DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an inner surface of a vehicle door to which the present invention is applied.
In the figure, 10 is a cup holder device, which is provided on the upper inner surface of the door 1. As shown in FIG. 2, the cup holder device 10 includes a base plate 20, a cover 30, an arm 40, a holder 50, and the like, and these components are integrally formed of a soft resin.
[0010]
The base plate 20 is a substantially flat member, and two screw insertion holes 21 are formed on both sides of the upper end as shown in FIG. In addition, a pair of insertion portions 22 are formed downward at the bottom of the back surface of the base plate 20. These insertion portions 22 are inserted into the holes 3 (see FIG. 4) of the door trim 2 of the door 1 from above and are screwed from the front side. The base plate 20 is fixed to the door 1 in the vertical direction by screwing 4 into a nut 6 fixed to the back surface of the inner panel 5. A pair of rails 23 project vertically from the center of the front surface of the base plate 20, and vertical guide grooves 24 are formed on both outer surfaces of the rails 23. The lower end portion of the guide groove 24 opens downward, and the upper portion is inclined slightly forward 24b, and then the upper end portion opens forward. In the middle of the upper end opening 24 a of the guide groove 24, a downward regulating claw 25 that locks a regulating projection 53 of the holder 50 described later is formed. A pair of outward shaft portions 26 project from the lower end portion of the front surface of the base plate 20, and these shaft portions 26 are rotatably fitted in bearing holes 31 of a cover 30 described later. A box-shaped convex portion 27 that protrudes forward is integrally formed at the upper end portion of the rail 23. A lock button 28 is integrally formed on the upper edge of the base plate 20 so as to be elastically displaced in the vertical direction. On both sides of the lower end portion of the lock button 28, lock claws 28a that engage with claws (engagement portions) 34 of a cover 30 to be described later and hold the cover 30 in a closed state are formed.
[0011]
The cover 30 also serves as a cup bottom receiving plate, and is integrally formed with a resin so as to have a concave cross section so that the front side of the base plate 20 can be covered. A bearing hole 31 into which the shaft portion 26 of the base plate 20 is rotatably fitted is formed at one end of the cover 30, and the cover 30 has a closed position that covers the front side of the base plate 20 and a horizontal open position. It can be opened and closed. In addition, a pair of shaft support portions 32 into which one end portion of an arm 40 to be described later is fitted project from the same end portion of the cover 30. A relief portion 33 for preventing interference with the lock body 28 is formed in the other end portion of the cover 30, and the inside of the relief portion 33 is engaged with a lock claw 28 a of the lock button 28 and closed. A claw 34 for holding the state is formed. A circular shallow recess 35 that supports the bottom of the cups C is formed at the center of the cover 30.
[0012]
The arm 40 is also integrally formed of resin in a substantially U-shape, and two shaft portions 41a and 41b that are rotatably fitted to the shaft support portion 32 of the cover 30 are formed at its base end portion (one end portion). Projected to both sides. Among these, one shaft portion 41a is formed longer than the other shaft portion 41b, and a compression coil spring 48 is inserted through the long shaft portion 41a. Therefore, after the long shaft portion 41a is fitted to one bearing portion 32 and the coil spring 48 is compressed, the short shaft portion 41b is fitted to the other bearing portion 32, whereby the arm 40 is attached to the cover 30. Can be easily assembled, and the shaft portions 41a and 41b can be prevented from being detached from the bearing portion 32. Shaft portions 42 a and 42 b project inwardly at the free end portion (the other end portion) of the arm 40, and these shaft portions 42 a and 42 b are rotatably fitted in the bearing holes 51 of the holder 50. ing. One shaft portion 42a is formed longer than the other shaft portion 42b, and a torsion spring 49 that urges the arm 40 and the holder 50 in the opening direction A is inserted through the long shaft portion 42a. ing.
[0013]
The holder 50 prevents the cups C placed on the cover 30 from overturning, and is integrally formed with resin in a shape that can be folded inside the arm 40. The holder 50 of this embodiment is formed in a substantially U shape or a substantially C shape with one end opened. The opening at the tip of the holder 50 is formed to be slightly wider than the gap between the claws 34 of the cover 30. Bearing holes 51 are formed in both side portions on the free end side of the holder 50, and the shaft portion 42 of the arm 40 is rotatably fitted in these bearing holes 51. A pair of columnar slide projections 52 that slidably engage with the guide grooves 24 of the base plate 20 project inwardly at the end portion (intermediate portion) opposite to the free end side of the holder 50. Between these projections 52, a regulation projection 53 that engages with the regulation claw 25 of the base plate 20 is projected upward. The restricting claw 25 and the restricting projection 53 constitute the restricting means of the present invention, and the locking force is set to such a degree that it can be removed relatively easily when a large external force acts on the holder 50 forward.
