  SUMMARY OF THE INVENTION An object of the present invention is to provide a tailgate integrated slope device that is effective in making the slope portion compact, and that ensures space in the luggage compartment and improves the rear view.

A slope device integrated with a tailgate according to the present invention is a slope device formed integrally with a tailgate, which is provided at a rear portion of a vehicle body, and is rotatable in an upright state and a rearward open state. A pair of slide groove portions in the front-rear direction are formed on both sides in the left-right direction, a tail gate rail is disposed along the slide groove portion inside the tail gate, and a first fitting portion with the tail gate rail is provided. A pair of left and right first slide rails extending from the first fitting portion to the indoor side of the tailgate indoor side panel via the slide groove, and between the pair of first slide rails, the tailgate The first panel is fixed to the indoor side of the indoor side panel, and the first panel is extendable and retractable along the tailgate rail.
In this specification, the indoor side means the vehicle body indoor side in a state where the tailgate (slope part) is raised, and the left-right direction means the vehicle width direction.

  Further, the present invention is not limited to the two stages of the tailgate and the first panel, and each has a second fitting portion on the indoor side of the first panel of the pair of first slide rails, There are a pair of left and right second slide rails that are slidably fitted to the second fitting portion, and a plurality of stages are arranged in three or more stages so as to fix the second panel between the pair of left and right second slide rails. The panel may be formed to be slidable.

  Here, if a pair of ridge-shaped anti-wheel prevention portions are formed in the front-rear direction on the left and right sides on the tailgate room side, the risk that a wheelchair or the like traveling on the slope surface will de-wheel is reduced.

In the slope device according to the present invention, the tail panel rail is provided in the interior of the tailgate, with the first panel disposed on the interior surface of the tailgate while using the interior panel of the tailgate as a slope surface. Since it can be extended and contracted along the side, high rigidity can be secured while making the slope portion compact.
In addition, when a plurality of slopes are formed on the tailgate, such as by providing a second panel slidably with respect to the first panel, the slope storage protrudes from the top of the tailgate when the tailgate is raised. The height can be lowered and the rear field of view is improved.

The state where the tailgate is opened rearward and the panel is pulled out is shown. Sectional drawing of each rail part is shown. The panel is stored and the tailgate is closed (standing up). The state where the tailgate is opened while the panel is stored is shown. The other structural example of a slide rail at the time of making a slope surface into three steps is shown.

A structural example of a tailgate integrated slope according to the present invention will be described below with reference to the drawings.
FIG. 3 shows a state in which the rear door 2 of the vehicle body is opened. In this state, the tailgate 1 is erected and a panel for forming a slope is accommodated on the indoor side.
FIG. 4 shows a state in which the tailgate 1 is opened rearward with the panel stored.
FIG. 1 shows a state in which the first panel 20 and the second panel 30 are pulled out from the tailgate 1 and extended, and the tip side of the second panel 30 is grounded to the ground or the like to form a slope.
FIG. 2 shows a cross-sectional view of the main part of the rail part.

The indoor side panel 10 is provided on the indoor side of the tailgate 1, and slit-like slide grooves 10a extending in the front-rear direction are provided in the vicinity of both left and right ends of the indoor side panel 10.
A tailgate rail 11 fixedly connected to the inside of the indoor panel is provided inside the tailgate along the slide groove 10a.

The first panel 20 slides and expands along the indoor side of the indoor side panel 10 of the tailgate 1, and an example of the rail structure is shown in FIG.
A pair of first slide rails 21 are fixedly coupled to the left and right ends of the first panel 20 so as to face each other.
The first slide rail 21 has a first fitting portion 21a with the tailgate rail 11 provided inside the tailgate 1, and from the first fitting portion via the slide groove 10a of the indoor side panel 10, It has the connection part 21c with 1 panel, and is an example which has the 2nd fitting part 21b with the 2nd slide rail 31 further in a present Example.
The first fitting portion 21a and the second fitting portion 21b may have any structure that can be fitted and slid with the tail gate rail 11 and the second slide rail 31 that are the other side rails. As long as the other is a concave groove in the ridge, either may be a ridge.
In the present embodiment, the first slide rail 21 has a substantially E-shaped cross section, and has a concave groove-shaped second fitting portion 21b facing the facing surface on the upper side (inner side) and a substantially U-shaped cross section on the lower side. This is an example of a recessed groove-shaped first fitting portion 21a that is fitted to the tailgate rail 11 having a shape portion.
In this embodiment, a second panel 30 is fixed between a pair of left and right second slide rails, the second panel 30 slides along the indoor side of the first panel 20, and the first panel 20 has a tail. Slide along the indoor side surface of the indoor side panel 10 of the gate 1.
Therefore, as shown in FIG. 1, the interior side panel, the first panel 20 and the second panel 30 of the tailgate 1 are extended, and the tip of the second panel 30 is grounded to the ground or the like so that a gentle slope surface is formed. Can be formed.
On the other hand, the second panel 30 is accommodated so as to overlap the indoor side of the first panel 20, and the first panel 20 is accommodated so as to overlap the indoor side of the indoor side panel 10 of the tailgate 1. As shown, the amount of slope protrusion from the upper part of the tailgate 1 is suppressed, and the rear view is improved.

