DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a sliding door used in a vehicle or the like in which a plurality of doors are arranged in parallel, and when the doors are opened and closed, adjacent doors move in conjunction with each other at ends. is there.

[0002]

2. Description of the Related Art When a door of such a sliding door is closed, a fitting portion b having a gasket c is provided at an end of each door a as shown in FIG. Engagement makes the door joints interlocking and waterproof. However, in this structure, the interlocking structure was not established unless the gap s between the adjacent doors a was large. When a structure in which a plurality of sliding doors are combined is required depending on the vehicle application, there is a problem that the gap s significantly reduces the inner dimension. FIG. 8B shows the engagement relationship of the door ends when the sliding door is opened.

[0003]

In view of the problems of the prior art, (1) to reduce the distance between adjacent doors as much as possible and to increase the inner dimension of a vehicle or the like as much as possible; (2) doors (3) The contact surface of the interlocking part is elastic so that the gasket can contact the side surfaces of the doors adjacent to each other only when the door is closed to ensure smooth opening / closing and watertightness when closing. (4) The end members, which are the contact surfaces between the doors, are formed of a rigid material, and the ends of the end members are made of a rigid body. A sliding door capable of alleviating the impact at the time of contact and preventing the generation of noise when the door receives force from either direction, with a gasket interposed between the members. To It is an object of the present invention to provide.

[0004]

In a sliding door structure in which a plurality of doors are arranged in parallel and adjacent doors are sequentially moved in conjunction with each other by an interlocking mechanism provided at an end of each door at the time of opening and closing, the interlocking mechanism is an end of the door. A frame member attached to the frame member, and an end member fitted to an end of the frame member. The end member of the door has an end flat surface and inward projections orthogonal to the end flat surface on both sides of the end flat surface. Has,
A gasket made of an elastic material is mounted between the inward projection and the side surface of the frame material inserted into the front and rear ends of the door, and the gasket is provided in the gap b between the adjacent door and the frame material of the door when the door is not interlocked. When the end member and the end member interfere with each other and interlock with each other, the gasket is pinched between the projections of the opposed end members or between the projection and the flat surface of the end portion, and the gasket stands upright. It was in contact with the side of the material. Also, the height 7 'of the gasket when not interlocking is smaller than the gap size 7 between the frame members fitted to the front and rear ends of the door, and when the end members interfere with each other, the gap between the projections or the flatness between the projections and the end members is reduced. The gasket is pressed between the surfaces so that the tip of the gasket contacts the frame material of the adjacent door to seal the interlocking portion.

[0005]

FIG. 4 (a) shows four doors, namely, a first door.
FIG. 4B is a plan view showing a state in which a sliding door a including a door to a fourth door (a1, a2, a3, a4) is opened, and FIG. FIG. 5 is a longitudinal sectional view of the sliding door (an intermediate portion is omitted). FIG. 6 is a perspective view when the sliding door is provided at the rear of the vehicle, and FIG. 7 is a perspective view when the sliding door is provided at the side of the vehicle. Hereinafter, the interlocking mechanism will be described with reference to FIGS. FIG. 1A shows the tip of the first door a1. First door a1
A waterproof gasket 1 that hits a column or the like (not shown) when the tip is closed is fitted to the tip of a tip member 2 made of an extruded aluminum material. The first door a1 at the front end has a front end member 2 to which the gasket 1 is attached, and a main body member 3 fitted to a rear portion of the front end member 2. The rear end of the main body member 3 has the same structure as the right end of the second door a2 shown in FIG.

Next, the structure of the interlocking mechanism of the sliding door is shown in FIG.
A description will be given based on (B). FIG. 1B shows an interlocking configuration of a staggered portion between the second door a2 and the third door a3. Since the interlocking mechanism between the third door a3 and the fourth door a4 is the same, the interlocking mechanism between the second door a2 and the third door a3 will be described below with reference to FIG. . The fourth door a4 has one end fixed to a frame as shown in FIG.

