In addition, according to the utility model, the second break that keeps lip is arranged on the open side that base portion is installed, for example be arranged on the side that keeps lip as the bight, and the car outer lateral side of flange that is located at thin-walled S during with the projecting strip part moving contact, than the car inner side surface of the flange of thin-walled S more on the position by the car outside, therefore, even if the flange of thin-walled S, flange also can be clamped between the front end and projecting strip part that keeps lip firmly.
In addition, according to the utility model, the second break that keeps lip is arranged on the open side that base portion is installed, for example be arranged on the side that keeps lip as the bight, and with the maintenance lip of the car inner side surface moving contact of the flange of thin-walled be smooth from the second break to front end, therefore, uprise with the degree of being close to of flange, and can further improve confining force.
In addition, according to the utility model, in the cross sectional shape that keeps lip, make the side of the diapire side that base portion is installed towards the open side curved, take when being installed on thickness of slab as the flange of heavy wall T, between the car inner side surface that keeps lip and installation base portion, produce the gap, therefore, come the power of self-sustaining lip can directly not be passed to greatly the car inner side surface, by this, can prevent to be installed on thickness of slab is the broaden situation of such " grinning out " of the opening of installation base portion of opening trim bar of the flange of heavy wall T.
In addition, according to the utility model, all formed by expanded material because base portion and projecting strip part and maintenance lip are installed, therefore, can realize the lightweight of opening trim bar integral body.
In addition, according to the utility model, owing to be formed with thickness is the taper thickening to the diapire side from the open side that base portion is installed rake at projecting strip part, therefore, even if keep the front end of lip and relative projecting strip part Elastic Contact, the front end of maintenance lip also can be along rake swimmingly towards the deflection of car inside side walls side.
By this, when the opening trim bar is installed on flange, can prevent to keep the front end of lip to be hooked in the projecting strip part side and to make the sharply such situation of increase of load of inserting.

Referring to figs. 1 through Fig. 5, the opening trim bar 30 of the utility model embodiment is described.Fig. 1 is the cutaway view of the opening trim bar 30 of expression the utility model embodiment, and Fig. 2 to Fig. 5 is expression opening trim bar 30 and the cutaway view of the flange 102 of installing, 103 relation.
The opening trim bar 30 of the utility model embodiment comprises to be installed base portion 31, projecting strip part 32, keep lip 33 and is embedded in the core 34 that base portion 31 is installed, and it can be installed in from thickness of slab is that flange 102 to the thickness of slab of heavy wall T is on the flange of flange 103 of thin-walled S.At this, owing to form the flange 102 of heavy wall T by stacked three flanges, form the flange 103 of thin-walled S by a stacked flange, therefore, it also can be installed on the flange of stacked two flanges in the middle of it.As the wall thickness of the flange 102 of the heavy wall T of thickness of slab maximum, use the flange of 5～10 millimeters (mm), as the wall thickness of the flange 103 of the thin-walled S of thickness of slab minimum, use the flange of 0.5～5 millimeter (mm).
The installation base portion 31 of opening trim bar 30 is made of with the diapire 31c that is connected above-mentioned two sidewall 31a, 31b car outside sidewall 31a, car inside side walls 31b, its cross section is roughly U font, thereby can embed wherein in the mode of inserting from the open side that base portion 31 is installed along the flange 102,103 of the car door opening circumference setting of auto body.At this, show the example of the same length in the cross sectional shape that makes car outside sidewall 31a and car inside side walls 31b, but also can make their length different.
Projecting strip part 32 is provided with two (its quantity is not particularly limited) in the inboard (car is inboard) of the car outside sidewall 31a that base portion 31 is installed across certain intervals, opening trim bar 30 is being installed on flange 102, at 103 o'clock, projecting strip part 32 and the flange 102 that inserts from the open side that base portion 31 is installed, 103 car outer lateral side moving contact.
In addition, form thickness at projecting strip part 32 and be the rake 32a of taper thickening from open side to the diapire 31c side that base portion 31 is installed, by this, the cross sectional shape of projecting strip part 32 is the approximate right angle triangle.
Keep lip 33 to be arranged to that the cross section is roughly that ligule ground rolls near the inboard the car inside side walls 31b end towards diapire 31c tiltedly and sidewall 31a extension outside the car.At this, keep lip 33 to extend with the angle of about 60 degree with respect to the bearing of trend of car inside side walls 31b, if but reduce angle, owing to the confining force that for thickness of slab is the flange 103 of thin-walled S reduces, and be the flange 102 of heavy wall T for thickness of slab, may keep lip 33 to make the opening of the installation base portion 31 of opening trim bar 30 broaden such " grinning out " with car inside side walls 31b butt, therefore, it is desirable in the scope of 45 degree～70 degree, preferably in the scope of 55 degree～65 degree.
