Description

Small Object Storage Device {SMALL ARTICLE HOUSING DEVICE}

The present invention relates to a small-sized object storage device, and more particularly, to a small-sized object storage device that is very suitable for embedding and use in the center console box of a vehicle.

BACKGROUND ART A box body provided with an openable cover body in an opening on an upper surface thereof is generally embedded in a center console box or the like for use as a glove compartment or a cup holder.

An example of this kind of small article storage device is shown in FIG. The storage device 1 is composed of a box 2 having an open top and a cover 3 for covering an opening of the top of the box 2, the fixed shaft 4 being formed on the side wall of the box 2. And the main guide groove 5 forming an arc shape centering on the fixed shaft 4 and the middle portion of the main guide groove 5 in the centrifugal direction, and also centering the upper end of the main guide groove 5. The sub guide groove 6 which forms an arc shape is formed.

On both side portions of the lid 3, the sub guide groove at the time of closing the first movable shaft 7 and the lid 3 positioned at the upper end of the main guide groove 5 when the lid 3 is closed. The 2nd movable shaft 8 located in the upper end part of (6) is formed. These pair of movable shafts 7 and 8 are able to move in the guide groove according to the opening and closing operation of the lid 3. In addition, the first movable shaft 7 is connected to the fixed shaft 4 via the arm 9.

In the storage device 1 comprised in this way, when the cover body 3 is opened in a closed position, the cover body 3 will be centered around the 1st movable shaft 7 located in the upper end part of the main guide groove 5 first. ) Will be rotated. This rotation continues until the 2nd movable shaft 8 moves in the sub guide groove 6 and reaches the main guide groove 5 (rotation range A shown in FIG. 2).

When the lid 3 is further opened in this state, both the first and second movable shafts 7 and 8 move along the main guide groove 5, and the first movable shaft 7 is arm 9. Since the lid 3 is connected to the fixed shaft 4, the lid 3 is rotated around the fixed shaft 4. And the 2nd movable shaft 8 rotates to the position which abuts the lower end part of the main guide groove 5 (rotation range B shown in FIG. 2).

When the lid 3 is closed, the lid 3 is operated in the reverse order of the above procedure. In other words, the first movable shaft 7 connected to the fixed shaft 4 by the arm 9 moves along the main guide groove 5 to the upper end thereof. On the other hand, since the second movable shaft 8 is mated with the branched end of the sub guide groove 6 at the position where the first movable shaft 7 abuts on the upper end of the main guide groove 5, the main guide groove 5 The lid 3 is rotated to the closed position by moving the second movable shaft 8 into the sub guide groove 6 about the first movable shaft 7 which is stopped at the upper end of the sub guide groove 6.

In the storage device 1 described above, since the lid 3 is substantially supported by the first and second movable shafts 7, 8, at the start of the opening operation of the lid 3, The friction torque generated between the inner peripheral surface of the upper end of the main guide groove 5 acts on the first movable shaft 7, and the slide contact resistance generated between the sub guide groove 6 is applied to the second movable shaft. It acts on (8). Therefore, these fixed shafts 4, main guide grooves 5, sub guide grooves 6, and first movable shafts 7 are provided in order to prevent the sliding contact sound or the swinging (a rattling phenomenon) during the opening and closing operation. ) And very high precision have been required for the mutual positional relationship of the 2nd movable shaft 8. In addition, this caused a high production cost.

The present invention has been made to solve the above problems of the prior art, and its main object is to ensure the rigidity in the closed state of the lid and the smoothness in the opening and closing operation, and to reduce the manufacturing cost thereof. An improved compact object storage device is provided.

In the present invention for achieving the above object, the main guide groove (5) forming an arc shape centering on the fixed shaft (4) on the side wall and an arc shape centering on one end of the main guide groove (5) In addition, the box body (2) having a sub-guide groove (6) branched in the centrifugal direction from the main guide groove; A first movable shaft 7 engaged with the main guide groove 5 and a second movable shaft 8 engaged with the sub guide groove 6 at the time of closing are provided, and the opening of the box 2 is opened. A lid 3 for covering; An arm 9 which connects the fixed shaft 4 and the first movable shaft 7 to each other and has a small object accommodating at least a part of the lid 4 to be accommodated inside the box 2 when opened. In the device (1), the groove width of the portion accommodating the first movable shaft (7) at the time of closing the lid (3) in the main guide groove (5) is the width of the first movable shaft (7). It is formed to match the diameter so as to have a frictional force against the movement of the first movable shaft (7), the groove width of the other portion than the diameter of the first movable shaft (7) and the second movable shaft (8) 2α)).

