Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a method for attaching door parts and unified parts used in the method, where the door parts including a door glass, quarter glass and a division bar are attached to an automobile door equipped with a door glass (rear glass or front glass) and a quarter glass (a triangular-shaped glass). 
     2. Description of the Prior Art 
     Conventionally, as shown in FIG. 8, in an automobile door equipped with a door glass (rear glass or front glass)  7  and a quarter glass  4 , a division bar  2  is installed between the door glass  7  and the quarter glass  4  subsequent to an attachment of a glass run  6  to one side of the division bar  2 . This is because if the division bar  2  is installed prior to the quarter glass  4 , the quarter glass  4  cannot be installed. 
     That is, the conventional method for attaching the door parts is such that, at first, the quarter glass  4  (comprised with a glass seal around its periphery) is installed. Then, the glass run  6  is attached from the center pillar side toward the roof side of an automobile. Subsequently, after attaching the glass run  6  to one side of the division bar  2 , the division bar  2  is attached to the quarter glass  4 . Finally, the roof side of the glass run  6  is attached. 
     However, the conventional method required skill and time and had poor workability of installation, since the division bar  2  needed to be inserted in the narrow gap between the quarter glass  4  and the door glass  7  from the top and needed to be installed to the door panel  8 . Further, at the time of the installation, the tip of the division bar  2  contacted the door panel  8 , thereby damaging the paint of the door panel  8 , which became a cause of degraded appearance and the generation of rust. 
     Furthermore, the glass run  6  needed to be attached to one side of the division bar  2  in advance. In this installation process, both the glass run  6  and the division bar  2  were in a free position, therefore there was difficulty in completing the process. This was another drawback concerning the workability of installation. Moreover, since the glass run  6  and the glass seal  5  were individual moldings, there developed a level difference  13  between both parts, causing a degraded appearance. 
     Japanese patent publication No. 7-5025 discloses a structure in FIG.  4 ( c ), where the vent assembly body ( 5 ) equipped with the division bar ( 1 ) is attached to the door (D). However, in this structure, there is no member which carries out temporary support of the front end of the door glass ( 3 ) at the time of installation of the door glass ( 3 ). And, there still remains the problem that a level difference is developed, degrading an appearance of the door and an automobile. 
     Therefore, an object of this invention is to provide a method for attaching door parts of an automobile door which has excellent workability of installation and which enables the door parts to be attached without damaging the paint of a door frame. Another object of this invention is to provide unified parts of an automobile door which are excellent in installation workability and which do not damage the paint of a door frame. 
     SUMMARY OF THE INVENTION 
     In order to attain the above-mentioned object, there is provided a first aspect of the invention which provides a method for attaching door parts of an automobile door equipped with a door glass ( 7 ) and a quarter glass ( 4 ), which comprises the following steps. A lower-bar ( 2   b ) of a division bar ( 2 ) is attached inside a door panel ( 8 ). The division bar ( 2 ) comprises the lower-bar ( 2   b ) and an upper-bar ( 2   a ) which is separated from and positioned above the lower-bar ( 2   b ) and is installed between the door glass ( 7 ) and the quarter glass ( 4 ). A glass seal ( 5 ) of unified parts ( 1 ) is attached to the periphery of a quarter glass ( 4 ), forming a quarter part ( 3 ). The unified parts ( 1 ) is formed by integrally molding the upper-bar ( 2   a ) made of resin, a glass seal ( 5 ) and a glass run ( 6 ) for sealing the door glass ( 7 ).

