The vehicle center lower box device may be disposed at the center and the lower portion in the vehicle width direction, may be a vehicle accessory device disposed on the ceiling of the passenger compartment, or may be other devices. .
Hereinafter, in the embodiment of the present invention and the illustrated example, the case where the housing structure device 10 is a so-called bin-type vehicle glove box device will be described as an example.

As shown in FIG. 1, the housing structure device 10 includes a fixed member 20, a movable member 30, and an urging / biasing release device 40.

The fixing member 20 is a member that is fixed to an instrument panel that is an interior member of the vehicle. As shown in FIG. 2, the fixing member 20 includes a recess forming wall 21 including a recess 21 a that opens to the passenger compartment side (rear side of the vehicle). The recess forming wall 21 may be formed integrally with the instrument panel, or may be formed separately from the instrument panel and fixedly attached to the instrument panel.

The movable member 30 includes a storage portion S that is open upward and can store a stored item. The movable member 30 is movable with respect to the fixed member 20 between a closed position 30a (see FIG. 2) and an open position 30b (see FIG. 3). A force due to its own weight is always applied to the movable member 30 from the closed position 30a to the open position 30b. The opening / closing speed of the movable member 30 with respect to the fixed member 20 may be moderated using a damper (not shown). The movement of the movable member 30 relative to the fixed member 20 may be a linear motion, a swing, or a rotation. In the illustrated example, the movable member 30 is illustrated as being rotatable about the axis P with respect to the fixed member 20.

When the movable member 30 is in the closed position 30 a shown in FIG. 2, a part of the movable member 30 is in contact with the fixed member 20, and further movement to the closed side with respect to the fixed member 20 is restricted. . When the movable member 30 is in the closed position 30 a, the contact sound between the movable member 30 and the fixed member 20 is suppressed by a cushion rubber 51 provided on at least one of the fixed member 20 and the movable member 30. When the movable member 30 is in the closed position 30a, the opening of the storage portion S is located in the recess 21a, and the user cannot put in or out the storage item in the storage portion S.
When the movable member 30 is in the open position 30 b shown in FIG. 3, a stopper 31 formed of a part of the movable member 30 is in contact with a stopper contact portion (not shown) of the fixed member 20, and further to the fixed member 20. Movement to the open side is restricted. When the movable member 30 is in the open position 30a, the contact sound between the movable member 30 and the fixed member 20 is suppressed by a rubber member (not shown) provided on at least one of the fixed member 20 and the movable member 30. Also good. When the movable member 30 is in the open position 30b, the opening of the housing portion S is located in the vehicle interior through the recess 21a, and the user can put in and out the stored material in the housing portion S.

  The urging / biasing release device 40 may be provided corresponding to only one side of the movable member 30 in the left-right direction of the vehicle, or a pair of urging / biasing release devices 40 corresponding to both sides of the movable member 30 in the left-right direction of the vehicle. Also good.

The urging / biasing release device 40 includes a spring member 41. When the movable member 30 is at a predetermined position 30c between the closed position 30a and the open position 30b with respect to the fixed member 20, and when the movable member 30 is closer to the closed position 30a than the predetermined position 30c. The spring member 41 urges the movable member 30 toward the closed position 30a with respect to the fixed member 20. When the movable member 30 is located on the open position 30b side of the predetermined position 30c with respect to the fixed member 20, the biasing / biasing release device 40 applies the spring force of the spring member 41 to the fixed member 20. The spring member 41 releases the urging of the movable member 30 toward the closed position 30a with respect to the fixed member 20 while maintaining the same level as the spring force at the predetermined position 30c.

  In addition to the spring member 41, the urging / biasing release device 40 further includes an engagement protrusion 42 that is fixed to one of the fixed member 20 and the movable member 30, as shown in FIG. And a guide rail 43 fixed to the other of the movable members 30, and a lock piece 44 that moves along the guide rail 43.