[0014]
The cup holder device 10 having the above configuration is assembled as follows.
First, the shaft portion 26 of the base plate 20 is fitted into the bearing hole 31 of the cover 30 to connect the base plate 20 and the cover 30 so as to be rotatable. On the other hand, the holder 50 and the arm 40 are assembled in advance, and the shaft portions 41 a and 41 b of the arm 40 are fitted to the shaft support portion 32 of the cover 30. When the cover 30 is closed while the holder 50 is folded inside the arm 40, the slide protrusion 52 is automatically inserted from the lower end opening of the guide groove 24, and the assembly is completed.
In addition to the above assembly method, if the slide protrusion 52 is forcibly pushed into the upper end opening 24 a of the guide groove 24, the restriction protrusion 53 gets over the restriction claw 25, so that the slide protrusion 52 is inserted into the guide groove 24. be able to.
[0015]
Further, when it is desired to use the cup holder device 10 as an accessory case, the holder 50 and the arm 40 may be removed. First, the cover 30 is opened to the fully open position, and the shaft portions 41 a and 41 b of the arm 40 are removed from the shaft support portion 32 of the cover 30. That is, when the arm 40 is pushed toward the long shaft portion 41 a and the coil spring 48 is compressed, the short shaft portion 41 b is easily detached from the shaft support portion 32. When the slide protrusion 52 of the holder 50 is pulled out from the lower end opening of the guide groove 24, the holder 50 and the arm 40 can be easily removed.
[0016]
Next, the opening / closing operation | movement of the said cup holder apparatus 10 is demonstrated according to FIGS.
FIG. 4 shows a state in which the cover 30 is open, and the side edge 36 on the rear edge side of the cover 30 hits the lower edge of the boss portion 29 supporting the shaft portion 26 of the base plate 20 and the lower edge of the stopper projection 20a and stops. ing. Therefore, the cover 30 is supported in a horizontal position, and the cover 30 does not bend even if the weight of the cups C acts on the cover 30. Further, since the arm 40 and the holder 50 are biased in the opening direction by the torsion spring 49, the slide protrusion 52 of the holder 50 stops at the upper edge of the guide groove 24 and is substantially in a horizontal position. The arm 40 stands up at an angle of 45 degrees.
[0017]
When the cover 30 is rotated in the closing direction, the inner surface of the cover 30 comes into contact with the front end portion of the holder 50 when the cover 30 is rotated about 45 degrees, and the front end portion of the holder 50 is pushed up obliquely rearward. Therefore, the rear end portion (base plate side) of the holder 50 is pushed down and guided downward using the inclined portion 23 b of the guide groove 24, and the slide protrusion 52 slides downward along the guide groove 24. Along with this, the arm 40 also rotates upward. FIG. 5 shows this state.
[0018]
When the cover 30 is further rotated in the closing direction to reach the fully closed position, the claw 34 of the cover 30 engages with the lock claw 28a of the lock button 28, and the cover 30 is held in the closed state. At this time, the holder 50 is folded inside the arm 40, and the holder 50 and the arm 40 are compactly stored between the base plate 20 and the cover 30. FIG. 6 shows this state.
[0019]
On the other hand, when opening the cover 30 in the fully closed position, the lock button 28 exposed on the top surface of the cover 30 is pushed down. As a result, the front end side of the lock button 28 is displaced downward, and the lock claw 28 a is detached from the claw 34 of the cover 30. Therefore, the upper end of the arm 40 tries to rotate forward by the torsion spring 49 and pushes the cover 30 in the opening direction. When the cover 30 rotates in the opening direction, the arm 40 also follows and rotates, and the slide protrusion 52 of the holder 50 slides upward in the guide groove 24. Then, when the holder 50 is rotated to a substantially horizontal position, the slide protrusion 52 comes into contact with the upper end of the guide groove 24 and stops, and thereafter, only the cover 30 is rotated to the horizontal position.
[0020]
In the cup holder device, when the cups C are placed on the cover 30 with the cover 30 opened to the horizontal position, the outer periphery of the cups C is held by the holder 50. In particular, since the holder 50 is supported from both sides by the arm 40, the base plate 20, the holder 50, and the arm 40 have a triangular structure in a side view as shown in FIG. 4 and a very stable support structure. Therefore, the cups C can be stably held without the holder 50 being bent or rattling even when vehicle body vibration or inertial force is applied.