In addition, the wall thickness of the wall ratio car outside sidewall 31a of maintenance lip 33 and the car inside side walls 31b of section is large.
In addition, make length L in the cross sectional shape that keeps lip 33 form than between the opening of the car outside sidewall 31a that base portion 31 is installed and car inside side walls 31b apart from M length, and be installed on flange 102, under the state before 103, make and keep the position P that leans on the car outside most of lip 33 front ends to be accommodated in 32 of two projecting strip parts, the position of car inboard of leaning on most than projecting strip part 32 (is being installed on flange 102, in 103 the situation, because projecting strip part 32 is pressed towards the direction of car outside sidewall 31a, therefore, be to be positioned at than flange 102, the position of 103 car outer lateral side is slightly by the position outside the car) more by the car outside, and the position that does not contact with car outside sidewall 31a.That is to say that what keep lip 33 front ends is set between the face (car inner side surface) by sidewall 31a inboard outside the position of car inboard and the car of projecting strip part 32 by the position P in the car outside.
In addition, to keep the length setting of the front end of lip 33 to be: under the state that makes these maintenance lip 33 bendings with the side by diapire 31c one side that keeps lip 33 towards the close mode of car inside side walls 31b (for example in Fig. 3), even keep front end and the diapire 31c butt of lip 33, this front end can be out of shape by diapire 31c bending yet.In addition, in Fig. 3, show keep lip 33 front end not with the situation of diapire 31c butt.
In addition, on the side of opening one side by installation base portion 31 in keeping lip 33 (face side that keeps lip 33), be provided with the first break 41 and the second break 42 as the bight near car inside side walls 31b with near sidewall 31a place, the car outside, so that keep 33 easy minutes two stages of lip towards the bending of diapire 31c side.Namely, in the cross sectional shape that keeps lip 33, opening one side by installation base portion 31 in keeping lip 33, the line that connects the first break 41 and the second break 42 is than being connected line as the position of the car inside side walls 31b that keeps lip 30 roots and the first break 41 more towards the diapire 31c lopsidedness that base portion 31 is installed, and connect the second break 42 with keep lip 33 front ends by the line of the position P in the car outside than the line that is connected this first break 41 and the second break 42 more towards the diapire 31c lopsidedness of installation base portion 31.
In addition, although be smooth between the first break 41 to second breaks 42, also can form towards the open side curved that base portion 31 is installed.In addition, the second break 42 is smooth between the front end that keeps lip 33, thereby when being installed on the flange 103 of thin-walled S, the car inner side surface of the whole zone of its tabular surface and flange 103 is close to.
Before opening trim bar 30 is installed on flange 102, the set positions of the first break 41 the car outer lateral side of the flange 102 of heavy wall T during with projecting strip part 32 moving contact, than the car inner side surface of the flange part 102 of heavy wall T more by the position of car inboard.On the contrary, if be positioned at car inner side surface than the flange 102 of heavy wall T more by the position in the car outside, then owing to keep the rigidity of lip 33 to become strong, therefore, be positioned at by the position of car inboard even more ideal.
Before opening trim bar 30 is installed on flange 103, the set positions of the second break 42 the car outer lateral side of the flange 103 of thin-walled S during with projecting strip part 32 moving contact, than the car inner side surface of the flange part 103 of thin-walled S more by the position in the car outside.In addition, comparatively it is desirable to, even if after installation, also with the car inner side surface of the set positions of the second break 42 flange 103 when the car outer lateral side of the flange 103 of thin-walled S and projecting strip part 32 moving contact, thin-walled S and the position between the car outer lateral side.
In addition, the diapire 31c side in the front end that keeps lip 33 is cut and forms recess 36, with the wall thickness of attenuate front end.
In addition, in the cross sectional shape that keeps lip 33, diapire 31c one side by installation base portion 31 in the maintenance lip 33 (rear side that keeps lip 33) forms towards the single curved surface (radius of curvature R) of the open side that base portion 30 is installed (face side of maintenance lip 33) curved between position to the position that is formed with recess 36 as the car inside side walls 31b that keeps lip 30 roots.
Being embedded in the core 34 that base portion 31 is installed is that the cross section is roughly U font with base portion 31 is installed equally, and buries underground along base portion 31 is installed.As core 34, for example, but used thickness is the core of 0.3 millimeter thin-walled, and can use metal core.
In addition, on car inside side walls 31b and connection location that diapire 31c is connected, be provided with towards the inboard cross section of extending of car and be the roughly decoration lip 35 of ligule.
