Description

  The present invention relates to a glass run.

  Generally, a glass run is provided along the inner periphery of a door frame of an automobile. The glass run has a substantially U-shaped cross section including a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion when viewed from a cross-sectional direction perpendicular to the longitudinal direction, and both sides. A vehicle interior seal lip and a vehicle exterior seal lip extending from the tip of the wall portion toward the inside of the main body portion are provided. The glass run is sealed so that the body portion is attached to a mounting portion provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass moving up and down are sandwiched by both seal lips. .

  By the way, when the upper edge of the door glass is formed obliquely in accordance with the window shape of the door, the upper side provided corresponding to the upper edge of the door glass in the glass run also extends obliquely. Can be installed. In such a door, when the door glass is pressed against the upper side portion of the glass run when the window portion is closed, stress on the upper side portion acts obliquely upward along the longitudinal direction, and in some cases There is a risk that the upper side portion may be displaced in the longitudinal direction, contracted, or crushed (deformed into a wavy shape). In this case, there is a concern that the sealing performance may be deteriorated or the mounting state may be deteriorated.

  On the other hand, for example, it is conceivable to provide a hard part made of a hard resin in the side wall part so that it is difficult to expand and contract in the longitudinal direction of the glass run (for example, see Patent Document 1). By adopting this configuration, as described above, it is possible to suppress a problem such that the upper side portion contracts in the longitudinal direction or collapses when the window portion is closed.

Japanese Patent No. 3132039

  However, the upper side portion of the door frame (the upper edge portion of the window portion) is often curved or bent so as to protrude toward the outer peripheral side of the window portion. Therefore, there is a concern that it will be difficult to follow and deform the glass run in accordance with the curved shape of the door frame only by providing the hard part on the side wall part. May be invited.

  The present invention has been made in view of the above circumstances, and the object thereof is to suppress positional displacement, contraction deformation of the device itself in the longitudinal direction, and the like while suppressing deterioration in workability of attachment to the attachment portion. To provide a glass run.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A base portion and a pair of vehicle inner side wall portions and a vehicle outer side wall portion extending from the base portion and having a substantially U-shaped cross section are attached to an attachment portion provided along the inner periphery of the vehicle door frame. In a glass run comprising: a main body portion to be worn; and a vehicle inner seal lip and a vehicle outer seal lip extending from the side wall portions to the inside of the main body portion,
The upper side portion provided corresponding to the upper edge portion of the door glass that moves up and down is harder than the base material constituting the main body portion and the seal lip in at least one of the vehicle inner side wall portion and the vehicle outer side wall portion. A hard portion made of a resin is provided along the longitudinal direction of the upper side portion,
The hard part passes through a center of gravity position in a cross section when the upper side part is cut in a direction perpendicular to the longitudinal direction, and at least one of the hard parts is on a virtual straight line perpendicular to the front and back surfaces of the door glass. The glass run is provided at a position away from each boundary portion between the base portion and the seal lip in the side wall portion so that the portion is positioned.

  According to the means 1, since the hard part made of hard resin is provided along the longitudinal direction of the upper side part of the glass run, the upper side part can be made difficult to expand and contract in the longitudinal direction. Therefore, when the upper edge of the glass run is installed obliquely because the upper edge of the door glass is inclined, the upper edge is pushed up to the door glass when the door window is closed. Even so, the hard portion will be stretched against the stress to compress the upper side portion in the longitudinal direction. As a result, it is possible to suppress a situation in which the upper side portion is crushed in such a manner that it is compressed in the longitudinal direction.

  In addition, when the glass run is attached to the attachment portion, when the upper side portion is made to follow and deform in accordance with the shape of the attachment portion that is curved or bent so as to be convex in the outer peripheral direction of the window portion, The part on the seal lip side that is the inner peripheral side of the part is contracted in the longitudinal direction of the upper side part, and the part on the base part side that is the outer peripheral side of the window part in the side wall part is extended in the longitudinal direction of the upper side part. It is done. Therefore, if the width of the hard part in the extending direction from the base part of the side wall part is long, the follow-up deformation of the side wall part is inhibited, and even if it is formed short, it is close to the base part and the seal lip. If provided, the follow-up deformation may be hindered.

