Description

[Detailed Description of the Invention] This invention is designed to smoothly flip up the lid of a console box of a car by controlling the inertia of the lid caused by flipping up the lid of a console box using the other coil spring. The console is characterized in that one coil spring applies a springing force to the lid to open the lid of the console box, and as the lid is opened, the other weaker coil spring applies a force in the direction of closing the lid. This relates to a box lid opening/closing device.

The conventional console box lid opening/closing device has a console box lid arm 22 and a main body arm 27 at both ends, respectively, as shown in FIGS. 11 and 12. A shaft 29 is provided between the arm 27 and coil springs 32 and 33 which are wound around the outer periphery of each shaft 29 to give elastic force, and the ends on both sides of the coil springs 32 and 33 are covered. This conventional opening/closing device is a device in which the center end of the coil springs 32 and 33 is locked to the arm 27 of the main body or the connecting part between the main body and the arms of the main body. In order to open the lid of a large console box with a large console box attached, the initial spring force must be large, for example, about 200mm in height and 150mm in width.
2 coil springs 3 because I could not open a large console box with a height of about 20 mm.
2 and 33 act simultaneously as shown by the arrows, a considerably strong force is applied to the lid 36, and it springs up at a high speed, but the lid of the console box remains open at a high speed until the end, so it is not safe for the user. This may create a sense of danger, or it may require a strong and relatively heavy stopper to stop the console box lid that has been pushed all the way up.
Even if the console box hits the stopper, the lid bounces back a lot, and the lid of the console box strongly hits the stopper, producing an unpleasant sound. Furthermore, when the lid of the console box is closed, the elastic force remaining in the two coil springs 32 and 33 and the force that tightens the two coil springs 32 and 33 to impart elastic force to the two coil springs are combined. This has the disadvantage that the lid of the console box must be closed with considerable force. These shortcomings are due to the fact that
No. 66266 (Utility Model Publication No. 154713) and Utility Application No. 154713
-98220 (Utility Model Application Publication No. 57-22979) described in the respective specifications and drawings are also included.

In view of these drawbacks of conventional console box lids, this invention aims to control (brake and slow down) the inertia of the console box lid caused by flipping it up using the other coil spring. As a result, the flip-up speed of the lid is suddenly slowed down to smoothly open the lid, and at the same time, the elastic force in the direction of closing the lid is accumulated in the other coil spring, and this elastic force is accumulated in the other coil spring. The purpose is to be able to close the lid with a fairly small amount of force due to the elastic force.

Next, an embodiment of the console box lid opening/closing device of the present invention will be described.

Arms 2 are provided at both ends of a lid plate 1, and a shaft hole 3, a stopper hole 4, and a coil spring hole 5 are provided in the arms 2 at both ends, respectively.

Two arms 7 are provided at both ends of the main body plate 6,
Shaft holes 8 are provided at the tips of the arms 7 at both ends.

One end of the lid plate 1 and the main body plate 6 is inserted into the outer periphery of the shaft 9 by passing the shaft 9 through the shaft hole of the arm 7 provided in the main body plate 6 as shown (the left end in FIG. 4). After installing a coil spring 12 in the arm 7, the shaft 9 is passed through the other shaft hole 8 of the arm 7. And the washers 10 on the axis 9
After passing the shaft 9 through the shaft hole 3 of the arm 2 provided in the lid plate 1, attach both ends of the shaft 9 to a C-shaped stopper (E
Ring) Stop at 11. From the free state ₁₂₃ , the coil spring 12 is wound tightly as shown by the dotted line _arrow in _FIG . The coil spring 12 is pressed against the arm 2 by elastic force, and the central end 12 ₂ of the coil spring 12 is pressed against the arm 7 of the main body plate 6 by elastic force to be locked. Then, insert the center twist screw 14 into the stopper hole 4 provided in the arm 2 of the lid plate 1, and attach the stopper 1 to the outside of the arm 2.
5 will be provided.

The other end of the lid plate 1 and the main body plate 6 has a structure assembled in almost the same manner as the one end described above, but to explain the difference, the coil spring 13 at the other end is assembled as shown in FIG. One coil spring 1 as shown
The elastic force is generated in the opposite direction to the coil spring 12 at the other end, and the force is smaller than that of the coil spring 12 at the other end.
3 inserts and locks the outer end ₁₃₁ of the coil spring 13 at the other end in a free state without applying elastic force to the coil spring hole 5 provided in the arm 2 of the lid plate 1. This is the point.

This lid opening/closing device has the lid plate 1 screwed to the lid 16 and the main body plate 6 screwed to the main body 17. Note that reference numeral 18 is a lock fitting attached to the lid 16. Further, in this embodiment, the outer end 12 ₁ of one coil spring 12 is pressed against the arm 2 of the lid plate 1 by elastic force and locked, but the outer end 12 ₁ may be inserted into the coil spring hole 5 and locked.

