Description

  The present invention relates to an opening / closing mechanism for operating a lid for opening / closing an opening in an in-vehicle interior product and various devices.

Generally, automobiles are provided with various storage units such as a center console as well as cup holders and ashtrays as interior parts. A lid is usually attached to these storage units, and an opening / closing mechanism that can be opened or closed manually or semi-automatically is used.
As shown in FIG. 7, as a conventional opening / closing mechanism 50, a pin 53 is inserted into an arm 54 provided on a lid 51, and the lid 51 is attached to a frame 52 that is fixed to the storage portion using the pin 53 as an opening / closing axis. Is configured to be openable and closable (see, for example, Patent Document 1).
JP 2003-118467 A

However, since the conventional opening / closing mechanism 50 is a uniaxial opening / closing mechanism 50 in which the lid body 51 rotates about the pin 53 as an opening / closing axis, the locus of the front and rear ends of the lid body 51 during the opening / closing operation is centered on the pin 53. Drawn in. At this time, since the protruding amount of the front and rear end portions of the lid 51, so-called “rotation widths A and B (A backward from the frame 52, B upward)” is large, the lid 51 is opened from the closed position. In order to move the lid 51 to the maximum, the lid 51 must be installed in consideration of the rotation widths A and B, so that a large dead space is formed, resulting in a problem that the storage volume must be reduced.
In addition, when the occupant puts in and out of the container during traveling, the end of the lid body in the open position protrudes upward from the opening surface of the frame 52, so that the object is caught on the protruding portion. There is.

  Therefore, the present invention aims to simplify the mechanism, reduce the dead space by suppressing the rotation width of the lid during opening / closing operation, and reduce the end of the lid from the opening surface of the frame at the open position. An open / close mechanism capable of suppressing upward protrusion is provided.

In order to solve the above-mentioned problem, the invention described in claim 1 covers a frame having an upper opening, covers the upper opening of the frame in a closed position, and is close to the back of the frame in an open position. In an opening / closing mechanism provided with a lid, the lid is provided between the frame and the lid, and allows the lid to move downward to open and allow the lid to protrude rearward. The first restricting means to be restrained, and provided between the frame and the lid body, allows the forward movement of the lid body that opens through the first restricting means, and projects upward. And a second restricting means for urging the lid to move downward is provided.
With this configuration, when the lid body rotates with respect to the frame, the first restricting means allows the lid body to move downward, and prevents the lid body from protruding backward, It is possible to allow the lid body to move in the forward direction by the two restricting means, suppress upward protrusion of the lid body, and promote the downward movement of the lid body.

According to a second aspect of the present invention, the first regulating means is provided with a first pin that is a rear portion of the lid body and serves as an opening / closing axis of the lid body, and a first guide along a vertical direction on a side wall of the frame. And the first pin is locked to the first guide portion to support the lid so that it can be opened and closed. The second restricting means includes the frame and the lid. A second pin is provided on one side of the body in parallel with the first pin, and a second guide part for guiding the second pin is formed on the other side, and the second pin is locked to the second guide part. The frame is supported to be openable and closable.
By comprising in this way, while the 1st guide part restricts the movement to the front-back direction of a cover body via a 1st pin, the movement control to the upward direction of a cover body by a 2nd guide part and a 2nd pin Corresponding to the above, the downward movement of the lid can be allowed.

According to a third aspect of the present invention, the frame and the lid are connected by an elastic member, and the elastic member is elastic until the reversal point is reached when the lid is displaced from the closed position to the open position and from the open position to the closed position. The elastic body is deformed and then elastically returned by passing through the reversal point, and the lid is held in the open position or the closed position by the elastic return force.
With this configuration, the lid body is held in the open position and the closed position by the elastic force in the open position and the closed position, and an elastic member is used when the lid body is moved from the closed position to the open direction or from the open position to the close direction. However, when the lid passes through the reversal point, the elastic return force causes the elastic body to move semi-automatically to the open position and the closed position without using a complicated mechanism or electrical means.

