Description

  The present invention relates to an urging body that is interposed between two members and prevents rattling or positioning between the members.

  2. Description of the Related Art Conventionally, in a glove box having a box body attached to an opening of an automobile instrument panel (hereinafter referred to as instrument panel) and a lid for opening and closing the box body, the glove box is elastically formed at the opening edge of the instrument panel. The thing which provided the convex part which contact | abuts in the both sides of a lid is known (refer patent document 1). The convex portions on both sides of the lid are realized as a resin piece integrally formed with a resin lid, or as a protruding portion of a leaf spring (spring material) having a base end attached to the lid. Thereby, the position of the lid in the left-right direction is corrected by the elastic force of the convex portion, and the gap between the lid side portions and the opening of the instrument panel can be kept constant.

Japanese Utility Model Publication No. 5-37592

  However, in the above prior art, when the convex portions on both sides of the lid are realized as resin pieces, the resin material is likely to creep, so if the deformation amount of the resin pieces increases with time, both the lid side portions and the opening of the instrument panel There is a problem that it is difficult to keep the gap between the two constant. On the other hand, when the convex portions on both sides of the lid are realized as projecting portions of the leaf springs, the leaf spring has a relatively narrow range of deflection in the elastic deformation region, so the gap between the lid sides and the instrument panel opening is relatively small. There has been a problem that sagging (permanent deformation) occurs due to the narrowing of the gap. Further, in the case of a leaf spring, there is a problem that it is difficult to set the operation load at the time of opening and closing the lid because the change in the load with respect to the change in the deflection amount is large.

  The present invention has been devised in view of such problems of the prior art, while stably generating an urging force necessary to prevent rattling or positioning between two members, An object is to provide an urging body that achieves high durability.

  A first invention made to solve the above problem is an urging body (1) interposed between a first member (2) and a second member (3), wherein the first member A base (11) attached to one member, a contact body (12) supported by the base in a swingable manner and elastically contacting the second member, and urging the contact body in the elastic contact direction And a torsion coil spring (13).

  As a second aspect of the present invention, the contact body may include a locking portion (43) that is locked to the base in a state where a predetermined twisting load is applied to the torsion coil spring.

  As a third invention, the base has an insertion portion (21) into which a part of the first member is inserted when the base is attached to the first member. A part (61) of the outer peripheral edge of the opening (21a) may be configured to extend in a direction away from the contact body.

  According to the first aspect of the invention, since the contact body is biased by the torsion coil spring, the biasing force necessary to prevent rattling or positioning between the two members is stably generated. There is an excellent effect of realizing high durability. According to the second aspect of the invention, since the initial torsion coil spring is held in a state where a predetermined torsional load is applied, the initial biasing force can be stably generated. The contact body can be stably elastically contacted with the second member without being affected by the size of the gap between the member and the second member. According to the third aspect of the present invention, since the tilting of the urging body in the direction away from the contact body is restricted by the extending portion provided at the outer peripheral edge of the insertion opening, the urging body is attached. Misalignment, separation from the first member, and the like can be prevented.

  Hereinafter, an urging body according to a first embodiment of the present invention will be described with reference to FIGS. The biasing body 1 is interposed between two members facing each other with a predetermined gap. In this embodiment, as shown in FIG. 1, a glove box 2 for an automobile and an instrument panel 3 (see FIG. 3)). The glove box 2 includes a resin box main body 4 and a resin lid 5 that is connected to a vehicle compartment side of the box main body 4 and fits into a mounting opening (not shown) of the instrument panel 3. ing. The glove box 2 is supported so as to be openable and closable with respect to the instrument panel 3 by a rotating shaft 6 provided on the side wall 7 of the lid 5. Although FIG. 1 shows a state in which the urging body 1 is attached to the right side wall 7 of the lid 5, the urging body 1 is similarly attached to the left side wall 8.

  As shown in FIG. 2, the biasing body 1 includes a resin base 11 fixed to the glove box 2, a resin contact body 12 that elastically contacts the instrument panel 3, and the contact body 12 in the elastic contact direction. And a torsion coil spring 13 made of metal that urges the spring.

