Description

[Detailed Description of the Invention] This invention relates to the structure of an automobile door, and more particularly, to the structure of a door in which a window frame with a sheet-like window member attached thereto is detachably attached to the door body.

For example, some four-wheel drive vehicles designed to be suitable for off-road driving have a hood that covers the passenger compartment and a front window that can be folded forward. If you remove the front window, tilt the front window forward, and remove the door window frame, you can create a fully open car with nothing separating the upper part of the cabin from the outside air.

As a method for making the door of such a car removable with a wind frame, the conventional method was
As shown in Publication No. 56-51622,
The window frame itself consists of a sheet-like canopy with a transparent window attached to a frame made by bending steel pipes or steel bars into an inverted U shape, and the legs of the frame can be inserted and removed from the top of the door body. It is known to insert it into the

A simple wind frame like this, which is simply a canopy stretched over a frame made of steel pipes or steel bars, has the advantage of being safe, not having to worry about it breaking like glass, and being lightweight and cheap. Since it is actually impossible to attach a weather strip for sealing between the door opening and the door, there is a problem in that it is not possible to completely seal between the door opening and the door.

This invention was devised under the above circumstances, and its purpose is to allow the hood-shaped window formed at the top of the door body to be easily removed from the door body; Moreover, it is an object of the present invention to provide a structure of an automobile door that can maintain a high degree of sealing performance against the door opening of the vehicle body when the window portion is attached to the door body.

In order to achieve such an objective, the following technical measures are taken in the structure of the automobile door of the present invention.

That is, in the present invention, a sheet material is stretched over a frame-shaped core material that can fit into the groove of a wind frame having a groove on the inner periphery and a weather strip pasted on the outer periphery. The window member is attached by fixing the core material positioned in the groove and the window frame to each other with screws, and the window frame with the window member is detachably attached to the door body. It is characterized by

The window member according to the present invention is formed by stretching a sheet material onto a frame-shaped core material instead of the door glass in a normal automobile. Therefore, when this door structure is applied to, for example, an automobile for driving off-road, it is safe because there is no fear that the door will break like glass even if an external object such as a stone hits the window. In addition, the wind frame in the door structure of the present invention has a concave groove on the inner periphery, so it has a relatively large section modulus and high rigidity against bending. A weather strip is attached to seal between the window and the window frame, ensuring a good seal inside the cabin when the door is closed, and also reducing vibration of the wind frame due to negative pressure on the outside of the window.
Moreover, with the door structure of the present invention, the window frame can be removed from the door body, so the automobile can be easily converted into an open car.

Embodiments of the present invention will be specifically described below with reference to the drawings.

As shown in FIG. 1, the door 1 of the present invention is divided into a lower half of the door body 2 and a window frame 3 that forms a window. It is designed so that it can be attached and detached as needed.

The wind frame 3 includes a front frame 4 extending diagonally downward and forward, and a horizontal frame 5 extending rearward almost horizontally from the upper end of the front frame 4.
and a rear frame 6 that extends downward almost vertically from the rear end of the horizontal frame 5. As shown in cross section in FIG. 2, it has a groove 7 on its inner periphery. A general wind frame can be used that has a flange 8 provided on the outer periphery so as to be continuous with the outer end surface of the frame in the vehicle width direction. In the case of a door incorporating a normal elevating door glass, a glass run is fitted into the recessed groove 7, which plays the role of guiding and holding the elevating door glass, but in the present invention, a special window member described later is used. It serves as a groove to hold the edge of 9. In this example, the wind frame 3 is attached to the door body 2 using a substantially triangular bracket 11 that can overlap the indoor side surface of a triangular portion 10 provided in front of the upper edge of the door body 2.
is welded and fixed to the lower end of the front frame 4, and this bracket 11 is fixed with screws 12 so as to overlap the triangular part 10, while an extension part 13 is provided at the lower end of the rear frame 6 and this is attached to the door body 2. The inner panel 15 of the door body 2 is inserted and fixed into the insertion opening 14 formed at the rear of the upper edge, and is branched from the vicinity of the lower end of the rear frame 4.
This is done by fixing a bracket 16 extending along the upper part of the indoor side surface to the inner panel 15 with screws 17. The extension portion 13 inserted into the insertion port 14 is also fixed to the inner panel 15 with screws 18. Furthermore, a weather strip 19 is attached to the outer periphery of the wind frame 3, as shown in FIG.
9 elastically contacts the inner surface of the door opening to maintain airtightness in the room.