     A second aspect of the invention provides unified parts ( 1 ) of an automobile door equipped with a door glass ( 7 ) and a quarter glass ( 4 ). A division bar ( 2 ) made of resin consists of an upper-bar ( 2   a ) and a lower bar separately positioned up and down. The upper-bar ( 2   a ) is installed between the door glass ( 7 ) and the quarter glass ( 4 ), and the lower-bar ( 2   b ) is attached inside a door panel ( 8 ). The upper-bar ( 2   a ) is integrally molded with a glass seal ( 5 ) for sealing the quarter glass ( 4 ) and a glass run ( 6 ) for sealing the door glass ( 7 ). A quarter part ( 3 ) is formed by attaching the glass seal ( 5 ) to the periphery of the quarter glass ( 4 ). The center pillar side of the glass run ( 6 ) is attached to a door frame ( 9 ) subsequent to an attachment of the lower bar. The bottom end of the upper-bar ( 2   a ) is connected to the top end of the lower-bar ( 2   b ), after the door glass ( 7 ) is attached with a support of the lower-bar ( 2   b ). And, the quarter part ( 3 ) and the remaining portion of the glass run ( 6 ) is attached to the corresponding portions, respectively. 
     A third aspect of the invention which provides unified parts ( 1 ) of an automobile door equipped with a door glass ( 7 ) and a quarter glass ( 4 ). A division bar ( 2 ) made of resin consists of an upper-bar ( 2   a ) and a lower bar separately positioned up and down. The upper-bar ( 2   a ) is installed between the door glass ( 7 ) and the quarter glass ( 4 ). The lower-bar ( 2   b ) is installed inside a door panel ( 8 ). The upper-bar ( 2   a ) is integrally molded with a glass seal ( 5 ) for the quarter glass ( 4 ). A glass run ( 6 ) for the door glass ( 7 ) is connected to the unified upper-bar ( 2   a ) and the glass seal ( 5 ) with a hook ( 11 ,  12 ) from the inside or outside the automobile. A quarter part ( 3 ) is formed by attaching the glass seal ( 5 ) to the periphery of the quarter glass ( 4 ). The center pillar side of the glass run ( 6 ) is attached to a door frame ( 9 ) subsequent to an attachment of the lower bar. The bottom end of the upper-bar ( 2   a ) is connected to the top end of the lower-bar ( 2   b ) after the door glass ( 7 ) is attached with a support of the lower-bar ( 2   b ). And, the quarter part ( 3 ) and the remaining portion of the glass run ( 6 ) is attached to the corresponding positions, respectively. 
     A fourth aspect of the invention provides unified parts ( 1 ) of an automobile door, wherein the glass run ( 6 ) is integrally molded with the upper-bar ( 2   a ) in the third aspect of the invention. 
     A fifth aspect of the invention provides unified parts ( 1 ) of an automobile door, wherein the outside or the inside of the hook ( 11 ,  12 ) is decorated in the third or the fourth aspect of the invention. 
     As used herein, door glass includes both a rear glass and a front glass, and quarter glass refers to a triangular-shaped glass attached in a vent. The numerals in parentheses indicate the corresponding elements or corresponding matters indicated in the drawings and the below described preferred example of the invention. 
     According to the first aspect of the invention (a method for attaching door parts of an automobile door), the door parts are installed in the following manner: the lower-bar of the division bar is installed; the glass seal among the unified parts is attached to the quarter glass; the center pillar side of the glass run is attached to the door frame; the door glass is attached; the bottom end of the upper-bar is connected to the top end of the lower-bar; and the quarter part and the remaining portion of the glass run is attached. Therefore, unlike as in the prior art, it is not necessary to insert the division bar in the narrow gap between the door glass and the quarter glass. 
     Thus, it is easy to attach the door parts to an automobile door without skill, so that the workability of installation improves. Further, during the installation process, such incident can be avoided that the tip end of the division bar makes contact with the door panel damaging the paint thereof. Therefore, degradation of appearance and development of rust can be prevented. Furthermore, the door glass is attached subsequent to the attachment of the lower-bar of the division bar, so that a temporary support of the door glass can be carried out with the lower bar. Therefore, it is not necessary to manually hold the door glass during the installation, so that the workability of installation improves. 
     Moreover, the upper-bar and the glass seal are integrally molded, so that it can prevent a development of a level difference between both parts, and the appearance of the door improves. Further, since the parts are attached collectively, the installation process can be attained with less man-hours. 
