Abstract

PROBLEM TO BE SOLVED: To provide a vehicular glass run capable of suppressing collision noise when a door glass abuts on an upper edge part of the glass run, even if the door glass ascends while tilting in a vehicle fore-and-aft direction.SOLUTION: A mold base portion 61 is formed so as to be thinner than an extrusion base portion 51, and a mold abutting portion 62 is projected out higher than an extrusion abutting portion 52. Therefore, an outer peripheral surface of the mold base portion 61 has an interval from an inner peripheral surface of an upper edge portion of a door sash which is larger than an interval from an outer peripheral surface of the extrusion base portion 51. An inner peripheral surface of the mold base portion 61 has height similar to the height of an inner peripheral surface of an extrusion lip 51a in a state in which the extrusion lip 51a is pressed from a lower side to abut on an inner peripheral surface of the extrusion base portion 51.

Description

本発明は、車両のドアサッシュに取り付けられ、ドアガラスとドアサッシュとの隙間をシールする車両用ガラスランに関するものである。   The present invention relates to a glass run for a vehicle that is attached to a door sash of a vehicle and seals a gap between the door glass and the door sash.

従来、車両のドアサッシュの内側周縁にドアガラスの昇降を案内するガラスランを設け、このガラスランによってドアガラスとサッシュとの隙間をシールしている。   Conventionally, a glass run for guiding the raising and lowering of the door glass is provided on the inner periphery of the door sash of the vehicle, and the gap between the door glass and the sash is sealed by this glass run.

このような構造において開放されているドアガラスを閉じる場合、ドアガラスをガラスランの上縁部分に当接するまで上昇させるが、このとき、ドアガラスの上辺がガラスランに当接するときの音が発生する。この音は、ドアガラスに突き上げられたガラスランの外周面がドアサッシュの内側に衝突することにより発生するものであり、この衝突音を低下させるための様々な工夫が行われている。   When closing the open door glass in such a structure, the door glass is raised until it contacts the upper edge of the glass run, but at this time, a sound is generated when the upper side of the door glass contacts the glass run. To do. This sound is generated when the outer peripheral surface of the glass run pushed up to the door glass collides with the inside of the door sash, and various devices have been made to reduce the collision sound.

例えば、特許文献１には、直線部とコーナー部とからなるガラスランであって、ガラスランの直線部の底壁の外周面とドアフレームとの間隔を大きくすることにより、ドアガラスが上昇してガラスランの底壁を押したときに底壁中央部が充分に撓むことができ、ドアガラス上昇時の衝撃音の発生を防止することができる自動車用ガラスランが開示されている。   For example, Patent Document 1 discloses a glass run including a straight portion and a corner portion, and the door glass rises by increasing the distance between the outer peripheral surface of the bottom wall of the straight portion of the glass run and the door frame. An automotive glass run is disclosed in which the bottom wall center portion can be sufficiently bent when the bottom wall of the glass run is pushed, and the generation of an impact sound when the door glass is raised can be prevented.

特開２００６−１５７７４号公報JP 2006-15774 A

しかしながら、前記自動車用ガラスランの構造では、ガラスランのコーナー部の底壁の外周面とドアフレームとの間隔が大きくなるように形成されていないため、ドアガラスが傾いて上昇した場合には、衝撃音の発生を抑制することができない。   However, in the structure of the glass run for automobiles, because the gap between the outer peripheral surface of the bottom wall of the corner portion of the glass run and the door frame is not increased, when the door glass is tilted and rises, Generation of impact sound cannot be suppressed.

すなわち、ドアガラスが上昇するときに、ドアガラスの汚れなどによりガラスランの車両前側の側縁部と車両後側の側縁部との摩擦力に差異が生じると、ドアガラスが車両前後方向に傾いた状態で上昇することがある。この場合、ドアガラスの角部からガラスランに当接することになるが、ドアガラスの上昇による衝撃が一点に集中するため、その衝突音は、ドアガラスが水平な状態で上昇した場合に比して大きくなってしまう。ところが、前記自動車用ガラスランの構造では、ドアガラスの角部が当接するコーナー部で衝撃を吸収することができない。   That is, when the door glass rises, if there is a difference in the frictional force between the side edge on the front side of the glass run and the side edge on the rear side of the vehicle due to dirt on the door glass, the door glass is moved in the vehicle front-rear direction. May rise in a tilted state. In this case, it will come into contact with the glass run from the corner of the door glass, but the impact caused by the rise of the door glass is concentrated at one point, so the impact sound is higher than when the door glass rises in a horizontal state. Will become bigger. However, in the structure of the glass run for automobiles, the impact cannot be absorbed by the corner portion where the corner portion of the door glass abuts.

