Description

  The present invention relates to a structure in which a torsion spring having a helical coil portion and two arm portions extending tangentially from both ends of the coil portion is attached between two members.

  Conventionally, there is one in which a torsion spring is installed between two members to improve its operability. Specifically, in the open / close door and the open / close lid, a structure in which a torsion spring is installed between the open / close door and the member that supports the open / close door and the door or the cover is urged in the opening direction or the closing direction. Is adopted.

  For example, an ashtray for a vehicle described in Patent Document 1 includes an outer case of an ashtray having an upper opening, and a lid that rotates with respect to a support shaft attached to the outer case to open and close the opening of the outer case. I have. A coil spring (torsion spring) is installed between the mounting hole formed in the lid and the mounting shaft formed in the outer case, so that the lid is biased in both the opening direction and the closing direction. It is configured to be.

JP 2003-24039 A

  By the way, in the vehicle ashtray described in Patent Document 1, when the ring portion 105 of the second arm portion 103 is loosely fitted to the mounting shaft 115, the coil arm 100 has the first arm portion 102 and the second ashtray. The second arm portion 103 is rotated around the coil portion 101 so that the “V” shape formed by the second arm portion 103 is closed. In this state, the ring portion 105 of the second arm portion 103 of the coil spring 100 is pressed against the outer case 110 side. That is, the ring portion 105 of the second arm portion 103 is loosely fitted to the mounting shaft 115 while restricting its position in the two directions of the “V” -shaped opening / closing direction of the coil spring 100 and the axial direction of the coil portion 101. It has to leave a problem in its workability.

  The present invention has been made in view of such circumstances, and its purpose is to provide a torsion that can be easily attached to the torsion spring when the torsion spring is installed between the first member and the second member. It is to provide a spring mounting structure.

  In order to achieve the above object, the invention according to claim 1 includes a spiral coil portion, a first arm portion extending in a tangential direction from one end of the coil portion, and a tangent line from the other end of the coil portion. A torsion spring having a second arm portion extending in a direction and having an end portion bent in a substantially axial direction of the coil portion, and a locking portion for rotatably locking the end portion of the first arm portion. In the state where the first member having the end portion of the first arm portion is locked, the second member centering on the coil portion by loosely fitting with the end portion of the second arm portion. A second member having a notch for restricting the rotation of the arm, and the end of the second arm in the state where the end of the first arm is locked. A first restricting surface that restricts the end of the second arm portion from being displaced in one of the axial directions of the coil portion when loosely fitting to the coil portion; And a guide portion that extends from the entrance of the notch portion and has a second restriction surface that restricts rotation of the second arm portion in one direction around the coil portion. And

  In the above configuration, the second arm is brought into contact with the first restriction surface of the guide portion in a state where the end portion of the first arm portion is locked to the locking portion. Displacement in one axial direction of the end coil portion of the portion is restricted, and the end portion of the second arm portion is positioned with respect to the notch portion in the axial direction of the coil portion. Further, the end of the second arm portion is brought into contact with the second restriction surface of the guide portion, thereby restricting the one-way rotation of the second arm portion around the coil portion. Then, when the second arm portion is slid toward the notch in a state where the second arm portion is in contact with the first and second regulating surfaces, the rotation of the second arm portion in one direction around the coil portion is performed. In a state where the movement is restricted by the second restriction surface, the coil portion and the second arm portion rotate relative to each other. And after the edge part of a 2nd arm part is guide | induced to the entrance of a notch part by the 2nd control surface extended from the entrance of a notch part, a coil part rotates a 2nd arm part. The end of the second arm is biased in the direction in which the notch is located by the restoring force, and the end of the second arm and the notch are loosely fitted. In other words, when the torsion spring is attached, if the second arm portion is brought into contact with the first and second regulating surfaces of the guide portion, the second arm portion becomes a notch portion with respect to the torsion spring. The end of the second arm and the notch are loosely fitted only by applying a force in one direction that slides in the direction.