     According to a second aspect of the invention (unified parts of an automobile door), the unified parts comprise a division bar made of resin consisting of an upper-bar and a lower bar separately positioned up and down. The upper-bar is installed between the door glass and the quarter glass, whereas the lower-bar is attached inside the door panel. The upper-bar is integrally molded with a glass seal for the quarter glass and a glass run for the door glass. The quarter part is formed by attaching the glass seal to the periphery of the quarter glass. The center pillar side of the glass run is attached to the door frame subsequent to an attachment of the lower bar. The bottom end of the upper-bar is connected to the top end of the lower-bar, after the door glass is attached with a support of the lower-bar. The quarter part and the remaining portion of the glass run is attached to the corresponding portions. 
     Therefore, it is easy to attach the door parts including the unified parts to an automobile door, so that the workability of installation improves. Further, at the time of the installation process, such incident can be avoided that the tip end of the division bar makes contact with the door panel, thereby damaging the paint thereof. 
     Moreover, the unified parts are structured integrally composing the upper-bar, the quarter part (a combination of the quarter glass and the glass seal) and the glass run, so that they can be handled as one part, and so that man-hours of installation can be lessened. 
     According to a third aspect of the invention the glass run is connected to the integrally molded parts of the upper-bar and the glass seal, so that various ornaments can be provided to both inside and outside of an automobile. 
     According to the fourth aspect of the invention, the glass run is integrally molded with the upper end of the upper-bar, so that it can prevent development of a level difference between both parts.

     DESCRIPTION OF PREFERRED EMBODIMENT 
     A preferred embodiment of a method for attaching door parts according to the present invention will be described hereinafter, referring to FIGS. 1 to  3 . 
     FIG. 1 is an elevation view showing a door where unified parts of an automobile door according to the present invention are attached. FIG. 2 is a perspective view showing the principal part of the unified parts of an automobile door according to the present invention. FIG. 3 is an enlarged vertical view along line A—A in FIG.  2 . Although the quarter part  3  shown in FIG. 2 is somewhat dissimilar in shape from the one shown in FIG. 1, the fundamental compositions are identical. The identical numerals are given to parts similar to ones in the conventional example. 
     A preferred embodiment of unified parts of automobile door  1  according to the present invention is installed to a door of an automobile equipped with a door glass (rear glass)  7  and a quarter glass  4 . The unified parts  1  comprise a division bar  2 . The division bar  2  is divided into an upper-bar  2   a  and a lower-bar  2   b , and the upper-bar  2   a  is installed between a door glass  7  and a quarter glass  4 , whereas the lower-bar  2   b  is attached inside a door panel  8 . At least the upper-bar  2   a  is made of resin (and the lower-bar  2   b  can also be made with resin). The upper-bar  2   a  is integrally molded in advance with a glass seal  5  which is attached to the entire periphery of a quarter glass  4 . Further, as shown in FIG. 4, a glass run  6  for receiving a door glass  7  is attached to the integrally molded parts with a hook  11 . The quarter glass  4  is inserted in the groove  5   a  formed in the glass seal  5 . 
     Further, the glass run  6  is also integrally molded with the top end  2   t  of the upper-bar  2   a  to which the glass seal  5  is integrally molded, thereby preventing a development of a level difference between the upper-bar  2   a  and the glass run  6 . 
     The hook  11  is provided with a hook-shaped convex  11   a  at the outside thereof, and is also provided with a bulge  11   b  at the end of the glass run side (the right-hand side in FIG.  4 ). When the glass run  6  is attached to the unified structure of the upper-bar  2   a  and the glass seal  5 , the convex  11   a  fits into a concave  2   p  formed in the upper-bar  2   a , while the bulge lib is caught by a projection  6   a  formed at the side wall of the glass run  6 . 
     Further, at the inner side of the hook  11 , there is provided a decoration with color material, cloth, feathering and the like, which is harmonized with the interior of the automobile, making a great-looking layout. 
