DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0031] Hereinafter, a glass run of a door for a vehicle according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0032] According to the present disclosure, the glass run may be mounted on a door 10 for a vehicle (not shown) to support a door glass 30, in which a core 22 may be inserted into the glass run 21. The core 22 may include a flat portion 22a formed to extend to a predetermined height in a longitudinal direction of the core 22 and a punched portion 22b extended in a direction perpendicular to the longitudinal direction of the core 22 from the flat portion 22a.

[0033] The glass run 21 may be made of synthetic rubber, formed to have a predetermined cross-sectional shape, and may be mounted on the door panel 11.

[0034] An upper fixing portion 21a and a lower fixing portion 21b coupled to the door panel 11 are respectively formed on an upper portion and a lower portion of the glass run 21. A portion of the door panel 11 may be inserted into each of the upper fixing portion 21a and the lower fixing portion 21b so that the glass run 21 may be mounted on the door panel 11.

[0035] A sealing portion 21c in contact with an end portion of the door glass 30 to seal a portion between the door panel 11 and the door glass 30 may be formed between the upper fixing portion 21a and the lower fixing portion 21b. The sealing portion 21c may be formed to protrude from the glass run 21 and may have an end portion in contact with the door glass 30 to be sealed. A plurality of sealing portions 21c are formed at intervals and formed to be in contact with each of both side surfaces of the door glass 30.

[0036] The core 22 for providing a predetermined stiffness to prevent the glass run 21 from being separated from the door panel 11 in a state of being coupled to the door panel 11 may be inserted into the glass run 21.

[0037] The core 22 may allow the glass run 21 to provide the predetermined stiffness in a state of being inserted into the upper fixing portion 21a.

[0038] The core 22 may include a flat portion 22a and a plurality of punched portions 22b extending from each of an upper end and a lower end of the flat portion 22a.

[0039] The flat portion 22a may have a predetermined height and may be formed in the longitudinal direction of the core 22. Therefore, the flat portion 22a may have a belt shape.

[0040] Each of the punched portions 22b may be formed to extend in a direction perpendicular to the longitudinal direction of the core 22 from an upper end and a lower end of the flat portion 22a. Each of the punched portions 22b may be repeatedly formed in the longitudinal direction of the core 22, and a gap22c may be formed between adjacent punched portions 22b. In other words, each of the punched portions 22b may be repeatedly formed at the predetermined gap 22c in the longitudinal direction of the core 22.

[0041] The plurality of punched portions 22b may extend from each of the upper end and the lower end of the flat portion 22a and may have a shape bent from the flat portion 22a. In addition, each of the punched portion 22b may be manufactured by a punching process of one large flat plate member with the gap 22c and then by bending each of the punched portion 22b from the upper end and the lower end of the flat portion 22a.

[0042] Since the core 22 has the plurality of punched portions 22b bent from each of the upper end and the lower end of the flat portion 22a, the glass run 21 may be easily deformed as following an upper line of the door 10. Therefore, the glass run 21 may be applied to the door 10 even when the upper line of the door 10 changes rapidly.

[0043] For example, conventionally, the radius R1 of the upper line needs to be 600 mm or more, but since a radius R2 of the upper line of the door 10 in the present disclosure may be 50 mm or more, the upper line of the door 10 may be designed even in a rapidly changed shape and manufactured without increasing the production cost.

[0044] The glass run 21 may be made of synthetic rubber such as ethyl propyl diene monomer (EPDM).

[0045] In particular, a portion of the glass run 21 exposed to the outside may be finished as it is without a finishing member such as the frame molding 123 in the related art. Therefore, a portion in which the frame molding 123 of the related art has been exposed to the outside may become a finishing portion 21d formed to have a flat surface as shown in FIG. 7.

[0046] Unlike the conventional frame molding 123 which has been additionally mounted on the glass run 121, the finishing portion 21d may be simultaneously formed when the glass run 21 is manufactured, so the number of processes may be reduced.

[0047] In particular, the finishing portion 21d may have a flat shape when exposed to the outside, which may be supported by the flat portion 22a of the core 22 inserted into the glass run 21. In other words, an imaginary surface projected from the flat portion 22a to a surface of the glass run 21 may become the finishing portion 21d which is exposed to the outside in a state when the glass run 21 is assembled to the door panel 11.

[0048] Here, since the finishing portion 21d may be exposed to the outside as it is, the surface of the finishing portion 21d may be coated with silicone 23b so that a gloss of the finishing portion 21d may be reduced and a different color and a different feeling from components mounted around the finishing portion 21d may be improved. Since the components mounted around the finishing portion 21d, such as a quarter garnish, may be made of polyvinyl chloride (PVC) or thermoplastic vulcanizates (TPV). When the glass run 21 is made of EPDM, the finishing portion 21d may cause the different feeling, and colors are not matched with each other. Therefore, by coating the finishing portion 21d with the silicone 23b, the same gloss and color as the PVC material may be implemented.

[0049] The sealing portion 21c of the glass run 21 may be coated with urethane 23a for waterproofing.

[0050] While this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications and combinations of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to the description. It is therefore intended that the appended claims encompass any such modifications or embodiments.
