Storage structure for vehicle cabin interior
A storage structure is configured that can be assembled more easily. The storage structure is provided with a lid capable of being opened and closed. The lid is configured to swing about a swing axis from an opened state to a closed state. The lid has a center of gravity located on a far portion of the lid relative to the swing axis such that swinging movement of the lid to the opened state occurs due to a weight distribution of the lid itself relative to the swing axis. Thus, the lid swings from the closed state to the opened state with the center of gravity of the lid having being vertically disposed below the swing axis when the lid is in the closed state.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to a storage case. More specifically, the present invention relates to a storage structure configured to be arranged in an interior of a vehicle cabin, with the storage structure having a lid that can be opened and closed.
2. Background Information
Storage cases used to store small objects or to serve as cup holders are often provided inside the cabins (passenger compartments) of vehicles. Some such storage cases are provided with a lid (cover) that can be opened and closed. Among the lidded storage cases, some are configured with a lid that move independently to a fully opened state after only being slightly opened, while others are configured such that after pushing down on the lid, the lid then automatically moves to the opened state (see Japanese Laid-Open Patent Publication No. 2004-224114).
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved storage structure. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
SUMMARY OF THE INVENTIONThese kinds of storage case lids that were just described use a spring to apply a force against the lid in an opening direction during opening and closing of the lid. Theses springs are typically configured to load the lid across the entire range of motion from the closed state to the opened state. Thus, the spring of these lids has a strong spring force, which tends to make it difficult to assemble theses types of lids to the storage cases.
One object of the present invention is to provide a storage structure that can be assembled more easily.
In accordance with one aspect of the present invention, a storage structure is provided that basically comprises a lid support, and a lid. The lid is coupled to the lid support to selectively move between a fully opened state and a fully closed state about a swing axis. The lid includes a first portion disposed on a first side of the swing axis when the lid is in the fully closed state relative to the lid support and a second portion disposed on a second side of the swing axis when in the lid is in the fully closed state relative to the lid support. The lid has a center of gravity located on the first portion of the lid such that swinging movement of the lid to the fully opened state occurs due to a weight distribution of the lid itself relative to the swing axis.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to
The lid 1 has a pair of arms 2L and 2R located at opposite ends. The lid 1 wit with the arms 2L and is preferably a one-piece unitary member constructed from a rigid material with a limited degree of flexibility such as a rigid plastic material. The lid 1 is pivotally or swingable mounted to a lid support or casing unit 3 that is secured to the interior of the vehicle cabin in a conventional manner. Thus, the lid is coupled to the lid support or casing unit 3 to selectively move between an opened state and a closed state about a swing axis O (
Although only one arm 2R is shown in
The arm 2R is provided with a locking claw 2a and a blocking piece 2b. The other arm 2L is provided with neither the locking claw 2a nor the blocking piece 2b. Furthermore, the other arm 2L is not provided with an arm portion corresponding to the arm portion of the arm 2R that extends to the lock claw 2a. As shown in
As shown in
Additionally, the first lid portion T in which the thickness of the lid 1 is larger and the internal ribs 1 a are provided corresponds to the region between the portions where the two arms 2L and 2R connected. Since this embodiment is configured such that the lid 1 is supported at both ends by the two arms 2L and 2R, reinforcing the first lid portion T also helps improve the strength and rigidity of the lid 1.
