The shaft member 30 is disposed substantially horizontally with respect to the vehicle bottom surface (not shown).

  A leaf spring 50 is attached to one of the arms 22 and the base 12 that is positioned on the distal end side of the shaft portion of the shaft member 30, in this embodiment, the base 12. Referring to FIGS. 2 and 3 together, the leaf spring 50 is formed by appropriately bending a metal plate extending in a strip shape with a predetermined width, and includes a base 51 and the base 12 on both sides of the base. And a pair of side portions 52 and 53 which are bent so as to sandwich them.

  One side portion 52 is disposed in contact with the inner surface of the base 12 on the tip end side of the base 12 and is fitted in the annular groove 33a of the shaft portion 33 at the center in the width direction and with a predetermined length from the tip in the extending direction. A first slit 54 is provided. On both sides of the first slit 54 on the inlet side, chamfered portions 54a and 54a for insertion guides of the shaft portion 33 are formed. Further, on both sides of the first slit 54 of the side portion 52, locking projections 55 and 55 cut inward toward the other side portion 53 are provided via a U-shaped slit 55 a. The locking projections 55 and 55 are portions that engage with the concave portions 16 and 16 on the upper side of the inner surface of the base 12.

  The other side portion 53 has a second slit 57 into which the shaft portion 33 is inserted from the tip in the extending direction to a position slightly beyond the middle in the center in the width direction. In addition, sandwiching portions 59 and 59 that contact the outer surface of the base 12 are formed on both sides of the distal end portion divided by the second slit 57 of the side portion 53, and the base portion side of the side portion 53 is also on the base side. The clamping part 61 which contact | abuts to the outer surface of 12 is formed. Note that the front end portions 59 a and 59 a of the holding portions 59 and 59 on the front end side of the side portion 53 are folded back obliquely toward the arm 22.

  In addition, inclined portions 63 and 63 extend obliquely from the sandwiching portions 59 and 59 toward the arm 22, and an inclined portion 65 extends obliquely toward the arm 22 from the sandwiching portion 61. Yes.

  The portions between the holding portions 59, 59, and 61 bulge toward the arm 22 through the bent portions 67, 67 at the tip of each inclined portion 63 and the bent portion 69 at the tip of the inclined portion 65. A pressing portion 70 is formed that is bent in a gate shape, is parallel to the one side 52 and has a wide shape, and is pressed against the arm 22.

  Next, the usage method and the effect of the support structure for the accessory case for the vehicle according to the present invention will be described.

  First, the arms 22 and 22 of the lid 20 are arranged outside the bases 12 and 12 of the accessory case 10, and the shaft holes 12a and 22a of both members are aligned (see FIG. 4A). In that state, the shaft portion 33 of the shaft member 30 is inserted from the outer surface side of the arm 22, the head portion 31 is engaged with the outer surface of the arm 22, and the tip of the shaft portion 33 is inserted from the shaft hole 12a through the shaft hole 22a. The arm 22 is rotatably supported with respect to the base 12 (see FIG. 4B).

  Thereafter, as shown in FIG. 4B, one side portion 52 of the leaf spring 50 is disposed on the inner surface side of the base 12, while the other side portion 53 is disposed on the outer surface side of the base 12. The slit 57 is aligned with the insertion guide convex portion 14 of the base 12. In this state, the tip of the side portion 53 is inserted into the gap between the base 12 and the arm 22, and the leaf spring 50 is pushed in from below the base 12 while the base 12 is sandwiched between the side portions 52 and 53.

  Then, while the other side 53 is guided by the insertion guide convex portion 14 inserted into the second slit 57, the shaft portion 33 is inserted into the second slit 57 while being bent and deformed. . Then, the first slit 54 of the one side portion 52 is fitted into the annular groove 33a of the shaft portion 33, and the locking projections 55, 55 are respectively engaged with the concave portions 16, 16 on the inner surface of the base 12. Thus, the leaf spring 50 can be attached to the base 12 (see FIGS. 5 and 6).

  At this time, the insertion work of the leaf spring 50 is improved because the insertion work of the side part 53 into the gap between the base 12 and the arm 22 is guided by the insertion guide convex part 14 provided on the base 12. Further, since the front end portions 59a and 59a of the clamping portions 59 and 59 on the front end side of the side portion 53 are folded back obliquely toward the arm 22, it becomes easy to insert into the gap between the base 12 and the arm 22, and the insertion work Improve sexiness. Further, when the leaf spring 50 is attached to the base 12, the base portion 51 of the leaf spring 50 comes into contact with the step portion 13 provided below the base 12 (see FIG. 6). Can be attached firmly without sticking.