According to the first aspect of the present invention, when the lid is opened and closed, the rotation width can be suppressed, and the protrusion of the lid end portion upward and backward can be suppressed. The dead space to be formed can be reduced to increase the frame volume, and the storage space can be increased.
In addition, since the first restricting means can guide the lid to the lower side and suppress the protrusion of the end of the lid from the opening surface of the frame in the open position, it is possible to easily put in and out the object. .

  According to the second aspect of the present invention, the amount of protrusion above and behind the lid end during the opening / closing operation can be suppressed without requiring a complicated mechanism, so that the mechanism can be simplified. Cost can be reduced.

  According to the invention described in claim 3, when the lid is moved from the closed position to the open direction or from the open position to the close direction, an elastic force is applied by the elastic member. When it passes, the elastic return force moves semi-automatically to the open position and the closed position without using a complicated mechanism or electrical means, so that the operability of the opening / closing operation by the occupant can be improved.

Next, embodiments of the present invention will be described with reference to the drawings.
In the following description, FR indicates the front, LH indicates the left side, and UP indicates the upper side.

  As shown in FIGS. 3 and 4, the casing 5 includes a bottom wall 41. On each side of the bottom wall 41, bent portions 42 bent upward are formed. The bent portion 42 of the bottom wall 41 is fixed with a front wall 7 at the front and a rear wall 8 at the rear by rivets. On both sides of the front wall 7, bent portions 9 that are bent backward in an L shape are formed, and on both sides of the rear wall 8, bent portions 10 that are bent forward in an L shape are formed. And the side wall 11 is being fixed to each bending part 9,10,42 by the rivet, respectively. In addition, the rear wall 8 is formed lower than the front wall 7, the corner part of the rear part of the side wall 11 is cut, and the inclined part 14 is formed here. In addition, two holes 12 and 13 are formed in the front wall 7 and the rear wall 8 to reduce weight.

  Here, the side wall 11 of the casing 5 is formed with a circular boss portion 15 that bulges outward near the inclined portion 14. The center of the boss portion 15 is perpendicular to the side wall 11 toward the outside. A second pin 16 is implanted.

  A second bracket 19 is fixed on both sides of the rear portion of the lid 3 by rivets via joints 20. In the closed position, the second bracket 19 is an L-shaped member having a front portion extending downward and a rear portion extending rearward.

  At the rear part of the second bracket 19, a first pin 17 that is an opening and closing shaft of the lid 3 is planted perpendicularly to the second bracket 19 toward the outside. A second guide 21 (second guide portion) is formed at the front portion of the second bracket 19. The second guide 21 is a long hole having a substantially oval cross section for receiving the second pin 16 of the boss portion 15 described above, and is inclined upward toward the rear portion.

Here, the second restricting means 27 is configured by the second pin 16 and the second guide 21 described above.
The second restricting means 27 locks the second pin 16 provided on the side wall 11 of the frame 2 to the second guide 21 formed on the second bracket 19 of the lid 3, and the second guide 21 Corresponding to the opening / closing operation of the lid 3, it is configured to be movable in the front-rear direction with respect to the second pin.

  As shown in FIGS. 1 and 2, the side wall 11 of the casing 5 is provided with a first bracket 6 so as to cover it from the outside. The first bracket 6 and the casing 5 described above constitute the frame 2. ing. The first bracket 6 includes a flange portion 22a that is bent inwardly in a L-shaped cross section at the front edge, and a flange portion 22b that is bent inwardly in a L-shaped cross section at the lower edge, and the flange portions 22a and 22b The rivet is fixed to the side wall 11 of the casing 5. At this time, a gap 23 is formed between the outer surface of the side wall 11 of the casing 5 and the inner surface of the first bracket 6 so that the second bracket 19 of the lid body 3 is accommodated in the gap 23. It is configured. The first bracket 6 has an upper portion and a rear portion that are larger than the side wall 11 of the casing 5.