  In this manner, the position of the end of the second arm can be easily regulated in the two directions with the torsion spring locked to the locking portion of the first member. The end portion of the second arm portion and the notch portion can be easily loosely fitted by a simple method in which the arm portion is brought into contact with the respective regulating surfaces and slid.

  According to a second aspect of the present invention, in the first aspect of the present invention, the guide portion is centered on the coil portion in a state in which the end portion of the second arm portion and the notch portion are loosely fitted. The gist of the present invention is that a third restricting surface for restricting the rotation of the second arm portion in one direction is provided.

  In the above configuration, the third restriction surface restricts the rotation of the second arm part in one direction, so that the notch part is loosely fitted with the notch part. Since the rotation of the second arm portion in one direction can be restricted by a portion other than the portion, the posture of the torsion spring is stabilized. In addition, you may make it form this 3rd control surface continuously on the wall surface which makes the outline of a notch part, for example.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the second restricting surface rises as it approaches the entrance of the notch at a portion near the first restricting surface. The gist is that the inclined surface is formed.

  In the above configuration, when the second arm portion is brought into contact with the second restriction surface and slid, the frictional force generated between the end portion of the second arm portion and the second restriction surface; Since the force for sliding the second arm portion acts on the torsion spring, the entire torsion spring may be inclined. In this regard, according to the above configuration, near the entrance of the notch, the portion of the end of the second arm portion near the first restriction surface is more relative to the second restriction surface than the second restriction surface. Therefore, the occurrence of such inclination is suppressed. In addition, since such an inclined surface is provided, the second arm portion is unlikely to be detached from the notch in a state where the end of the second arm is loosely fitted with the notch. Effects can also be achieved.

The gist of the invention according to claim 4 is that, in the invention according to any one of claims 1 to 3, the guide portion and the second member are integrally formed.
As described above, if the second member and the guide portion are integrally formed, the number of parts can be reduced, and the step of fixing the guide member to the second member can be omitted.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the second member is configured by a housing having an opening, and the first member is mounted on the housing. On the other hand, the gist of the invention is that the cover is configured to be pivotably supported via a pivot shaft and to open and close the opening.

In the above configuration, the torsion spring is attached between the second member having the housing and the lid, and the opening and closing of the lid is urged by the torsion spring.
The invention according to claim 6 is the invention according to any one of claims 1 to 4, wherein the second member includes a housing having an opening, and the first member is And two lids that open and close the opening by pivoting in opposite directions via a pivot shaft, and the torsion springs are substantially in the same direction between the housing and the lids. The main point is that

  In said structure, since the torsion spring is constructed in the substantially the same direction with respect to each cover body, the same torsion spring can be used.

  According to the torsion spring mounting structure of the present invention, in the state where the torsion spring is locked to the locking portion of the first member, the two arm portions of the end portion of the second arm portion are moved by the respective restricting surfaces of the guide portion. Since the position can be easily regulated, the end portion of the second arm portion can be easily loosely fitted to the notch portion.

Here, in this embodiment, since the inclined surfaces 75 and 79 are formed on the second restricting surfaces 73 and 77, the torsion springs 80 and 90 maintain a stable posture without being inclined, It approaches the notches 60 and 61. That is, when the arm main body portions 87 and 97 of the second arm portions 83 and 93 are pressed toward the cutout portions 60 and 61, the pressing force and the second arm portions 83 and 93 and the second restriction surface are pressed. May cause the torsion springs 80 and 90 to tilt so that the end portions of the arm main body portions 87 and 97 on the first bent portions 84 and 94 side enter the inside (right side) of the cup holder 20. There is. Therefore, in the present embodiment, by providing such inclined surfaces 75 and 79, the arm main body portions 87 and 97 side of the first bent portions 84 and 94 are gradually raised upward as they approach the notches 60 and 61. Such an inclination is suppressed by lifting.