In this way, the rigidity in the closed state of the lid and the smoothness in the opening and closing operation can be ensured only by increasing the accuracy of a part of the guide groove.

Embodiment of the Invention

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

As described in the above-described prior art column, the rotational trajectory of the first movable shaft 7 is defined by an arm 9 which rotatably fixes one end thereof to the fixed shaft 4. The closed end of the lid 3 is defined at a position where the first movable shaft 7 abuts on the upper end of the main guide groove 5. Moreover, in the rotation range A shown in FIG. 2, the 2nd movable shaft 8 moves in the sub guide groove 6 centering on the 1st movable shaft 7, and in the rotation range B, the main guide groove 5 is carried out. The trajectory is defined by).

Therefore, in order to obtain smooth operation without swing in the rotation range A in which the lid 3 rotates around the closed position of the lid 3 and the first movable shaft 7, the upper end of the main guide groove 5 It is preferable that the first movable shaft 7 is closely engaged with the inner circumferential surface, and the second movable shaft 8 is loosely engaged with the sub guide groove 6.

In addition, in order to obtain smooth operation in the rotation range B in which both the first and second movable shafts 7 and 8 move along the main guide groove 5, the first and second movable shafts are provided in the main guide groove 5. It is desirable that (7,8) be loosely engaged.

From the above point of view, the precision setting of the guide groove was made as follows.

In order to strictly regulate the three points of the upper side, the lower side, and the front side of the outer periphery of the first movable shaft 7 at the upper end of the main guide groove 5, the first movable shaft 7 is relatively closely engaged with the first movable shaft 7. The dimensional tolerance is set in the ridge region in Fig. 1 so that the ridge region in Fig. 1 corresponds to a portion accommodating the first movable shaft 7 when the lid 3 is closed. In this region, the groove width of the main guide groove 5 is set to have a dimensional tolerance so as to match the diameter of the first movable shaft 7 so as to have a frictional force against the movement of the first movable shaft 7. In the opening operation, the second movable shaft 8 slides in contact with the outer circumferential surface of the sub guide groove 6 by the operating force applied to the lid 3, but in the closing operation, the sub guide groove 6 Since the second movable shaft 8 can be brought into a non-contact state, the second movable shaft 8 can be Only the smoothness of the outer inner circumferential surface of the sub guide groove 6 is considered, and the precision of the groove width and the shaft diameter is loosely set. That is, the clearance dimension α on the one side between the second movable shaft 8 and the sub guide groove 6. Is dimensioned to have

In addition, since the trajectory of the first movable shaft 7 is defined solely by the arm 9 in the recessed region in the main guide groove 5, the first movable shaft 7 and the main guide in this recessed region. The spacing accuracy of the grooves 5 can be completely ignored.

The fluctuation of the lid body 3 in the region of the main guide groove 5 depends on the engagement distance between the second movable shaft 8 and the main guide groove 5. By the opening and closing operation force applied, the second movable shaft 8 slides into contact with the inner inner circumferential surface of the main guide groove 5 during the opening operation, and the second movable shaft 8 is the main guide groove ( Slide contact with the outer inner peripheral surface of 5). Therefore, as long as the inner circumferential surface of the main guide groove 5 is smooth, no special precision is required for the groove width, so the accuracy of the groove width and the shaft diameter is loosely set. In addition, since the stopper of an open limit may be made into another member, the precision of the lower end part of the main guide groove 5 may be low. ) And the main guide groove (5) is dimensioned to have a margin (α) on one side and a margin (2α) corresponding to twice on both sides. In addition, when the spring means is provided on the outer inner circumferential surface (or the inner outer circumferential surface) of the main guide groove 5 so that the second movable shaft 8 is always in sliding contact, the outer inner circumferential surface (or the inner inner circumferential surface) in the recess region is provided. You just need to smooth the bay.

As described above, according to the present invention, since the first movable shaft does not come into contact with the guide groove except when closed, and the second movable shaft can make sliding contact with only one inner circumferential surface of the guide groove, the slide contact resistance during the opening and closing operation is greatly reduced. Can be reduced. In addition, since the trajectories of the first and second movable shafts do not need to coincide with each other, although the two axes pass through the common guide groove, the accuracy of the mutual positional relationship between the two axes and the grooves does not have to be made very high. .

Therefore, according to the present invention, a great effect is obtained to secure the rigidity in the closed state of the lid and the smoothness in the opening and closing operation, and to reduce the manufacturing cost thereof.