  A long hole 39 is formed in the rear part of the first bracket 6 in the vertical (vertical) direction, and guides the movement of the first pin 17 in the vertical direction when the lid 3 is opened and closed. ing. A guide rail 24 is attached to the outer surface of the first bracket 6 corresponding to the long hole 39. The long holes 39 and the guide rail 24 constitute a first guide 25 (first guide portion). The first bracket 6 is provided with holes 12a and 13a for reducing weight in the vertical direction.

Here, the first restricting means 26 is constituted by the first pin 17 and the first guide 25 described above.
In the first restricting means 26, the first pin 17 provided on the second bracket 19 of the lid 3 is engaged with the first guide 25 provided on the first bracket 6, and the lid 3 is opened and closed. Correspondingly, the first pin is configured to be movable in the vertical direction along the first guide 25. The first restricting means 26 and the second restricting means 27 described above constitute the opening / closing mechanism 4.

  Further, a connecting pin 28 is provided in the center of the first bracket 6 in parallel with the first pin 17, and the connecting pin 28 and the first pin 17 are connected by a torsion spring 29 (elastic member).

Next, the operation of the opening / closing mechanism 4 will be described with reference to FIG.
First, in the state shown in FIG. 5A, that is, in the state where the lid 3 is in the closed position covering the upper opening 40 of the frame 2, the first pin 17 is located at the upper end of the first guide 25, The two guides 21 are inclined toward the rear upper part, and support the second pin 16 on the lower end side located below. Further, the torsion spring 29 that connects the lid 3 and the frame 2 is in a state in which almost no force is applied (non-compressed state).

Here, when the rear portion of the lid 3 is pressed, the lid 3 starts to rotate with respect to the frame 2 as shown in FIG. First, the first restricting means 26 allows only the downward movement of the lid 3 when the lid 3 is opened, and the first pin 17 is guided by the first guide 25 and descends. At this time, the second restricting means 27 allows the movement of the lid 3 only in the forward direction when the lid 3 is opened, so that the rearward movement of the first pin 17 is regulated. The guide 21 moves forward with respect to the second pin 16. That is, the first pin 17 approaches the second pin 16 in the front-rear direction, and the lid 3 moves forward with respect to the frame 2, so that the rear portion of the lid 3 can be prevented from protruding. Since the second pin 16 regulates the upward movement of the lid body 3 by the second guide 21, the opening operation of the lid body 3 is smoothly performed while urging the first pin 17 to move downward. Is called.
Further, since the distance between the first pin 17 and the connecting pin 28 is also close, the torsion spring 29 is bent and elastically deformed inward.

Next, the lid 3 is in the neutral position (reversal point) between the open position and the closed position, that is, the first pin 17 reaches the rear in the horizontal direction of the connecting pin 28 (FIGS. 5B and 5C). Position between)). At this time, the first pin 17 is relatively closest to the second pin 16, the second guide 21 is parallel to the horizontal plane, and the second pin 16 is positioned on the upper end side in the second guide 21. At this position, the torsion spring 29 is in a state in which the most force is applied (the most compressed state). And if it passes through this neutral position, the 1st pin 17 and the 2nd pin 16 will be spaced apart relatively. That is, the second restricting means 27 allows only the rearward movement of the lid 3 so that the second pin 16 returns to the lower end side of the second guide 21 supporting the second pin 16 on the upper end side. Therefore, the first pin 17 is urged to move downward along the first guide 25, and the lid 3 is opened.
Further, this neutral position becomes the reversal point of the torsion spring 29, and when this reversal point is exceeded, an elastic return force of the torsion spring 29 is generated. The lid 3 that has passed through the neutral position is automatically rotated to the open position without requiring a pressing force by the elastic return force (see FIG. 5C).

  As shown in FIG. 5 (d), when the lid 3 is in the open position, the first pin 17 is lowered to the lower end of the first guide 25, so that the end of the lid 3 at the open position is moved upward. Protrusion can be minimized. The lid 3 is located behind the rear wall 8 of the frame 2 so that the amount of rearward protrusion can be minimized. At this time, the torsion spring 29 that connects the lid 3 and the frame 2 is in a state in which almost no force is applied (non-compressed state).