Consist of opening trim bar 30 installation base portion 31, projecting strip part 32, keep lip 33 and decorate lip 35 being formed by expanded material, this expanded material for example is 0.4～0.8 EPDM(ethylene propylene diene rubber by proportion) or the TPE(thermoplastic elastomer) the foam sponge material that forms, thereby with resinous core 34, realize the lightweight of opening trim bar 30 integral body.
Then, the situation that the opening trim bar 30 that will consist of as mentioned above is installed on flange describes.
When opening trim bar 30 being installed on thickness of slab being the flange 102 of heavy wall T, as shown in Figure 2, if in the mode that flange 102 is inserted from the open side that base portion 31 is installed opening trim bar 30 and flange 102 are embedded near also (among Fig. 2 towards upside), then keep the more forward part of ratio first break 41 of lip 33 centered by the first break 41 towards the diapire 31c side bending that base portion 31 is installed, make the position and the car inner side surface moving contact of flange 102 of the first break 41 of keeping lip 33 and 42 of the second breaks, and make the projecting strip part 32 of being located at installation base portion 31 and the car outer lateral side moving contact of flange 102.
In addition, in case opening trim bar 30 is embedded flange 102, then as shown in Figure 3, flange 102 is in the state between the position that is clamped in 42 of the first break 41 of keeping lip 33 and the second breaks and two projecting strip parts 32, thereby opening trim bar 30 is installed on the flange 102.
At this moment, want the antagonistic force that restores to be delivered on the flange 102 from the position of 42 of the first break 41 and the second breaks owing to keep ratio the first break 41 more forward parts of the bending centered by the first break 41 of lip 33, and flange 102 pressed towards projecting strip part 32 1 sides, therefore, opening trim bar 30 can be installed on stable state flange 102.In addition, when opening trim bar 30 is installed, owing to keep lip 33 energetically bending centered by the first break 41, therefore, even if the flange 102 that thickness of slab is larger also can easily insert it from the open side that base portion 31 is installed, and can easily opening trim bar 30 be embedded.
In addition, keep the side by diapire 31c one side (rear side) that base portion 31 is installed in the lip 33 to form towards the single curved surface of the open side that base portion 30 is installed (face side of maintenance lip 33) curved, therefore, when opening trim bar 30 is installed, between the car inside side walls 31b that keeps lip 33 and installation base portion 31 gap Q can appear.By this, even if keep lip 33 as shown in Figure 3 towards the significantly deflection of car inside side walls 31b side, owing to keeping gap Q to occur between lip 33 and the car inside side walls 31b, therefore, come the power of self-sustaining lip 33 can directly not be delivered to greatly on the car inside side walls 31b.The broaden situation of such " grinning out " of the opening of installation base portion 31 that by this, can prevent to be installed on the opening trim bar 30 of flange 102.
In addition, residual between the front end that keeps lip 33 and diapire 31c have a little gap N.
In addition, are sponge materials owing to keep lip 33, therefore, even if keep lip 33 and car inside side walls 31b butt, also can prevent " grinning out " by the deflection that keeps lip 33 self.If car inside side walls 31b also is sponge material, then better effects if.
In addition, when opening trim bar 30 is installed on flange 102, even if keep the front end of lip 33 and relative projecting strip part 32 Elastic Contact, owing to be formed with the rake 32a of taper at projecting strip part 32, therefore, the front end that keeps lip 33 along rake 32a glibly towards the deflection of car inside side walls 31b side.By this, when opening trim bar 30 is installed on flange 102, can prevent to keep the front end of lip 33 to be hooked in projecting strip part 32 sides and to make the sharply such situation of increase of load of inserting.
Then, when opening trim bar 30 is installed on thickness of slab and is the flange 103 of thin-walled S, as shown in Figure 4, keep the more forward part of ratio first break 41 of lip 33 centered by the first break 41 towards the diapire 31c side bending that base portion 31 is installed, keep the car inner side surface bending towards flange 102 centered by the second break 42 of the more forward part of ratio second break 42 of lip 33, thereby make the position of 42 of the front end that keeps lip 33 and the second breaks and the car outer lateral side moving contact of flange 103.
By this, flange 103 is in the state between the position that is clamped in 42 of the front end that keeps lip 33 and the second breaks and two projecting strip parts 32, thereby opening trim bar 30 is installed on the flange 103.
