DAMPER DEVICE
The present invention relates to a damper device which is used as an abutment stopping member for adjusting a 5 closed position of, for example, a bonnet or hood, a trunk or boot lid, a door, or the like of a vehicle.
The above-described damper device abuts against a hood, a trunk cover, or a door which is closed, for 10 stopping the same, and in order to make the line of the hood, trunk cover, or door which is closed correspond with the body line, it is used to adjust the height of the closed hood or trunk cover, or adjust the position of the closed door. Conventionally, such a damper device is formed 15 by a damper main body which is cylindrical and at whose outer periphery a male screw is formed, and a grommet at which a female screw, which engages the male screw of the damper main body, is formed and which is mounted to a member to be mounted to.
Next, the mounting of the damper device will be explained. First, by using a mounting hole provided at a predetermined position of a vehicle body, the grommet is 25 mounted to the hole of the vehicle body. Then, the damper device is mounted to the vehicle body by screwing the male screw of the damper main body with the female screw of the grommet so as to mount the damper main body to the grommet.
30 Next, adjustment of the projecting length of the damper main body which projects from the grommet will be described. First, in case the projecting length of the damper main body is long, i.e., in case the line of the hood 35 projects outwardly above the body line, the damper main body is rotated and is screwed further with respect to the grommet such that the screwed length of the female screw
À 2 with respect to the male screw, i.e., the screwed length of the grommet with the damper main body, becomes longer. In this way, the projecting length of the damper main body from the grommet is made shorter.
Further, in case the projecting length of the damper main body is short, i.e., in case the line of the hood is lower than the body line, the damper main body is rotated and the screwing of the damper main body with the grommet 10 is adjusted such that the screwed length of the grommet with the damper main body becomes shorter. By making the screwed length shorter, the projecting length of the damper main body from the grommet becomes longer.
15 In this way, by rotating the damper main body with respect to the grommet, the projecting length of the damper main body from the grommet is adjusted to a predetermined length, so that the body line and the line of the hood match. The body line and the line of the hood can thereby 20 be made to match each other.
Note that such a damper device is disclosed in, for example, Japanese Utility Model Publication (KOKOKU) No. 7-
4905. In this conventional damper device, in case the projecting length of the damper main body from the grommet is to be adjusted, the gap (difference in heights) between the body line and the line of the hood is measured. On the 30 basis of this gap, the projecting length of the damper main body is adjusted by visual estimation. Thus, the projecting length of the damper main body must be adjusted two or three times until the gap between the body line and the line of the hood is eliminated, and thus, work efficiency 35 is poor.
À 3 The present invention has been developed in order to overcome the above-described drawbacks, and an object of the present invention is to provide a damper device which enables the projecting length of a damper main body to be 5 adjusted and set to a desired length easily and with good work efficiency.
A damper device according to the present invention comprises a damper main body having a male screw to be 10 fixed to a fixing member with a female screw so as to change a screwed length with respect to the female screw of the fixing member, wherein said damper device further comprises indicating means for indicating a change amount of the screwed length provided at at least one of the 15 damper main body and the fixing member, said indicating means indicating a rate by which the screwed length of the damper main body changes due to a rotation of the damper main body such that a projection length of the male screw with respect to the fixing member is changed.
A Particular embodiment in accordance with this invention will now be described with reference to the accompanying drawings; in which: 25 Fig. 1 is an exploded perspective view of a damper device which is a different embodiment of the present invention; Fig. 2 is a plan view of a grommet shown in Fig. 1; Fig. 3 is a front view of the grommet shown in Fig. 1; Fig. 4 is a bottom view of the grommet shown in Fig. 1; Fig. 5 is a crosssectional view taken along line 13 13 of Fig. 2; and
À 4 Fig. 6 is an explanatory view showing a way of mounting the damper device, which is the different embodiment of the present invention, to a panel, and a way of adjusting a projecting length of a damper main body.
Hereinafter, an embodiment of the present invention will be described on the basis of the drawings.
In the drawings, numeral 41 denotes a damper main body 10 formed of rubber. The damper main body 41 is formed by a head portion 42 which is disc-shaped, and a shaft portion 43 which is formed integrally with the head portion 42 and extends downward from the center of the bottom surface of the head portion 42. An indication mark 42a, which is 15 shaped as an isosceles triangle and points toward a radially outer side, is provided at the periphery of the upper surface of the head portion 42. A male screw 44 is provided at the shaft portion 43 from the lower end to the upper end side thereof.
Numeral 51 denotes a grommet which is formed of synthetic resin. The grommet 51 is formed by a tube portion 52 which is circular in a plan view, a flange 53 which is formed continuously with the upper end (one end) of the 25 tube portion 52 so as to surround the upper end and extend outwardly, two elastic nipping pieces 54 which are formed at opposing positions of the tube portion 52 such that the panel P is nipped by the elastic nipping pieces 54 and the flange 53, and a female screw 55 formed at the inner side 30 of the tube portion 52 formed integrally therewith.