Moreover, in order to return to the closed position as shown to Fig.5 (a) from the state in the open position shown in FIG.5 (d), the upper part of the cover body 3 in an open position is pressed ahead. Then, the lid 3 is brought into a closed position by an action opposite to the action described above. In the closing operation, as in the opening operation, the torsion spring 29 is initially elastically deformed in response to the movement of the lid 3, and after passing through the neutral position, moves to the closed position semi-automatically by the elastic return force. To do.
Here, in FIG. 6, the locus drawn by the front and rear end portions of the lid body 3 in the opening / closing operation is drawn as the protruding amount from the surface of the lid body 3 at the open position and the closed position, and this is the rotation width that is the backward protruding amount. a and a rotation width b which is an upward protrusion amount.

  Therefore, according to the above-described embodiment, when the lid body 3 rotates with respect to the frame 2, the first regulating means 26 allows the lid body 3 to move downward, and the rear side of the lid body 3. Thus, the second restricting means 27 allows the lid body 3 to move in the forward direction and suppresses the lid body 3 from projecting upward. Therefore, comparing FIGS. 6 and 7, compared with the case where the pin 53 as shown in FIG. The rotation width b can also be suppressed. Therefore, the dead space formed in consideration of the rotation widths a and b can be reduced. Further, even when used in a limited space such as an automobile, the volume of the frame 2 can be formed large, and the storage space can be expanded.

  Furthermore, since the downward movement of the lid body 3 is urged by the movement of the lid body 3 in the front-rear direction via the second restricting means 27 during the opening operation, the position of the lid body 3 in the open position can be compared. The lid 3 can be guided downward in the open position, and the amount of protrusion of the end of the lid 3 from the opening surface of the frame 2 can be suppressed. Therefore, an object can be easily put in and out without hooking an object on the protruding end of the lid 3.

Further, the first guide 25 regulates the upward movement of the lid 3 by the second guide 21 and the second pin 16 while regulating the movement of the lid 3 in the front-rear direction via the first pin 17. Thus, the downward movement of the lid 3 can be allowed. Accordingly, it is possible to simplify the mechanism and reduce the cost while suppressing the amount of protrusion above and behind the end of the lid 3 during the opening / closing operation without requiring a complicated mechanism.
Further, since the lid 3 can be changed from the closed position in the horizontal posture to the open position in the vertical posture through the two means of the first restricting means 26 and the second restricting means 27, the capacity is secured by using the square frame 2. However, there is an advantage that the smooth and compact lid 3 can be opened and closed.

  Moreover, when the lid 3 is moved from the closed position to the open position or from the open position to the closed position, an elastic force is applied by the torsion spring 29, and the elastic return force generated by passing the reversal point causes a complicated mechanism or electric Since the movement of the lid 3 to the open position and the closed position can be performed semi-automatically without using a special means, the operability of the opening / closing operation by the occupant can be improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, an example in which the opening / closing mechanism 4 is applied to the in-vehicle center console 1 has been described. However, the present invention is not limited thereto, and an opening / closing member such as a lid is opened / closed with respect to the frame. If it is a mechanism, it is applicable not only to vehicle-mounted but to various apparatuses.

  Moreover, although the case where the cover body 3 and the frame 2 are connected by the torsion spring 29 has been described, the present invention is not limited to the torsion spring 29 and has one end side and the other end side and passes through the reversal point. As long as the elastic member generates an urging force, various elastic members such as a coil spring can be used. Further, the first restricting means 26 or the second restricting means 27 may be constituted by electric means such as a motor and a gear.

Further, in the present embodiment, the first restricting means 26 and the second restricting means 27 may be configured on the side wall 11 of the center console 1, respectively. By providing the two regulating means 27, the number of parts can be reduced and the cost can be reduced.
Alternatively, the second pin 16 may be provided on the lid 3, the second guide 21 may be provided on the frame, and the second pin 17 may be slidable with respect to the second guide 21. Further, the first guide 25 may be formed in an arc shape or the like. Furthermore, it is good also as a structure which provides a handle and a recessed part in the front part of the cover body 3, and raises this hook member and performs opening operation | movement.