  Furthermore, in this embodiment, as described above, the locking protrusion 55 of the leaf spring 50 engages with the recess 16 on the inner surface of the base 12 to restrict the movement of the leaf spring 50, so that even if the lid 20 rotates. The leaf spring 50 is prevented from moving, and the rotation restriction on the lid 20 can be made more reliable. Further, it is possible to prevent the leaf spring 50 from coming off from one member and coming off.

  The leaf spring 50 can be attached to the base 12 as shown in FIG. That is, the base 12 is sandwiched between the side portions 52 and 53 of the leaf spring 50, and the leaf spring 50 is pushed in so that the inlet portion of the first slit 54 and the second slit 57 are aligned with the shaft hole 12a of the base 12. Then, the leaf spring 50 is temporarily held on the base 12 (see FIG. 7A).

  In this state, the arms 22 and 22 of the lid 20 are disposed outside the bases 12 and 12, the shaft holes 12a and 22a are aligned, and the shaft portion 33 of the shaft member 30 is inserted from the outer surface side of the arm 22, The head 31 is engaged with the outer surface 22, the shaft portion 33 is passed through the shaft hole 22 a, the second slit 57, and the shaft hole 12 a, and the tip of the shaft portion 33 is inserted from the inlet portion of the first slit 54, thereby The arm 22 is rotatably supported with respect to 12 (see FIG. 7B).

  Next, by pushing up the leaf spring 50 upward, the first slit 54 is fitted into the annular groove 33a of the shaft portion 33, and the locking projections 55, 55 are engaged with the recesses 16, 16 above the inner surface of the base 12, respectively. Then, the leaf spring 50 can be attached to the base 12 as shown in FIG.

  When the leaf spring 50 is attached to the arm 22 as described above, the other side portion 53 of the leaf spring 50 is inserted between the arm 22 and the base 12 as shown in FIG. , 59 and 61 are in contact with the outer surface of the arm 22 and the pressing portion 70 is pressed against the pressing convex portion 25 on the inner surface of the arm 22, so that a frictional force can be applied to the rotation operation of the arm 22 and the base 12. it can. As a result, when the lid 20 is opened and disposed at a predetermined angle, the lid 20 can be held at that angle by the frictional force (so-called free stop is possible).

  Further, since the first slit 54 of the side portion 52 of the leaf spring 50 is fitted into the annular groove 33a of the shaft portion 33 and the shaft member 30 is prevented from coming off, the shaft member 30 is fixed to the C ring or E ring, It is not necessary to prevent the nut from being detached, and the workability of attaching the leaf spring 50 can be improved.

  Further, when the arm 22 of the lid 20 is pivotally supported by the base 12 of the accessory case 10, the arm supporting convex portion 15 on the outer surface of the base 12 enters the concave portion 24 on the inner surface of the arm 22 ( 1 and 6). Therefore, for example, even when an external force acts on the lid 20 and the arm 22 is pushed into the base 12, the arm support convex portion 15 can suppress the pushing of the arm 22, and the side portion 53 of the leaf spring 50. Can be prevented from being excessively crushed, and the pressing force of the pressing portion 70 against the arm 22 can be maintained at a predetermined value.

  The leaf spring 50 in this embodiment is mounted on the base 12 so that the wide surface of the pressing portion 70 is aligned along the extending direction of the base 12 (see FIGS. 1 and 5). Then, as shown in FIG. 8A, when the lid 20 has an angle close to horizontal, the pressing convex portion 25 on the inner surface of the tip end of the arm 22 abuts on one side in the width direction of the pressing portion 70 of the leaf spring 50. (The contact area of the pressing portion 70 with respect to the arm 22 at this time is S). On the other hand, as shown in FIG. 8B, when the lid 20 is at an angle close to vertical, the pressing convex portion 25 is the pressing portion. The pressing portion 70 is not in contact with 70, but is in contact with the recess 24 (see FIG. 1) of the arm 22. As a result, the pressing force on the arm 22 of the pressing portion 70 of the leaf spring 50 is increased when the lid 20 has an angle close to horizontal compared to when the lid 20 has an angle close to vertical. Yes.

