Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the structure for attaching a push bar used to automatically push out a drawer body from the inside of a housing in various drawer devices for automobiles having a so-called push-open function.

[0002]

[Prior art]

 This type of drawer device having a push-open function usually includes at least a housing that is fixed to the vehicle body side, a drawer body that is movably supported in the housing, and a push spring that pushes the drawer body out of the housing. And a locking means for locking the drawer body in the housing against the biasing spring pressure of the push spring, and pushing the drawer body locked in the housing slightly inward to lock the drawer body When the locked state by the means is released, the drawer body can be automatically pushed out of the housing by the biasing spring pressure of the push spring. In the prior art, when a compression coil spring is used as the above-mentioned push spring, for example, as shown in Japanese Utility Model Laid-Open No. 2-59039, a bifurcated protrusion having a retaining projection on the rear wall side of the housing is used. The shaft portion is integrally projected, and a compression coil spring is attached to the outer periphery of the bifurcated shaft portion.

[0003]

[Problems to be solved by the device]

 However, at first glance, it seems that the conventional structure for mounting a compression coil spring is simple and extremely rational, but in reality, the compression coil spring is mounted on a bifurcated shaft. In this case, since the shaft portion has a retaining protrusion that bulges outward, the compression coil springs must be mounted one by one while overcoming the retaining protrusion. There was a big problem that the work of installing the barrel compression coil spring was extremely difficult. Moreover, particularly in the case of the drawer device for automobiles, the installation space is naturally limited, and from this point as well, it is difficult to repeat the above-mentioned small and complicated work. It will be further encouraged.

[0004]

[Means for Solving the Problems]

 The present invention was developed in order to effectively solve such a conventional problem, and uses a compression coil spring as a push spring that automatically pushes the drawer body to the outside of the housing. Assuming a mounting structure to be attached to a predetermined part of the drawing device, a cylindrical case body in which the front end side of the compression coil spring is fitted into the inside from a rear end opening, and the cylindrical case body can be moved back and forth through a guide hole. The tubular case body has a retaining frame at the rear end opening edge of the guide hole, and the retaining frame is provided with a guide frame for retaining the guide frame. We adopted a structure with a support shaft that fits the rear end of the spring.

[0005]

[Action]

 Therefore, under the mounting structure of the present invention, the guide frame is attached to the predetermined portion side of the drawing device in advance without the need to repeat the detailed and complicated work as in the conventional case, and thereafter While obtaining the state in which the front end side of the compression coil spring is fitted into the inside of the cylindrical case body from the rear end opening, while fitting the rear end side of the compression coil spring from the guide hole to the support shaft of the guide frame, Only by forcibly inserting the tubular case into the guide frame, the slip-out prevention claws pass through the guide hole while bending inward and engage with the hole edge of the guide hole from the inside. As a result, the tubular case body is held so as to be able to move forward and backward without coming off the guide frame, and at the same time, the compression coil spring itself is immediately attached to the predetermined portion as it is.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail with reference to one embodiment shown in the drawings. In the push spring mounting structure according to the embodiment, a compression coil spring used as a push spring is used at a predetermined portion of a drawing device as in the conventional structure. In this embodiment, the basic structure of the cup holder device will be described first because it is intended for a semi-automatic cup holder device for an automobile.

That is, as shown in FIGS. 1 and 2, the target cup holder device includes a box-shaped housing 1 that is inclined and fixed to an instrument panel (not shown) side, and a holding hole 3 for the cup. A holder main body 2 that is opened and supported so as to be drawn out in the housing 1 is provided, and a receiving body 4 that is pivotally attached to the holder main body 2 and supports the bottom portion of the cup.

With respect to the holder main body 2, a concave step portion 5 communicating with the holding hole 3 is individually formed at an edge portion of each holding hole 3 formed on the front end side near the rear end, and each concave step is formed. The pressing arm 6 urged in the portion 5 by the spring pressure of the torsion spring 7 to be always rotated upward is rotatably supported by the shaft 8 and the bearing 9, and in particular, each pressing arm is supported. The side surface of the cup is elastically sandwiched between the tip end of 6 and the corresponding hole edge of the holding hole 3, while it is engaged with and disengaged from the cam groove of a cam member which will be described later at the center of the rear end side upper surface. The pin 10 is erected, and one stopper claw 11 and two elastic claws 12 are integrally formed on the lower surface on the rear end side.

Further, in particular, as is apparent from FIG. 2, with respect to the housing 1, a cam member 13 is provided at the center of the rear end side of the inner surface of the upper wall so as to be pivotable via biasing spring pressure, while having a narrow width. A restricting portion 14 with which the stopper claw 11 abuts is formed in the center of the bottom wall, and a pair of hole parts 15 are provided on both sides of the restricting portion 14 for locking the two elastic claws 12 with a feeling of moderation. Is configured to open.

