shown in FIG. 4 (the state where the right door 12 is closed and the left door 14 is opened) will be described.

  The left door 14 in an opened state is a state in which FIG. 1 is symmetric, and the slide plate 26 of the left door 14 is disposed at an initial position. When the left door 14 is to be closed in this state, the tip 30 of the slide plate 26 of the right door 12 that has been closed first comes into contact with the second inclined surface 36 of the slide plate 26 of the left door 14. That is, the slide plate 26 of the right door 12 that is closed first is protruded from the center line C to the left door 14 side by a distance W1, so that the left end of the slide plate 26 of the right door 12 that is closed after the left is closed. The contact is made with the second inclined surface 36 of the slide plate 26 of the door 14.

  FIG. 5 shows a state immediately after the front end 30 of the slide plate 26 of the right door 12 that has been closed first comes into contact with the second inclined surface 36 of the slide plate 26 of the left door 14 that is closed later. At this time, a reaction force F2 in a direction perpendicular to the second inclined surface 36 is generated with respect to the slide plate 26 of the left door 14 that is closed later. The reaction force F2 can be decomposed into a force FL2 in the left door 14 outer direction and a force FW2 in the left door 14 proximal direction. Of these, the force FW2 causes the slide plate 26 of the left door 14 to slide toward the base end side of the left door 14 against the elastic force of the spring 28. The reaction force FL2 is offset by the reaction force from the side portion 24B of the guide 24.

  Thereby, before the slide plate 26 of the left door 14 to be closed later contacts the left fixing pin 38, the slide plate 26 of the left door 14 moves to the left door base end side. As a result, the first inclined surface 34 of the slide plate 26 of the left door 14 is prevented from contacting the contact portion 48 of the left fixing pin 38.

  Thereafter, the second inclined surface 36 of the slide plate 26 of the left door 14 contacts the contact portion 48 of the left fixing pin 38. Also by this, the slide plate 26 of the left door 14 moves to the left door base end side, and when the left door 14 is completely closed, the state shown in FIG. 6 is obtained.

  As described above, the front end 30 of the door-side slide plate 26 that is closed first comes into contact with the second inclined surface 36 of the door-side slide plate 26 that is closed later. To slide to. That is, in the present embodiment, the second inclined surface 36 and the tip 30 of the slide plate 26 constitute the “second slide means” of the present invention. In this embodiment, it can be said that the fixing pin 38 (the contact portion 48 thereof) also constitutes the “second sliding means” of the present invention.

  As shown in FIG. 6, when the right door 12 is closed first and the left door 14 is closed later, the outer surface 32 of the slide plate 26 of the right door 12 is not only the seal rubber 22 of the right door 12 but also the left The seal rubber 22 of the door 14 is also in contact. In this state, the pair of seal rubbers 22 of the right door 12 and the left door 14 and the slide plate 26 of the right door 12 are in contact with each other with a certain level of seal pressure. For this reason, it is possible to prevent water or the like from entering between the right door 12 and the left door 14 by the slide plate 26 of the left door 14 and the pair of seal rubbers 22.

  Next, the operation when the right door 12 closed first is opened from the state shown in FIG. 6 (the right door 12 closed first and the left door 14 closed later) will be described.

  As shown in FIG. 6, the slide plate 26 of the right door 12 that has been closed first moves toward the left door 14, and therefore the locus of the slide plate 26 of the right door 12 when the right door 12 is opened is There is a door outer panel 18 of the left door 14.

  FIG. 7 shows a state where the right door 12 is slightly opened. As shown in this figure, when the right door 12 is slightly opened, the contact portion 48 of the right fixing pin 38 is separated from the vertex P2 of the first inclined surface 34 of the slide plate 26 of the right door 12. Here, an elastic force acts on the slide plate 26 of the right door 12 toward the right door base end side by the spring 28. Therefore, the slide plate 26 of the right door 12 moves toward the base end side of the right door 12 toward the initial position while the contact portion 48 of the right fixing pin 38R continues to contact the first inclined surface 34. As a result, the locus of the slide plate 26 of the right door 12 is disengaged from the door outer panel 18 of the left door 14, so that the right door 12 can be opened. At this time, as shown in FIG. 7, the sealing rubber 22 of the left door 14 is compressed, so that the right door 12 can be opened without any trouble.

  Here, in the present embodiment, the length L1 in the door inner / outer direction from the slide plate 26 to the distal end portion 18A of the door outer panel 18 is set longer than the length L2 of the first inclined surface 34 in the door inner / outer direction. . For this reason, the contact portion 48 of the fixing pin 38 is disengaged from the first inclined surface 34 before the tip 30 of the slide plate 26 of the right door 12 interferes with the tip 18A of the door outer panel 18 of the left door 14. As a result, the slide plate 26 returns to the initial position by the elastic force of the spring 28, so that the right door 12 can be opened without hindrance.

  Note that the slide plate 26 does not hinder the opening operation even when the left door 14 is opened after the state shown in FIG. 6 (the right door 12 is closed first and the left door 14 is closed later). The left door 14 is opened without any trouble. The operation at this time is substantially the same as the above-described operation--the operation when the left door 14 is closed from the state shown in FIG.

  All the operations described above are established even if the opening order of the right door 12 and the left door 14 is reversed. That is, in the double door 10 of this embodiment, the door opening / closing order is not limited. Further, in a state where both doors are closed, the pair of left and right seal rubbers 22 and the door-side slide plate 26 closed earlier are brought into contact with each other with a certain sealing pressure. Therefore, it is possible to prevent water or the like from entering the inside of the vehicle.

[Supplementary explanation of the above embodiment]
Note that the double door structure of the present invention can be applied to doors of various shapes. For example, as shown in FIG. 9A, the present invention can be applied to a door in which the shape of the door front end portion is linearly formed up to the upper end, and as shown in FIG. The present invention can also be applied to a door whose shape is bent at the upper end. At this time, the slide plate 26 has a straight portion 26A and a curved portion 26B. In this figure, the seal rubber and the like are omitted.

  In the above-described embodiment, the first inclined surface 34 and the fixing pin 38 (the contact portion 48) constitute the “first slide means” of the present invention, and the second inclined surface 36 and the tip 30 of the slide plate 26. However, the “first slide means” and the “second slide means” of the present invention are not limited to this. For example, the open / closed state of the door may be detected by a sensor or the like, and the slide position of the slide plate may be electrically controlled. In this case, the fixing pin 38, the first inclined surface 34, and the second inclined surface 36 are unnecessary.

  Further, in the above-described embodiment, a total of four fixing pins 38 are provided on the upper and lower sides in the vehicle up-down direction, but a pair of left and right sides. And the number arrange | positioned is not restricted to this. For example, a pair of left and right fixing pins may be provided only in the lower part in the vehicle vertical direction. Further, the pair of left and right fixing pins may be arranged with the height in the vehicle vertical direction being changed.

  In the above-described embodiment, the right door 12 and the left door 14 have substantially the same structure that is bilaterally symmetric, but the present invention is not limited to this. For example, the length from the base end to the front end of the right door may be different from the length from the base end to the front end of the left door. Moreover, a pair of doors may be arranged up and down.

  Moreover, although embodiment mentioned above applied this invention to the double door 10 provided in the vehicle rear part, this invention is not limited to this. That is, the present invention can be applied to a double door that has nothing to do with a vehicle.