  Therefore, when the lid 20 has an angle close to the horizontal, the rotational moment due to the gravity of the lid 20 increases, but the pressing force of the leaf spring 50 against the arm 22 of the pressing portion 70 increases, so the frictional force increases and the rotation is restrained. The force can be increased, and the lid 20 can be stopped at a desired opening angle. On the other hand, when the lid 20 has an angle close to vertical, the rotational moment due to the gravity of the lid 20 is reduced, but the pressing force of the leaf spring 50 against the arm 22 of the pressing portion 70 is reduced, so that the rotational stopping force due to the frictional force is also reduced. The frictional resistance when the lid 20 is rotated can be reduced while maintaining the frictional force that stops at the desired opening angle.

  FIG. 9 shows the rotational moment M due to the weight of the lid 20 from the state in which the lid 20 is horizontal and the opening 11 of the accessory case 10 is closed to the state in which the lid 20 is vertical and the opening 11 is completely opened. The relationship with the pressing force F with respect to the arm 22 of the press part 70 is shown. As shown in this figure, as the lid 20 is opened and its rotational moment M decreases, the pressing force F by the pressing portion 70 decreases to such an extent that the lid 20 does not close with its own weight. Further, when the lid 20 is opened and the pressing convex portion 25 of the arm 22 is detached from the bent portion 69 of the leaf spring 50 and does not come into contact with the pressing portion 70, the pressing force F is rapidly reduced (reference numeral). F1).

  10 to 13 show a second embodiment of a lid support structure for a vehicle accessory case according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 10, the leaf spring 50 a in this embodiment includes a groove of the annular groove 33 a of the shaft portion 33 in the middle portion of the first slit 54 formed with a predetermined length in the center in the width direction of the side portion 52. A reduced diameter portion 54b having an inner diameter smaller than the outer diameter at the bottom portion is formed. Further, the inner surface of the arm 22 has a shape in which the concave portion 24, the pressing convex portion 25, and the rotation guide convex portion 26 are not formed.

  Then, by pressing the leaf spring 50a laterally from the tip of the base 12 in the protruding direction, the other side portion 53 is inserted between the base 12 and the arm 22, and the shaft portion 33 is inserted into the first slit 54, The leaf spring 50 can be attached to the base 12 in a state where the reduced diameter portion 54b is passed through and press-fitted to prevent the shaft portion 33 from coming off (see FIGS. 11A and 11B).

  As described above, according to the leaf spring 50a of this embodiment, when the shaft portion 33 is pressed into the first slit 54 through the reduced diameter portion 54b, the reduced diameter portion 54b prevents the shaft portion 33 from coming off. The leaf spring 50a can be prevented from coming off the base 12 and coming off.

  The leaf spring 50a in this embodiment is mounted on the base 12 with the wide surface of the pressing portion 70 aligned with the direction orthogonal to the extending direction of the base 12 (see FIGS. 11A and 11B), and is flat. The inner surface of the distal end of the arm 22 is in direct contact with the pressing portion 70 so that a frictional force is applied to the turning operation of the arm 22.

  Then, as shown in FIG. 12A, when the lid 20 has an angle close to the horizontal, the inner surface of the distal end of the arm 22 comes into contact with a predetermined region of the pressing portion 70 of the leaf spring 50a, and in particular, each bent portion 67. , 69 strongly contact with each other (contact areas of the bent portions 67, 69 with respect to the arm 22 at this time are denoted as S1, S2). Then, as the lid 20 is opened, the contact area of the bent portions 67 and 69 fluctuates. As shown in FIG. 67 and 69 contact with a smaller contact area than the contact region in FIG. 12A (see S1 and S2). In other words, the contact area of the pressing portion 70 of the leaf spring 50a is increased when the lid 20 has an angle close to horizontal compared to when the lid 20 has an angle close to vertical.

  According to this aspect, when the lid 20 is at an angle close to the horizontal, the rotational moment due to the gravity of the lid 20 increases, but the contact area of the pressing portion 70 of the leaf spring 50a increases, so that the rotational stopping force due to the frictional force is reduced. It acts more effectively and can restrain the lid 20 at a desired opening angle. On the other hand, when the lid 20 is at an angle close to vertical, the rotational moment due to the gravity of the lid 20 is reduced, but the contact area of the pressing portion 70 of the leaf spring 50a is reduced, so that the rotational stopping force due to the frictional force is also reduced and desired. The frictional resistance when the lid 20 is rotated can be reduced while maintaining the frictional force that is restrained at the opening angle.