A detent projection 56 is formed continuously along the axial direction at the outer peripheral surface of the tube portion 52. The detent projection 56 functions as 35 a detent for the grommet 51 by engaging a projected hole r of the panel P.
À 5 Graduations 53a are formed on the upper surface (the surface at the side opposite to the tube portion 52) of the flange 53. The graduations 53a indicate how many millimeters the projecting length changes by rotating the 5 damper main body 41 by 45 , due to the pitch of the male screw 44 and the female screw 55. In the present embodiment, the graduations 53a show that the projecting length changes by 0.5 mm by rotating the damper main body 41 by 45 .
P denotes the panel as the member to be mounted. A mounting hole h which is circular and into which the tube portion 52 can be fit, and the projected hole r which extends in the radial direction of the mounting hole h, are 15 formed in the panel P. Next, an example of mounting the damper device will be described. First, the lower side of the tube portion 52 is placed 20 to coincide with the mounting hole h, and the detent projection 56 is arranged to coincide with the projected hole r. Then, the grommet 51 is pushed toward the panel P. Thus, the elastic nipping pieces 54, top portions of which project from the outer periphery of the tube portion 52, 25 are pushed by the edge of the panel P so as to be deflected inwardly. Then, when the elastic nipping pieces 54 pass through the panel P and the flange 53 abuts against the upper side 30 of the panel P. the elastic nipping pieces 54 return to their original states due to the elasticity thereof and abut against the lower side of the panel P. As shown in Fig. 6, because the panel P is nipped by the flange 53 and the elastic nipping pieces 54, the tube portion 52 is 35 mounted to the panel P.
À 6 Then, the damper main body 41 is screwed into the grommet 51. When the damper device is mounted in this way, the indication mark 42a of the damper main body 41 is made to match the graduation 53a.
Next, adjustment of the projecting length of the damper main body 41 will be described.
First, a hood (not shown) is lowered by being closed, 10 and the gap (difference in heights) between the body line and the line of the hood is measured. Then, if the line of the hood is higher than the body line, i.e. , if the hood projects out from the body, the hood is opened, and in order to make the projecting length of the damper main body 15 41 shorter, the damper main body 41 is rotated in the clockwise direction (the direction in which the screwed length of the male screw 44 and the female screw 55 becomes longer) by an angle which corresponds to the measured value. For example, if the measured value is 2.0 mm, the 20 damper main body 41 is rotated by 1800. by setting the indication mark 42a to correspond to the graduation S3a which is "2'', adjustment of the projecting length of the damper main body 41 is completed.
25 When the line of the hood is lower than the body line, i.e., when the hood is concave with respect to the body, the hood is opened, and in order to make the projecting length of the damper main body 41 longer, the damper main body 41 is rotated in the counterclockwise direction (the 30 direction in which the screwed length of the male screw 44 and the female screw 55 becomes shorter) by an angle which corresponds to the measured value. For example, if the measured value is 1.5 mm, the damper main body 41 is rotated by 135 . By setting the indication mark 42a to 35 correspond to the graduation 53a which is "1.5", adjustment of the projecting length of the damper main body 41 is completed.
As described above, in accordance with this embodiment of the present invention, a projecting length change amount indicting means (the indication mark 42a and the graduations 53a), which shows the rate by which the 5 projecting length of the damper main body 41 changes, is provided at the damper main body 41 and the flange 53.
Thus, by rotating the damper main body 41 with respect to the grommet 51 while watching the projecting length change amount indicating means, the projecting length of the 10 damper main body 41 can be adjusted and set to the desired length simply and with good work efficiency.
In the above embodiments, the head portion 42 are provided at the damper main body 41. However, the same 15 functions are achieved even if the head portions 42 is not provided. When the head portion 42 is not provided, the same functions can be achieved if the graduations forming the projecting length change amount indicating means are provided at the periphery of the top surface of the shaft 20 portion 43. The graduations 53a which form the projecting length change amount indicating means are provided at the flange 53. However, the grommet 51 can be omitted by providing the female screw at the panel P by tapping and providing the graduations at the panel P. Further, the projecting length change amount indicating means is formed by the indication mark 42a and the graduations 53a. However, even if the projecting length change amount indicating means is formed only by the 30 indication mark or only by the graduations, and this projecting length change amount indicating means is provided at the damper main body or at the member at which the female screw is provided, the projecting length of the damper main body can be adjusted by rotating the damper 35 main body while watching the projecting length change amount indicating means.
À 8 Further, a projecting length change amount indicating means, which shows the rate by which the projecting length of the damper main body changes, is provided at the damper main body and the member. Thus, by rotating the damper main 5 body with respect to the member while watching the projecting length change amount indicating means, the projecting length of the damper main body can be adjusted and set to the desired length simply and with good work efficiency.