  The torsion springs 80, 90 are provided as one of the second arm portions 83, 93 centered on the coil portions 81, 91 as the end portions of the second arm portions 83, 93 approach the notches 60, 61. In a state where the rotation of the direction is regulated by the second regulating surfaces 73 and 77, the coil parts 81 and 91 and the second arm parts 83 and 93 are in a direction in which the “V” shape of the torsion springs 80 and 90 is closed Relative rotation. As a result, a restoring force is applied to the torsion springs 80 and 90 to open the “V” shape and return to the normal state. Then, the second arm surfaces 83 and 93 of the torsion springs 80 and 90 are notched at the notches 60 and 61 by the second restricting surfaces 73 and 77 extending from the inlets 60a and 61a of the notches 60 and 61. Then, the ends of the second arm portions 83 and 93 are urged downward by the restoring force of the torsion springs 80 and 90. Thereby, the edge part of the 2nd arm parts 83 and 93 of the torsion springs 80 and 90 and the notch parts 60 and 61 are loosely fitted. In this loosely fitted state, the first bent portions 84 and 94 are sandwiched between the front and rear side surfaces of the cutout portions 60 and 61 forming the “U” shape, and the side panels 51 a and 52 a of the retainers 51 and 52. Is sandwiched between the arm main body portions 87 and 97 of the second arm portions 83 and 93 and the second bent portions 85 and 95.

  Further, in this state, the outer side (left side) of the first bent portions 84 and 94 of the second arm portions 83 and 93 is formed by the third restriction surfaces 74 and 78 that are continuous with the side surfaces of the cutout portions 60 and 61. The torsion springs 80 and 90 are restricted from rotating in the closing direction, and the torsion springs 80 and 90 are allowed to rotate in a state where the second arm part is loosely fitted with the notch. It is suppressed. Furthermore, since the inclined surfaces 75 and 79 are formed on the second restricting surfaces 73 and 77, the height of the third restricting surfaces 74 and 78 is also high in the portion corresponding to the second restricting surfaces 73 and 77. Thus, the end portions of the second arm portions 83 and 93 are difficult to be detached from the cutout portions 60 and 61.

As described above in detail, according to this embodiment, the following effects can be obtained.
(1) In the cup holder 20 of the present embodiment, the second arm portion in a state where the first arm portions 82 and 92 of the torsion springs 80 and 90 are engaged with the through holes 48 and 49 of the lids 41 and 42. When the end portions of 83 and 93 are loosely fitted into the cutout portions 60 and 61 of the retainers 51 and 52, guide portions 70 and 71 for regulating the position of the torsion spring are provided. The guide portions 70 and 71 are separated from the first restricting surfaces 72 and 76 that restrict the end portions of the second arm portions 83 and 93 from being displaced in one of the coil portions 81 and 91 in the axial direction. Second restricting surfaces 73 and 77 extending from the inlets 60a and 61a of the notches 60 and 61 and restricting the rotation of the second arm portions 83 and 93 around the coil portions 81 and 91 in one direction; have. Therefore, when the end portions of the second arm portions 83 and 93 are brought into contact with the first restricting surfaces 72 and 76 and the second restricting surfaces 73 and 77, the end portions of the second arm portions 83 and 93 are coiled. It can be maintained at a position corresponding to the cutout portions 60 and 61 in the axial direction of the portions 81 and 91. In this state, when the second arm portions 83 and 93 are slid toward the cutout portions 60 and 61, the rotation of the second arm portions 83 and 93 around the coil portions 81 and 91 in one direction is performed. In a state where the movement is regulated by the second regulating surfaces 73 and 77, the coil portions 81 and 91 and the second arm portions 83 and 93 are relatively rotated in the direction in which the “V” shape of the torsion springs 80 and 90 is closed. To do. Thus, when the end portions of the second arm portions 83 and 93 reach the inlets 60a and 61a of the cutout portions 60 and 61, the ends of the second arm portions 83 and 93 are restored by the restoring force of the torsion springs 80 and 90. The portion is urged downward and loosely fits with the notches 60 and 61.