To explain the operation of the lid opening/closing device of the console box of this embodiment, when the locking fitting 18 of the lid 16 is removed with a human fingertip, the arm 2 of the lid plate 1 moves the shaft 9 with the elastic force of the coil spring 12. Rotate the lid 1 as a fulcrum point as shown by the arrow in Figure 3.
6 is opened, the other coil spring 13 is gradually tightened as the lid 16 is opened, and generates an elastic force in the direction of closing the lid 16.

The lid 16 is gradually opened until the stopper 15 provided on the arm 2 of the lid plate 1 hits the main body 17 as shown in FIG. 6, and the lid 16 is stopped by the stopper 15.

This lid 16 changes from a closed state (horizontal state) to a fully open state (rotated approximately 90 degrees and approximately vertical state)
The elastic force of both coil springs 12 and 13 up to this point is shown in the graph of FIG. The elastic force is zero, and as the lid is opened, the elastic force of the coil spring 12 gradually decreases, and when the lid is completely opened, the elastic force becomes small as a. The other coil spring 13 is gradually tightened in the opposite direction from zero, and a negative elastic force is gradually generated in the direction of opening the lid 16, that is, an elastic force in the direction of closing the lid 16, and the lid is closed. When fully opened, the negative elastic force is b (however, a≧b).

When the elastic forces of both coil springs 12 and 13 are combined, the lid 16 is combined as shown by the solid line in the graph of FIG.
When opening, the elastic force is large as A, but as it opens, the other coil spring 13 changes from the free state 13 ₁ to the state 13 ₃ where it is tightened as shown by the dotted line arrow in Figure 7 and gives an elastic force. The elastic force to open the lid 16 is significantly reduced, and when it is fully opened, a
-b, which is extremely small.

This time, when closing the lid 16, the other coil spring 13 has an elastic force (minus elastic force -b) in the closing direction (as indicated by the solid line arrow in Fig. 7), so when the lid 16 begins to close, it is approximately a. It is possible to start closing the lid 16 with an extremely small force of −b. When the lid 16 is closed, the other coil spring 13 is tightened.
is released and returns to the original free state ₁₃₁ , and one of the coil springs 12 is tightly wound to return to its original state with elasticity. This lid 16 is locked with a lock fitting 18.

The coil spring 13' shown in FIG. 9 uses another coil spring as the other coil spring, and this other coil spring 13' has its outer end 13' ₁ set as a dotted line from when it is free 13' ₄ . It is unwound as shown by the arrow in the released state, and then inserted into the hole for the coil spring provided in the arm of the lid plate as in the previous embodiment and locked therein.

This other coil spring 13' has a force (1
3' ₁ to 13' ₄ ), so one coil spring similar to that of the previous embodiment is used, and when opening the lid, the other coil spring 1 is initially activated.
3' adds the opening force of one coil spring.

While the lid of the console box is opened, the other coil spring 13' is tightened from 13' ₄ to 13' ₃ , giving it elastic force.
The elastic force of the other coil spring to open the lid is significantly reduced, and the lid gradually opens.

A graph of the elastic force of both coil springs is shown in Figure 10, and when the lid is opened, the elastic force is C.
+D is large, but as the lid opens, the elastic force of one coil spring itself decreases, and the other coil spring is gradually tightened, creating a negative elastic force, so when the lid is completely opened, Only an extremely small force of c-d is applied. (However, c≧d) Next time, when closing the lid, the other coil spring 13' has an elastic force (minus elastic force - d) in the direction of closing from 13' ₃ to 13' ₄ , so it begins to close. can start closing the lid with an extremely small force of approximately c-d. When the console box lid is closed, both coil springs return to their original state.

The console box lid opening/closing device of the present invention includes one coil spring that provides the action of opening the console box lid by elastic force, and at least the one coil spring that acts when the console box lid is opened. By installing the other coil spring that can apply elastic force in the opposite direction, the elastic force generated when opening the lid is rapidly absorbed by the other coil spring, and the force suddenly decreases, as if applying a brake. The flip-up speed of the lid of the console box when it is opened is suddenly slowed down, so there is no danger to the user, and the lid of the console box does not collide strongly with the stopper, resulting in almost no unpleasant noise. The lid can be opened smoothly, and the elastic force absorbed by the other coil spring can be stored in the other coil spring as an elastic force in the direction of closing the console box lid. Since the elastic force for opening is absorbed and stored in the other coil spring, there is no need to use a very strong and heavy stopper to stop the console box lid that has sprung up. Even if the lid of the console box hits the lid, it is possible to almost eliminate the splashing of the lid and the unpleasant sound.

Furthermore, the console box lid opening/closing device of the present invention not only rapidly reduces the elastic force in the direction of opening the lid, but also uses this elastic force to apply elastic force to the other coil spring in the direction of closing the lid. Since this builds up and becomes like applying a brake, the lid can be closed with a considerably small force due to the accumulated elastic force of the other coil spring in the direction of closing the lid.