そこで、本発明は、ドアガラスが車両前後方向に傾いた状態で上昇した場合であっても、ドアガラスがガラスランの上縁部分に当接する際の衝突音を抑制することが可能な車両用ガラスランを提供することを目的とする。   Therefore, the present invention is for a vehicle capable of suppressing a collision sound when the door glass comes into contact with the upper edge portion of the glass run even when the door glass is lifted in a state of being tilted in the vehicle front-rear direction. The object is to provide a glass run.

本発明は、前記目的を達成するために、車両のドアサッシュの内周面に取り付けられ、ドアガラスの昇降を案内する車両用ガラスランであって、ドアサッシュの内周面に沿って延設され、ドアガラスが閉じられたときにドアガラスの上辺部分が当接する基底部を備え、ドアサッシュの角部近傍の基底部には、ドアサッシュの内周面に対向する面とドアサッシュの内周面との間隔がその他の部分よりも大きく形成され、上昇するドアガラスの角部を受け入れる角受け部が形成され、角受け部のドアガラスが当接する面は、ドアガラスが当接しているときにおける角受け部以外の基底部のドアガラスが当接する面と略同一の高さに形成されていることを特徴とする。   In order to achieve the above object, the present invention is a vehicle glass run that is attached to the inner peripheral surface of a door sash of a vehicle and guides the raising and lowering of the door glass, and extends along the inner peripheral surface of the door sash. The base of the door sash near the corner of the door sash and the inner surface of the door sash. An interval between the peripheral surface is formed larger than other portions, a corner receiving portion for receiving a corner portion of the rising door glass is formed, and a surface on which the door glass contacts the corner receiving portion is in contact with the door glass. It is characterized in that it is formed at substantially the same height as the surface with which the door glass of the base other than the corner receiving portion abuts.

これにより、ドアガラスの上角部が当接する部分の基底部は、ドアサッシュの内周面に対向する面とドアサッシュの内周面との間隔が大きく形成されていることから、ドアガラスの上角部が当接したときの衝撃を、基底部によって吸収することができる。   As a result, the base of the portion where the upper corner of the door glass abuts is formed with a large distance between the surface facing the inner peripheral surface of the door sash and the inner peripheral surface of the door sash. The impact when the upper corner portion comes into contact can be absorbed by the base portion.

本発明によれば、ドアガラスの上角部が当接したときの衝撃を基底部によって吸収することができるので、ドアガラスが車両前後方向に傾いた状態で上昇した場合であっても、ドアガラスがガラスランの上縁部分に当接する際の衝突音を抑制することが可能となる。   According to the present invention, since the impact when the upper corner portion of the door glass comes into contact can be absorbed by the base portion, even if the door glass is lifted in a state of being tilted in the vehicle front-rear direction, the door It is possible to suppress a collision sound when the glass comes into contact with the upper edge portion of the glass run.

ガラスラン４の上縁中部を構成する押出部５は、図３および図４に示すように、車体前後方向に水平に延びる押出基底部５１と、押出基底部５１の外周面に設けられた押出当接部５２と、押出基底部５１の内周面に設けられた押出第１壁部５３および押出第２壁部５４とから構成される。   As shown in FIGS. 3 and 4, the extrusion part 5 constituting the middle part of the upper edge of the glass run 4 includes an extrusion base part 51 extending horizontally in the longitudinal direction of the vehicle body and an extrusion provided on the outer peripheral surface of the extrusion base part 51. It is comprised from the contact part 52 and the extrusion 1st wall part 53 and the extrusion 2nd wall part 54 which were provided in the internal peripheral surface of the extrusion base part 51. FIG.

