Description

[Technical field]

[0001] The present invention relates to a storage box that can be used, for example, in a vehicle. [Background technology]

[0002] Vehicles such as motorcycles and four-wheeled vehicles are sometimes provided with storage boxes whose opening can be opened and closed with a lid (see, for example, Patent Document 1). In the storage box of Patent Document 1, a damper spring is suspended between the lid and the storage body. When the lid is opened, the damper spring pulls the lid, adjusting it so that the lid opens slowly. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. 8-8911 Summary of the Invention [Problem to be solved by the invention]

[0004] When the lid of the storage box in Patent Document 1 is closed, the damper spring resonates with vibrations caused when the vehicle is running, etc. The damper spring in Patent Document 1 has a resin coating layer on the hook portion, but this is not sufficient to prevent the coil portion from resonating.

[0005] The present invention has been proposed in view of the above-mentioned problems associated with the conventional technology, and has an object to provide a storage box capable of preventing resonance of an elastic body. [Means for solving the problem]

[0006] In order to overcome the above problems and achieve the intended object, the storage box of the present invention comprises: A lid for opening and closing the opening of the storage body; an elastic body that is provided between the lid body and the storage body and that can apply a biasing force in a direction in which the lid body is closed when the lid body is in an open position; The storage body has a cushioning body that is provided on the storage body and abuts against the elastic body when the lid is in a closed position. Effect of the Invention

[0007] According to the storage box of the present invention, the elastic body comes into contact with the buffer body when the lid is closed, so that the buffer body can prevent the elastic body from resonating. [Brief description of the drawings]

[0009] Next, a preferred embodiment of the storage box according to the present invention will be described below with reference to the accompanying drawings. In the following embodiments, the front, rear, left, right, top and bottom of the storage box are indicated based on the state of attachment to a vehicle such as a car. The rear direction is the direction in which the lid of the storage box opens. EXAMPLES

[0010] A scooter-type motorcycle is provided with a storage box 10 as shown in Fig. 1 inside a front leg shield FS rising from the front of the front rest floor on which the rider places his / her feet. The storage box 10 includes a box-shaped storage body 12 with an access opening 12a opening toward the rider (rearward), and a lid 16 that is supported by a pair of arms 14, 14 attached to the storage body 12 and opens and closes the access opening 12a of the storage body 12. The storage box 10 can hold the lid 16 in the closed position by abutting the lid 16 against the opening edge of the access opening 12a in the storage body 12 to close the access opening 12a, and then locking the lid 16 with a locking device (not shown) (see Fig. 1(a)). At this time, the lid 16 in the closed position of the storage box 10 is aligned with the front leg shield FS to form a part of the exterior of the storage box 10. In addition, the user can operate the storage box 10 to release the lock set by the locking device, thereby tilting the lid 16 toward the driver and opening the loading / unloading opening 12a of the storage body 12 (see FIG. 1(b)). In the storage box 10 of the embodiment, the storage body 12, the arm 14, and the lid 16 are made of molded synthetic resin.

[0011] As shown in FIG. 5, in the storage box 10, a pair of arms 14, 14 arranged opposite to each other with the storage body 12 sandwiched between them are supported by a support shaft 20 held by a bearing portion 18. The left and right arms 14, 14 rotate together with the support shaft 20 while being held by the bearing portion 18, so that the lid body 16 supported between both arms 14, 14 changes its posture so as to open and close the loading / unloading opening 12a. Specifically, one end of the right (one) arm 14 is connected to the right end (one end) of the support shaft 20, and one end of the left (other) arm 14 is connected to the left end (other end) of the support shaft 20. The other end of the pair of arms 14, 14 is connected to the lid body 16 provided so as to span between both arms 14, 14. The lid body 16 of the embodiment is formed integrally with a pair of arms 14, 14 and is composed of a lid body base that faces the loading / unloading opening 12a of the storage body 12 in the closed position, and a lid body cover that is attached to this lid body base and forms the driver's side of the lid body 16.

[0012] As shown in Figs. 2 to 4, the arm 14 includes a first arm portion 14a extending linearly from a lower end (one end) connected to the support shaft 20, and a second arm portion 14b extending backward from the first arm portion 14a in an arc shape centered on the support shaft 20 and connected to the lid body 16. An elastic body 22 is installed between the right arm 14 and the right side surface of the storage body 12 (see Figs. 2 to 5). The elastic body 22 in the embodiment is a tension coil spring (coil spring) having hook portions 22b on both ends of a coil portion 22a. The elastic body 22 is configured to apply a biasing force in a direction to close the lid body 16 when the lid body 16 is in an open position. The elastic body 22 has its lower hook portion 22b connected to the bent portion of the arm 14 where the arm 14 bends from the first arm portion 14a to the second arm portion 14b, and its upper hook portion 22b connected to the front right side of the storage body 12 forward of the lower end (opposite the loading / unloading opening 12a).

