Full Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a vehicle with a door which is capable of swinging horizontally.  
         [0003]     2. Description of the Related Art  
         [0004]     Conventionally, a door which swings horizontally to open and close is constructed such that two door hinges are mounted between the door and a vehicle body. The front edge of the door, on which the door hinges are mounted, is substantially vertical, so that the rotation centers of the upper and lower hinges correspond to each other. Also, as disclosed in Japanese Laid-Open Utility Model Publication No. 6-79617, there has been proposed a door which is constructed such that a double hinge is mounted on the front edge of the door to increase the angle at which the door can be swung.  
         [0005]     However, according to the above described arrangement in which two hinges are provided at upper and lower locations, if a vehicle has a door with such a special shape that the front edge thereof is not vertical, but is shaped like e.g., an arc, the rotation centers of the upper and lower hinges cannot be made to correspond to each other. Further, according to the arrangement disclosed in Japanese Laid-Open Utility Model Publication No. 6-79617, the weight of the door must be supported by a lower part thereof, and hence the hinge needs to be large and heavy.  
       SUMMARY OF THE INVENTION  
       [0006]     It is therefore an object of the present invention to provide a vehicle which is simply constructed, but can considerably increase the degree of freedom in designing a door capable of swinging horizontally.  
         [0007]     To attain the above object, there is provided a vehicle having a door capable of swinging horizontally to open and close via at least two hinges, in which door side hinge mounting parts are out of alignment in a direction of a length of a vehicle body, wherein at least one of the hinges comprises a vehicle body side hinge mounting part, a door side hinge mounting part, and an extension part connecting the vehicle body side hinge mounting part and the door side hinge mounting part to each other.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0012]     The present invention will now be described in detail with reference to FIGS.  1  to  3  showing an embodiment thereof.  
         [0013]     In FIGS.  1  to  3 , reference numeral  1  denotes a vehicle;  2 , a door (front door); and  3 , a wheel (front wheel).  
         [0014]     As shown in  FIG. 1 , the front door  2  of the vehicle  1  is inclined such that a front edge  4  thereof below a side window glass line projects toward the front of a vehicle body, and recedes toward the rear of the vehicle body as it goes downward. An upper hinge mounting part  6 , on which an upper hinge  5  is mounted, is provided in an upper part of the front edge  4  of the door  2 , while a lower hinge mounting part  8  on which an upper hinge  7  is mounted is provided in a lower part of the front edge  4  of the door  2 .  
         [0015]     As shown in  FIG. 1 , the front edge  4  of the door  2  is formed to recede toward the rear of the vehicle body as it goes downward, and hence the upper hinge mounting part  6  and the lower hinge mounting part  8  are significantly out of alignment in the direction of the length of vehicle.  
         [0016]     The upper hinge  5  is a gooseneck hinge which is projected and curved toward the inner side of the vehicle body, and prevents interference between the edge of the door  2  and the edge of the vehicle body when the door  2  is opened, and enables the door  2  to be opened at a large angle in such a way that the edge of the door  2  as well as the upper hinge  5  goes around the outer side of the edge of the vehicle body. The upper hinge  5  has one end thereof fixed to part of the vehicle  1  in front of and corresponding to the upper hinge mounting part  6 , and has the other end thereof fixed to part of the vehicle  1  in front of and corresponding to the upper hinge mounting part  6 , so that the door  2  can be pivotally supported on the vehicle  1  such that it may swing horizontally to open and close. It is to be noted that the upper hinge  5  may not necessarily be the gooseneck hinge as above, but may be either a single hinge or a double hinge insofar as it enables the door  2  to be opened and closed at a sufficient angle.  
         [0017]     As shown in  FIGS. 2 and 3 , the lower hinge  7  is comprised of a door side hinge mounting part  9  fixed to the lower hinge mounting part  8  of the door  2 , a vehicle body side hinge mounting part  10  fixed to part of the vehicle  1  in front of and corresponding to the lower hinge mounting part  8 , and an extension part  11  which is extended from the door side hinge mounting part  9  to be pivotally supported on the vehicle body side mounting part  10 . The extension part  11  is pivotally supported on the vehicle body side hinge mounting part  10  at the front of the vehicle so that the rotation centers of the extension part  11  and the upper hinge  5  can correspond to each other. The door  2  is pivotally supported on the vehicle  2  by the upper hinge  5  and the lower hinge  7  such that the door  2  may swing horizontally to open and close.  
         [0018]     Further, a cover  12  which covers the extension part  11  of the lower hinge  7  to form a surface substantially flush with the vehicle body with the door  2  being closed as shown in  FIG. 1  is provided on the side of the lower part of the vehicle body. In the lower part of the inner side of the vehicle body, the cover  12  is pivotally supported on the vehicle body by a hinge  13  so that the cover  12  can spread out to the outside of the vehicle body. It should be noted that the hinge  13 , which pivotally supports the cover  12 , is forced in such a direction as to be flush with the outer side of the vehicle body.  
         [0019]     When the door  2  is opened, the extension part  11  of the lower hinge  7  pushes the cover  12  to the outside of the vehicle body so that the cover  12  can spread out to the outside of the vehicle body, and hence the extension part  11  never interferes with the vehicle body. When the opened door  2  is closed, the cover  12  which has spread out to the outside of the vehicle body moves in such a direction as to be flush with the external side of the vehicle body, so that the cover  12  can be flush with the outer side of the vehicle body with the door  2  being closed.  
         [0020]     Therefore, even in the door  2 , which is constructed such that the front edge  4  thereof recedes toward the rear of the vehicle body as it goes downward, and the upper hinge mounting part  6  and the lower hinge mounting part  8  as shown in  FIG. 1 , are significantly out of alignment, the rotation centers of the upper hinge  5  and the lower hinge  7  can be made to correspond to each other by a simple construction in which the lower hinge  7  is provided with the extension part  11 , so that the door  2  can swing horizontally to open and close. Further, the provision of the cover  12 , which covers the extension part  11 , improves the appearance when the door  2  is closed, and prevents the extension part  11  from interfering with the side of the vehicle body when the door  2  is opened. Further, the provision of the cover  12  considerably increases the degree of freedom in designing the shape of the door  2 .  
         [0021]     Although in the above-described embodiment, the present invention is applied to the door  2  shaped as illustrated in  FIG. 1 , but the present invention may be applied to doors with various shapes, such as a door whose front edge is inclined to recede toward the rear of a vehicle body as it goes downward. If the present invention is applied to such a door, an upper hinge provided with an extension part as described above is mounted on the front edge of the door, and a cover for the upper hinge is provided so that the door can be swung horizontally to open and close by a simple construction without degrading the appearance.  
         [0022]     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