押出基底部５１は、外周面と内周面とがいずれも平面状に形成されている。また、押出基底部５１の下方には、車外側から車内側に向かって延びる押出リップ５１ａが設けられている。押出リップ５１ａは、下面側がドアガラス３ｃの上辺の外周面と当接し、ドアガラス３ｃの上昇による衝撃を吸収するとともに、ドアガラス３ｃとガラスラン４との間をシールする。   As for the extrusion base part 51, both an outer peripheral surface and an inner peripheral surface are formed in planar shape. Further, an extrusion lip 51 a extending from the vehicle outer side toward the vehicle inner side is provided below the extrusion base portion 51. The extrusion lip 51a is in contact with the outer peripheral surface of the upper side of the door glass 3c on the lower surface side, absorbs the impact caused by the rising of the door glass 3c, and seals between the door glass 3c and the glass run 4.

押出当接部５２は、押出基底部５１の外周面の車外側縁部と車内側縁部から上方に突出して形成されている。押出当接部５２の上端部がドアサッシュ３ｂの上辺の内周面と当接することにより、押出基底部５１の外周面とドアサッシュ３ｂの上辺の内周面との間隔ができる。   The push-out contact portion 52 is formed to protrude upward from the vehicle outer edge and the vehicle inner edge of the outer peripheral surface of the push base 51. When the upper end portion of the push-out contact portion 52 is in contact with the inner peripheral surface of the upper side of the door sash 3b, a space between the outer peripheral surface of the push-out base portion 51 and the inner peripheral surface of the upper side of the door sash 3b is formed.

押出第１壁部５３は、押出基底部５１の内周面の車内側縁部から下方に延びるように形成されている。押出第１壁部５３の下端部には、車外側上方に向かって延びるリップ形状の押出第１シール部５３ａが設けられ、ドアガラス３ｃの上辺の車内側の側面と当接して、ドアガラス３ｃとガラスラン４との間をシールする。   The extruded first wall portion 53 is formed so as to extend downward from the vehicle inner edge portion of the inner peripheral surface of the extruded base portion 51. A lip-shaped extruded first seal portion 53a extending toward the upper outside of the vehicle is provided at the lower end of the extruded first wall portion 53, and comes into contact with the side of the upper side of the door glass 3c on the inner side of the vehicle. And the glass run 4 are sealed.

押出第２壁部５４は、押出基底部５１の内周面の車外側縁部から下方に延びるように形成されている。押出第２壁部５４の下端部には、車内側上方に向かって延びるリップ形状の押出第２シール部５４ａが設けられ、ドアガラス３ｃの上端部の車外側の側面と当接して、ドアガラス３ｃとガラスラン４との間をシールする。   The extruded second wall portion 54 is formed to extend downward from the vehicle outer edge portion of the inner peripheral surface of the extruded base portion 51. The lower end portion of the extruded second wall portion 54 is provided with a lip-shaped extruded second seal portion 54a extending upward in the interior of the vehicle. The lip-shaped extruded second seal portion 54a is in contact with the side surface on the vehicle exterior side of the upper end portion of the door glass 3c. Seal between 3c and glass run 4.

なお、ガラスラン４の側縁中部を構成する押出部５は、ガラスラン４の上縁中部を構成する押出部５と同様の構成であるが、ガラスラン４の側縁中部を構成する押出部５には、押出リップ５１ａが設けられていない点、内周面にはドアガラス３ｃの昇降を案内するための溝が形成されている点、および押出当接部５２の突出高さが低い点で異なっている。   In addition, although the extrusion part 5 which comprises the side edge center part of the glass run 4 is the structure similar to the extrusion part 5 which comprises the upper edge center part of the glass run 4, the extrusion part which comprises the side edge center part of the glass run 4 5, the point where the extrusion lip 51a is not provided, the point where a groove for guiding the raising and lowering of the door glass 3c is formed on the inner peripheral surface, and the protrusion height of the extrusion contact portion 52 is low. Is different.