In the present embodiment, a pair of ridge-shaped anti-wheel preventing portions 1a are provided in the vicinity of the left and right ends of the indoor side panel 10 of the tailgate 1, and in this way, the indoor side of the tailgate 1 is provided. The effective width of the first slope surface on the vehicle side that is close to the full left and right width can be obtained.
In the present embodiment, the derailment prevention portion 1a has a protruding piece shape in which the left and right side wall portions of the tailgate 1 are extended to the indoor side as they are, and has a slope width close to the tailgate opening width.

The present invention is characterized in that a rail on which the first slide rail 21 of the first panel forming the second slope surface is fitted and slid from the vehicle side is provided inside the tailgate 1 as the tailgate rail 11. However, as in this embodiment, when the third slope surface is further provided in three steps, the following characteristics are obtained.
Assuming a case where the lowermost slide rail connected to the vehicle side is sequentially fitted and formed in three stages without using the inside of the tailgate, for example, as shown in FIG. The rails 102 are arranged, and the upper rails 103 are arranged inside the rails 102, and a panel material is connected to each rail.
However, such a structure increases the fitting width dimension W ₁ between the rails, there is a problem of relatively third effective width W ₀ of the slope surface of the smaller.
On the other hand, in this embodiment, as shown in FIG. 2, the cross-sectional shape of the first slide rail 21 for forming the second slope surface is formed in an approximately E shape, and the third slope surface is formed. The first fitting portion 21a can be formed on the lower surface side of the first panel 20 just below the second fitting portion 21b with the second slide rail 31 for the structure shown in FIG. dimension W ₁ is smaller than that in the.
Accordingly, the effective width dimension W ₀ of the second panel 30 can be relatively increased.
That is, in the present invention, since the tailgate rail 11 is provided inside the tailgate 1 and the interior panel 10 is used as a slope surface, it is not necessary to sequentially fit in the lateral direction as shown in FIG. is there.

Further, as shown in FIG. 1, when the first slide rail 21 is pulled out from the tailgate rail 11 and the second slide rail 31 is further pulled out from the first slide rail 21 and a three-step slope surface is formed, The applied load tends to concentrate on the overlapping portions L ₁ and L ₂ of the rails.
In the present embodiment, as shown in FIG. 2, the first fitting portion 21a and the second fitting portion 21b are formed substantially vertically above and below the first slide rail so that the dimension H becomes relatively large. Thus, the bending strength in the vertical direction of the first slide rail 21 is improved.
On the other hand, since the tailgate rail 11 is connected to the inside of the tailgate 1, the load can be propagated to the vehicle body side.
Therefore, since the lapping margins L ₁ and L ₂ can be made smaller than the structure shown in FIG. 5, the storage height when the slope surfaces are placed in an upright state can be kept low.

In the slope device according to the present invention, as shown in FIG. 2, the slide grooves 10 a provided on the left and right sides of the indoor side panel 10 of the tailgate 1 are formed from the rising portion a of the second slide rail 31 from the second panel 30. If it is provided outside, there is no fear that the wheelchair or the legs of the assistant will be caught in the slide groove 10a, which is safe.
In addition, when the slide groove 10a is provided on the inner side of the outer position b of the first slide rail 21, the first fitting portion 21a is positioned almost directly below the first slide rail 21, and the width of the first slide rail 21a is the largest. it is possible to increase the effective width W ₀ of the second panel 30 to form a narrow third slope surface.