  On the other hand, according to this means 1, the hard part passes through the center of gravity position in the cross section of the upper side part of the glass run, and at least a part thereof is located on a virtual straight line perpendicular to the front and back surfaces of the door glass. The side wall portion is provided at a position away from the boundary portion with the base portion and the seal lip. That is, as described above, when the side wall portion is bent or bent in the outer peripheral direction of the window portion, the side wall portion contracts with a portion extending in the longitudinal direction of the main body portion at a certain point in the extending direction from the base portion. It can be said that the certain point is a portion that is most difficult to expand and contract in the longitudinal direction of the main body. The certain point is present at or near a portion that intersects the virtual straight line. For this reason, by providing a hard part so that at least one part may be located on the said virtual straight line, the influence on the followable deformability of an upper side part by providing a hard part can be made small as much as possible. Therefore, even if a hard part is provided on the upper side part, the upper side part can be deformed relatively smoothly in accordance with the curved shape of the door frame, resulting in a decrease in mounting workability and stability of the mounting state. Can be prevented.

  Mean 2. The glass run according to means 1, wherein the hard portion is configured such that a width of the side wall portion in the extending direction from the base portion is equal to or less than a width in the thickness direction of the side wall portion. .

  No matter how much the cross-sectional area of the hard part is required in order to obtain the strength capable of preventing the deformation of the upper side part in the longitudinal direction when the window part is closed, as in the case 2, in the extending direction of the side wall part By configuring so that the width of the hard portion does not become as long as possible, the effect of the means 1 such as improving the shape followability to the mounting portion and improving the workability of mounting can be achieved more reliably.

  Examples of the cross-sectional shape of the hard portion include a square shape, or a rectangular shape in which the width in the extending direction of the side wall portion is shorter than the width in the thickness direction of the side wall portion. When the width of the hard part is larger than the thickness of the corresponding side wall part, the hard part may be provided so as to protrude from the side wall part to the inner peripheral side of the main body part. In this case, the hard part can be configured not to protrude from the outer peripheral surface of the main body part of the side wall part, and the hard part is caught by the edge of the sash part when attached to the sash part, so that it is difficult to push inward. The situation can be avoided.

  Means 3. The glass run according to means 1 or 2, wherein at least the outer peripheral surface of the main body portion is covered with a covering portion made of a material softer than the hard portion.

  According to the means 3, when the door frame vibrates or the like, it is possible to avoid a situation in which a relatively large noise is generated due to contact between the hard portion and the mounting portion. In addition, a coating | coated part may be comprised with the material same as a base material, and when a sliding layer is integrally formed in the glass sliding surface etc. of a seal lip, you may be comprised with the formation material. When these configurations are employed, the manufacturing workability of the upper side can be improved. In particular, when the former configuration is employed, the manufacturing apparatus can be further simplified.

  Means 4. 4. The glass run according to any one of means 1 to 3, wherein both the base material and the hard part are mainly composed of an olefin resin material.

  According to the means 4, it is possible to suppress a situation in which the hard part is peeled off from the base material. Therefore, for example, it is possible to prevent various inconveniences such as the effect of preventing the expansion and contraction in the longitudinal direction of the upper side portion from diminishing and the hard portion falling off when the hard portion is exposed from the side wall portion. In addition, compared to the case where a metal hard part is provided on the side wall part, while improving manufacturing workability, it is possible to suppress variations in the relative position of the hard part and to recycle the glass run (material The work at the time of reuse can be simplified.

It is a front schematic diagram which shows schematic structure of a door. It is the JJ sectional view taken on the line of FIG. It is sectional drawing of the glass run in another embodiment.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, a front door (hereinafter simply referred to as “door 1”) that can be opened and closed at an opening for a door of an automobile has a door glass G that can be raised and lowered to open and close a window W of the door 1. And a glass run 5 that is provided corresponding to the outer peripheral shape of the door glass G, guides the raising and lowering of the door glass G, and seals between the peripheral portion of the door glass G and the door frame 2. Yes. The upper side portion of the door frame 2 of the present embodiment is inclined upward toward the rear side (right side in FIG. 1), and protrudes to the outer peripheral side of the window portion W (front and upward; upper left side in FIG. 1). It has a curved shape. In addition, the vehicle inner side surface S1 and the vehicle outer side surface S2 constituting the front and back surfaces of the door glass G extend in parallel to each other (see FIG. 2).