  The spring member 41 is a coil spring. However, the spring member 41 is not limited to a coil spring, and may be made of a Conston spring or other springs. The spring member 41 is connected at one end to a spring fixing portion 41 a provided on a member (the other of the fixed member 20 and the movable member 30) provided with the guide rail 43 among the fixed member 20 and the movable member 30 and the other end. Is connected to a lock piece side spring fixing portion 41b provided on the lock piece 44, and biases the lock piece 44 against the member on which the guide rail 43 is provided (the other of the fixed member 20 and the movable member 30). .

The spring member 41 is provided with a spring fixing portion 41a when an intermediate portion of the spring member 41 may interfere with the guide rail 43 and / or the lock piece 44 and disturb the movement of the lock piece 44 along the guide rail 43. It is desirable to provide a spring member accommodating portion 41 c that accommodates the spring member 41 and restricts the posture of the spring member 41 in the member to be provided. This is because by restricting the posture of the spring member 41 by the spring member accommodating portion 41 c, it is possible to suppress the middle portion of the spring member 41 from interfering with the movement of the lock piece 44 along the guide rail 43.

  As shown in FIG. 1, the engagement protrusion 42 is a columnar or cylindrical protrusion. The engaging protrusion 42 may be formed separately from the member (one of the fixed member 20 and the movable member 30) provided with the engaging protrusion 42 and fixedly attached to the member. Therefore, it is desirable to be formed integrally with the member.

  As shown in FIG. 2, the guide rail 43 is connected to the first rail portion 43a extending in the moving direction of the movable member 30 relative to the fixed member 20, and one end portion in the extending direction of the first rail portion 43a. And a second rail portion 43b extending in a direction different from the extending direction of 43a. When the movable member 30 is rotatable about the axis P with respect to the fixed member 20 as in the illustrated example, the first rail portion 43a extends in an arc shape centering on the axis P, The second rail portion 43b extends in the radial direction about the axis P.

The second rail portion 43b extends linearly from the first rail portion 43a. However, as shown in FIG. 8, the second rail portion 43b is separated from the first rail portion 43a in order to increase the amount of movement of the second guide projection 44c described later in the second rail portion 43b. In addition to the linear portion that extends in a straight line, an extension portion 43d that is bent toward the spring member 41 side and slightly extended may be provided.

As shown in FIG. 1, the lock piece 44 is a resin molded product and has a single component configuration. The lock piece 44 includes an engagement receiving portion 44 a to which the engagement protrusion 42 can be engaged and disengaged, and first and second guide protrusions 44 b and 44 c that enter the guide rail 43 and move along the guide rail 43. Prepare.

  The engagement receiving portion 44a is provided on the opposite side of the lock one-side spring fixing portion 41b with respect to the first and second guide protrusions 44b and 44c. The engagement receiving portion 44a includes first and second opposing wall portions 44e and 44f that face each other. The engagement protrusion 42 can enter and exit between the first and second opposing wall portions 44e and 44f, and the engagement protrusion 42 enters between the first and second opposing wall portions 44e and 44f. Thus, the engagement protrusion 42 and the engagement receiving portion 44a are engaged with each other, and the engagement protrusion 42 is detached (disengaged) from between the first and second opposing wall portions 44e and 44f, whereby the engagement protrusion 42 is obtained. And the engagement receiving portion 44a are disengaged.

  Both the first and second guide protrusions 44 b and 44 c have the same size, and have a columnar shape or a cylindrical shape so that they can move smoothly along the guide rail 43. The diameter of the first and second guide protrusions 44b and 44c in a cross-sectional view is slightly smaller than the width of the first and second rail portions 43a and 43b of the guide rail 43.

Here, an operation common to the first and second embodiments of the present invention will be described.
(A) When the movable member 30 is in the closed position 30a, the first and second guide protrusions 44b and 44c of the lock piece 44 are both positioned on the first rail portion 43a of the guide rail 43 as shown in FIG. The lock piece 44 is movable in the moving direction of the movable member 30 relative to the fixed member 20 along the first rail portion 43a. The engaging protrusion 42 and the engaging receiving portion 44 a are engaged with each other (the engaging protrusion 42 enters the engaging receiving portion 44 a), and the force of the spring member 41 is applied to the movable member 30 via the lock piece 44. Can be communicated to. By urging the lock piece 44 with the spring member 41, the movable member 30 is urged toward the closed position 30a with a force larger than the force toward the open position 30b due to the weight of the movable member 30. Due to the urging force of the spring member 41, the movable member 30 is held at the closed position 30 a with respect to the fixed member 20.