Meanwhile, as shown in
As shown in
The casing unit 3 includes a plurality (four).of fastening parts 3c for fastening the casing unit 3 to the vehicle interior. The fastening parts 3c are formed on the outside surface of the casing unit 3. As shown in
The lid 1 is spring loaded in an opening direction by the spring 5, which serves as a force applying device. As shown in
The spring 5 is installed such that it spring loads the lid 1 in an opening direction (counterclockwise in
As shown in
As shown in
However, the appearance of the interior of the casing unit 3 would seem odd if the receiving opening 3f were the only hole visible when the lid 1 was opened and, furthermore, the appearance would be degraded if the back side of the casing unit 3 were visible through the arm receiving opening 3f. Furthermore, small articles might fall through the opening 3f into the back side of the casing unit 3 and dust and dirt might enter into the region on the back side of the casing unit 3. In this embodiment, the arm 2R has a blocking piece 2b, as shown in
The operation of opening the lid 1 of the vehicle cabin interior storage case will now be explained. When the case is in the closed state shown in
Although the spring force of the spring 5 stops acting against the lid 1 in the opening direction at the position P2 (position corresponding to the limit of the spring force in the opening direction), the weight of the lid 1 itself causes the lid 1 to continue the swing movement in opposition to a spring force of the spring 5 acting in the closing direction until the lid 1 reaches the fully open position P4 shown in
When the lid 1 reaches the position P3 indicated with a solid-line sketch in
In the fully opened state P4 shown in
When the lid 1 is to be closed, the tip end of the lid 1 is lowered in the closing direction until the tip end of the lid 1 presses against the rubber protrusion 3b. The locking claw 2a thus engages with the locking striker and the lid 1 is locked in the closed state. The rubber protrusion 3b remains in a somewhat squashed state, thus preventing looseness (e.g., rattling) of the lid 1 while it is in the closed state.
As described previously, the casing unit 3 has the receiving opening 3f that serves to prevent contact with the arm 2R when the arm 2R swings and the arm 2R had a blocking piece 2b that serves to block the opening 3f when the lid 1 is fully opened. Thus, the opening and closing movement of the lid 1 is not inhibited and the aesthetic appearance of the casing unit 3 is not degraded due to exposure of the receiving opening 3f when the lid 1 is fully opened.
With this embodiment, since the center of gravity G of the lid 1 is positioned on the far side of the swing axis O when the lid 1 is closed, a rotational moment acting in the opening direction can be exerted against the lid 1 due to the weight of the lid 1 itself. Consequently, the force applying device used to apply a swinging force against the lid 1 in the opening direction can be reduced in size or eliminated altogether. As a result, the vehicle cabin interior storage case that is easier to assemble can be obtained.
In this embodiment, the center of gravity G of the lid 1 is positioned higher than the swing axis O when the lid 1 is closed. Consequently, the range of motion through which the lid 1 (i.e., the center of gravity G thereof) moves due to its own weight from the fully closed position P1 to the fully open position P4 can be increased. As a result, the force applying device used to apply a swinging force against the lid 1 in the opening direction can be reduced in size or eliminated altogether.
In this embodiment, the ribs 1 a serving as a reinforcing structure are provided inside the lid 1 in the first lid portion T located on the far side of the swing axis O when the lid 1 is closed. Consequently, the rigidity and strength of the lid 1 can be increased and the rotational moment acting against the lid 1 in the opening direction due the weight of the lid 1 itself can be increased because the ribs 1a increase the mass of the lid 1. The increased rotational moment makes it even more feasible to reduce the size of the force applying device used to apply a swinging force against the lid 1 in the opening direction or eliminate the force applying device altogether. By using ribs 1a as the reinforcing structure, the mass (weight) and the position of the center of gravity G can be adjusted easily and accurately by varying the spacing (pitch), thickness, number, etc., of the ribs 1a.
In this embodiment, by providing the ribs 1a inside the first lid portion T of the lid 1, the position of the center of gravity G can be adjusted and the rigidity can be improved in an effective manner while suppressing the resulting increase in weight in comparison with a case in which ribs are provided throughout the entirety of the lid 1.
In this embodiment, the thickness of the lid 1 is thicker in a first lid portion T near the center of gravity G, which is located on the far side of the swing axis O when the lid is closed, than in other regions. As a result, the rotational moment acting in the opening direction due to the weight of the lid 1 itself can be increased, making it even more feasible to reduce the size of the force applying device used to apply a swinging force against the lid 1 in the opening direction or eliminate the force applying device altogether. Additionally, by making the thickness of the lid 1 thicker in the first lid portion T, it becomes easier to arrange the ribs 1a constituting the reinforcing structure inside the lid 1 and, thus, to contribute to increasing the rotational moment in the opening direction.