[0013] As shown in Figs. 2 to 4, the right arm 14 is braked by a rotary damper 24 to control the speed of posture change. In this embodiment, the rotary damper 24 provided on the right side surface of the storage body 12 meshes with a rack portion 14ba formed on the second arm portion 14b of the right arm 14. In this embodiment, the elastic body 22 and the rotary damper 24 are not provided corresponding to the left arm 14. Here, the left and right arms 14, 14 are set so as not to interfere with the storage body 12, and the arm 14 is not affected by anything other than the elastic body 22 and the rotary damper 24 when the lid body 16 changes posture.

[0014] As shown in FIG. 4, in an intermediate position between the closed position (see FIG. 2) and the open position (see FIG. 3) of the lid body 16, the elastic body 22 is configured to be in a first state in which the axial center of the support shaft 20 passes on an extension line of the axis L of the elastic body 22. In the first state of the elastic body 22, the connecting portion of the elastic body 22 to the storage main body 12, the coil portion 22a of the elastic body 22, the connecting portion of the elastic body 22 to the arm 14, and the axial center of the support shaft 20 are aligned in a straight line. In contrast, the elastic body 22 is configured to be in a second state in which it is stretched more than the first state between the intermediate position and the open position of the lid body 16, and between the intermediate position and the closed position. In this way, the elastic body 22 is configured to be most contracted in the first state and to stretch as the lid body 16 moves from the intermediate position to the closed position or the open position. Note that the elastic body 22 in the embodiment is set to a length with a certain amount of tension in the first state, but the elastic body 22 may be set to an initial length in which it is not stretched in the first state. When the lid body 16 is in the open position, an elastic force (biasing force) toward the closed position is applied to the arm 14 by the elastic body 22. When the lid body 16 is in the closed position, an elastic force (biasing force) toward the open position is applied to the arm 14 by the elastic body 22. The biasing force toward the closed position in the open position of the lid body 16 is set to be greater than the biasing force toward the open position in the closed position.

[0015] 2 to 6, the storage box 10 is provided with a first buffer body (buffer) 26 that is provided on the storage body 12 and comes into contact with the elastic body 22 when the lid 16 is in the closed position. The first buffer body 26 in the embodiment is provided on the right side surface of the storage body 12 in correspondence with the elastic body 22. More specifically, the first buffer body 26 is attached to a first base portion 28 that is integrally formed with the storage body 12 so as to protrude from the right side surface.

[0016] As shown in FIG. 2, the first buffer 26 of the embodiment is disposed so as to abut against the coil portion 22a of the elastic body 22 when the lid body 16 is in the closed position. More specifically, the first buffer 26 is formed narrower than the axial length of the coil portion 22a and disposed so as to abut against the axial center portion of the coil portion 22a. The first buffer 26 is disposed so as to partially overlap the elastic body 22 when the lid body 16 is in the closed position (see FIG. 6). The first buffer 26 of the embodiment is formed with a thickness of about 5 mm as a whole, and a portion of about 1 mm to 2 mm is set so as to interfere with the elastic body 22 when the lid body 16 is in the closed position.

[0017] As shown in FIG. 2, the first contact surface (contact surface) 26a of the first buffer 26 with the elastic body 22 is disposed on the opposite side of the movement direction of the elastic body 22 displaced with the opening of the lid body 16 with respect to the elastic body 22 in the closed position of the lid body 16. The first contact surface 26a extends rearward from top to bottom in accordance with the elastic body 22 inclined rearward from top to bottom in the closed position of the lid body 16. As shown in FIG. 6, the first contact surface 26a is configured to move in the opposite direction to the movement direction of the elastic body 22 displaced with the opening of the lid body 16 as it moves away from the storage body 12. The first contact surface 26a of the embodiment is inclined obliquely from between the elastic body 22 in the closed position of the lid body 16 and the right side surface of the storage body 12 toward the opposite direction to the movement direction of the elastic body 22 displaced with the opening of the lid body 16. The first contact surface 26a in the embodiment is set to contact between the coil portion 22a on the side of the storage body 12 and the side opposite to the moving direction of the elastic body 22 displaced with the opening of the lid body 16. In the embodiment, the first mounting surface 28a to which the first buffer body 26 is attached in the first base portion 28 is formed to be inclined from between the right side surface of the storage body 12 and the elastic body 22 in the closed position of the lid body 16 toward the opposite side of the moving direction of the elastic body 22 when the lid body 16 is displaced to the open position. The posture of the first contact surface 26a is determined by attaching the first buffer body 26 in the shape of a rectangular block to such a first mounting surface 28a. The first mounting surface 28a is formed wider than the first buffer body 26, so that the mounting position of the first buffer body 26 can be adjusted in the axial direction of the elastic body 22 and in the direction intersecting the axial direction.