ガラスラン４の上縁角部を構成する型部６は、ドアサッシュ３ｂの角部近傍に位置し、図３および図５に示すように、ドアサッシュ３ｂの角部の形状に対応して折れ曲がって形成されている。型部６の上辺は、車体前後方向に水平に延びる型基底部６１と、型基底部６１の外周面に設けられた型当接部６２と、型基底部６１の内周面に設けられた型第１壁部６３および型第２壁部６４と、型基底部６１の外周面の一部に設けられた緩衝部６５とから構成される。   The mold part 6 constituting the upper edge corner of the glass run 4 is located in the vicinity of the corner of the door sash 3b, and is bent corresponding to the shape of the corner of the door sash 3b as shown in FIGS. Is formed. The upper side of the mold part 6 is provided on the mold base part 61 extending horizontally in the longitudinal direction of the vehicle body, the mold contact part 62 provided on the outer peripheral surface of the mold base part 61, and the inner peripheral surface of the mold base part 61. The mold first wall 63 and the mold second wall 64, and a buffer 65 provided on a part of the outer peripheral surface of the mold base 61.

型基底部６１は、型基底部６１は、上昇するドアガラス３ｃの角部を受け入れる角受け部を有し、外周面と内周面とがいずれも平面状に形成され、内周面がドアガラス３ｃの上縁部分と当接してドアガラス３ｃとガラスラン４との間をシールする。また、型基底部６１は、押出基底部５１に比して上下方向の厚みが小さく形成されている。型基底部６１の端部は、押出基底部５１の端部と連続するように接続成形されている。   The mold base 61 has a corner receiving portion that receives a corner of the rising door glass 3c, and both the outer peripheral surface and the inner peripheral surface are formed in a flat shape, and the inner peripheral surface is the door. Abutting on the upper edge portion of the glass 3c, the space between the door glass 3c and the glass run 4 is sealed. Further, the mold base 61 is formed with a smaller thickness in the vertical direction than the extruded base 51. The end of the mold base 61 is connected and formed so as to be continuous with the end of the extruded base 51.

型当接部６２は、型基底部６１の外周面の車外側縁部と車内側縁部から上方に突出して形成されている。型当接部６２の上端部がドアサッシュ３ｂの上辺の内周面と当接することにより、型基底部６１の外周面とドアサッシュ３ｂの上辺の内周面との間隔ができる。また、型当接部６２の突出高さは、押出当接部５２の突出高さよりも高く形成されている。型当接部６２の前後方向端部は、押出当接部５２の前後方向端部と連続するように接続成形されている。   The mold contact portion 62 is formed to protrude upward from the vehicle outer edge and the vehicle inner edge of the outer peripheral surface of the mold base 61. When the upper end portion of the mold contact portion 62 contacts the inner peripheral surface of the upper side of the door sash 3b, a space between the outer peripheral surface of the mold base portion 61 and the inner peripheral surface of the upper side of the door sash 3b can be formed. Further, the protruding height of the mold contact portion 62 is formed higher than the protruding height of the push contact portion 52. The front and rear end portions of the mold contact portion 62 are connected and formed so as to be continuous with the front and rear end portions of the push contact portion 52.

型基底部６１は押出基底部５１よりも薄く形成され、かつ、型当接部６２は押出当接部５２よりも高く突出しているため、型基底部６１の外周面とドアサッシュ３ｂの上辺の内周面との間隔は、押出基底部５１の外周面とドアサッシュ３ｂの上辺の内周面との間隔よりも広くなっている。また、型基底部６１の厚さと型当接部６２の突出高さを合わせると、押出基底部５１の厚さ、押出リップ５１ａの厚さ、および押出当接部５２の高さの合計と同程度となるように形成されている。したがって、型基底部６１の内周面は、押出リップ５１ａが下方から押しつけられて押出基底部５１の内周面に当接しているときの押出リップ５１ａの下面の高さと同等程度の高さとなる。   Since the mold base 61 is formed thinner than the extrusion base 51 and the mold contact part 62 protrudes higher than the extrusion contact part 52, the outer periphery of the mold base 61 and the upper side of the door sash 3b are formed. The space | interval with an internal peripheral surface is wider than the space | interval of the outer peripheral surface of the extrusion base part 51, and the internal peripheral surface of the upper side of the door sash 3b. Further, when the thickness of the mold base 61 and the protrusion height of the mold abutting portion 62 are matched, it is the same as the sum of the thickness of the extruded base 51, the thickness of the extruded lip 51a, and the height of the extruded abutting portion 52. It is formed so as to be about. Therefore, the inner peripheral surface of the mold base 61 has a height equivalent to the height of the lower surface of the extrusion lip 51a when the extrusion lip 51a is pressed from below and is in contact with the inner peripheral surface of the extrusion base 51. .