The second door a2 includes a front frame member 4a and a rear frame member 4b, a main body member 3 fitted and mounted between the front frame member 4a and the rear frame member 4b, and front and rear side members inserted into ends of the frame members 4a and 4b. And the end member 5. The front frame material and the rear frame material 4
a and 4b have the same structure. The front and rear end members 5 also have the same structure. The end surface of the end member 5 forms a flat surface, and projections 6 orthogonal to the flat surface of the end member 5 are provided on both sides of the flat surface in parallel with the side surface of the door.

A gap 7 is provided between the inner surface of the projection 6 and the side surface of the front frame member 4a or the rear frame member 4b. A base 8b (FIG. 3) of a gasket 8 is mounted in the gap 7, and is fitted so that the tip thereof faces obliquely upward. As shown in FIG. 3, the gasket 8 includes a base 8b and a flexible oblique side 8a integral with the base 8b. The length l1 of the oblique side 8a is determined by a gap between the front frame member 4a or the rear frame member 4b. 7 is approximately 1.4 to 1.5 times as long. However, when the door is not interlocked, the tip of the gasket 8 is separated from the side surface of the frame material. That is, 7 '<7 in FIG.

FIG. 1B shows a state in which the door a2 closes away from the door a3 in the direction of the arrow X (leftward in the figure). As shown in the drawing, when the door a2 moves in the direction of the arrow X and the end member 5 on the door a2 side approaches the end member 5 on the door a3 side, the tips of the oblique sides 8b of the gasket 8 first come into contact. When the door 6 further moves in the X direction, the projections 6 on the door a2 side and the door a3 side come closer to each other, and the gasket 8 is pinched between the front ends thereof, so that the hypotenuse 8b is in a vertical state (FIG. 1C).

As described above, since the gaskets 8 stand upright and come into contact with each other, the projections 6 do not directly abut each other.
In other words, since the gasket 8 is interposed between the protrusions 6 and serves as a buffer, the collision noise is reduced. Further, the gaskets 8 are pushed together and stand upright, and the leading end stands up toward the front frame member 4a or the rear frame member 4b of the mating door, and comes into contact with the side surface of the frame material of the mating door. Water can be prevented from entering from the part.

Next, as shown in FIG. 2, when the door a2 is moved in the direction of opening in the direction of arrow Y (right side in the figure),
The protrusion 6 of the second end member 5 moves toward the front flat surface of the end member 5 of the inner door a3, and causes the inner door to interlock. Also at this time, since the gasket 8 of the door a2 comes into contact with the end face of the end member 5 first, there is no direct contact between the end member 5 and the end member 5, so that the collision noise is reduced.

When the outermost door a1 of the open sliding door is pulled to the left in the drawing as shown in FIG. 4A, the rear end member 5 of the door a1 becomes the front end member of the second door a2. 5 and are sequentially interlocked and closed as shown in FIG. Similarly, at the time of closing, the end member 5 acts on the other side via the gasket 8 and interlocks. Reference numeral 9 in FIG. 5 shows a traveling rail above each door. The upper part of the door is suspended by a suspension rail 9, and the lower part is guided by a lower rail 10 to be opened and closed quietly.

As described above, the sliding door structure including a plurality of doors can reduce the gap between the doors and prevent the load volume from being reduced. However, the sliding door structure of the two-piece sliding door will be described above. The same effect can be expected by applying the sealing structure in the interlocking portion of the sliding door.

[0014]

When the door is opened, the end member 5 of the adjacent door interferes and interlocks. However, the gasket 8 mounted between the end member 5 and the frame member is interposed between the end member 5 and the end member 5 interlocking. The opening and closing is smooth and quiet because there is no direct metal contact with the other party's door.

When the adjacent doors interfere and interlock with each other, the gasket rises and the tip of the gasket comes into contact with the inner surface of the frame, so that waterproofing can be achieved. Until the end members interfere, the gasket does not contact the mating door, so there is no resistance when opening and closing.

Further, since only the upright dimensions of the gasket need to be taken into account, the distance between the doors can be reduced, and in a vehicle or the like, the reduction in the load capacity can be reduced.