This embodiment is provided with the stopper 6 and the foamed body 7. The stopper 6 is made of an elastic material and serves to support the lid 1 when the lid 1 is in the fully opened position P4. The foamed body 7 serves as a buffer member and is arranged to contact the lid 1 at a position P3 that is reached before the fully opened position P4 is reached when the lid 1 is opened. The foamed body 7 is configured to damp the movement of the lid 1 as the lid swings toward the fully opened position P4. Thus, the impact made by the lid 1 against the stopper 6 when the lid 1 is opened can be softened and the generation of a noise due to the striking of the lid 1 against the stopper 6 can be suppressed. Additionally, the structure is much simpler than the structure of a damper mechanism that employs air pressure or hydraulic pressure. As a result, both the size and the manufacturing cost of the vehicle cabin interior storage case can be reduced.
In this embodiment, the spring 5 is provided as a force applying device that applies a force against the lid 1 in the opening direction. As a result, the lid 1 can be opened more reliably when the vehicle cabin interior storage case is tilted (e.g., due to the vehicle being on a slope) such that the rotational moment resulting from the weight of the lid 1 is smaller than when the storage case is not tilted.
In this embodiment, the spring force of the spring 5 acts on the lid 1 in an opening direction when the lid 1 is in any position ranging from the fully closed position P1 to a prescribed position P2 that is reached prior to the fully open position P4 when the lid 1 swings toward the fully open position P4. As a result, the spring 5 can be made smaller than in a case where it applies a spring force in the opening direction through the entire range of motion from the fully closed position P1 to the fully opened position P4. Additionally, by weakening the force acting on the lid 1 at the fully opened position P4, the sound of the lid 1 striking against the stopper 6 can be suppressed.
In this embodiment, the casing unit 3 has the receiving opening 3f for preventing contact with the arm 2R when the arm 2R swings and the arm 2R has a blocking piece 2b configured and arranged to block the receiving opening 3f when the lid 1 is fully opened. As a result, the opening movement of the lid 1 is not inhibited and the receiving opening 3f is prevented from being exposed in the casing unit 3 when the lid 1 is fully opened, thus preserving the aesthetic appearance of the casing unit 3.
Second EmbodimentReferring now to
The vehicle cabin interior storage case in accordance with this embodiment has the vertically oriented tongue piece 3e provided above the locking striker 3d of the casing unit 3A, as shown in
Also, during the open movement, the flexing of the tongue piece 3e serves to soften the impact of the contact between the protrusion 2c and the tongue 3e. As a result, sound of the lid 1 (arm 2R) striking against the case 3A when the lid 1 reaches the fully opened position can be reduced and the lid 1 can be stopped in a more controlled manner when it reaches the fully opened position. Additionally, since the lid 1 is locked as just described when it is in the fully opened state, the lid 1 can be prevented from rattling or otherwise emitting abnormal noise due to vibrations of the vehicle.
In this embodiment, the lid 1 has two arms 2L and 2R that are swingably supported on both sides of the casing unit 3A. The casing unit 3A has a pair of recessed areas for receiving the two arms 2L and 2R, respectively. At least one of the two arms 2L and 2R (2R in this embodiment) has the protrusion 2c configured and arranged to touch against the casing unit 3 when the lid 1 is fully opened, and the casing unit 3A has an elastically flexible tongue piece 3e provided at the portion thereof where the protrusion 2c touches when the lid 1 is fully opened. As a result, the sound of the lid 1 striking against the casing unit 3A when the lid 1 is opened to the fully opened position can be softened and the lid 1 can be made to stop in a more controlled manner when it is moved to the fully opened position.
