Description

  The present invention relates to a vehicle console box such as an overhead console box that is attached to an appropriate location such as a ceiling of a passenger compartment and has an accommodating portion for storing small items such as glasses.

As shown in FIG. 8, a conventional console box for a vehicle of this type has a console body b having a storage room a having an open bottom surface attached to an appropriate position on a ceiling c of the vehicle. The lamp d or its operation switch e is installed, and the console body b is provided with a lid-like holder body g having an accessory case f such as glasses for closing the opening of the storage chamber a. It is configured to be capable of opening and closing (see Patent Document 1 and Patent Document 2).
Japanese Patent Laid-Open No. 11-16591 (paragraphs 0009 to 0025, FIGS. 1 to 3) JP 2001-151023 (paragraphs 0009 to 0025, FIGS. 1 to 3).

  The holder body g is configured to be opened in the vertical direction by its own gravity and to be fully opened by removing the lock mechanism h from the console body b, but is accommodated in the holder body g. In order to make it easier to take out the small items, it is preferable that the small items are further opened from the vertical direction so that the small accessory portion f faces downward to some extent.

  Therefore, as shown in FIG. 9, the holder body g is detachably mounted on the console main body b via the support shaft j, and is energized by an opening means (not shown) using a spring or the like, so that the storage chamber a is opened. The opening is biased in the opening direction, and the state in which the opening of the storage chamber a is closed is held by the lock mechanism h.

  Accordingly, when the lock mechanism h is removed, the holder body g is opened in the vertical direction by the moment due to its own gravity and the moment due to the urging force of the opening means (not shown) until it becomes the vertical direction. Only the moment due to the urging force opens to the state of the two-dot chain line in FIG. 9, and in this state, it is easy to take out small items such as glasses housed in the small item compartment f provided in the holder body 1. Yes.

  However, in the conventional vehicle console box configured as described above, by removing the lock mechanism h, as shown in FIG. 10, the opening moment of the holder body g is the biasing force of the opening means in the initial stage of opening. Moment A (indicated by the alternate long and short dash line) due to gravity and moment B (indicated by broken line) due to the gravity of the holder body g itself are added, resulting in a sudden opening as indicated by the solid line C, which is a combination of both moments (dotted circle) Inner), there is a risk that not only will the quality be lowered, but also the small items in the small item portion f may jump out.

  For this reason, a drive gear m that meshes with the driven gear k is provided for the support shaft j, and the one that attempts to restrict and control the urging force of the opening means by incorporating the hydraulic equal hydraulic damper mechanism n through the driven gear k is used. However, in the hydraulic damper mechanism n, for example, when the holder body g tries to rotate quickly, it becomes difficult for the liquid body or the like to pass through the orifice, and the damper effect is enhanced. It has been very difficult to select a damper mechanism that obtains the opening motion of the holder body with a sense of quality, such as whether to use it or what to do with the orifice shape.

  In view of this, the present invention controls the opening speed by generating a biasing force of the opening means or a moment in the closing direction against the gravity of the holder body at the initial stage of opening of the holder body with a simple configuration. An object of the present invention is to provide a vehicle console box configured to prevent a sudden opening operation.

  In order to achieve the above-described object, the present invention enables a holder body having a small object storage portion to be opened via a support shaft in a console body having a storage chamber having an open lower surface, in a lid shape that closes the storage chamber. A lock mechanism that pivots and holds the closed state of the holder body is provided in the console body, and a counterweight mechanism that biases the holder body in the closing direction is provided, and the lock state by the lock mechanism is released. When the holder body is opened, the opening speed due to the opening moment of the holder body is controlled.

  With this configuration, in the present invention, when the holder body is opened, a moment in the closing direction acts on the counterweight mechanism with respect to the opening moment of the holder body, and the opening operation speed of the holder body is controlled. Therefore, the moment in the closing direction of the holder body can be easily controlled by design simply by selecting the weight of the counterweight, etc., and as a result, the holder body can obtain a smooth rotation characteristic that is almost flat throughout the entire opening range. Can do.

  In order to achieve the above object, the present invention provides a console main body having a storage chamber with an open bottom surface in a state of urging a holder body having a small article storage portion in a lid shape that closes the storage chamber in the opening direction. When the console body is provided with an opening means that is pivotally mounted so that the holder body can be closed, a counterweight mechanism that urges the holder body in the closing direction is provided and locked. When the holder body that has been unlocked by the mechanism is opened by the opening means, the opening speed of the holder body due to the moment by the opening means and the moment by the gravity at the time of opening of the holder body is controlled. To do.