型第１壁部６３は、型基底部６１の内周面の車内側縁部から下方に延びるように形成され、型第１壁部６３の一部は、型部６の折れ曲がり部分を内周側から補強するために下方に大きく形成されている。型第１壁部６３の下端部には、車外側上方に向かって延びるリップ形状の型第１シール部６３ａが設けられ、ドアガラス３ｃの上辺の車内側の側面と当接して、ドアガラス３ｃとガラスラン４との間をシールする。型第１壁部６３の前後方向端部は押出第１壁部５３の前後方向端部と連続し、型第１シール部６３ａの前後方向端部は押出第１シール部５３ａの前後方向端部と連続するように接続成形されている。   The mold first wall portion 63 is formed so as to extend downward from the inner side edge of the inner peripheral surface of the mold base portion 61, and a part of the mold first wall portion 63 has a bent portion of the mold portion 6 as an inner periphery. In order to reinforce from the side, it is formed large downward. The lower end of the mold first wall 63 is provided with a lip-shaped mold first seal portion 63a extending upward on the outside of the vehicle, abutting against the side of the upper side of the door glass 3c on the inside of the vehicle, and the door glass 3c. And the glass run 4 are sealed. The front-rear direction end of the mold first wall 63 is continuous with the front-rear end of the extruded first wall 53, and the front-rear end of the mold first seal 63a is the front-rear end of the extruded first seal 53a. It is connected and molded so as to be continuous.

型第２壁部６４は、型基底部６１の内周面の車外側縁部から下方に延びるように形成されている。型第２壁部６４の下端部には、車内側上方に向かって延びるリップ形状の型第２シール部６４ａが設けられ、ドアガラス３ｃの上辺の車外側の側面と当接して、ドアガラス３ｃとガラスラン４との間をシールする。型第２壁部６４の前後方向端部は押出第２壁部５４の前後方向端部と連続し、型第２シール部６４ａの前後方向端部は押出第２シール部５４ａの前後方向端部と連続するように接続成形されている。   The mold second wall portion 64 is formed to extend downward from the vehicle outer edge portion of the inner peripheral surface of the mold base portion 61. A lip-shaped mold second seal portion 64a extending toward the vehicle interior upper side is provided at the lower end portion of the mold second wall portion 64, and comes into contact with the vehicle outer side surface on the upper side of the door glass 3c, thereby the door glass 3c. And the glass run 4 are sealed. The front-rear direction end portion of the mold second wall portion 64 is continuous with the front-rear direction end portion of the extruded second wall portion 54, and the front-rear direction end portion of the mold second seal portion 64a is the front-rear direction end portion of the extruded second seal portion 54a. It is connected and molded so as to be continuous.

緩衝部６５は、型基底部６１の外周面のうち、押出基底部５１との接続部分に近い部分に、前後方向に並んで複数設けられており、変形によって衝撃を吸収する緩衝部材である。型基底部６１の外周面から上方に突出する緩衝部６５は、上方に向かって前後方向の幅が小さくなるように形成され、三角形状をなしている。複数の緩衝部６５の突出高さは互いに異なっており、押出基底部５１に近い緩衝部６５ほど高く形成されている。   A plurality of buffer parts 65 are provided in the outer peripheral surface of the mold base part 61 near the connection part with the extrusion base part 51 in a line in the front-rear direction, and are shock absorbing members that absorb impact by deformation. The buffer portion 65 protruding upward from the outer peripheral surface of the mold base portion 61 is formed so that the width in the front-rear direction decreases toward the upper side, and has a triangular shape. The protrusion heights of the plurality of buffer portions 65 are different from each other, and the buffer portions 65 closer to the extrusion base portion 51 are formed higher.