  In the base 11, an attachment piece 22 (see FIGS. 3 and 5) that protrudes from the inside of the lid 5 is inserted into an opening 21 a provided in an insertion portion 21 that has a substantially cylindrical shape. As shown also in FIG. 5, the insertion preventing part 25 of the base 11 is formed in the insertion part 21 of the base 11 so that a part of the outer wall 24 is notched. The detachment prevention piece 25 is provided so as to be elastically deformable with the base end side as a fulcrum, and the detachment prevention protrusions 26 that project inward so as to face each other are latched on the side surface of the attachment piece 22. Locked in the groove 27. Thereby, the detachment of the base 11 attached to the lid 5 is prevented.

  As shown in FIG. 2, in the abutment body 12, the swing shaft 32 projecting outward from each of the connecting portions 31, 31 is a shaft hole 34 provided in both the connecting portions 33, 33 of the base 11. Are inserted respectively. Thereby, the contact body 12 is supported by the base 11 so as to be swingable. The torsion coil spring 13 is interposed between the base 11 and the contact body 12. More specifically, spring support shafts 35, 35 projecting inwardly from both coupling portions 31, 31 of the contact body 12 are inserted into the coil portion 13 a of the torsion coil spring 13. Further, two arm portions 13b and 13c are formed at both ends of the torsion coil spring 13, and these extend in substantially the same direction as the axis of the coil portion 13a, and are respectively formed inside the base 11 and the contact body 12. It is fixed. Thus, the torsion coil spring 13 biases the swing end side (that is, the side away from the swing shaft 32) of the base 11 and the contact body 12 around the swing shaft 32 in a direction to separate them from each other. .

  In the contact body 12, the elastic contact portion 42 that elastically contacts the inner surface 41 (see FIG. 4) of the instrument panel 3 has a swing regulating piece 43 that protrudes inwardly on the swing end side. The insertion portion 21 of the base 11 has a swing restriction block 45 that protrudes inwardly on the swing end side. The locking claw 46 provided at the tip of the swing restricting piece 43 is the swing restricting block 45 in a state where the torsion coil spring 13 is bent by a predetermined amount from the initial state (that is, a predetermined twist load is applied). It is latched in the latching hole 47 provided in the. The swing range of the contact body 12 is limited to a range in which the locking claw 46 can move within the locking hole 47.

  As shown in FIG. 5 (A), the urging body 1 has an elastic contact portion 42 elastically contacting the inner surface 41 of the instrument panel 3 when the lid 5 (glove box 2) is closed, as shown in FIG. 5 (B). When the lid 5 is opened, the elastic contact with the inner surface 41 of the instrument panel 3 is released. As shown in FIG. 3, the side wall 7 of the lid 5 is provided with an opening 7 a into which the elastic contact portion 42 is inserted. The elastic contact portion 42 protrudes more from the opening 7a on the swing end side than the swing shaft 32 side, so that the contact surface 42a is tilted to the base 11 side (that is, from the rear to the front). Toward the side wall 7 of the lid 5). In addition, the opening 7a is provided in a size that exposes only the contact surface 42a of the elastic contact portion 42, whereby the design of the side portion of the glove box 2 is favorably maintained.

  Further, as shown in FIG. 4, a contact protrusion 51 that protrudes inward is provided at a portion of the inner surface 41 of the instrument panel 3 where the elastic contact portion 42 contacts. By providing the contact protrusion 51, it is possible to avoid the elastic contact portion 42 from coming into contact with a portion other than the contact protrusion 51 on the inner surface 41 of the instrument panel 3. Is prevented.

  In the operation of the urging body 1 shown in FIG. 5, the bending amount of the torsion coil spring 13 is set to 0.5 (when the lid 5 is opened) to 2.5 (when the lid 5 is closed) mm. That is, in the initial state when the lid 5 is opened, the locking claw 46 is locked in the locking hole 47 in a state where the torsion coil spring 13 is bent by 0.5 mm from the initial state. As shown, the initial load (biasing force) of the torsion coil spring 13 is stably secured. Therefore, the gap between the instrument panel 3 and the glove box 2 is larger than the design value due to variations in dimensional accuracy, mounting accuracy, etc. (that is, the amount of deflection of the torsion coil spring 13 is smaller than the design value). Even in this case, the contact body 12 can be brought into elastic contact with the instrument panel 3 stably.