  Thus, in the state where the first arm portions 82 and 92 of the torsion springs 80 and 90 are locked, the position restriction in the two directions of the end portions of the second arm portions 83 and 93 is restricted. 71 can be easily performed. Therefore, when the torsion springs 80 and 90 are attached, if the second arm portions 83 and 93 are brought into contact with the guide portions 70 and 71, the second arm portions 83 and 93 are formed in the cutout portions 60 and 61. The end portions of the second arm portions 83 and 93 and the cutout portions 60 and 61 can be loosely fitted only by applying a force for sliding in the direction.

  (2) In the cup holder 20 of the present embodiment, in the state where the guide portions 70 and 71 are loosely fitted between the end portions of the second arm portions 83 and 93 and the notches 60 and 61, the coil portions 81 and 91 are Third restriction surfaces 74 and 78 are provided for restricting the “V” shape of the second arm portions 83 and 93 at the center from rotating in the closing direction. Thereby, it is possible to prevent the torsion springs 80 and 90 from being twisted in a state where the second arm portions 83 and 93 are loosely fitted to the notches 60 and 61, and the posture can be stabilized.

  (3) In the cup holder 20 of the present embodiment, as the second restriction surfaces 73 and 77 of the guide portions 70 and 71 approach the first restriction surfaces 72 and 76 and approach the entrances of the cutout portions 60 and 61. Raised inclined surfaces 75 and 79 are formed. Accordingly, the end portions of the second arm portions 83 and 93 of the torsion springs 80 and 90 are brought into contact with the first restriction surfaces 72 and 76 and the second restriction surfaces 73 and 77 of the guide portions 70 and 71. It is possible to prevent the torsion springs 80 and 90 from tilting when sliding.

  (4) In the cup holder 20 of the present embodiment, the front lid 41 and the rear lid 42 rotate in opposite directions with respect to the casing 21, but the torsion springs 80 and 90 both have a “V” shape in the rear. They are attached in substantially the same direction in such a manner that they open toward. Therefore, the same torsion spring can be used, and it is not necessary to prepare two types of springs in which the spirals of the coil portions are wound in opposite directions as parts of the cup holder 20.

Note that the present invention can be embodied in another embodiment described below.
In the above embodiment, the second restricting surfaces 73 and 77 of the guide portions 70 and 71 restrict the rotation of the second arm portions 83 and 93 in one direction. Although the rotation of the “V” of the torsion spring is restricted in the opening direction, the restricted one direction may be the opposite direction. That is, the second arm portion may be restricted from rotating in the direction in which the “V” shape of the torsion spring is closed. Moreover, in the said embodiment, the edge part of the 2nd arm parts 83 and 93 moves to the outer side (left side) rather than the cup holder 20 in the axial direction of the coil parts 81 and 91 by the 1st control surfaces 72 and 76. However, the movement to the inside (right side) of the cup holder 20 may be restricted.

  FIG. 6 shows an example in which the first restriction surface and the second restriction surface of the guide portion restrict the movement of the second arm portion in the direction opposite to that of the above embodiment. As shown in FIG. 6, a substantially “U” -shaped notch 65 that opens downward is formed at the rear end of the side panel 64a in the intermediate portion 64 of the rear retainer 62. The retainer 62 is fixed with a guide portion 66 extending from the portion where the notch portion 65 is formed toward the rear of the vehicle. The guide portion 66 has a second restriction surface 68 extending rearward and upward from the inlet 65a of the cutout portion 65, and a second restriction surface 68 extending vertically downward from a portion on the right side of the second restriction surface 68. 1 restriction surface 67. The second restricting surface 68 is in a state where the end of the first arm portion 92 of the torsion spring 90 penetrates the through hole 49 and a force for opening and closing the “V” shape does not act on the torsion spring 90. It inclines sharply downwardly toward the notch 65 side from the locus of the circular arc drawn by the end of the arm portion 93. When the second bent portion 95 and the first bent portion 94 of the second arm portion 93 of the torsion spring 90 are brought into contact with the first and second restricting surfaces 67 and 68, respectively, the coil portion 91 is obtained. The positions of the end portion of the second arm portion 93 and the notch portion 65 substantially coincide with each other in the axial direction. In this state, when the torsion spring 90 is slid in the direction of the arrow in FIG. 6, the second arm portion 93 is moved to the coil portion 91 as the end portion of the second arm portion 93 approaches the inlet 65a of the notch portion 65. The “V” shape of the torsion spring 90 is rotated in the opening direction. When the end portion of the second arm portion 93 reaches the notch portion 65, the end portion of the second arm portion is moved upward by a restoring force for closing the “V” shape of the torsion spring 90. It is urged and the notch 65 is loosely fitted. Even with such a configuration, the position of the end portion of the second arm portion 93 of the torsion spring 90 in two directions can be restricted, so that the torsion spring 90 can be easily attached to the notch portion 65.