  FIG. 13 shows the rotational moment M due to the weight of the lid 20 from the state in which the lid 20 is horizontal and the opening 11 of the accessory case 10 is closed to the state in which the lid 20 is vertical and the opening 11 is completely opened. The relationship with the pressing force F with respect to the arm 22 of the press part 70 is shown. The figure also shows the variation of the pressing force G against the arm 22 when the structure of this embodiment is not employed and the conventional structure is tightened with bolts.

  As shown in FIG. 13, when the lid 20 is opened, its rotational moment M decreases. At first, the pressing force F by the pressing portion 70 is not different from the pressing force G. However, when the lid 20 is opened more than half, The pressure F suddenly decreases (see reference numeral F1), and the lid 20 can be opened with a force lighter than the pressing force G.

  FIGS. 14 to 16 show a third embodiment of a lid support structure for a vehicle accessory case according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 14, the leaf spring 50b in this embodiment has a structure in which both side portions 52 and 53 are formed wider than the leaf springs 50 and 50a in the first and second embodiments. That is, in both side parts 52 and 53, the width direction other side part is formed wider than the width direction one side part across the first slit 54 or the second slit 57. Note that the inner surface of the arm 22 has a shape in which the concave portion 24, the pressing convex portion 25, and the rotation guide convex portion 26 are not formed.

  And the leaf | plate spring 50b of this embodiment is mounted | worn with the base 12 so that the wide surface of the press part 70 may align along the extension direction of the base 12, like the leaf | plate spring 50 of 1st Embodiment, The inner surface of the distal end of the arm 22 is brought into contact with the pressing portion 70 so that a frictional force is applied to the rotation operation of the arm 22.

  At this time, as shown in FIG. 15A, when the lid 20 has an angle close to the horizontal, the inner surface of the tip of the arm 22 is a predetermined region of the pressing portion 70 of the leaf spring 50b, particularly the bent portions 67 and 69. It strongly abuts the periphery (contact areas of the bent portions 67 and 69 with respect to the arm 22 at this time are denoted as S1 and S2). When the lid 20 is opened, the contact area of the bent portions 67 and 69 changes. As shown in FIG. 15B, when the lid 20 has an angle close to vertical, the bent portions 67 and 69 are formed on the arm 22. , The contact area is smaller than the contact area in FIG. 15A (see S1 and S2). In other words, the contact area of the pressing portion 70 of the leaf spring 50b is increased when the lid 20 has an angle close to horizontal compared to when the lid 20 has an angle close to vertical.

  Similarly to the second embodiment, in this aspect, when the lid 20 has an angle close to the horizontal, the contact area of the pressing portion 70 increases, and the rotation stopping force due to the frictional force acts more effectively. On the other hand, when the lid 20 is at an angle close to vertical, the contact area of the pressing portion 70 is reduced, and the rotational stopping force due to the frictional force can be reduced, and the frictional resistance when the lid 20 is rotated is reduced. Can be reduced.

  FIG. 16 shows the rotational moment M due to the weight of the lid 20 from the state in which the lid 20 is horizontal and the opening 11 of the accessory case 10 is closed to the state in which the lid 20 is vertical and the opening 11 is completely opened. The relationship with the pressing force F with respect to the arm 22 of the press part 70 is shown. As shown in the figure, when the lid 20 is opened and the rotational moment M decreases, the pressing force F is flat at first, but when a part of the arm 22 is released from the bent portion 69, the pressing force F is flat. The pressure F decreases (see reference numeral F1), and the lid 20 can be opened with a light force.

  17 and 18 show a fourth embodiment of a lid support structure for a vehicle accessory case according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 17A and 17B, the leaf spring 50 c in this embodiment has clamping portions 59, 59 formed at the tip of the other side portion 53, and the inclined portion 63 extends from the clamping portion 59. , 63, a pressing portion 70 is formed so as to bulge toward the arm 22. Also, one side 52 is bent at a right angle from one side edge of the base 51 and the other side 53 from the other side edge of the base 51 is inclined inward so as to be close to the side 52. The pressing portion 70 is gradually protruded toward the base side (see FIG. 17A).

