Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a drawer device such as an ashtray device or a cup holder, and more particularly to a drawer device that prevents the generation of abnormal noises when the drawer is pulled out.

[Prior Art] For example, a cup holder, an ashtray device, etc. need only protrude into the vehicle interior when in use, and it is desirable that they do not protrude into the vehicle interior when not in use. For this reason, cup holders, ashtray devices, and the like of automobiles have conventionally been configured as drawer devices formed in instrument panels and the like. In such a drawer device, a locking pawl provided on one side of the case housing the drawer member and the drawer member comes into contact with a locking wall provided on the other side, thereby regulating the amount of drawout of the drawer member. It is said that

[Problems to be solved by the invention] In recent years, the sound insulation of automobiles has progressed, and there is a demand for quiet interiors of vehicles. Such a requirement is also made for a drawer device provided in a vehicle interior, and it is desired to reduce the abnormal noise generated when the drawer device is pulled out. The technical objective of the present invention is to reduce the noise caused by the contact between the locking pawl and the locking wall, among the various noises generated when the drawer member is pulled out.

[Means for Solving the Problems] The drawer device of the present invention includes a substantially cylindrical case and a drawer member held in the case so as to be able to freely move in and out. In a drawer device that restricts the amount of pullout of a drawer member from a case by abutting a locking wall provided on the other side, the locking wall is a through groove extending in a direction crossing the direction of movement of the locking pawl. It is characterized in that it has a flexible part which is partitioned by a latching claw and partially contacts the latching claw, and the flexing part is configured to elastically deform when the latching claw presses the flexible part.

The most distinctive feature of the present invention is that the locking wall has a through groove extending in a direction crossing the direction of movement of the locking pawl, and a flexible portion that is partitioned by the through groove and partially contacts the locking pawl. , the flexible portion is configured to be elastically deformed when the locking pawl presses the flexible portion. In other words, the elastic deformation of the flexible portion cushions the impact of contact and prevents the generation of abnormal noise. Incidentally, even if the flexible portion comes into full contact with the locking pawl, abnormal noise can be prevented to some extent if the flexible portion is elastically deformed, but the effect is very small. In the present invention, the flexible portion is configured to partially contact the locking pawl. Therefore, since the contact area is small, the noise generated during contact is also reduced. In addition, since stress acts partially on the flexible portion, it is likely to be elastically deformed. Therefore, it is possible to satisfactorily buffer the impact upon contact and to satisfactorily prevent abnormal noise. The locking pawl may be provided on the drawer member and configured to abut against the locking wall of the case, or the locking pawl may be provided on the case so that the locking wall provided on the drawer member engages with the locking pawl. It can also be configured to be stopped.

[Operations and Effects of the Invention] In the drawer device of the present invention, the locking wall has a flexible portion defined by a through groove, and the locking claw partially contacts the flexible portion. Then, after the locking pawl and the flexible part come into contact with each other due to the movement of the drawer member, the flexible part is pressed by the locking pawl and deforms elastically, so the impact at the time of contact is buffered and abnormal noises are prevented. can do. Here, since the locking pawl partially contacts the flexible part, the stress acting on the flexible part is concentrated in that part, and the flexible part can easily be elastically deformed. Since the amount of elastic deformation of the flexible portion is also increased, stress at the time of contact is buffered extremely well, and generation of abnormal noise is effectively prevented.

Therefore, according to the drawer device of the present invention, when the drawer member is pulled out and the locking pawl comes into contact with the locking wall, generation of abnormal noise is prevented and the feeling is good.

[Example] The following is a concrete explanation using Examples. In this embodiment, the drawer device of the present invention is applied to a cup holder of an automobile. This cup holder is made of resin such as polyacetal.

FIG. 1 is a perspective view of a cup holder according to an embodiment of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is an enlarged sectional view of a main part. This cup holder includes a case 1 fixed to an automobile instrument panel,
It is comprised of a holder (drawer member) 2 held in a case 1 so as to be freely removable. 2 for case 1
Two grooves 10 are formed. The holder 2 also has two locking claws 20 protruding from the groove 1.
0 is engaged. The holder 2 is moved in and out of the case 1 by the locking pawl 20 being guided by the groove 10, and the holder 2 is moved in and out of the case 1 by the locking pawl 20 coming into contact with a locking wall 11 formed at the end of the groove 10. The withdrawal amount of 2 is regulated.

Note that two holder holes 21 are bored in the holder 2, and a container such as a cup or a youth can is placed in the holder holes 21. Further, one end of a receiving member 22 is swingably held in the holder 2, and is configured to take a state where it is housed in the holder 2 and a state where it swings from the holder 2 and is located directly below the holder hole 21. . Therefore, the bottom of the container inserted into the holder hole 21 is supported by the receiving member 22.

Here, the structure of the locking pawl 20 and the locking wall 11 will be explained in detail below. As shown in plan views in FIGS. 4 and 5, three arc-shaped through grooves 12a, 12b, and 12c are formed in the portion of the case 1 that constitutes the locking wall 11. The central through hole 12b has an elongated hole shape extending perpendicularly to the moving direction of the locking pawl 20. Two through grooves 12a and 12c are formed on both sides of the central through hole 12b, with a bridge portion 12d in between and forming an angle with the moving direction of the locking pawl 20. Therefore, in the locking wall 11, two inclined bending parts 13a, 13c which are inclined with respect to the moving direction of the locking claw 20 and extend toward each other are connected to each other, and the two inclined bending parts 13a, 13c are connected. The central bending portion 13b is formed into an arcuate shape facing toward the center bending portion 13b. Note that each of the flexible portions 13a, 13b, and 13c is connected to the case 1 by a bridge 12d to maintain strength and shape.

Next, a case where the locking claw 20 and the locking wall 11 are in contact will be described. When the locking claw 20 moves in the direction of the arrow as shown in FIG. 4, the locking claw 20 moves as shown in FIG.
Both corner portions of 0 are inclined bending portions 13a, 13, respectively.
come into contact with c. Here, this contact becomes a point contact,
The force caused by pulling out the holder 2 is partially concentrated and acts on each of the inclined bending portions 13a and 13c. Due to this pressing force, the inclined bending portions 13a, 13c
is elastically deformed so as to narrow the through holes 12a and 12c, and a tensile force acts on the central flexible portion 13b. Since the central bending portion 13b has an arc shape, it is easily deformed by tensile force and is prevented from becoming an obstacle to the deformation of the inclined bending portions 13a and 13c. After that, the locking claw 20 is attached to the central flexible portion 13b.
come into contact with. The force due to the pull-out similarly acts on the central flexible portion 13b, and the central flexible portion 13b is also elastically deformed. Therefore, in the cup holder of this embodiment, when the locking pawl 20 collides with the locking wall 11, the three bending parts 13a, 13b, 13c are elastically deformed, and the amount of the bending is sufficiently large, so that the force of the collision is sufficiently buffered. This can prevent the occurrence of abnormal noise.

That is, according to the cup holder of this embodiment, the generation of abnormal noise when the holder is pulled out is reliably prevented, and the impact caused by the collision between the locking pawl and the locking wall when the holder is pulled out is also small.