なお、型部６の側辺部分は、型部６の上辺部分とほぼ同様の構成であるが、型部６の側辺部分には、緩衝部６５が設けられていない点、型基底部６１の内周面にドアガラス３ｃの昇降を案内するための溝が形成されている点、型基底部６１の厚さと型当接部６２の突出高さが、それぞれ押出基底部５１の厚さと押出当接部５２の突出高さと同じに形成されている点が異なっている。   The side part of the mold part 6 has substantially the same configuration as the upper side part of the mold part 6, but the side part of the mold part 6 is not provided with a buffer part 65, and the mold base part 61. The groove for guiding the raising and lowering of the door glass 3c is formed on the inner peripheral surface of the mold, the thickness of the mold base 61 and the protruding height of the mold abutment 62 are respectively the thickness of the extrusion base 51 and the extrusion. The difference is that it is formed to be the same as the protruding height of the contact portion 52.

以上のように構成された車両用ガラスランを備えた車両１において、ドアガラス３ｃを閉鎖させる操作を行うと、ドアガラス３ｃは、ガラスラン４の側縁中部を構成する押出部５および型部６の側辺部分に案内されて上昇する。そして、ドアガラス３ｃが押出第１シール部５３ａと型第１シール部６３ａとを車内側に押しやり、押出第２シール部５４ａと型第２シール部６４ａとを車外側に押しやりつつ、ドアガラス３ｃの上辺部分が、押出部５の押出リップ５１ａの下面側および型部６の型基底部６１の内周面に当接する。   In the vehicle 1 including the vehicle glass run configured as described above, when the operation of closing the door glass 3c is performed, the door glass 3c is formed by the extruded portion 5 and the mold portion constituting the middle portion of the side edge of the glass run 4. It is guided by the side part of 6 and goes up. The door glass 3c pushes the extruded first seal portion 53a and the mold first seal portion 63a to the inside of the vehicle, and pushes the extruded second seal portion 54a and the mold second seal portion 64a to the outside of the vehicle, The upper side portion of the glass 3 c comes into contact with the lower surface side of the extrusion lip 51 a of the extrusion portion 5 and the inner peripheral surface of the die base portion 61 of the die portion 6.

ドアガラス３ｃが押出リップ５１ａの下面側と型基底部６１の内周面に当接した後もなお上昇すると、押出リップ５１ａがドアガラス３ｃの上昇による衝撃を吸収しながら上面が押出基底部５１の内周面に当接するまで押し上げられるとともに、押出基底部５１と型基底部６１とがドアガラス３ｃの上昇による衝撃を吸収しながら上方に撓む。押出基底部５１は、押出当接部５２の突出高さの分だけ撓むことが可能であり、型基底部６１は、型当接部６２の突出高さの分だけ撓むことが可能である。   When the door glass 3c still rises after contacting the lower surface side of the extrusion lip 51a and the inner peripheral surface of the mold base 61, the upper surface of the extrusion base 51 is absorbed while the extrusion lip 51a absorbs the impact caused by the rise of the door glass 3c. The extruded base 51 and the mold base 61 bend upward while absorbing the impact caused by the rising of the door glass 3c. The extrusion base portion 51 can be bent by the protrusion height of the extrusion contact portion 52, and the mold base portion 61 can be bent by the protrusion height of the die contact portion 62. is there.

ここで、ドアガラス３ｃは、汚れなどによる摩擦力の変化によりドアガラス３ｃの前後の一方が上昇中に引っかかり、車両前後方向のいずれかに傾いた状態（前または後ろに転んだ状態）で上昇する場合がある。例えば、ドアガラス３ｃの前側の摺動抵抗が後側の摺動抵抗よりも高くなった場合、ドアガラス３ｃは車両前後方向の後側を上方にして傾いた状態で上昇する。   Here, the door glass 3c is caught in a state where one of the front and rear sides of the door glass 3c is rising due to a change in frictional force due to dirt or the like, and is tilted in either the vehicle front-rear direction (a state where the vehicle falls forward or backward). There is a case. For example, when the sliding resistance on the front side of the door glass 3c becomes higher than the sliding resistance on the rear side, the door glass 3c rises with the rear side in the vehicle front-rear direction facing upward.

車両前後方向の後側を上方にして傾いた状態で上昇したドアガラス３ｃは、ドアガラス３ｃの後側上角部から角受け部となる型基底部６１の車両前後方向後側の内周面に当接し、型基底部６１の後側部分を押し上げる。   The door glass 3c that is lifted with the rear side in the vehicle front-rear direction upward is inclined to the inner peripheral surface on the rear side in the vehicle front-rear direction of the mold base 61 that serves as a corner receiving part from the rear upper corner portion of the door glass 3c. And the rear portion of the mold base 61 is pushed up.