At this moment, because except the antagonistic force that ratio the first break 41 more forward parts of the bending centered by the first break 41 that keeps lip 33 are wanted to restore, keep ratio the second break 42 more forward parts of the bending centered by the second break 42 of lip 33 to want the antagonistic force that restores also can be concentrated and be delivered on the flange 103 with the position of 42 of the second breaks from the front end that keeps lip 33, and flange 103 pressed towards projecting strip part 32 1 sides, therefore, opening trim bar 30 can be installed on stable state flange 103.Particularly, by diapire 31c one side by base portion 31 is installed that keeps lip 33 front ends is cut, just can make and keep the deflection quantitative change of lip 33 front ends large, in addition, owing to keep lip 33 to be formed by the foam sponge material, therefore, bite with the state of being close on a large scale with the car inner side surface of flange 103 at the position that keeps 42 of the front end of lip 33 and the second breaks.
By this, as shown in Figure 5, even if the direction (downside among Fig. 5) of opening trim bar 30 being extracted at the state that is installed on the flange 103 of thin-walled S from opening trim bar 30 applies effectively, the antagonistic force that concentrates on the position of 42 of the front end that keeps lip 33 and the second breaks also can be applied on the flange 103, and between the position and projecting strip part 32 of 42 of the front end that flange 103 is clamped in firmly keep lip 33 and the second breaks, therefore, even if use metal-made or the resinous core of thin-walled to be used as core 34, also opening trim bar 30 easily can't be separated with flange 103.
And, because it is smooth keeping front end and 42 of second breaks of lip 33, therefore, and the position of 42 of the front end of the maintenance lip 33 of the car inner side surface moving contact of flange 103 and the second breaks is with respect to degree of the being close to height of flange 103, and can further improve confining force.
In addition, when opening trim bar 30 is installed, because the part of ratio the first break 41 more forward sides of maintenance lip 33 is by bending, and the part of ratio the second break 42 more forward ends is also by bending, therefore, flange 103 that can thickness of slab is thinner easily inserts from the open side that base portion 31 is installed, and can easily embed opening trim bar 30.
Like this, opening trim bar 30 according to present embodiment, be that flange (for example situation of stacked three flanges) 102 to the thickness of slab of heavy wall T is the flange (for example situation of a flange) 103 of thin-walled S from thickness of slab, all can opening trim bar 30 be installed with enough confining forces, and, flange 102,103 easily can be inserted from the open side that base portion 31 is installed.
In addition, being installed on flange 102,103 opening trim bar 30 forms car outside sidewall 31a is sealed inside and outside coming car with hollow sealing section (not shown) Elastic Contact of being located at vehicle door side.In addition, also can form at the car outside sidewall 31a hollow sealing section is set, and when closing car door, make hollow sealing section and the car door Elastic Contact of being located at opening trim bar side come the car inboard is sealed.
In addition, in the present embodiment, make and keep front end and 42 of second breaks of lip 33 to be smooth, thereby can to make itself and thickness of slab be flange 103 moving contacts of thin-walled S under the state in zone is close in increase, but, also can as shown in Figure 6, make front end and 42 open side curved towards installation base portion 31 of the second break of keeping lip 33.
In addition, in the present embodiment, by diapire 31c side being cut make the rigidity that keeps lip 33 front ends less than the rigidity at other position that keeps lip 33, the deflection of the front end that keeps lip 33 is increased, but, as shown in Figure 7, also breach can be set especially, and by making the rigidity that keeps lip 33 front ends form the front end of maintenance lip 33 than the little such material of rigidity at other position that keeps lip 33.
In addition, in the present embodiment, opening one side by base portion 31 is installed in keeping lip 33 arranges the first break 41, but replace this means, also can be as shown in Figure 8, diapire 31c one side by installation base portion 31 in keeping lip 33, and lean on car inside side walls 31b one side that breach 37 or slit are set.
In addition, in the present embodiment, diapire 31c one side (rear side that keeps lip 33) by base portion 31 is installed in keeping lip 33, to form from position to the position that is formed with recess 36 as the car inside side walls 31b that keeps lip 33 roots towards the single curved surface (radius of curvature R) of the open side that base portion 30 is installed (face side that keeps lip 33) curved, but so long as towards the shape of the open side that base portion 30 is installed (face side that keeps lip 33) curved, when opening trim bar 30 is installed, between the car inside side walls 31b that keeps lip 33 and installation base portion 31, form gap Q, just can prevent from the power of self-sustaining lip 33 directly to be passed to greatly car inside side walls 31b, therefore, also can not single curved surface.
In addition, in the present embodiment, in opening trim bar 30, all parts except core 34 all are made of the foam sponge material, even if only keep lip 33 or only directly clamped flanges 102,103 projecting strip part 32 and to keep lip 33 be to be made of the foam sponge material but form, also can obtain enough confining forces.
In addition, in the present embodiment, as core 34, for example, use the core of 0.3 millimeter such thin-walled of thickness, but also can use the core of heavy wall, in addition, be not limited to metal core, also can use resinous core.