[0018] 2 to 5 and 7, the storage box 10 is provided with a second buffer body (second buffer body) 30, which is provided on the storage body 12 and comes into contact with the elastic body 22 when the lid body 16 is in the open position, in addition to the first buffer body 26 described above. The second buffer body 30 in the embodiment is provided on the right side surface of the storage body 12 in correspondence with the elastic body 22. More specifically, the second buffer body 30 is attached to a second base portion 32 which is integrally formed with the storage body 12 so as to protrude from the right side surface.

[0019] As shown in FIG. 3, the second buffer 30 of the embodiment is disposed so as to abut against the coil portion 22a of the elastic body 22 when the lid body 16 is in the open position. More specifically, the second buffer 30 is formed narrower than the axial length of the coil portion 22a and disposed so as to abut against the axial center portion of the coil portion 22a. The second buffer 30 is disposed so as to overlap a part of the elastic body 22 when the lid body 16 is in the open position (see FIG. 7). The second buffer 30 of the embodiment is formed with a thickness of about 5 mm as a whole, and a part of the second buffer 30, about 1 mm to 2 mm, is set so as to interfere with the elastic body 22 when the lid body 16 is in the open position.

[0020] As shown in FIG. 3, the second abutment surface (abutment surface) 30a of the second buffer 30 with the elastic body 22 is disposed on the opposite side of the movement direction of the elastic body 22 displaced with the closure of the lid body 16 with respect to the elastic body 22 in the open position of the lid body 16. The second abutment surface 30a extends rearward from top to bottom in accordance with the elastic body 22 inclined rearward from top to bottom in the open position of the lid body 16. As shown in FIG. 7, the second abutment surface 30a is configured to move in the opposite direction to the movement direction of the elastic body 22 displaced with the closure of the lid body 16 as it moves away from the storage body 12. The second abutment surface 30a of the embodiment is inclined obliquely from between the elastic body 22 in the open position of the lid body 16 and the right side surface of the storage body 12 toward the opposite direction to the movement direction of the elastic body 22 displaced with the closure of the lid body 16. The second contact surface 30a in the embodiment is set to contact between the coil portion 22a on the side of the storage body 12 and the side opposite to the moving direction of the elastic body 22 displaced with the closure of the lid body 16. In the embodiment, the second mounting surface 32a to which the second buffer body 30 is attached in the second base portion 32 is formed to be inclined from between the right side surface of the storage body 12 and the elastic body 22 in the open position of the lid body 16 toward the opposite side to the moving direction of the elastic body 22 when the lid body 16 is displaced to the closed position. The posture of the second contact surface 30a is determined by mounting the second buffer body 30 in the shape of a rectangular block to such a second mounting surface 32a. The second mounting surface 32a is formed wider than the second buffer body 30, so that the mounting position of the second buffer body 30 can be adjusted in the axial direction of the elastic body 22 and in the direction intersecting the axial direction.

[0021] The first buffer 26 and the second buffer 30 are preferably made of a material having elasticity. Materials that can be used to form the first buffer 26 and the second buffer 30 include rubber, foam, nonwoven fabric, woven fabric, leather, etc., and in this embodiment, rubber sponge is used. The first buffer 26 and the second buffer 30 may be made of the same material or different materials.

[0022] In the storage box 10, the elastic body 22, which is installed between the right arm 14 and the right side surface of the storage body 12, is in a first state in which it is most contracted when the lid body 16 is in the intermediate position. In addition, the storage box 10 is configured so that the elastic body 22 is in a second state in which it is more extended than the first state between the intermediate position and the open position of the lid body 16, and between the intermediate position and the closed position. This helps the lid body 16 to open smoothly when the lid body 16 moves from the closed position to the open position, by changing from the extended state to the most contracted state in the initial stage when the lid body 16 starts to open. Then, when the lid body 16 passes the intermediate position and faces downward and its own weight becomes large, the elastic body 22 is in a state of being extended as it moves toward the open position, so that the lid body 16 is decelerated and prevented from opening forcefully. This improves the texture of the lid body 16 when it opens. In addition, when the lid body 16 moves from the open position to the closed position, the elastic body 22 contracts from an expanded state in the initial stage of the lid body 16 closing, thereby reducing the burden on the user who is supporting the lid body 16. Then, just before the lid body 16 passes the intermediate position and reaches the closed position, the elastic body 22 expands from a contracted state, allowing the lid body 16 to be closed slowly. This improves the texture of the lid body 16 when it is closed.

