Description

[Detailed Description of the Invention] The present invention relates to an ashtray device for a vehicle, and in particular, when the ashtray is pulled out from the retainer while the vehicle is running, the ashtray is prevented from wobbling in the vertical direction. The present invention relates to an ashtray device for a vehicle that prevents the occurrence of abnormal noise due to the wobbling and can always maintain a good function as an ashtray.

Conventionally, as shown in FIGS. 1 to 7, a vehicle ashtray device 1 includes a retainer 3 fixed to an instrument panel 2, a linear spring 4 attached to the retainer, and a linear spring 4 that slides on the retainer 3. It is equipped with an ashtray 5 that can be freely inserted. The retainer 3 is made of sheet metal and has a rectangular shape.The front part corresponding to the insertion opening for the ashtray 5 is open, and the other three sides are surrounded by upright left and right side walls 3a and rear side wall 3b. ing. Further, guide portions 3c curved inwardly toward the bottom are formed on the left and right side wall portions 3a, respectively, and a step portion 3d is formed near the lower end front portion of each guide portion.

The linear spring 4 is formed in a U-shape, and includes a base portion 4a rotatably supported by a pair of bearing portions 6 disposed at the front portion of the retainer 3, and a curved portion 4b curved downward into an arch shape. It is made up of

The ashtray 5 is formed in a rectangular shape and includes a pair of sliding parts 5a that are inserted into the guide parts 3c of the retainer 3 and can slide along the guide parts, and a cigarette butt storage part 5b.
, a gripping portion 5c, and a projection 5d which abuts against the stepped portion 3d of the retainer 3.

As shown in FIG. 3, when the ashtray 5 is inserted into the retainer 3, the curved portion 4b of the linear spring 4 is pressed and bent by the top surface 5e of the ashtray 5, and the elasticity of the linear spring 4 at this time is The ashtray 5 is pressed downward by the force and is prevented from falling off the retainer 3. Further, as shown by the imaginary line in FIG. 5, when the ashtray 5 is pulled out from the retainer 3, the protrusion 5d of the ashtray 5 comes into contact with the step 3d of the retainer 3, so that the ashtray 5 does not fall off the retainer 3. It's getting old. Furthermore, as shown in FIG.
When taking out the ashtray from the retainer 3, the user grips the grip portion 5c of the ashtray 5 and pulls out the ashtray in the direction of arrow B while pressing the ashtray in the direction of arrow A against the elastic force of the linear spring 4. At this time, a gap C is formed between the retainer 3 and the top surface 5e of the ashtray 5, as shown in FIGS. The ashtray 5 is designed to be tiltable.

Since the conventional vehicle ashtray device 1 is configured as described above, when the ashtray 5 is pulled out from the retainer 3 while the vehicle is running, as shown in FIG. The vicinity of the right end of the ashtray 5e is pressed by the curved portion 4b of the linear spring 4, and the ashtray 5 can be tilted in the direction of the arrow D until the top surface 5e abuts the bearing portion 6. In this case, the ashtray 5 can also be tilted in the direction of arrow A, as shown in FIG. Therefore, in the conventional example, when the ashtray 5 is pulled out from the retainer 3 while the vehicle is running,
There is a possibility that the ashtray may wobble in the vertical direction, and this wobbling causes the disadvantage that an abnormal noise is generated.

Furthermore, Japanese Utility Model Application No. 59-163398 discloses a drawer-type box retainer in which a protrusion is provided on the entrance side of a protrusion located at the back, but in this conventional example, the spring is not a linear spring. It is a leaf spring, and is not formed integrally on the left and right sides of the ashtray, and furthermore, the protrusion and the protrusion are formed as separate spring systems independently of each other, and there is no dependent spring between them. No relationship exists. For this reason, in the conventional example, the pair of left and right springs must be fixed to the housing with screws, which requires extra man-hours to assemble, and also requires space between the protrusion and the protrusion to install the screws. Therefore, the overall length of the spring becomes long, which is inconvenient for making the ashtray device more compact.

The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to provide a retainer, an ashtray slidably inserted into the retainer, and an ashtray attached to the lower surface near the entrance of the retainer. A U-shaped linear spring whose base is pivotally mounted and which presses the top surface of an ashtray inserted into the retainer by a pair of left and right curved parts extending inward from the base,
The linear spring is provided with a pair of protrusions that protrude downward near the base between the base and the curved part, and the lower surface of the protrusions is slightly connected to the top surface of the ashtray inserted into the retainer. Disposed with a gap, and formed continuously within the same spring system of U-shaped linear springs so that the protruding part and the curved part have mutually different spring constants and maintain a dependent relationship. By doing so, even if the ashtray pulled out from the retainer tries to vibrate while the vehicle is running, the top surface of the ashtray is brought into contact with the pair of protrusions to prevent the ashtray from wobbling in the vertical direction. In addition, it prevents the occurrence of abnormal noise due to the wobbling and maintains the function of the ashtray in good condition at all times, and also simplifies the structure of the spring to facilitate its assembly. To further reduce the size of an ashtray device by making the length shorter.