Further, when the cover 30 is opened, the arm 40 rotates in the same direction as the cover 30. Therefore, the cover 30 and the arm 30 rotate smoothly just by releasing the lock of the cover 30, and interlocked with this. The holder 50 also smoothly rotates to the horizontal position. Further, since the holder 50, the arm 40, and the cover 30 can be urged in the opening direction only by the spring 49 that urges the holder 50 and the arm 40 in the opening direction, the number of parts is small and the structure becomes very simple.
[0021]
By the way, in the case of the cup holder device as described above, when an external force is applied to the holder 50 in a state where the cover 30 is in the fully open position and the cups C are not held, the slide protrusion 52, the shaft portions 41a and 41b, The shaft portions 42a and 42b are easily damaged. If it is attempted to reinforce such protrusions and shafts so as not to be easily damaged, the cup holder device as a whole becomes large.
Therefore, in the above embodiment, when an external force is applied to the holder 50, the slide protrusion 52 of the holder 50 is detached from the guide groove 24 to prevent the protrusion and the shaft portion from being damaged. That is, in FIG. 4, when a pressing force F ₁ or a forward pulling force F ₂ of a certain value or more acts on the holder 50, the restricting projection 53 of the holder 50 is disengaged from the restricting claw 25 of the base plate 20 and the slide protrusion 52 is guided. The groove 24 moves forward from the upper end opening 24a (indicated by a two-dot chain line in FIG. 4). Therefore, an excessive force does not act on the slide protrusion 52 and the shaft portions 41a, 41b, 42a, 42b, and the breakage can be prevented.
When reassembling, the slide protrusion 52 is automatically inserted from the lower end opening of the guide groove 24 if the cover 30 is closed while the holder 50 is folded inward of the arm 40 as described in the above assembly method. Can be assembled easily.
[0022]
Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made as described below.
FIG. 7 shows another embodiment of the restricting means.
In this embodiment, a projection 24c projecting inward is formed in the upper end opening 24a of the guide groove 24 so that the slide projection 52 does not come out freely from the upper end opening 24a. Also in this case, when a forward external force is applied to the holder 50, the slide protrusion 52 comes out from between the protrusions 24c, so that an excessive load is not applied to the holder 50 and the arm 40.
[0023]
In the above embodiment, the arm 40 is formed in a substantially U shape so that both sides of the holder 50 can be pivotally supported. However, the arm may be constituted by two link members. In short, the shape is not limited as long as it does not interfere with the cups placed on the cover and can be folded together with the holder inside the cover. In addition, when the arm is substantially U-shaped, there is an advantage that the right and left inclination of the holder can be restricted and the support rigidity is increased.
[0024]
Further, although the arm 40 is pivotally supported on the pivotal support portion 32 of the cover 30 so as to be rotatable in the vertical direction, it may be pivotally supported on the base plate 20 instead of the cover 30. Further, the arm may be pivotally supported on the same axis as that of the cover.
[0025]
In the above embodiment, the lock button 28 is integrally formed on the base plate 20 as the lock portion. However, the lock button may be formed on the cover 30, and a separate lock button may be attached to the base plate 20 or the cover 30. . When the lock claws 28a are formed on both sides of the lock button 28 as in the embodiment, an upper push type and thin cup holder device can be obtained.
[0026]
When holding a large cup, it may not be possible to hold the slide 50 in a state where the slide protrusion 52 of the holder 50 is engaged with the guide groove 24. On the other hand, when the slide protrusion 52 is removed from the guide groove 24, the arm 40 is rotated to the horizontal position, so that a force in the falling direction is applied to the cup. Therefore, instead of the coil spring 48, a torsion spring may be inserted into the shaft portion 41a of the arm 40, so that the arm 40 is constantly given upward turning power. In this case, since the holder 50 and the arm 40 are lifted upward by the torsion spring, the cup can be prevented from overturning.
[0027]
Note that the vehicle cup holder device of the present invention is not limited to the inside of the door, but can be employed in any part such as the back of the seat or the inside of the vehicle body.
[0028]
【The invention's effect】
As is clear from the above description, according to the present invention, the lock button is a push method from above, so that the operation is simple and the lock button is formed integrally with the base plate, so the number of parts is small. That's it. In addition, since lock claws are formed on both sides of the lock button, it is only necessary to form an engagement portion of the cover that engages with the lock claw on a portion facing both sides of the lock button, and thus the thickness of the cover. The cup holder device can be thinned as a whole.