[0023] When the lid 16 of the storage box 10 is in the closed position, the elastic body 22, which is installed between the arm 14 supporting the lid 16 and the storage body 12, comes into contact with the first buffer body 26. In this way, the elastic body 22 comes into contact with the first buffer body 26, so that the first buffer body 26 can prevent the elastic body 22 from resonating due to vibrations from the driving engine or when the vehicle is traveling. This makes it possible to prevent the generation of abnormal noise due to the resonance of the elastic body 22, and damage to the elastic body 22 itself due to the resonance of the elastic body 22.

[0024] When the lid 16 of the storage box 10 is in the open position, the elastic body 22, which is installed between the arm 14 supporting the lid 16 and the storage body 12, comes into contact with the second buffer body 30. In this way, the elastic body 22 comes into contact with the second buffer body 30, and the second buffer body 30 can prevent the elastic body 22 from resonating due to vibrations of a driving engine or the like. This makes it possible to prevent the generation of abnormal noise due to the resonance of the elastic body 22 and damage to the elastic body 22 itself due to the resonance of the elastic body 22.

[0025] For example, a structure for fitting a tube to the outside of the coil portion 22a of the elastic body 22, or a structure for inserting a tube or the like into the inside of the coil portion 22a of the elastic body 22, can be considered as a countermeasure against resonance. Unlike the above-mentioned countermeasure against resonance, according to the above-mentioned resonance prevention structure of the elastic body 22, when the cover 16 is opened or closed, the first buffer body 26 and the second buffer body 30 move away from the elastic body 22, so that the spring constant of the elastic body 22 is not affected. Similarly, unlike the above-mentioned countermeasure against resonance, according to the above-mentioned resonance prevention structure of the elastic body 22, when the cover 16 is opened or closed, the first buffer body 26 and the second buffer body 30 move away from the elastic body 22, so that the opening and closing operation of the cover 16 is not affected. The above-mentioned resonance prevention structure of the elastic body 22 only requires that the buffer body 26 (30) is abutted against the elastic body 22, so that the degree of freedom in the arrangement of the buffer body 26 (30) is high, and by adjusting the abutment position, abutment range, etc., a countermeasure against resonance appropriate for the elastic body 22 can be easily and inexpensively implemented.

[0026] The first contact surface 26a of the first buffer 26 is configured to face the opposite direction to the movement direction of the elastic body 22 that is displaced with the opening of the lid 16 as it moves away from the storage main body 12. By inclining the first contact surface 26a in this manner, when the lid 16 is in the closed position, it is possible to prevent resonance in the left-right direction of the elastic body 22 and resonance in the up-down direction of the elastic body 22 with one first buffer 26. Moreover, in the embodiment, when the lid 16 is in the closed position, the first buffer 26 is located obliquely below the elastic body 22 that is inclined downward from the front side to the rear, so that it is possible to prevent three-dimensional resonance of the elastic body 22 including the front-rear direction with one first buffer 26.

[0027] The second contact surface 30a of the second buffer body 30 is configured to face the opposite direction to the movement direction of the elastic body 22 that is displaced with the closure of the lid body 16 as it moves away from the storage body 12. By inclining the second contact surface 30a in this manner, when the lid body 16 is in the open position, it is possible to prevent resonance in the left-right direction of the elastic body 22 and resonance in the up-down direction of the elastic body 22 with one second buffer body 30. Moreover, in the embodiment, when the lid body 16 is in the open position, the second buffer body 30 is located obliquely above the elastic body 22 that is inclined downward from the front side to the rear side, so that three-dimensional resonance of the elastic body 22 including the front-rear direction can be prevented with one second buffer body 30.

[0028] The first buffer 26 and the second buffer 30 are formed of an elastic material. This makes it possible to prevent the elastic body 22 from being damaged when the first buffer 26 (second buffer 30) and the elastic body 22 come into contact with each other. In addition, the first buffer 26 (second buffer 30) can softly receive the elastic body 22, thereby making it possible to prevent the generation of abnormal noise.

[0029] The first buffer body 26 and the second buffer body 30 are disposed so as to abut on the axial center portion of the coil portion 22a of the elastic body 22. In this manner, the first buffer body 26 (second buffer body 30) which is relatively narrow can effectively prevent the elastic body 22 from resonating.