In addition to the structure of the housing 1 in the present embodiment, as shown in FIG. 3, the cam member 13 on the inner surface of the rear end side upper wall of the housing 1 is provided on both sides of the cam member 13. A pair of rectangular guide frames 16 for holding a cylindrical case body 19 described later so as to be movable back and forth are integrally provided, and a guide hole 17 having a cross-sectional shape similar to that of the cylindrical case body 19 is provided on the front surface thereof. And a support shaft 18 that extends along the approximate center line of the guide hole 17 and fits the rear end side of the compression coil spring S, which is a pressing spring, is laterally provided integrally with the rear surface of the guide hole 17. I am doing it. Further, the cylindrical case body 19 held by each of the guide frames 16 is an integrally molded product made of synthetic resin, and as shown in FIG. 4, only the rear end is opened and the front end portion of the compression coil spring S is internally formed. A cylindrical portion 19a into which the side is fitted, a plate-like portion 19b that is connected to the cylindrical portion 19a and slides on the upper wall surface of the housing 1, and a plate-like portion 19b that is continuous from the rear end opening edge side of the cylindrical portion 19a. It is configured to have a pair of slip-off prevention claws 20 that are formed as described above and have an anchor shape.

Therefore, when the compression coil spring S, which is a pressing spring, is attached to the housing 1 side under such an attachment structure, the front end side of the compression coil spring S is inside the cylindrical portion 19a of the cylindrical case body 19. And the rear end side of the compression coil spring S is externally fitted to the support shaft 18 through the guide hole 17, and the tubular case body 19 is inserted into the guide frame 16 from the slip-off prevention claw 20 side. By simply forcibly inserting it into the guide hole 17, the pair of slip-out preventing claws 20 bends inward and pass through the guide hole 17 and are locked from the inside to the hole edge of the guide hole 17. The case body 19 is held in the guide frame 16 so as to be able to move forward and backward without coming off, and at the same time, the compression coil spring S itself is immediately attached to the housing 1 side.

Therefore, in actual use, the holder body 2 is slightly pushed into the housing 1 and the pin 10 is removed from the cam groove of the cam member 13, as shown in FIG. As described above, the pair of cylindrical case bodies 19 are moved forward in the guide frame 16 by the biasing spring pressure caused by the extension of each compression coil spring S until they are locked to the edge of the guide hole 17 of the slip-out preventing claw 20. Since the holder main body 2 is automatically pushed out from the inside of the housing 1 to the middle thereof, the front plate portion 2a of the holder main body 2 is gripped and the holder main body 2 is stopped by the stopper claws 11 though not specifically shown. If the retainer arm 6 rotates upwards while the holder 4 is rotated to the upper limit, the receiver 4 rotates downward due to its own weight, and the cup can be held securely in the holding hole 3. It will be possible.

On the contrary, when the holder main body 2 pulled out outward is pushed into the housing 1, the elastic claw 12 is disengaged from the hole 15 described above, and this time the holding arm 6 is opened at the upper edge of the opening of the housing 1. At the same time, the receiving body 4 is pressed downward by the housing 1 to be housed in the recessed step portion 5 thereof, and at the same time, the receiving body 4 is also pressed by the lower edge of the opening of the housing 1 and is folded in parallel with the lower surface side of the holder body 2. If the holder body 2 is completely pushed into the housing 1 against the spring pressure of the pair of compression coil springs S as it is, then, as shown in FIG. Since the case body 19 retracts in the guide frame 16 while contracting the compression coil spring S, the pin 10 is then locked in the cam groove of the cam member 13 so that the holder main body 2 is placed in the housing 1. By locking it, its unused condition The situation will be easily obtained.

According to the present embodiment, even when the compression coil spring S contracts through the tubular case body 19 when the holder body 2 is pushed in, conversely, when the holder body 2 is pushed out, Even when the compression coil spring S extends through the tubular case body 19, the expansion and contraction of each compression coil spring S is guided within the inner surface of the cylindrical portion 19a of the tubular case body 19 and the outer surface of the support shaft 18. Therefore, even if a long compression coil spring S is used, there is no concern that the compression coil spring S will buckle during its expansion and contraction and its original function will not be exerted.

Further, in the above embodiment, the guide frame 16 for holding the tubular case body 19 is provided on the rear end side of the housing 1, but the present invention is not limited to this. Even if the guide frame 16 is provided on the rear end side of the holder main body 2 in the opposite direction, the same operational effect can be expected, and in the embodiment, the guide panel 16 is installed on the instrument panel side with an inclination. It is intended for semi-automatic cup holder devices, but the push-spring mounting structure of the present invention is also applicable to ashtray devices and small objects, including fully automatic cup holder devices installed horizontally. It goes without saying that the present invention can be easily implemented and applied to other vehicle drawer devices having a push-open function, such as an insertion device.

[0016]

[Effect of device]

 As described above, according to the present invention, by adopting the above-mentioned configuration, a cylindrical case body having a compression coil spring as a push spring fitted therein can be simply installed without the need for repeatedly performing the complicated and complicated work. Since the compression coil spring can be attached to a predetermined portion of the drawing device extremely simply and reliably by simply inserting the compression coil spring into the guide frame from the direction, the improvement of the attachment work can be greatly expected. In addition, when the compression coil spring expands and contracts, the guiding action of the inner surface of the cylindrical case body and the outer surface of the support shaft is always obtained, so there is no risk of the compression coil spring inadvertently buckling. There is also an advantage that the pushing stroke of the drawer body can be freely determined by appropriately selecting the dimensions of the cylindrical case body.