(B) When the movable member 30 is moved to the open position 30b side, the movable member 30 is manually closed by placing a hand on the upper portion of the movable member 30 (a portion above the center in the vertical direction of the movable member 30 at the closed position 30a). When moved from the position 30a to the open position 30b side, the first and second guide protrusions 44b and 44c are both positioned on the first rail portion 43a, and the engagement protrusion 42 and the engagement receiving portion 44a are engaged. Since they are aligned, the lock piece 44 moves along the first rail portion 43a against the urging force of the spring member 41.
When the movable member 30 reaches the predetermined position 30c, as shown in FIG. 4, the second guide protrusion 44c reaches the end of the first rail portion 43a on the second rail portion 43b side.

(C) When the movable member 30 is moved from the predetermined position 30c to the open position 30b, as shown in FIG. 5, the second opposing wall portion 44f of the engagement receiving portion 44a is pushed by the engagement protrusion 42, Two guide protrusions 44c move from the first rail portion 43a to the second rail portion 43b. Since the second guide protrusion 44c moves from the first rail portion 43a to the second rail portion 43b, the movement of the lock piece 44 along the first rail portion 43a is restricted, and the spring force of the spring member 41 is movable. It is maintained at the same level (same or substantially the same) as the spring force when the member 30 is at the predetermined position 30c. Further, since the second guide protrusion 44c moves from the first rail portion 43a to the second rail portion 43b, the posture of the lock piece 44 with respect to the engagement protrusion 42 changes, and the engagement protrusion 42 and the engagement receiving portion 44a. Is disengaged (the engaging protrusion 42 comes out of the engagement receiving portion 44a).

(D) After the engagement between the engagement projection 42 and the engagement receiving portion 44a is released, the second guide projection 44c is moved to the second rail portion 43b when the movable member 30 is further moved to the open position 30b side. Since the engaging projection 42 and the engagement receiving portion 44a are disengaged, the biasing of the movable member 30 by the spring member 41 is released. Therefore, when the hand is released from the movable member 30, the movable member 30 moves to the open position 30b by the force of its own weight. It is also possible to manually move the movable member 30 to the open position 30b.

(E) When the movable member 30 is in the open position 30b, as shown in FIG. 3, the second guide protrusion 44c is moved to the second rail portion 43b, and the spring force of the spring member 41 is applied to the movable member 30. It is maintained at the same level as the spring force at the predetermined position 30c. Further, the engagement between the engagement protrusion 42 and the engagement receiving portion 44a is released. The movable member 30 is held at the open position 30b with respect to the fixed member 20 by the force of its own weight.

(F) When the movable member 30 is moved to the closed position 30a side, the movable member 30 reaches the predetermined position 30c when the movable member 30 is manually moved from the open position 30b to the closed position 30a against the force of its own weight. Immediately before, as shown in FIG. 6, the engaging protrusion 42 hits the first opposing wall portion 44e of the engaging receiving portion 44a.
When the movable member 30 is further moved toward the closed position 30a until reaching the predetermined position 30c, the first opposing wall portion 44e of the engagement receiving portion 44a is pushed by the engagement protrusion 42, and as shown in FIG. The second guide protrusion 44c moves from the second rail portion 43b to the first rail portion 43a. Since the second guide projection 44c moves from the second rail portion 43b to the first rail portion 43a, the posture of the lock piece 44 with respect to the engagement projection 42 changes, and the engagement projection 42 and the engagement receiving portion 44a change. Engage with each other (the engaging protrusion 42 enters the engaging receiving portion 44a).