  Further, the glass run 5 includes an extrusion molding portion 6 corresponding to the upper edge portion of the door glass G, extrusion molding portions 7 and 8 corresponding to the longitudinal edge portions before and after the door glass G, and extrusion molding portions 6-7 and 6. It is comprised from the shaping | molding parts 9 and 10 which connect the terminal parts of -8. Each extrusion molding part 6-8 is formed in the substantially linear form with the extruder which is not shown in figure. The mold forming sections 9 and 10 are connected and molded by a mold apparatus (not shown) so that the two extrusion forming sections 6-7 and 6-8 are connected to each other at a predetermined angle. The sash portion DS formed along the inner periphery of the door frame 2 and the channel portion DC provided in the door panel 3 so as to extend downward in the longitudinal direction of the front and back of the sash portion DS, 5 is attached. In the present embodiment, the sash part DS and the channel part DC correspond to the attachment part.

  As shown in FIG. 2, the extruded portion 6 includes a base portion 14, a vehicle inner side wall portion 15 and a vehicle outer side wall portion 16 extending from the base portion 14, and has a substantially U-shaped cross section. A body portion 11 fitted into a U-shaped sash portion DS (channel portion DC), a vehicle inner side seal lip 12 extending from the front end portion of the vehicle inner side wall portion 15 toward the vehicle outer side, and a front end portion of the vehicle outer side wall portion 16 And an outside seal lip 13 extending toward the inside of the vehicle. In a state where the window portion W is closed by the door glass G, the vehicle inner side seal lip 12 is pressed against the vehicle inner side surface S1 of the door glass G, and the vehicle outer side seal lip 13 is pressed against the vehicle outer side surface S2 of the door glass G. Press contact. Thereby, the vehicle inner side and the vehicle outer side of the door glass G are each sealed. In FIG. 2, the right side of the drawing is the inside of the vehicle, and the left side of the drawing is the outside of the vehicle.

  In addition, the extrusion molding parts 7 and 8 and the mold molding parts 9 and 10 have basically the same cross-sectional shape as the extrusion molding part 6 and are provided with a main body part 11 and seal lips 12 and 13. (Not shown). Further, in the present embodiment, the upper side portion of the sash portion DS (corresponding to the upper side portion of the door frame 2 that is inclined upward toward the rear while being curved so as to be convex toward the outer peripheral side of the window portion W ( Similarly, the upper edge portion of the window portion W and the upper edge portion of the door glass G are also inclined upward while being curved. For this reason, the extrusion molding part 6 attached to the upper side part of the sash part DS is also curved so as to be convex toward the outer peripheral side of the window part W and extends so as to incline upward toward the rear. .

  Now, in this embodiment, in the vehicle interior side wall portion 15 and the vehicle exterior side wall portion 16 of the extrusion molding portion 6 that constitutes the upper side portion of the glass run 5, from the base material that constitutes the main body portion 11, the seal lips 12, 13 and the like. Further, a vehicle inner side hard portion 21 and a vehicle outer side hard portion 22 made of a hard olefin resin are provided. The base material of this embodiment is made of TPO (olefin-based thermoplastic elastomer), and the hard portions 21 and 22 are made of polypropylene. Moreover, the extrusion molding part 6 is formed by co-extrusion molding the site | part comprised with base materials, such as the main-body part 11, and the hard parts 21 and 22. FIG. In addition, the extrusion molding part 6 is formed in the substantially linear shape by the extrusion molding, and will be curved following it by attaching to the sash part DS.

  The hard portions 21 and 22 pass through the center of gravity X in the cross section when the extruded portion 6 of the glass run 5 in the attached state to the sash portion DS is cut in a direction perpendicular to the longitudinal direction, and the window At least a part is located on a virtual straight line Y (part intersecting the virtual straight line Y) extending perpendicularly to the surface of the door glass G (the vehicle inner side surface S1 and the vehicle outer side surface S2 parallel to each other) in a state where the portion W is closed Are arranged to be.