  Further, as shown in FIG. 6, the torsion coil spring 13 has a smaller change in load with respect to a change in the amount of deflection (amount of deformation due to a torsional load) than the leaf spring. Therefore, even if the gap between the instrument panel 3 and the glove box 2 changes to some extent, there is an advantage that the operation load necessary for opening and closing the glove box 2 is stabilized and the operability for the user is improved. Further, since the torsion coil spring 13 can be set so as to generate a large load with a small amount of deflection (for example, 1 mm) compared to the leaf spring, the biasing body 1 can be reduced in size, and the instrument panel 3 and the glove box 2 The degree of freedom in design can be improved. Further, the use of the torsion coil spring 13 has an advantage that the length of the biasing body 1 in the width direction (the axial direction of the coil portion 13a) can be reduced. Furthermore, since the torsion coil spring 13 can be used without causing a large load change with respect to the amount of bending, the torsion coil spring 13 has higher durability than the leaf spring and is stable without causing sag or the like even for a long period of use. Can be used.

  As described above, rattling and vibration between the glove box 2 and the instrument panel 3 are suppressed by the biasing body 1 interposed between the glove box 2 and the instrument panel 3. Further, the gap between the glove box 2 and the instrument panel 3 is kept constant, and an effect of positioning (centering) the glove box 2 with respect to the mounting opening of the instrument panel 3 is obtained.

  Next, an urging body according to a second embodiment of the present invention will be described with reference to FIGS. Constituent elements similar to those in the first embodiment described above are denoted by the same reference numerals, and redundant descriptions are omitted.

  In the biasing body 1 according to the second embodiment, the insertion portion 21 of the base 11 has a tilt prevention piece 61 that extends in a direction in which a part of the outer peripheral edge of the opening 21 a is separated from the contact body 12. Yes. As shown in FIG. 8, the outer wall 24 on which the detachment prevention piece 25 is formed has a substantially L-shaped edge. Further, the swing restricting block 45 is attached to the edge of the opening 21 a and is located further on the swing end side than the front end position of the outer wall 24. The tilt prevention piece 61 comes into contact with the upper surface of the tilt prevention block 62 formed integrally with the mounting piece 22 of the lid 5. Thereby, when the contact body 12 contacts the instrument panel 3, the tilting of the biasing body 1 in the direction away from the contact body 12 is restricted. The detachment from 5 can be prevented. In addition, the influence of the reaction force generated on the tilt prevention piece 61 is eliminated by the detachment prevention protrusion 26 being engaged with the engagement groove 27.

  Next, an urging body according to a third embodiment of the present invention will be described with reference to FIGS. 9 and 10. Constituent elements similar to those in the first and second embodiments described above are denoted by the same reference numerals, and redundant descriptions are omitted.

  In the urging body 1 according to the third embodiment, a convex portion 71 is formed at the center of the contact surface 42a of the elastic contact portion 42. As shown in FIG. 10, only the convex portion 71 is exposed from the opening 7 a of the side wall 7 of the lid 5. With such a configuration, the size of the opening 7a (exposed portion of the biasing body 1) can be reduced, and the design of the side portion of the glove box 2 is improved. Further, there is an advantage that the inside of the lid 5 cannot be seen from the gap between the opening 7a and the peripheral edge of the convex portion 71.

  Although the present invention has been described in detail based on specific embodiments, the above embodiments are merely examples, and the present invention is not limited to these embodiments. For example, the urging body according to the present invention is not limited to the glove box and the instrument panel, and can be interposed between any two members. Moreover, in the above-mentioned embodiment, the structure which provides an urging body in the instrument panel side, and contact | abuts a contact body to a glove box is also possible.