  As in the second embodiment, the leaf spring 50c is mounted laterally with respect to the base 12, and the inner surface of the tip of the arm 22 abuts against the pressing portion 70, so that frictional force is exerted on the turning operation of the arm 22. Is granted. At this time, the arm 22 strongly hits the highest protruding portion of the pressing portion 70.

  As shown in FIG. 18 (a), when the lid 20 has an angle close to horizontal, the tip of the arm 22 comes into strong contact with the highest portion of the pressing portion 70 of the leaf spring 50c, and a frictional force is applied. . Then, the lid 20 is opened, and as shown in FIG. 18 (b), when the lid 20 has an angle close to vertical, the vicinity of the side of the arm 22 is a portion where the protruding height of the pressing portion 70 is slightly lowered. Will come into contact. At this time, when the distance from the axis C1 of the shaft member 30 to the pressing portion contact position C2 of the arm 22 is L, the distance L in FIG. 18A is the distance L in FIG. Is farther than. Also, the pressing force is greater in FIG. 18A than in FIG. 18B. That is, the position C2 at which the arm 22 is pressed by the pressing portion 70 is more when the lid 20 is closer to the horizontal than when the lid 20 is closer to the vertical than the axis C1 of the shaft member 30. As the distance increases, the pressing force also increases.

  According to this, when the lid 20 has an angle close to horizontal, the rotational moment due to the gravity of the lid 20 increases, but the position C2 where the arm 22 is pressed by the pressing portion 70 of the leaf spring 50c is the axis of the shaft member 30. Since it becomes farther from the center C1 and the pressing force becomes stronger, the rotational stopping force due to the frictional force acts more effectively, and the lid 20 can be stopped at a desired opening angle. On the other hand, when the lid 20 is at an angle close to vertical, the rotational moment due to the gravity of the lid 20 is reduced, but the position C2 where the arm 22 is pressed by the pressing portion 70 of the leaf spring 50c is at the axis C1 of the shaft member 30. Since the pressure becomes closer and the pressing force becomes weaker, the rotational stopping force due to the frictional force is also reduced, and the frictional resistance when rotating the lid 20 can be reduced while maintaining the frictional force that stops at the desired opening angle.

  In the embodiment described above, “one member positioned on the tip end side of the shaft portion of the arm and the base” according to the present invention means the base 12, and “the other member”. Means the arm 22, the leaf spring 50 is attached to the base 12, and the shaft member 30 is inserted into each shaft hole from the outer surface of the arm 22. Not limited to this aspect, for example, “one member located on the tip end side of the shaft portion” is an arm, and “the other member” is a base, and a plate spring is attached to the arm. A shaft member may be inserted into the shaft hole.

  The durability test of the lid support structure according to the present invention was performed. That is, when the lid was opened and closed multiple times, the fluctuation of the frictional force caused by the leaf spring was measured to check whether the free stop function was maintained.

Example 1
The thing of 1st Embodiment of FIGS. 1-9 was used, and as shown in FIG. 6, the distance H of the base 12 outer surface and the press convex part 25 inner surface of the arm 22 was set so that it might be set to 7.6 mm.

(Example 2)
The same as Example 1 except that the distance H was set to 8.5 mm.

(Test method)
In Examples 1 and 2, the lid was rotated from the horizontal state to the vertical state and returned to the horizontal state, and this was performed as one opening / closing operation, and the lid was opened / closed a plurality of times (1 to 10,000 times). Fluctuations between the pressing force when the lid was fully opened and the pressing force when the lid was fully closed by the leaf spring at that time were measured. The result is shown in FIG.

(Test results)
As shown in FIG. 19, in both the first and second embodiments, even if the lid is opened and closed several times, the pressing force by the pressing portion can be maintained to the extent that the lid does not close due to its own weight, and the lid can be at any angle. It was found that it was possible to maintain a free stop function that could be maintained in

  Further, it is understood that the pressing force of Example 1 is higher than the pressing force of Example 2, and the pressing force is higher when the distance H between the outer surface of the base 12 and the inner surface of the pressing convex portion 25 of the arm 22 is smaller. did it. Furthermore, it was confirmed that the pressing force was higher when the lid was fully closed than when the lid was fully closed.