  Moreover, the cross-sectional shapes of the hard portions 21 and 22 are substantially square. In this embodiment, the length of one side of each hard part 21 and 22 provided in each side wall part 15 and 16 is slightly smaller than the thickness t1 and t2 of the corresponding side wall part 15 and 16, respectively. Therefore, by providing the hard portions 21 and 22 at the above positions, the hard portions 21 and 22 are separated from the boundary portion between the side wall portions 15 and 16 and the base portion 14, and the side wall portions 15 and 16 and the seal lip are separated. 12 and 13 are also separated from the boundary portion. And when the extrusion molding part 6 is made to follow and deform | transform so that it may attach to the curved sash part DS, the site | part of the base part 14 side rather than the hard parts 21 and 22 is extended in a longitudinal direction among the side wall parts 15 and 16. The parts closer to the seal lips 12 and 13 than the hard parts 21 and 22 contract in the longitudinal direction.

  Of the side walls 15, 16, the portion intersecting the virtual straight line Y contracts with the portion extending in the longitudinal direction of the extruded portion 6 when being curved following the curved shape of the sash portion DS. It corresponds to a portion where the portion is switched, and is the portion that is most difficult to expand and contract in the longitudinal direction of the extruded portion 6. That is, the hard parts 21 and 22 are provided at positions where the follow-up deformability when attached to the sash part DS has as little influence as possible.

  Furthermore, the coating | coated part 25 which covers the surface of the outer peripheral side of the main-body part 11 among the hard parts 21 and 22 is provided. The covering portion 25 of the present embodiment is formed by turning TPO constituting the base material around the outer peripheral surface of the hard portions 21 and 22. Further, the surface of the covering portion 25 is formed flush with the outer peripheral surface of the main body portion 11 of the side wall portions 15 and 16. On the other hand, of the hard portions 21 and 22, the inner peripheral surface of the main body portion 11 is exposed to be flush with the inner peripheral surface of the main body portion 11 of the side wall portions 15 and 16. Yes.

  As described above in detail, according to the present embodiment, the hard parts 21 and 22 made of PP are provided along the longitudinal direction of the extrusion part 6 constituting the upper side part of the glass run 5. The part 6 can be made difficult to expand and contract in the longitudinal direction. Therefore, when the extrusion molding part 6 is installed obliquely because the upper edge part of the door glass G is inclined or the like, the extrusion molding part 6 is connected to the door when the window part W of the door 1 is closed. Even if pushed up by the glass G, the hard portions 21 and 22 are stretched against the stress to compress and push the extruded portion 6 in the longitudinal direction. As a result, it is possible to suppress a situation in which the extrusion molding portion 6 is crushed in such a manner that it is compressed in the longitudinal direction.

  Further, when attaching the extrusion molding part 6 to the sash part DS, when deforming the extrusion molding part 6 following the shape of the sash part DS that is curved so as to be convex in the outer peripheral direction of the window part W, Of the side wall parts 15 and 16, the seal lip 12 and 13 side part which is the inner peripheral side of the window part W is contracted in the longitudinal direction of the extrusion molding part 6. The base portion 14 side, which is the side, is extended in the longitudinal direction of the extrusion molding portion 6. Accordingly, the extending direction of the side wall parts 15 and 16 from the base part 14 (the direction orthogonal to the thickness direction of the side wall parts 15 and 16; in FIG. If the width of the hard portions 21 and 22 in the extending direction of the side wall portion 16 is shown as L2, the follow-up deformation of the side wall portions 15 and 16 is obstructed. If it is provided in the vicinity of the portion 14 and the seal lips 12 and 13, the follow-up deformation may be hindered.

  On the other hand, according to this embodiment, the hard parts 21 and 22 pass on the center of gravity position X in the cross section of the extrusion molding part 6 and are on a virtual straight line Y perpendicular to the front and back surfaces S1 and S2 of the door glass G. At least a part of the side wall portions 15 and 16 is provided at a position away from the boundary between the base portion 14 and the seal lips 12 and 13 so that at least a part thereof is located. That is, as described above, when the side wall parts 15 and 16 are curved in the outer peripheral direction of the window part W, the side wall parts 15 and 16 extend in the longitudinal direction of the main body part 11 at a certain point in the extending direction from the base part 14. However, it can be said that the certain point is a portion that is most difficult to expand and contract in the longitudinal direction of the main body 11. The certain point is present at or near a portion that intersects the virtual straight line Y. For this reason, by providing the hard parts 21 and 22 so that at least a part is located on the virtual straight line Y, the influence on the follow-up deformability of the extruded part 6 due to the provision of the hard parts 21 and 22. Can be made as small as possible. Accordingly, even if the extrusion molding part 6 is provided with the hard parts 21 and 22, the extrusion molding part 6 can be deformed relatively smoothly in accordance with the curved shape of the door frame 2, and as a result, installation workability and attachment can be improved. It is possible to prevent a decrease in state stability.