  With this configuration, when the holder body is opened, the moment in the closing direction acts on the counterweight mechanism with respect to the moment due to the gravity of the opening means and the holder body itself, and the opening operation speed of the holder body by the opening means is increased. Since it is controlled, the moment in the closing direction can be easily controlled in design by simply selecting the weight of the counterweight, etc., in relation to the gravity of the opening means or the holder body itself. As a result, the holder Smooth rotation characteristics that are nearly flat over the entire opening of the body can be obtained.

  Further, the counterweight mechanism according to the present invention is configured by installing the counterweight on the other end side of the mounting arm provided on the support shaft at one end side, and therefore the structure of the counterweight itself is simple. There is no significant change in the structure of the ceiling side.

  In addition, since the counterweight mechanism according to the present invention is configured by installing the counterweight on the holder body itself, the structure of the counterweight itself is still simple, so the structure on the vehicle interior ceiling side and the like is greatly changed. There is nothing to do.

  As described above, according to the present invention, when the holder body is opened, the counterweight mechanism has a moment in the closing direction against the moment caused by the gravity of the opening means and the holder body itself. Since the operation speed is controlled, the moment in the closing direction can be easily controlled by design by simply selecting the weight of the counterweight, etc., in relation to the gravity of the opening means or the holder body itself. In addition, it is possible to obtain smooth rotation characteristics that are almost flat in the entire opening range of the holder body.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

(Embodiment 1)
FIG. 1 is a perspective view of an overhead console box, which is a vehicle console box adopting the first embodiment of the present invention, drawn from obliquely below, and FIG. 2 is a perspective view showing a state in which the holder body of FIG. 1 is opened. FIG. 3 is a perspective view in which a part of the holder body opened is broken and drawn, and FIG. 4 is a schematic side view of the holder body.

  In the figure, a console body 1 has a storage chamber 2 having an open lower surface and is attached to a vehicle compartment ceiling 3, and a holder body 4 is mounted so as to be openable and closable with a configuration described later so as to close the storage chamber 2. Yes.

  The holder body 4 has an accessory storage portion 5 for storing accessories such as glasses on one end side, and a supporting shaft 6 is provided on each side wall portion on the other end side. The holder body 4 is constantly urged in the opening direction X by, for example, a spring as the opening means shown in the figure.

  A counterweight mechanism is configured by attaching mounting shafts 9 a extending to both ends of the counterweight 9 to both the other end sides of the mounting arm 8.

  On the open end side of the holder body 4, an engaging piece portion 13 that constitutes a locking mechanism of the holder body 4 together with an engaging portion (not shown) of the console body 1 is provided, and the engaging piece portion 13 is engaged. By engaging with the part, the closed state of the holder body 4 with respect to the console body 1 is held against the biasing force X of the opening means (spring), and the engaging part on the console body 1 side is, for example, By adopting a heart cam and pushing the holder body 4 into the console main body 1 side, the engaging piece 13 is separated from the engaging portion.

When the opening stroke of 4 is taken, the urging force X in the opening direction of the opening means changes as indicated by a solid line A, and the gravitational moment Z of the holder body 4 changes abruptly in the initial stage and changes as indicated by a broken line B. However, the counterweight 9 also works, and the force Y in the closing direction of the holder body 4 changes as indicated by a two-dot chain line D against the urging force and gravity of the holder body 4.

  As a result, the force exerted on the holder body 4 is such that the biasing force X in the opening direction of the opening means and the moment Z due to the gravity of the holder body 4 and the moment Y in the closing direction of the holder body 4 due to the opening means cancel each other. Thus, the resultant force appears as a one-dot chain line C, and this resultant force changes flatly, and the opening operation speed of the holder body 4 changes substantially flat.

  Then, by simply selecting the weight of the counterweight 9 and the like, the moment Y in the closing direction can be easily controlled by design in relation to the biasing force of the opening means or the gravity of the holder body 4 itself.

  Further, since the counter weight mechanism is configured by installing the counter weight 9 on the other end side of the mounting arm 8 provided on the support shaft 6, the counter weight 9 itself has a simple structure, such as the vehicle interior ceiling side 3 and the like. It can be adopted without greatly changing the structure.

  In the above embodiment, in addition to the moment Y in the closing direction by the counterweight 9, the damper mechanism 12 can be used in combination.

  In this case, the support shaft 6 is mounted so that one end sides of the drive gear 7 and the mounting arm 8 can rotate together. The drive gear 7 meshes with the driven gear 10, and the driven gear 10 is a holder. It is pivotally attached to a shaft body 11 provided on both side walls of the body 4, and a hydraulic system or a spring is used between the side walls of the holder body 4 and the driven gear 10 in the shaft body 11. A damper 12 is disposed, and is configured to restrict and control the biasing force in the opening direction of the holder body 4 biased to the support shaft 6 via the driven gear 10 and the drive gear 7.
