Description

[Detailed description of the invention] In this invention, when the door is fully closed, the outside surface becomes flush with the outside surface of the car body, and when the door is opened, it is guided by the inclined guide part of the guide rail provided on the car body and flies out to the outside of the car body. The present invention relates to a door holding device for holding a sliding door in a fully open state, which is guided by a slide opening/closing portion of the guide rail parallel to the outside surface of the vehicle body and slid open and closed along the outside surface of the vehicle body.

As shown in Fig. 1, the sliding door 1 usually has three
At points A, B, and C, the vehicle body 2 is supported so that it can be slid open and closed along the outer surface 21 of the vehicle body, and when the door is opened, the sliding door closes unexpectedly and the body becomes caught between the vehicle body and the sliding door. It is equipped with a door opening holding device that holds the door open to prevent accidents. As a conventional door opening holding device, there is one shown in FIG. 2, for example.

That is, the vehicle body 2 is provided with a guide rail 3, and a guided member 4 guided by the guide rail 3 is pivotally attached to the rear of the sliding door 1 so that it can swing when the door is fully closed. In this case, the outer surface 11 of the sliding door I is the outer surface 21 of the vehicle body.
The guided member 4 is stored between the guide rail 3 and the inner panel 12 of the sliding door I (the state shown on the left side of FIG. 2) so that the guided member 4 is on the same plane as the door opening operation. Sometimes, the sliding door 1 is moved out of the vehicle body from the stored state along the inclined guide portion 31 of the guide rail 3, and then the guide rail 3 is moved parallel to the outer side surface 21 of the vehicle body.
The sliding door 11 along the sliding opening/closing part 32 of
(the state shown in the center of FIG. 2), and when the door is fully open, the guided member 4
A stopper lever 5 pivotally supported by the stopper lever 5 engages with a stopper 22 provided on the vehicle body 2 by its biasing force (the state shown on the right side of Fig. 2), and holds the sliding door 1 in the fully open state. It is.

However, in such a conventional door opening holding device, when the door is closed, the stopper lever is released by operating the stopper release member 6 provided on the sliding door 1 and connected to the stopper lever 5 by a transmission member 61. 5 from the stopper 22 and then slide the sliding door 1 along the guide rail 3 in the door closing direction, when the guided member 4 passes the inclined guide part 31, the inclined guide part 31 (the posture of the guided member changes from the state shown in the center of FIG. 2 to the state shown on the left side of FIG. 2), the stopper lever 5 swings along the rail trajectory of the guided member. Since it rotates following the guide member 4 (the posture of the stopper lever changes from the state shown in the center of FIG. 2 to the state shown on the left side of FIG. 2), the stopper lever 5 and the stopper release member 6 are An unreasonable load may be applied to the connecting transmission member 61, which may deform the transmission member 61, and the deformed transmission member 61 may interfere with built-in components such as glass inside the sliding door 1.
There has been a problem in that the closing operation force required to bring the device into the fully closed state may increase due to the pricking phenomenon.

Furthermore, in the conventional door opening holding device, the guided member 4 and the stopper lever 5
If the stopper release member 6 is operated by mistake when the door is fully closed and the door is stored between the guide rail 3 and the inner panel 12, the stopper lever 5 will move from the state shown on the left side of FIG. Since it can be rotated in the direction, the stopper lever 5
There is a risk that the inner panel 12 may be deformed or its paint may peel off due to interference with the inner panel 12, or that abnormal noise may be generated due to the interference.

The present invention has been made by focusing on such conventional problems, and includes interposing a relay operating lever between the stopper lever and the stopper release member to relay the stopper release operation by the stopper release member to the stopper lever. The aim is to solve the above problems.

In order to achieve such an object, in the present invention, a relay operating lever is interposed between a stopper lever that engages with a stopper provided on the vehicle body and a stopper release member provided on the sliding door, so that when the door is fully opened, The release member and the stopper lever are connected so that the stopper release operation by the release member is transmitted to the stopper lever via the relay operating lever, and the guided member guided by the guide rail provided on the vehicle body is in the fully closed state of the door. The stopper lever and the release member are arranged so that the stopper lever gradually separates from the relay operating lever as it is guided by the inclined guide portion of the guide rail.

Embodiments of the present invention will be described below based on the drawings. Note that the same parts as in the conventional example are given the same reference numerals.

FIG. 3 shows a first embodiment of the present invention, in which the sliding door 1 is moved between a fully closed state and a fully open state along the outer surface 21 of the vehicle body 2 at three locations A, B, and C shown in FIG. A guide rail 3 is provided on the vehicle body 2 so that the guided member 4 is guided and supported so as to be slidable and openable between the sliding door 1 and the sliding door 1. It is pivoted.

The guide rail 3 is formed parallel to the outer side surface 21 of the vehicle body so that the sliding door 1 can be slid open and closed along the outer surface 21 of the vehicle body with the outer surface 11 of the sliding door I protruding from the outer surface 21 of the vehicle body. a sliding opening/closing part 32, and an inclined guide part for displacing the sliding door 1 from a position where the outer surface 11 protrudes from the outer surface 21 of the vehicle body to a position where the outer surface 11 is flush with the outer surface 21 of the vehicle body. 31.

The guided member 4 includes rollers 41 and 42 that are rotatable in a horizontal plane (plane of paper), a bearing 43 that is rotatable in a vertical plane, and rollers 41 and 42 that are rotatable in a vertical plane.
and a roller mount 44 that rotatably holds a bearing 43, and the rollers 41, 42 and the bearing 43 are rotatably engaged with the guide rail 3. The roller frame 44 is connected to the slide door I by the rotating shaft 13.
It is pivotally mounted to a mounting portion 14 fixedly attached to the mounting portion 14 so as to be swingable within the horizontal plane.

