Abstract

PURPOSE:To contrive to strengthen an on-vehicle sliding door by providing a stopper which comes in contact with an locking section at the car body side on the back face of the extended rear end section of a door inside handle. CONSTITUTION:A side panel 3 is formed with an opening section 4 for installing a sliding door 2 as a platform. An auxiliary inside handle is arranged in a position which is hidden underneath an instrument panel 13 when the sliding door 2 is closed. The auxiliary inside handle 14 is formed into a L-shape while the lower end section of it is extended afterward wherein a stopper 15 made of an elastic material such as rubber and the like is fixed onto the rear face of its extended section. Which situation therefore allows the stopper 15 to come in contact with the side wall section 3a of the side wall panel 3 so as to let the sliding door 2 be locked when the auxiliary inside handle 14 is pulled out afterward. Impact applied to the stopper 15 is received by the whole of the auxiliary inside handle 14, local stress concentration can thereby be prevented.

Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a sliding door for an automobile.

b. Conventional technology There are two types of sliding doors installed in automobiles: the rectangular type used in wagon cars as shown in Figure 8, and the pentagonal type with short upper sides used in passenger cars as shown in Figure 9. There is one (Japanese Unexamined Patent Publication No. 57-44524).

The sliding door 100 has upper, middle and lower guide rails 101
Guide rollers are engaged with 102 and 103 via upper, middle, and lower support arms (not shown).

To open and close the sliding door 100 from inside the room, a door rotor inside side handle 1 provided on the indoor side of the door panel is used.
It is carried out by 04.

However, in the front door of a passenger car, when the sliding door 100 is closed as shown in FIG.
5, making opening and closing operations difficult.

Therefore, the door rotor inside handle 104 only releases the lock, and the sliding door 100 is opened by an auxiliary handle 106 provided at the bottom of the sliding door 100 as shown in FIG.

Then, a stopper 107 is placed on the back side of the sliding door 100.
is provided to limit the opening of the sliding door 100.

C1 Problems to be Solved by the Invention However, in the conventional sliding door 100, the 11th
If the sliding door 100 is violently opened as shown in the figure, stress will be concentrated on the screw 109 portion of the stopper 107 that fastens the bracket 108, and there is a risk that the door panel will be damaged. Therefore, it was necessary to take measures such as applying a reinforcing plate 110 to the inside of the door panel for reinforcement.

An object of the present invention is to solve the above-mentioned problems and provide a sliding door for an automobile that can obtain sufficient strength.

d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a sliding door for an automobile in which the front door is a sliding type, by extending the rear end of the inside door handle, and attaching a vehicle body side handle to the rear surface of the extended portion. The durability is improved by providing a stopper that comes into contact with the stopper.

e. Operation When the sliding door is opened, the stopper provided at the rear end of the extension of the door inside handle is locked to the vehicle body abutting part. Since the impact applied to the stopper is received by the entire inside door handle, it is dispersed and absorbed by the sliding door.

f. Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Figure 1 is a conceptual diagram showing the state with the sliding door removed.
Figure 2 is a conceptual diagram showing the sliding door in the middle of opening, Figure 3 is a perspective view of the sliding door from the indoor side, Figure 4 is a sectional view taken along line A-A in Figure 3, and Figure 5 is the door. FIG. 3 is a perspective view of the inside handle viewed from the back side.

In FIGS. 1 to 4, ``■'' is an automobile body equipped with a sliding door 2, and an opening 4 for attaching the sliding door 2 is formed in a side panel 3 as an entrance/exit. The sliding door 2 has the same shape as a normal passenger car door, and the length i of the upper side is shorter than the length m of the lower side, and the front of the upper side is formed obliquely.

An upper guide rail 5I and a lower guide rail 5. , and a middle guide rail 5□ extending in the same direction as the upper and lower guide rails 55 is provided on the side panel rearward from the rear side edge 4b.

Above upper guide rail 5. , a rear panel portion is formed from the upper edge 4a of the opening 4 so as to be flush with the upper edge 4a, and the upper guide rail 5. This is an extension of the . As a result, the upper guide rail 5.
Measure the length of the lower guide rail 5. and set to the same length.

6 is the upper guide rail 5. This is a quarter garnish provided on the outside of the roof panel 7, and is formed to have an external shape that is continuous with the roof panel 7. This quarter garnish 6 is provided with a stepped portion 9 at its lower edge to form a certain gap between it and the quarter glass 8.

On the other hand, the sliding door 2 has upper, middle and lower guide rails 5+.
, 5t, 5j, guide rollers 10+, 10□,
lOl is provided.

The sliding door 2 is opened and closed by an outside handle 11 provided on the front surface of the sliding door 2 and a door lock inside handle I2 provided on the back surface.

This door lock inside handle 12 is provided at a position where it does not interfere with the instrument panel 13. 1
Reference numeral 4 denotes an auxiliary inside handle provided at the front lower part of the back surface of the sliding door 2, and this is provided at a position hidden under the instrument panel 13 when the sliding door 2 is closed.

As shown in FIGS. 4 and 5, the auxiliary inside handle 14 is formed into an L-shape by extending its lower rear end rearward, and has a stopper 15 made of an elastic material such as rubber on the rear surface of the extension. It is installed. The auxiliary inside handle 14 is provided with a predetermined number of boss portions 14a, and is screwed to the inner panel 2a of the sliding door 2 via screws 16 to the boss portions 14a.

According to the automobile sliding door having the above configuration, when opening the door from inside the vehicle, the door lock inside handle 1
When the slide door 2 is unlocked and pulled rearward by the auxiliary inside handle 14, the stopper 15 of the slide door 2 is locked against the side wall 3a of the side panel 3 of the vehicle body.

Then, the sliding door 2 opens the entrance by a predetermined width for boarding and alighting. Since the impact applied to the stopper 15 is received by the entire auxiliary inside handle 14, partial concentration of stress on the inner panel 2a of the sliding door 2 is prevented.

When attaching the stopper 15, the stopper 15' may be attached to the bracket 17 as shown in FIGS. 6 and 7, and the bracket 17 and the auxiliary inside handle 14 may be screwed to the inner panel 2a.

Furthermore, a small reinforcing plate 18 may be provided on the back surface of the inner panel 2a.

g. Effects of the Invention As described above, according to the sliding door for an automobile according to the present invention, the entire auxiliary inside handle receives the impact applied to the stopper when the sliding door is opened, so that local concentration of stress can be prevented. .
