The present subject matter described herein, relates to a mounting of a glass run with a window frame and, in particular, to structure of a glass run stopper and mounting of the glass run stopper with the window frame of a vehicle.
BACKGROUND AND PRIOR ART:
[002] In general, a window frame is formed by inner panel and outer panel. The window frame defines an open portion to receive a glass run. Fig. 1 illustrates general structure of window frame and an assembly of the glass run with the window frame. The window frame 100 includes an inner panel 102 and an outer panel 101. The inner panel 102 is joined with the outer panel 101. The inner panel
102 and the outer panel 101 define a wide open portion along transverse axis of
the vehicle to receive a glass run 104. The glass run 104 is joined with the inner
panel 102 and the outer panel 101 at both ends. Generally, the glass run 104 is in
fl shape or reverse U shape to receive upper edge of a door glass 105. The glass
run 104 is made of rubber or resin material. The glass run 104 has thin plate-like
bottom wall 104a facing the upper edge of the door glass 105 is formed integrally.
[003] Movement of the door glass 105 in the window frame 100 is stopped by bottom wall 104a of the glass run 104 and avoid direct hitting of the upper edge of the door glass 105 with the inner panel 102. Further the glass run 104 provides sealing between the door glass 105 and the window frame 100 to avoid entry of dust or water or air when window glass is closed. A gap 'LI' is provided in between the inner wall surface 102a of the inner panel 102 and the bottom wall 104a of the glass run 104. The gap 'LI' is necessary to be maintained to achieve proper height of the door glass 105. To maintain the gap 'LI', a glass run stopper
103 is interposed in between the inner wall surface 102a of the inner panel 102
and the bottom wall 104a of the glass run 104.
[004] Technical problem: the glass run stopper 103 is not fixedly assembled with the inner wall surface 102a of the inner panel 102, therefore longitudinal and vertical position of the glass run stopper 103 deviates from its original position

and there is possibility that the glass run stopper 103 do not stop the door glass 105 satisfactorily by maintaining the gap 'LI'. Another technical problem associated with the existing structure is pasting of the glass run stopper 103 (i.e. rubber stopper) is done manually and hence the position accuracy is low. This results in ineffective glass run mating with door window frame.
[005] In another means to maintain height of the door glass, referring to Fig. 2a, a stopper reinforcement bracket 203 is provided in between the glass run 204 and the inner panel 202. The stopper reinforcement bracket 203 is spot welded with the inner surface of the inner panel 202 as shown in Fig. 2a. In the arrangement as disclosed in Fig.2b, the glass run 204 act as rubber material between the stopper reinforcement bracket 203 and the door glass 205. The door glass 205 hits the glass run 204 against the stopper reinforcement bracket 203, therefore, the door glass 205 cut the glass run 204 and directly hits the stopper reinforcement bracket 203. Further, direct hitting of the door glass 205 against the stopper reinforcement bracket 203 creates sharp edges in the upper edge portion of the door glass 205 that are dangers for the occupants of the vehicle. Further, direct hitting of the door glass 205 with the stopper reinforcement bracket 203 damages the door glass 205 and creates unwanted noise.
[006] Another technical problem associated with above mentioned arrangement is undulations are introduced in weather-strip mounting surface due to the spot welds used for mounting of the stopper reinforcement bracket. This results in poor matching of weather-strip and door window frame and thus causing improper sealing. This in turn causes water leakage into the passenger cabin.
[007] Therefore, there is need in the art to provide a window frame structure that can maintain the gap between the glass run and the inner panel for door glass height adjustment and overcome the technical problem as mentioned above.
OBJECTS OF THE INVENTION:

view of mounted glass run stopper 303 with the inner panel 302 of window frame structure 300. The window frame structure 300 includes an inner panel 302 and an outer panel 301. The outer panel 303 joined with the inner panel 302 to define an open portion 300a in between the inner panel 302 and the outer panel 301. The inner panel 302 and the outer panel 303 are joined by any known method, such as press joining method. The open portion 300a is in channel shape to receive a glass run 304 that is also is in channel shape. The glass run 304 is provided in the open portion 300a to receive upper edge of a door glass 305. The glass run 304 defined a channel shape having a pair of sealing lip 304a, 304b in sliding contact with both sides and an upper wall 304c. The glass run 304 further includes a pair of outer lip 304d, 304e that are coupled with circumferential flange 302g of the inner panel 302 and with circumferential flange 301a of the outer panel 301. Further, coupling of the pair of outer lip 304d, 304e with the circumferential flange 302g, 301a of the inner and outer panel 302, 301 avoid falling of the glass run 304 from the open portion 300a of the window frame 300. The pair of sealing lip 302a, 304b receives the upper edge of glass door 305. The upper edge of the glass door 305 is stopped by the upper wall 304c of the glass run 304.
[0043] As shown in fig. 4, a gap 'L2' is defined in between the upper wall 304c of the glass run 304 and inner mounting wall 302c of the inner panel 302. A glass run stopper 303 is interposed in between the upper wall 304c of the glass run 304 and the inner mounting wall 302c of the inner panel 302 to fill the gap 'L2'. The glass run stopper 303 is mounted with the inner mounting wall 302c by a countersunk screw 306.
[0044] Referring to fig. 5 that illustrate cross section view along line CC of fig. 3. The inner panel 302 has a mounting hole 302b and a guiding hole 302a. The mounting hole 302b allow passage of the countersunk screw 306 from the inner panel 302 and mounting with the glass run stopper 303. Further, the guiding hole 302a guides or give direction for mounting of the glass run stopper 303 and receives guiding leg 405 (shown in fig. 6a) of the glass run stopper 303. The mounting hole 302b defines a countersink profile 302ba to receive head of the