     The hook  11  is not limited in its shape like the one shown in FIG. 4, and such a hook  12  having about a L-shaped form in section may be used. When the glass run  6  is attached to the hook  12 , the L-shaped end  12   a  thereof fits into a concave  5 B formed inner side of the glass seal  5 , while the bulge  12   b  engages with the projection  6   a  formed at the side wall of the glass run  6 . 
     The unified parts of an automobile door comprise a quarter part  3  which is formed by attaching the glass seal  5  to the periphery of a quarter glass  4 . In such structure, the center pillar side of the glass run  6  is attached to the door frame  9  subsequent to an installation of the lower-bar. The door glass  7  is attached with a support of the lower-bar  2   b , then the bottom end of the upper-bar  2   a  is connected to the top end of the lower-bar  2   b , subsequently, the quarter part  3  is attached to the door frame  9 , and the rest portion of the glass run  6  is attached to the roof side of the automobile. 
     Through use of the unified parts  1  according to the preferred embodiment, it is not necessary to insert the division bar  2  into the narrow gap formed between the door glass  7  and the quarter glass  4 , so that the workability of installation improves. Further, such incident can be avoided that the tip of the division bar  2  makes contact with the door panel  8 , thereby damaging the paint thereof at the time of installation. 
     Furthermore, since the upper-bar  2   a  is integrally molded with the glass seal  5 , there is provided no level difference between both parts, thereby making a great-looking layout. Moreover, integrally formed parts can be easily manufactured, therefore, number of parts can be decreased. 
     Referring to FIG. 6, a method for attaching door parts of an automobile door with above-mentioned unified parts will be described hereinafter. The automobile is equipped with a door glass (rear glass)  7  for a rear door and a triangular-shaped quarter glass  4  for a vent window. 
     In this method, first of all, the lower-bar  2   b  of the division bar  2  is installed to the door panel  8  (see FIG.  6 ( a )). The division bar  2  is composed of the upper-bar  2   a  and the lower-bar  2   b , which are separately formed and are positioned up and down. The upper-bar  2   a  is to be installed between the door glass  7  and the quarter glass  4 , and the lower-bar is to be installed to the door panel  8 . 
     Then, the upper-bar  2   a , which is made of resin and is integrally molded with a glass seal  5 , is attached to a glass run  6  with a hook  11  or  12 . Subsequently, the glass seal  5  is attached to the periphery of the quarter glass  4 , forming a quarter part  3 . Then, the center pillar side of the glass run  6  (the left-hand side in FIG. 6) is attached to the door frame  9 . 
     Subsequently, the door glass  7  is installed. In this process, the center pillar side edge of the door glass  7  (the left-hand side in FIG. 6) is supported by the door frame  9  as it is inserted in the door frame  9 , while the opposite side of the door glass  7  (the right-hand side in FIG. 6) is supported by the lower-bar  2   b  as it is inserted in the lower-bar  2   b . 
     Finally, the bottom end of the upper-bar  2   a  is connected to the top end of the lower-bar  2   b , and the quarter part  3  is rotated in the direction illustrated with the arrow in order to secure to the door frame  9 , then, the remaining portion of the glass run  6  is attached to the roof side of the automobile (see FIG. 6 ( b )). 
     Although, in the above-mentioned method, the quarter part  3  is attached to the door frame  9  with a rotational movement, the quarter part  3  can be attached without such movement if, as shown in FIG. 7, the hook  11  or  12  is applied instead. Further, by using the hook  11  or  12 , it is easy to attach a smaller size of quarter part  3 , which is usually difficult to install. 
     A method of attachment using the hook  11  or  12  will be described below referring to FIG. 7 ( a ). First, the lower-bar  2   b  is installed to the door panel  8 . Then, the glass seal  5 , which is integrally molded with the upper-bar  2   a  with or without the glass run  6 , is attached to the periphery of the quarter glass  4 , forming a quarter part  3 . Subsequently, the center pillar side of the glass run (the left-hand side in FIG. 7) is attached to the door frame  9 . 