  The first restriction surface is formed so as to extend in the vertical direction from the second restriction surface, and the first restriction surface and the second restriction surface are connected. The second restricting surface only needs to be able to restrict the movement of the second arm portions 83 and 93 in two directions, and the first restricting surface and the second restricting surface may have no contact. That is, in each of the above embodiments, the corner portion between the arm main body portions 87 and 97 of the second arm portions 83 and 93 of the torsion springs 80 and 90 and the first bent portions 84 and 94 is the first restriction. The movement of the second arm portion is restricted by fitting in a corner formed by the surface and the second restriction surface. However, the guide part, for example, abuts only the intermediate part of the first bent parts 84 and 94 and the first restricting surface that restricts the movement by abutting only the intermediate part of the arm main body parts 87 and 97. It may be configured to have a second restriction surface that restricts the movement.

  In each of the above embodiments, the locking portion provided on the lid is configured with a through hole, but other shapes may be used as long as the first arm portion can be pivotally supported instead of the through hole. It may be of a shape. Further, the shape of the cutout portion provided in the retainer is not limited to the shape of each of the above embodiments, and may be, for example, a “V” shape, or the side panel of the retainer has a “U” shape cutout portion. A "U" shape that is slightly larger than the notch may be formed around the periphery of the notch and may be formed in a hook-like shape.

  In the above embodiments, the front and rear lids are rotated in opposite directions with respect to the housing, but the front and rear torsion springs are attached in substantially the same direction. However, the rear side torsion spring is mounted in such a manner as shown in FIGS. 3 to 7 so that the “V” shape is opened rearward, and the front side torsion spring is the embodiment shown in FIGS. 3 to 7. You may attach so that a "V" character may open toward the front in a different aspect. In this case, the front and rear torsion springs have symmetrical shapes. In this case, the side panel of the front retainer is formed with a notch in the front portion, and the guide portion extends forward from a portion corresponding to the notch in the retainer.

  In the above embodiments, the two torsion springs are both attached to the left side of the cup holder. However, for example, only the front torsion spring may be attached to the right side of the cup holder. In such a case, if the “V” shape of the front torsion spring is installed so as to open toward the front, the torsion spring having the same shape as the rear side torsion spring 90 shown in FIGS. Can do.

  -In each above-mentioned embodiment, although cup holder 20 was provided with two lids 41 and 42, one lid may be sufficient. Further, even when two lids are provided, these lids may be rotated in the same direction when opened and closed. Furthermore, as another example of the case where the two lids rotate in the opposite directions, the front lid is pivotally supported by the housing at the rear portion thereof and is opened and closed forward, and the rear lid is moved forward. It is also possible to pivotally support at this part and to open and close backward.

  Moreover, in the cup holder 20 of each said embodiment, the space inside the holder parts 31 and 32 does not need to be connected by the groove | channel 33a of the connection part 33. FIG. In this case, the two openings 34 and 35 are the openings described in claim 6.

  In each of the above embodiments, the torsion spring mounting structure is applied to a vehicle cup holder. For example, it has a lid as a first member and a housing as a second member, such as a dust box and an ashtray. You may apply to other things. Further, the first member and the second member to which the torsion spring is attached may be other than the lid and the housing.