Now, inside the wind frame 3 above,
A window member 9 made of a sheet material 21 stretched over a core material 20 is attached.

That is, this window member 9 is a plate having a predetermined width and bent into a gate shape so as to fit into the groove 7 of the wind frame 3, and approximately corresponding to the shape of the wind frame 3. A sheet material 21 cut to correspond to the window space surrounded by the core material 20 is stretched around a core material 20 of the shape of the shape, and the core material 20 is wrapped around the bag portion 22 formed at the peripheral edge of the sheet material 21, as shown in FIG. Heartwood 2 as shown in
Pass the countersunk screw 25 inserted from the outside into the screw through hole 24 drilled in the wind frame 3 through the through hole 23 drilled at an appropriate location in the bag section 22 that wraps it, and insert the nut 26 into the threaded portion of the countersunk screw 25. It is attached to the wind frame 3 by tightening.

In addition, as shown in detail in FIG. 3, the core material 20
Both ends of a tension coil spring 28 wrapped in a tube-shaped mantle member 27 are fixed between the front and rear legs 20a, 20b, so that the front and rear legs 20a, 20b approach each other in a natural state. However, this core material 20 or bag portion 22 is inserted into the groove 7 of the front frame 4 and rear frame 6.
This is to improve workability when fitting from the inside.

Note that the sheet material 21 may be made of any material such as a hood material, a resin sheet, or a cloth material, and as shown in FIG.
It is convenient to allow a portion of the window to be opened, as this allows the window to be opened easily.

4 and 5 show a state in which the front frame 4 is attached to the triangular portion 10 on the door body side.

A screw hole 31 is bored in the inner panel 30 of the triangular portion 10, and a nut 32 is welded and fixed to the back side of the inner panel 30, and the bracket 11 fixed to the tip of the front frame 4 is
As shown by the arrow in FIG. 5, the screw 12 is overlapped with the triangular portion 10 from the passenger compartment side and passed through the screw through hole 33 which is bored so as to correspond to the screw through hole 31. From the above nut 32
It is fixed by tightening it. Furthermore, the fifth
As is clear from the figure, the bracket 11 has vehicle width direction pieces 11a and 11b formed not only to overlap the side surface of the triangular part 10 on the side of the vehicle interior but also to embrace a part of the front part and the rear part thereof. is formed, so that the front frame 4 is prevented from moving in the front-back direction when attached. Of course, since the bracket 11 having a relatively large area is overlapped with the triangular part 10 so as to correspond to the triangular part 10, the mounting rigidity of the front frame 4 can also be maintained at a high level. Further, since the lower end of the front frame 4 ends at the upper end of the triangular portion 10, the edge core material 20 or bag portion 22 of the window member 9 located below it is connected to the vehicle width direction piece 11b of the bracket 11. It is fixed by flat head screws 25.

FIG. 6 shows a state in which the rear frame 6 is attached to the door body 2.

As is clear from this figure, in the illustrated example, the rear frame 6 has an extension portion 13 thereof and a rear frame 6
A bracket 1 extends while being displaced in the vehicle width direction from
Since it is fixed to the door body 2 at two points 6, it is extremely strong against forces that try to bend the frame 6 in the vehicle width direction. As a result, it is possible to maintain a high degree of sealing performance between the door and the door opening.

As explained above, the structure of the automobile door of the present invention is that instead of door glass, a window member with a sheet material attached to the core material is attached, so there is no fear of it breaking due to impact unlike glass, and it is safe. It is. Further, since the window frame to which the above-mentioned window member is attached can be attached to and detached from the door body, by removing the window frame, the user can easily enjoy the pleasure of driving as an open car. Furthermore, by adopting a rigid metal wind frame, the seal between the wind frame and the door opening is very good when the vehicle is running with the door closed. In addition, the window frame is exactly the same as that of a door that incorporates a normal elevating door glass, and the window member can be removed from the wind frame, so the elevating door glass can be lowered. If the structure of this invention is adopted for the door body,
Depending on your preference, you can choose between a sheet-like window and a door glass window.