そして、ドアガラス３ｃの上角部の上昇が型基底部６１の内周面に当接して停止した後も、ドアガラス３ｃの前後方向の前側は上昇を続け、ドアガラス３ｃは、上角部を回転中心として回転するようにして、傾いた状態から水平な状態となっていく。そのため、ドアガラス３ｃの上辺の外周面は、型基底部６１車両前後方向の後側からに当接していった後に、押出基底部５１の車両前後方向の後側から当接していき、最終的にドアガラス３ｃの上辺の全ての外周面が、押出部５および型部６の内周面に当接して、ドアガラス３ｃが閉じられる。   And even after the rise of the upper corner of the door glass 3c comes into contact with the inner peripheral surface of the mold base 61 and stops, the front side of the door glass 3c continues to rise, and the door glass 3c As a center of rotation, the tilted state becomes horizontal. Therefore, the outer peripheral surface of the upper side of the door glass 3c abuts from the rear side in the vehicle front-rear direction of the die base 61 in the vehicle front-rear direction, and then abuts from the rear side in the vehicle front-rear direction of the extrusion base 51. All the outer peripheral surfaces of the upper side of the door glass 3c come into contact with the inner peripheral surfaces of the extruded portion 5 and the mold portion 6, and the door glass 3c is closed.

このように、本実施形態の車両用ガラスランによれば、型部６の型基底部６１は押出基底部５１よりも薄く形成され、かつ、型当接部６２は押出当接部５２よりも高く突出しているので、型基底部６１の外周面は押出基底部５１の外周面よりも低くなっている。したがって、ドアガラス３ｃの上角部が当接する部分の外周面とドアサッシュ３ｂの上辺の内周面との間隔が大きく形成されている。これにより、ドアガラス３ｃが車両前後方向に傾いた状態で上昇してドアガラス３ｃの角部からガラスラン４の上縁部分に当接する場合、ドアガラス３ｃの角部が当接する型基底部６１が大きく上方に撓むことにより、一点に集中したドアガラス３ｃの上昇による衝撃を充分に吸収することができる。そのため、ドアガラス３ｃが車両前後方向に傾いた状態で上昇した場合であっても、衝撃を吸収して衝突音を抑制することが可能となる。   Thus, according to the vehicle glass run of this embodiment, the mold base 61 of the mold 6 is formed thinner than the extruded base 51, and the mold abutting part 62 is smaller than the extruded abutment 52. Since it protrudes high, the outer peripheral surface of the mold base 61 is lower than the outer peripheral surface of the extruded base 51. Therefore, the space | interval of the outer peripheral surface of the part which the upper corner | angular part of the door glass 3c contact | abuts, and the inner peripheral surface of the upper side of the door sash 3b is formed large. Accordingly, when the door glass 3c is tilted in the vehicle front-rear direction and comes into contact with the upper edge portion of the glass run 4 from the corner portion of the door glass 3c, the mold base portion 61 with which the corner portion of the door glass 3c comes into contact. Is greatly bent upward, it is possible to sufficiently absorb the impact caused by the rising of the door glass 3c concentrated on one point. Therefore, even when the door glass 3c is lifted in a state where the door glass 3c is tilted in the vehicle front-rear direction, it is possible to absorb the impact and suppress the collision sound.

また、型基底部６１の内周面は、押出リップ５１ａが下方から押しつけられて押出基底部５１の内周面に当接しているときの押出リップ５１ａの内周面の高さと同等程度の高さとなっている。したがって、型基底部６１と押出基底部５１との厚さは互いに異なっていても、ドアガラス３ｃの上辺の外周面が当接する部分の高さは同じであるため、ドアガラス３ｃとガラスラン４との間を確実にシールすることができる。   Further, the inner peripheral surface of the mold base 61 has a height equivalent to the height of the inner peripheral surface of the extrusion lip 51 a when the extrusion lip 51 a is pressed from below and is in contact with the inner peripheral surface of the extrusion base 51. It has become. Therefore, even if the thickness of the mold base 61 and the extruded base 51 is different from each other, the height of the portion where the outer peripheral surface of the upper side of the door glass 3c abuts is the same, so the door glass 3c and the glass run 4 Can be reliably sealed.