     Then, the door glass  7  is installed. In this process, the center pillar side edge of the door glass  7  (the left-hand side in FIG. 6) is supported by the door frame  9  as it is inserted in the door frame  9 , while the opposite side of the door glass  7  (the right-hand side in FIG. 6) is supported by the lower-bar  2   b  as it is inserted in the lower-bar  2   b.    
     Subsequently, as shown in FIG.  7 ( b ), after positioning the bottom end of the upper-bar  2   a  over the top end of the lower-bar  2   b , the quarter part  3  is slid in the horizontal direction, thereby attaching the quarter part  3  to the door frame  9 . Then, the remaining portion of the glass run  6  is attached to the roof side of the automobile. And, finally, the hook  11  or  12  is applied as shown in FIG.  7 ( c ). 
     According to the method described above, it is not necessary to insert the division bar  2  into the narrow gap provided between the door glass  7  and the quarter glass  4 , so that an attachment of the door parts can be easily attained. 
     Further, such incident can be avoided that while the division bar  2  is installed, the tip thereof makes contact with the door panel  8 , thereby damaging the paint of the panel  8 . Therefore, degradation of appearance and development of rust can be prevented. Furthermore, the door glass  7  can be temporarily supported by the lower-bar  2   b , so that it is not necessary to manually hold the door glass  7  during the installation operation, and the workability of installation improves. Moreover, since the upper-bar  2   a  and the glass seal  5  are integrally molded, a level difference  13  does not appear between both parts  2   a ,  5 , unlike the conventional example (FIG.  8 ). Thus, an outlook of the door and the automobile improves. 
     The above-described embodiment comprises such structure that the glass run  6  is connected to the integrally molded upper-bar  2   a  and the glass seal  5  with the hook  11  or  12 . Instead of such structure, the three parts, the upper-bar  2   a , the glass seal  5  and the glass run  6  can be integrally molded. 
     Further, the hook  11  or  12  in the embodiment is illustrated and explained only in the case it is attached from inside the automobile, but it may be such a structure that it is attached from outside the automobile (illustration abbreviated). 
     Furthermore, although the door glass  7  is explained with respect to the case of a rear glass, this invention can be applied to a door where a front glass and a quarter glass are equipped adjacently. 
     According to the method of the present invention for attaching door parts of an automobile door, unlike as in the conventional art, it is not necessary to insert a division bar into a narrow gap formed between a door glass and a quarter glass. 
     Therefore, it is easy to attach the door parts to an automobile door without skill, so that the workability of installation improves. Further, during an attachment process, such incident can be avoided that the tip end of a division bar makes contact with a door panel, thereby damaging the paint thereof. Therefore, degradation of appearance and development of rust can be prevented. Furthermore, a door glass is installed subsequent to an attachment of the lower-bar of a division bar, so that the door glass can be temporarily supported by the lower bar during the installation. Therefore, it is not necessary to manually hold the door glass, and the workability of installation improves. 
     Moreover, the upper-bar and a glass seal are integrally molded, so that a development of a level difference between both parts can be prevented, and that an appearance of the door improves. Further, since parts are installed collectively, an attachment process can be attained with less man-hours. 
     According to the unified parts of the present invention, it is not necessary to insert a division bar into a narrow gap created between a door glass and a quarter glass. Therefore, it is easy to attach door parts including unified parts to an automobile door, so that the workability of installation improves. Further, at the time of an attachment process, such incident can be avoided that the tip end of a division bar makes a contact with a door panel, thereby damaging the paint thereof. 
     Moreover, the unified parts of the present invention are structured integrally, and comprise an upper-bar, a quarter part (a combination of a quarter glass and a glass seal) and a glass run, so that it can be handled as one part, so that man-hours of installation can be reduced. 
     Also according to the present invention, a glass run is connected to a integrally molded parts of an upper-bar and a glass seal, so that various ornaments can be provided both inside and outside of an automobile. 
     And also according to the present invention, a glass run is integrally molded with the upper end of an upper-bar, so that it can prevent development of a level difference between both parts.