  Moreover, the hard parts 21 and 22 are comprised by the cross-sectional substantially square shape. For this reason, even if the cross-sectional area is the same, the hard part 21 in the extending direction of the side wall parts 15 and 16 is compared with the case where a rectangular hard part whose cross-sectional shape is long along the extending direction of the side wall parts 15 and 16 is provided. , 22 can be shortened. Therefore, the above-described effects such as improving the shape followability to the sash portion DS and improving the mounting workability can be more reliably achieved.

  Furthermore, the outer peripheral surface of the main body 11 among the hard parts 21 and 22 is covered with a covering part 25 made of the same TPO as the base material. For this reason, when the door 1 vibrates, the situation where the hard parts 21 and 22 and the sash part DS contact and a comparatively big noise generate | occur | produces can be avoided. The glass run 5 has a base material made of TPO and hard portions 21 and 22 made of polypropylene. Since both TPO and polypropylene (PP) are olefin resins, they have good compatibility. For this reason, the situation where the hard parts 21 and 22 will peel from a base material can be suppressed. Therefore, for example, the effect of preventing the expansion and contraction in the longitudinal direction of the extrusion molding part 6 is diminished, or when the hard parts 21 and 22 are provided exposed from the side wall parts 15 and 16, the hard parts 21 and 22 fall off. Various problems such as these can be prevented. Further, for example, it is not necessary to provide a configuration for preventing peeling as in the case where the hard portion is made of metal, and therefore, improvement in manufacturing workability and the like can be achieved.

  Further, for example, it is possible to suppress variation in the relative positions of the hard portions 21 and 22 and to recycle (reuse constituent materials) as compared to the case where the hard portion is configured by a metal wire having flexibility. It is possible to simplify the work at the time. In addition, for example, there is no need to provide a stopper that protrudes upward from a portion that constitutes the upper side portion of the glass run 5 in the mold forming portion 9 and is hooked on the edge of the sash portion DS or the edge of the sash portion DS. Even in this case, it is possible to prevent displacement of the upper side portion of the glass run 5. For this reason, the trouble of providing a stopper or providing a hole for the stopper in the sash portion DS can be saved, the manufacturing workability can be improved, and the cost can be reduced.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the glass run 5 of the front door is embodied. However, the glass run 5 of the rear door may be applied. Moreover, although the upper edge part of the door glass G of the said embodiment is curving, you may bend so that it may be comprised from a horizontal part and an inclination part. Further, although not particularly mentioned in the above embodiment, the door 1 is provided with a channel member between the outer panel and the inner panel constituting the door frame 2, or a molding member is attached to the end of the outer panel or the inner panel. It is not limited to the type to be used, and a type without a channel member (channelless structure) may be adopted. In other words, in the above embodiment, the extrusion molding unit 6 can be prevented from shifting in the longitudinal direction without hooking the extrusion molding unit 6 to the sash portion DS. Even if it is applied to a glass run to be attached, the same effects as those of the above-described embodiment are surely achieved.

  (B) In the said embodiment, although the hard parts 21 and 22 are provided in the extrusion molding part 6 which comprises the upper side part of the glass run 5, the extrusion molding parts 7 and 8 which comprise the front and back longitudinal side parts, and a type | mold It is good also as providing the hard parts 21 and 22 also in the shaping | molding parts 9 and 10. FIG. For example, when the hard molding parts 21 and 22 are provided in the extrusion molding parts 7 and 8, the situation where the extrusion molding parts 7 and 8 fold upward as the door glass G rises can be avoided more reliably. Can do.