countersunk screw 306 and leaves smooth upper surface. Similarly, the guiding hole 302a defines a countersink profile 302aa to receive the guiding leg 405 of the glass run stopper 303 and leaves smooth upper surface. The guiding hole 302a can be in shape of oblong hole or slot.
[0045] Referring to fig. 6a and 6b illustrating structure of the glass run stopper 303, 400. The glass run stopper 303, 400 may be defined in a cuboidal shape structure defining top surface, bottom surface, two longitudinal side surfaces joining the top surface and bottom surface along longitudinal direction (in lengthwise direction), and two transverse side surfaces provided in between the two longitudinal side surfaces joining the top surface and bottom surface along transverse direction (in widthwise direction). The glass run stopper 400 includes a mounting surface 401 and a receiving surface 402 that is opposite to the mounting surface 401. The glass run stopper 400 defines a longitudinal side surface 403 that joins the longitudinal edges of the mounting surface 401 and the receiving surface 402. The mounting surface 401 defines a first surface 401a and a second surface 401b joined by an edge portion 401c integrally. Further, the first surface 401a and the second surface 401b are differ in their height by height 'FT. The edge portion 401c may be chamfered portion or fillet portion or bevel portion. The edge portion 401c defines difference in height of the first surface 401a and the second surface 401b. The first surface 401a defines height 'HI' from the receiving surface 402 and the second surface 401b defines height 'H2' from the receiving surface 402. The height 'HI' is more than the height 'H2'.
[0046] Referring to fig. 6a, the glass run stopper 400 has a mounting hole 404 that is provided on the first surface 401a and a guiding leg 405 projected upwardly from the second surface 401b. The guiding leg 405 may be provided at edge portion of the second surface 401b which is opposite to the edge portion 401c. Referring back to fig. 5, the guiding leg 405 is provided at longitudinal distance 'L3' from the mounting hole 404. The glass run stopper 303, 400 is a cuboidal shape structure where height of the structure depends on the gap 'L2' between the glass run 304 and the inner mounting wall 302c. Further, the glass run stopper

303, 400 is made of rubber or resin material or ethylene propylene diene monomer rubber (EPDM) hard sponge material.
[0047] Referring Fig. 6b, the longitudinal side surface 403 extend beyond the receiving surface 402 to define legs 403a, 403b and transverse gap 'W which is more than width of the upper wall 304c of the glass run 304. The legs 403a, 403b define a channel shape to receive the upper wall 304c of the glass run 304 to avoid dis-assembly of the upper wall 304c with the glass run stopper 303 during use (or during hard slam of door).
[0048] Referring fig. 5 and 6a, the glass run stopper 400 has the mounting hole
404 of conical shape opening 404a (countersink profile) to receive head of the
countersunk screw 306 and a shaft bore 404b with internal threads to receive shaft
of the countersunk screw 306. Further, height '306a' of shaft of the countersunk
screw 306 is less than depth 404c of the shaft bore 404b so that shaft of the
countersunk screw 306 fits completely inside the shaft bore 404b.
[0049] Referring to fig. 5, the inner panel 302 includes a mounting hole 302b with a countersink profile 302ba to mount the glass run stopper 303, 400 with the countersunk screw 306 and a guiding hole 302a with a countersink profile 302aa to receive the guiding leg 405 of the glass run stopper 303, 400. The countersink profile 302ba allows complete mating of head of the countersunk screw 306 with the mounting hole 302b. Further, the countersink profile 302ba of the mounting hole 302b matches with the conical shape opening 404a of the head of the countersunk screw 306. Therefore, the countersink profile 402ba and conical shape opening of the glass run stopper 400 allow complete matching with the head of the countersunk screw 306 and leaves smooth surface on outer surface 302d of the inner panel 302. Further, the countersink profile 302aa of the guiding hole 302a of the inner panel 302 matches with raised profile of the guiding leg
405 of the glass run stopper 400 to leave smooth surface on the outer surface 302d
of the inner panel 302.

[0050] Referring back to fig. 5, the guiding hole 302a is provided at a longitudinal distance 'L4' from the mounting hole 302b. Further, the longitudinal distance 'L3' matches with longitudinal distance 'L4'.
[0051] In an aspect, as shown in fig. 5, the height of guiding leg 405 from the second surface 401b matches with difference of height between the first surface 401a and the second surface 401b.
[0052] Fig. 7 illustrate exploded view of mounting of glass run stopper 400 with the inner panel 302 of the window frame structure 300. The glass run stopper 303, 400 mounted on the inner panel 302 through the mounting hole 302b and the guiding hole 302a. Further, the upper surface 302d of the inner panel 302 remain smooth to have weather strip without any interference from the guiding leg and the countersunk screw.
[0053] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition,

even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