(G) When the movable member 30 is moved from the predetermined position 30c to the closed position 30a, the first and second guide protrusions 44b and 44c are both positioned on the first rail portion 43a, and the engaging protrusion 42 and Since the engagement receiving portion 44a is engaged with each other, when the hand is released from the movable member 30, the movable member 30 moves with respect to the fixed member 20 until the closed position 30a is reached by the urging force of the spring member 41. It is also possible to manually move the movable member 30 to the closed position 30a.

Next, operations and effects common to the first and second embodiments of the present invention will be described.
Since the urging / biasing release device 40 urges the movable member 30 toward the closed position 30a when the movable member 30 is at the closed position 30a side with respect to the predetermined position 30c and the predetermined position 30c, (i) It is possible to prevent the movable member 30 at the closed position 30a from moving toward the open position 30b against the user's intention without operating the knob to release the lock. Therefore, it is possible to eliminate a mechanism for operating the knob to release the lock. Further, (ii) the movable member 30 at the closed position 30a can be moved to the open position 30b simply by manually moving the movable member 30 from the closed position 30a beyond the predetermined position 30c to the open position 30b. Therefore, the opening operability of the movable member 30 can be improved as compared with the conventional methods (a) and (b).
In addition, when the movable member 30 is located at the closed position 30a side of the predetermined position 30c and the predetermined position 30c, the biasing / biasing release device 40 biases the movable member 30 toward the closed position 30a, and the movable member 30 When 30 is on the open position 30b side with respect to the predetermined position 30c, the biasing of the movable member 30 is released while maintaining the spring force of the spring member 41. Therefore, the movable member 30 at the open position 30b is manually specified. The movable member 30 can be moved from the predetermined position 30c to the closed position 30a by the biasing / biasing release device 40 only by moving to the position 30c. Therefore, the closing operability of the movable member can be improved as compared with the conventional methods (a) and (b).
Furthermore, since the biasing / biasing release device 40 includes the spring member 41, a motor for moving the movable member 30 relative to the fixed member 20 is not necessary. Therefore, a motor and other wirings are unnecessary, which is advantageous in terms of cost compared to the conventional (c).

When the movable member 30 is located on the close position 30a side with respect to the predetermined position 30c and the predetermined position 30c, the first and second guide protrusions 44b and 44c are both positioned on the first rail portion 43a and the engagement protrusion 42 Since the engagement receiving portion 44a is engaged with each other, the movable member 30 can be biased toward the closed position 30a by the spring member 41 via the lock piece 44.

When the movable member 30 is closer to the open position 30b than the predetermined position 30c, the second guide protrusion 44c moves from the first rail portion 43a to the second rail portion 43b, whereby the first of the lock piece 44 Movement along the rail portion 43a can be restricted, and the spring force of the spring member 41 can be maintained at the same level as the spring force when the movable member 30 is at the predetermined position 30c.

When the movable member 30 is closer to the open position 30b than the predetermined position 30c, the second guide protrusion 44c moves from the first rail portion 43a to the second rail portion 43b, thereby providing the engagement receiving portion 44a. The lock piece 44 can be moved with respect to the engagement protrusion 42. Therefore, the engagement between the engagement protrusion 42 and the engagement receiving portion 44a can be released, and the biasing of the movable member 30 toward the closed position 30a by the spring member 41 can be released.

When the second rail portion 43b includes the extension portion 43d as shown in FIG. 8, the biasing force of the spring member 41 causes the second guide projection 44c to move more than the case where the extension portion 43d is not provided. The amount of movement of the second rail portion 43b can be increased, and the amount of movement of the lock piece 44 including the engagement receiving portion 44a with respect to the engaging protrusion 42 can be increased. Therefore, when the movable member 30 is moved from the open position 30b to the closed position 30a, the engagement protrusion 42 can be reliably applied to the first opposing wall portion 44e of the engagement receiving portion 44a. Can be reliably prevented from hitting the second opposing wall portion 44f of the engagement receiving portion 44a.

  Since the mechanism for releasing the lock by operating the knob can be eliminated, not only the arrangement of the knob is not restricted, but also the design of the housing structure device 10 can be improved by eliminating the knob.

Next, parts unique to each embodiment of the present invention will be described.