  Moreover, in the said embodiment, although the hard parts 21 and 22 are provided in both the vehicle outer side wall part 16 and the vehicle inner side wall part 15, what is necessary is just to be provided in at least one. However, when the window portion W is closed, there is a concern that a shift in the longitudinal direction may occur between the side wall portion 15 and the side wall portion 16 provided with the hard portion and the portion where the hard portion is not provided. Therefore, it is desirable to provide both.

  (C) In the above-described embodiment, the outer peripheral portion of the main body 11 is covered with the TPO that is the base material of the main body 11 among the hard parts 21 and 22. In order to improve, it is also possible to cover with a material (for example, TPO harder than the base material) constituting the sliding layer which is coextruded on the glass sliding surfaces of the seal lips 12 and 13. However, it is desirable that the covering portion 25 be made of a material softer than the hard portions 21 and 22 in order to suppress the generation of abnormal noise.

  Further, the outer peripheral surface of the main body 11 of the hard parts 21 and 22 may not be covered. Further, for example, as shown in FIG. 3, a recess 31 is formed on the vehicle outer side of the vehicle outer side hard portion 22 without covering the vehicle outer surface of the vehicle outer side hard portion 22 provided on the vehicle outer side wall portion 16 with TPO or the like. As described above, the vehicle-side hard portion 22 may be provided at a position that is more immersed than the vehicle-side surface of the vehicle-side side wall portion 16. In this case, it is possible to suppress the contact between the vehicle outer side hard portion 22 and the sash portion DS, and even if they come into contact with each other, it is possible to prevent the generation of relatively large abnormal noise. Such a configuration can also be applied to the vehicle interior side wall portion 15 and the vehicle interior rigid portion 21.

  (D) In the said embodiment, although the hard parts 21 and 22 are comprised by the cross-sectional substantially square shape, it is not necessarily limited to this shape. However, if the hard portions 21 and 22 are extended vertically (in the extending direction of the side wall portions 15 and 16) in order to ensure the rigidity of the hard portions 21 and 22, there is a possibility that the following deformability of the side wall portions 15 and 16 is lowered. For this reason, it is desirable to extend it laterally (thickness direction of the side wall parts 15 and 16) as necessary, and to make the vertical widths of the hard parts 21 and 22 shorter than the horizontal width or substantially the same. The cross-sectional shape is not necessarily limited to a rectangular shape, and may be somewhat rounded, circular, elliptical, oval, or the like.

  Further, for example, as shown in FIG. 3, when the width of the vehicle inner side hard portion 21 is larger than or equal to the thickness of the vehicle inner side wall portion 15, the vehicle inner hard portion 21 is moved from the vehicle inner side wall portion 15 to the inside of the main body portion 11. It is good also as providing so that it may protrude in the circumference side. In this case, it is possible to avoid a situation in which the vehicle inner hard portion 21 protrudes from the vehicle inner side wall portion 15 to the outer peripheral side (vehicle inner side) of the main body portion 11. Therefore, when the glass run 5 is attached to the sash portion DS, it is possible to prevent a situation in which the in-vehicle hard portion 21 is caught by the sash portion DS and becomes difficult to push.

  Further, as described above, when the vehicle inside hard portion 21 is protruded to the inner peripheral side of the main body portion 11, the door glass G enters the inside of the main body portion 11 as shown in FIG. When 12 is elastically deformed, a sub lip 33 that contacts the back surface of the vehicle interior seal lip 12 and supports the door glass G in cooperation with the vehicle interior seal lip 12 extends from the front end portion of the vehicle interior rigid portion 21. It is also possible to make it. In this case, the sub lip 33 can be shortened, and resource saving can be achieved. Further, the base portion of the sub lip 33 is stabilized, and the vehicle interior seal lip 12 can be supported more reliably. These configurations can be applied to the vehicle outer side wall portion 16 and the vehicle outer side hard portion 22.

  (E) Although not particularly mentioned in the above embodiment, the virtual straight line Y may be configured to pass through the centers (centers of gravity) of the hard portions 21 and 22. In this case, even if the extruded portions 6 are provided with the hard portions 21 and 22, the effect that the extruded portions 6 can be deformed relatively smoothly according to the curved shape of the door frame 2 is further exhibited. The Rukoto.
