BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates to a door frame for a vehicle. More particularly, the present invention relates to a door frame for a vehicle coupled with a bright molding.
2. Description of Related Art
Generally, a door frame for a vehicle is a window frame which is attached to a door of a vehicle. That is, a door frame for a vehicle is a frame which is formed so as to defend and cover a door glass. Further, a door glass run is mounted to a door frame for a vehicle so as to guide for opening/closing a door glass.
a door frame for a vehicle may be coupled with a bright molding. Herein, the bright molding is a portion which is exposed to exterior, and is mounted to outside of a door frame for a vehicle. In addition, the bright molding may be produced by various designs for improving the aesthetic features of a vehicle.
Conventionally, it is not easy for a shape of a door frame for a vehicle to be changed according to a shape of the bright molding. In addition, additional constituent elements are required for coupling the bright molding formed in various shapes in the state of not changing a shape of a door frame for a vehicle. For example, a plastic member is disposed between a door frame for a vehicle and the bright molding such that it is possible to couple a door frame for a vehicle with the bright molding. Further, the bright molding can be coupled with a door frame for a vehicle by using a member such as a rivet.
However, engagement composition for coupling a door frame for a vehicle with the bright molding is complex and the production cost is increased if the additional constituent elements are used. In addition, weight of the door frame that the bright molding coupled therewith is increased. Meanwhile, even if the additional constituent elements are used, strong coupling of a door frame for a vehicle and the bright molding of which shapes are different from each other is limited.
The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

In addition, the extending portion 114 forms the door frame 10 as one surface of the extending portion 114 contacts one surface of the glass run contact portion 106. Herein, the one surface of the extending portion 114 will be called “outer frame contacting surface 115”, and the one surface of the glass run contact portion 106 will be called “inner frame contacting surface 105”. Meanwhile, the extending portion 114 may be formed in various shapes such that the door weather strip 30 may be easily mounted at a part of the extending portion 114.
The door glass run 34 includes a glass run frame 32. The glass run frame 32 is disposed in the inside of the door glass run 34 for maintaining a shape of the door glass run 34. In addition, a part of the glass run frame 32 is formed in a shape of “U”, and the inner frame contacting surface 105 and the outer frame contacting surface 115 are disposed inside of the “U” shape of the glass run frame 32. Further, the part of glass run frame 32 formed with the “U” shape is provided to pressurize the door glass run 34 for gripping the inner frame contacting surface 105 and the outer frame contacting surface 115. Thus, the door glass run 34 is mounted on the door frame 10.
The bright molding 20 includes a frame contact portion 21, a first bending portion 22, a first blocker 23, a second bending portion 25, and a second blocker 26.
The frame contact portion 21 is a portion which is contacted to the one surface of the molding mounting portion 102 of the outer frame 100. In addition, the frame contact portion 21 has a uniform width so as to be surface-contacted with the molding mounting portion 102.
The first bending portion 22 is bent and extended from one end of the frame contact portion 21 toward an internal direction of vehicle. In addition, the first bending portion 22 is formed to surround the one end of the molding mounting portion 102 and a part of the hemming portion 104.

The bright molding 20 is prevented from escaping from the outer frame 100 as one end of the molding mounting portion 102 where the hemming portion 104 is formed is blocked by the first blocker 23.
The second bending 25 is extended in a shape of “U” from the other end of the frame contact portion 21, and then is bent and extended toward an internal direction of vehicle. In addition, the second bending 25 bent toward an internal direction of vehicle is inserted into the mounting hole 108 of the outer frame 100. That is, if a portion which is connected with the other end of the frame contact portion 21 is one end of the second bending 25, the other end of the second bending 25 is bent in a shape of “U” and is then bent and extended toward an internal direction of vehicle.
The second blocker 26 is formed at the second bending portion 25 so as to hook one side surface of the mounting hole 108. In addition, the second blocker 26 hooks the mounting hole 108 such that the bright molding 20 is prevented from escaping from the outer frame 100.
As described above, the door glass run 34 is mounted on the inner frame contacting surface 105 and the outer frame contacting surface 115. In addition, the inner frame contacting surface 105 and the outer frame contacting surface 115 are formed in shapes which are formed for easily mounting the door glass run 34. Further, an additional shape of the glass run contact portion 106 for mounting the door glass run 34 and preventing the door glass 3 from escaping is not required according to the door glass run 34 being mounted to the inner frame contacting surface 105 and the outer frame contacting surface 115, and the other part of the glass run frame 32 being formed in a shape of “U” so as to prevent that the door glass 3 escapes. Thus, the shape of the outer frame 100 can be simple. Herein, the glass run frame 32 is formed in a shape of ‘S’ made by the two ‘U’.
Meanwhile, in some embodiments, the bright molding 20, the outer frame 100, and the inner frame 110 may be formed by roll forming. Herein, the roll forming is a method which is often used when a plate or a frame bent in a complex shape is manufactured, and the method is known in the art such that a detailed description thereof will be omitted.
The bright molding 20 further includes a plastic portion 40. The plastic portion 40 is integrally formed with the bright molding 20 by injection molding after the bright molding 20 is formed by roll forming. The plastic portion 40 is injected to entirely or substantially entirely surround the bright molding 20 and then is cut as necessary. Further, the plastic portion 40 is formed of a plastic material having elastic force. That is, the plastic portion 40 may be formed of a material such as rubber.
The plastic portion 40 is separated to a first plastic portion 42 and a second plastic portion 44 by cutting. The first plastic portion 42 surrounds the first bending portion 22 and the first blocker 23 of the bright molding 20. In addition, the first plastic portion 42 further surrounds a part of the frame contact portion 21 connected with the first bending portion 22. Further, the first plastic portion 42 functions such that the molding mounting portion 102 smoothly passes the first blocker 23 and is easily positioned at the first bending portion 22 when the bright molding 20 is mounted at the outer frame 100.
The first plastic portion 42 forms a skin lip 46. The skin lip 46 is protruded toward the vehicle body 2 closed by the door and contacts the vehicle body 2. In addition, the skin lip 46 is exposed to the outside of the vehicle between the bright molding 20 and the vehicle body 2. Furthermore, it is possible to remove a lip which is required to be formed at the door weather strip 3 and extended to between the bright molding 20 and the vehicle body 2 according to the skin lip 46 being formed at the first plastic portion 42. Therefore, a shape of the door weather strip 30 can be simple.
The second plastic portion 44 surrounds the second bending 25 and the second blocker 26 of the bright molding 20. In addition, the second plastic portion 44 further surrounds a part of the frame contact portion 21 which is connected with the second bending portion 25. Further, the second plastic portion 44 functions such that the mounting hole 108 is smoothly positioned to the second bending portion 25 passing through the second blocker 26 when the bright molding 20 is mounted to the outer frame 100.
An amount of the first plastic portion 42 and the second plastic portion 44 surrounding the frame contact portion 21 is regulated by regulating an amount of cutting the plastic portion 40 between the first plastic portion 42 and the second plastic portion 44. That is, the width S of the bright molding 20 which is exposed is regulated according to an amount of cutting the plastic portion 40.
In some embodiments, the bright molding 20 may be formed of an SUS material, and the plastic portion 40 may be formed of a PVC material. Colors of the bright molding 20 and the plastic portion 40 may be predetermined considering the aesthetic features.