また、型基底部６１の外周面の押出基底部５１との接続部分に近い部分には、前後方向に並んだ複数の緩衝部６５が設けられている。当該部分は、型基底部６１の内周面にドアガラス３ｃの角部が当接しない部分の反対面となる。これにより、ドアガラス３ｃが車両前後方向に傾いた状態で上昇してドアガラス３ｃの角部からガラスラン４の上縁部分に当接する場合、ドアガラス３ｃの角部が当接する型基底部６１の撓みによってドアガラス３ｃの上昇による衝撃を吸収した後に、さらに緩衝部６５によって衝撃を吸収することができる。   Further, a plurality of buffer portions 65 arranged in the front-rear direction are provided in a portion of the outer peripheral surface of the mold base portion 61 that is close to the connection portion with the extrusion base portion 51. This portion is the opposite surface of the portion where the corner portion of the door glass 3 c does not contact the inner peripheral surface of the mold base 61. Accordingly, when the door glass 3c is tilted in the vehicle front-rear direction and comes into contact with the upper edge portion of the glass run 4 from the corner portion of the door glass 3c, the mold base portion 61 with which the corner portion of the door glass 3c comes into contact. After the shock due to the rise of the door glass 3c is absorbed by the bending of the shock, the shock can be further absorbed by the buffer portion 65.

さらに、複数の緩衝部６５の突出高さは互いに異なっており、押出基底部５１に近い緩衝部６５ほど高く形成されている。これにより、車両前後方向に傾いた状態でドアガラス３ｃが上昇した場合、ドアガラス３ｃの上角部が型基底部６１の内周面に当接した後に、ドアガラス３ｃが上角部を回転中心として回転するようにして傾いた状態から水平な状態となっていく際に、複数の緩衝部６５が同時にドアガラス３ｃの上昇による衝撃を受けることができる。   Furthermore, the protruding heights of the plurality of buffer parts 65 are different from each other, and the buffer parts 65 closer to the extruded base part 51 are formed higher. Thereby, when the door glass 3c rises in a state tilted in the vehicle front-rear direction, the door glass 3c rotates the upper corner after the upper corner of the door glass 3c contacts the inner peripheral surface of the mold base 61. When changing from a tilted state to a horizontal state so as to rotate as the center, the plurality of buffer portions 65 can simultaneously receive an impact due to the rising of the door glass 3c.

なお、前記実施形態では、押出基底部５１の下方に、押出基底部５１の外周面と平行に延びる押出リップ５１ａが設けられているが、これに限らず、例えば、押出基底部５１の下方に押出基底部５１と平行に延びる壁部を設け、当該壁部と押出基底部５１の内周面との間に中空部を形成するようにしてもよい。   In addition, in the said embodiment, although the extrusion lip 51a extended in parallel with the outer peripheral surface of the extrusion base part 51 is provided under the extrusion base part 51, it is not restricted to this, For example, under the extrusion base part 51 A wall portion extending in parallel with the extruded base portion 51 may be provided, and a hollow portion may be formed between the wall portion and the inner peripheral surface of the extruded base portion 51.

また、前記実施形態では、緩衝部６５の形状は三角形状をなしているが、これに限らず、例えば、四角形状やアーチ形状などをなしていてもよい。   Moreover, in the said embodiment, although the shape of the buffer part 65 has comprised the triangle shape, it may not be restricted to this, for example, may comprise a square shape, an arch shape, etc.

さらに、前記実施形態では、複数の緩衝部６５は互いに上方への突出高さが異なっているが、これに限らず、複数の緩衝部６５の上方への突出高さを同一としてもよい。複数の緩衝部６５の上方への突出高さを同一に形成することにより、型部６の成形が容易となる。   Furthermore, in the above-described embodiment, the plurality of buffer portions 65 have different upward projecting heights. However, the present invention is not limited to this, and the plurality of buffer portions 65 may have the same upward projecting height. Forming the mold part 6 is facilitated by forming the plurality of buffer parts 65 to have the same protruding height.