A stopper lever 5 is pivotally supported on the roller frame 44, and when the slide door 1 is fully opened, a hook portion 51 of the stopper lever 5 is attached to a stopper 22 provided on the vehicle body 2 with a spring member 52.
They are configured to engage with each other by the urging force of.

Further, a relay operating lever 7 is pivotally mounted on the roller mount 44 by the rotating shaft 13, and one end 71 of the relay operating lever 7 transmits a tensile force to the stopper release member 6 provided on the sliding door 1. In the compression direction, they are connected by a rigid transmission member 61.

Then, in the door fully open state where the stopper lever 5 is engaged with the stopper 22 (the state shown on the right side of FIG. 3), the stopper release member 6 is operated in the stopper release direction (towards the left in the figure). operation), the tip 72 of the relay operating lever 7 presses the engagement surface 53 of the stopper lever 5, thereby rotating the stopper lever 5 clockwise against the biasing force of the spring member 52, thereby causing the stopper lever to rotate. The stopper release member 6 and the stopper lever 5 are connected via a relay operating lever 7 so that the stopper lever 5 can be disengaged from the stopper 22.

Furthermore, regarding the engagement relationship between the tip end 72 of the relay actuation lever 7 and the engagement surface 53 of the stopper lever 5, the clockwise rotational movement of the relay actuation lever 7 is transmitted to the stopper lever 5; The relay operating lever 7 and the stopper lever 5 are arranged so that the clockwise rotational movement of the lever 7 is not transmitted to the relay operating lever 7.

That is, from the state in which the rollers 41 and 42 have entered the inclined guide portion 31 (the state shown second from the left in FIG. 3), the rollers 41 and 4
2 moves inside the inclined guide part 31 toward the fully closed state of the door, the roller mount 44 rotates clockwise together with the stopper lever 5, so that the engagement surface 53 of the stopper lever 5 engages with the relay operating lever 7. The relay operating lever 7 and the stopper lever 5 are arranged so that they gradually separate from the tip 72 and the distance between the engagement surface 53 and the tip 72 gradually increases.

Next, the action will be explained.

Door fully open (shown on the right side of Figure 3)
In this case, the hook portion 51 of the stopper lever 5 engages with the stopper 22 to hold the slide door 1 in the open state, and from this state, the stopper release member 6 is operated in the stopper release direction to close the door (see Fig. (toward the middle left), the transmission member 6
1 rotates the relay actuation lever 7 clockwise, and the tip 72 of the relay actuation lever 7 pushes the engagement surface 53 of the stopper lever 5, so that the stopper lever 5 resists the biasing force of the spring member 52 and rotates clockwise. The hook portion 51 is disengaged from the stopper 22, and the engagement between the hook portion 51 and the stopper 22 is released.

After releasing the engagement, the sliding door 1 is slid along the outer side surface 21 of the vehicle body in the door closing direction. In this state, the roller 4
1 and 42 are guided by the slide opening/closing portion 32 of the guide rail 3 (the state shown second from the right in FIG. 3).

Then, from the state in which the rollers 41 and 42 have entered the inclined guide portion 31 of the guide rail 3 (the state shown second from the left in FIG. 3), the slide door 1 is further turned to the fully closed state. When slid, as the rollers 41 and 42 advance along the inclined guide section 31, the roller mount 44 rotates clockwise together with the stopper lever 5, so that the engaging surface 53 of the stopper lever 5 engages with the relay operating lever 7. It gradually separates from the tip 72, and the amount of separation between the engagement surface 53 and the tip 72 gradually increases.

When the door is fully closed (the state shown on the left side of FIG. 3), the stopper lever 5 is connected to the guide rail 3 and the inner panel with its engagement surface 53 spaced apart from the tip 72 by a predetermined distance. It is stored between 12 and 12.

FIG. 4 shows an enlarged view of a second embodiment of the present invention.

In the second embodiment shown in FIG. 4, the stopper lever 50 and the relay operating lever 70 are pivotally supported by the same rotating shaft 13, and the stopper lever 50 has an engaging pin 55 that engages with the stopper 22.
The other configuration except that
This is similar to the example.

That is, when the release member 6 is operated in the release direction with the door fully open (the state shown on the right side of FIG. 4), the tip 75 of the operating lever 70 presses the engagement surface 56 of the stopper lever 50. As the stopper lever 50 is rotated clockwise and the rollers 41 and 42 move inside the inclined guide portion 31 toward the door fully closed state (the state shown on the left side of FIG. 4), the engagement surface 56 is rotated clockwise. The stopper lever 50 and the relay actuation lever 70 are arranged so that the stopper lever 50 and the relay operating lever 70 gradually separate from the tip portion 75.

According to the door opening holding device for a sliding door according to the present invention, a relay actuation lever is interposed between a stopper lever and a stopper release member, and when the door is fully opened, the stopper release operation by the release member is performed via the relay actuation lever. The stopper lever and the stopper release member are arranged so that the stopper lever is gradually separated from the relay operating lever as the guided member is guided by the inclined guide portion of the guide rail toward the fully closed state of the door. Because of this, no unreasonable load is applied to the transmission member that connects the stopper release member and the relay operating lever.

Further, according to the present invention, by appropriately setting the amount of separation between the tip of the relay operating lever and the engagement surface of the stopper lever when the door is fully closed, the stopper lever can be moved even if the stopper release member is operated when the door is fully closed. can be prevented from interfering with the inner panel of the sliding door.