In short, the present invention includes a retainer, an ashtray slidably inserted into the retainer, and a base pivoted to a lower surface near the entrance of the retainer, and a top surface of the ashtray inserted into the retainer extending inward from the base. A U-shaped linear spring that is pressed by a pair of left and right curved parts is formed in the linear spring 4 near the base between the base and the curved part so as to protrude downward. a pair of protrusions, the lower surface of the protrusions being disposed with a slight gap from the top surface of the ashtray inserted into the retainer, and the protrusions and the curved portion having different spring constants; The U-shaped linear springs are formed continuously within the same spring system so as to maintain a dependent relationship.

The present invention will be explained below based on embodiments shown in the drawings. FIG. 8 shows a vehicle ashtray device 11 according to the present invention.
is a vertical cross-sectional view of the retainer 3.
Since the ashtray 5 and the ashtray 5 are the same as those of the conventional device 1 shown in FIGS. 1 to 7, the same parts are given the same reference numbers and the explanation will be omitted.

The linear spring 12 is formed in a U-shape, and has a pair of bearings 6 disposed near the entrance of the retainer 3.
(only one of which is shown) is rotatably supported by a base 12a, and a pair of protrusions 12b formed in an arc shape and extending deeper from the vicinity of the base and protruding downward.
and a pair of curved parts 12c which are formed to be curved downward in an arcuate shape continuously from the protrusion part, and whose lower surfaces are disposed slightly below the lower surface of the protrusion part 12b.

Further, when the ashtray 5 is inserted into the retainer 3, the lower surface of the protrusion 12b is the top surface 5e of the ashtray 5.
They are arranged with a slight gap E between them. Further, the distance L between the arc center O of the protruding portion 12b and the center of the base portion 12a is set to be considerably shorter than the length of the curved portion 12c. And the protruding portion 12b and the curved portion 12
c are formed continuously within the same spring system of U-shaped linear springs 12 so as to maintain a dependent relationship by having spring constants different from each other.

When the ashtray 5 is inserted into the retainer 3, the pair of curved portions 12c of the linear spring 12 are pressed and bent by the top surface 5e of the ashtray, and due to the elastic force of the linear spring 12 at this time, , when the top surface 5e of the ashtray 5 is pressed and the ashtray 5 is pulled out from the retainer 3, even if the ashtray tries to vibrate, the top surface 5e of the ashtray comes into contact with the protrusion 12b, causing the ashtray to move vertically. The structure is such that wobbling is regulated.

The present invention is constructed as described above, and its operation will be explained below. As shown in FIG. 8, when the ashtray 5 is in use after being pulled out from the retainer 3, the top surface 5e of the ashtray 5 is pressed by the elastic force of the curved portion 12c of the linear spring 12.
Therefore, the ashtray 5 will not fall off from the retainer 3. At this time, since the lower surface of the protrusion 12b of the linear spring 12 is arranged with a small gap E from the top surface 5e of the ashtray 5, when the ashtray 5 normally slides,
The top surface 5e of the ashtray does not come into contact with the protrusion 12b, so the ashtray 5 slides smoothly inside the retainer 3 while being lightly pressed by the elastic force of the curved part 12c of the linear spring 12. do.

Further, the arc center O of the protrusion 12b of the linear spring 12
The distance L between the center of the base portion 12a and the center of the base portion 12a is set to be quite short, and the spring constant is considerably larger than that of the curved portion 12c.
When the top surface 5e of the linear spring 12 comes into contact with the protrusion 12b, the linear spring 12 hardly bends even if the spring constant suddenly increases within the same spring system. Furthermore, as described above, the lower surface of the protruding portion 12b of the linear spring 12 is arranged with a slight gap E from the top surface 5e of the ashtray 5, so that when the ashtray 5 is pulled out from the retainer 3, Even when the vehicle is running, the ashtray 5 almost never wobbles in the vertical direction. Also, no abnormal noise is generated due to wobbling.

Further, when taking out the ashtray 5 from the retainer 3, the ashtray 5 is tilted and pulled out as in the conventional example shown in FIG. The operation of taking out the ashtray 5 is carried out smoothly and without any trouble, as in the conventional example.

As described above, the present invention includes a retainer, an ashtray that is slidably inserted into the retainer, and a base that is pivotally attached to the lower surface near the entrance of the retainer, and the top surface of the ashtray that is inserted into the retainer is moved to a depth from the base. A U-shaped linear spring that is pressed by a pair of left and right curved parts extending from the base, and a U-shaped linear spring that is formed to protrude downward near the base between the base and the curved part. A pair of protrusions are provided, the lower surface of the protrusions is disposed with a slight gap from the top surface of the ashtray inserted into the retainer, and the protrusions and the curved portion have different spring constants. Since the U-shaped linear springs are formed continuously within the same spring system to maintain a dependent relationship, even if the ashtray pulled out from the retainer tries to vibrate while the vehicle is running,
The top surface of the ashtray comes into contact with the protrusion, which prevents the ashtray from wobbling in the vertical direction, and also eliminates the occurrence of abnormal noises caused by wobbling, allowing the ashtray to always function well. Since the structure of the ashtray device can be simplified and its assembly can be facilitated, and the length of the spring can be shortened, the ashtray device can be made even more compact.
