Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for mounting two members such as casing components in a car audio or the like.
[0002]
[Prior art]
For example, in a car audio housing or the like, another part is often attached to a base material such as a molded resin panel. When attaching another part in this way, as shown in FIG. 6, there is a method in which the part 2 is screwed to the base material 1 with a screw 3 as shown in FIG. 6. As another attachment method, as shown in FIG. 7, a hook 4 is formed on a portion of the substrate 1 to which the part 2 is attached, and the hook 4 is also provided with a hinge structure. Some parts are attached by engaging the part 2 with the hook 4.
[0003]
[Problems to be solved by the invention]
By the way, the above-described mounting method has the following problems. That is, since the attachment method shown in FIG. 6 requires a screwing operation, it takes time and cost for the screwing.
[0004]
In addition, as shown in FIG. 7, when the hook 4 is provided with a hinge structure, the hook 4 rotates around the root fulcrum. For this reason, a space for enabling the hook 4 to rotate is required. In FIG. 7, the α portion is the space portion. Recently, however, there are many products whose space efficiency has been improved due to complexity, miniaturization, and the like, and there is a case where space for the hinge structure cannot be taken for such products. Therefore, the hook 4 having the hinge structure is not suitable for such a space efficient product. In addition, since the hinge structure rotates around a fulcrum, the structure is weaker than other parts and has a drawback that it can be easily broken.
[0005]
The present invention has been made based on the above circumstances, and an object of the present invention is to provide an attachment structure that can be easily attached and is excellent in space efficiency and strength.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention provides a first member having a space sandwiched between two opposing wall surfaces, and a second member that is partially inserted into the space and engages with the first member . And a hook extending in the direction of closing the space is formed inside one of the two wall surfaces, and the second member has a hook. Projecting in the extending direction of the first member , being bent while being bent with respect to the hook at the time of insertion, and inserted into the space of the first member together with the bent portion, and protruding in the inserting direction of the first member so that provided a restricting portion having a disengagement preventing function from the member.
[0007]
For this reason, it is possible to easily fit the second member into the hook formed on the first member by bending the bending portion formed on the second member. In addition, if the bent portion is fitted into the hook, the bent portion and the restricting portion prevent the bent portion from being detached from the hook, so that the second member can be supported by the hook without providing a hinge structure on the hook. It becomes. Further, since it is not necessary to provide the hinge structure on the hook, it is possible to prevent problems such as strength reduction caused by providing the hinge structure, and to improve the strength of the hook. Further, since it is not necessary to provide a hinge structure, a space for the hook to rotate around the fulcrum is unnecessary, which contributes to an improvement in product space efficiency.
[0008]
According to another invention, in the above-described invention, the first member includes a projecting flange projecting to the side engaged with the second member, the wall surface of the projecting flange is in contact with the restriction portion, and the two wall surfaces It has a two-part mounting structure on the wall surface on the side where no hook is formed.
[0009]
For this reason, the bent portion of the second member engages with the hook while being elastically deformed before the second member hits the contact support portion. Accordingly, the second member can be supported by the hook and the projecting flange formed on the first member, and the second member can be prevented from being detached from the first member. Further, since it is not necessary to provide the hinge structure on the hook, it is possible to prevent problems such as strength reduction caused by providing the hinge structure, and to improve the strength of the hook. Further, since it is not necessary to provide a hinge structure, a space for the hook to rotate around the fulcrum is unnecessary, which contributes to an improvement in product space efficiency.
[0010]
Furthermore, in addition to each of the above-described inventions, another invention is such that the bending portion is formed at the end of the second member. For this reason, it becomes easy to engage a 2nd member with a hook, and the workability | operativity in the case of attaching the 1st member and 2nd member which perform attachment operation | work improves. As a result, the productivity of mounting is improved and the cost can be reduced.
[0011]
Further, in another invention, in addition to the above-described invention, the bending portion is formed to be warped. For this reason, when this bending part is engaged with the hook formed in the 2nd member, the 2nd member is elastically supported with respect to the hook. Thereby, stable elastic support is realized.
[0012]
In addition to the above-described inventions, the second member may further include a second member extending along a contact support portion that is an end portion of the wall surface on the side where the hooks of the two wall surfaces are not formed. A restricting member that restricts movement of the second member is formed. For this reason, it can prevent that a 1st member and a 2nd member slide relatively to a horizontal direction by a control member, and can bend | insert a bending part stably to a hook. At the same time, since the two members can be prevented from moving relative to each other by the restricting member, the engaged state can be stably maintained when the bent portion is engaged with the hook.
[0013]
Further, in another invention in addition to the inventions described above, than contact supporting portion a hook provided in the direction opposite to the insertion direction, the distance between the surface and the abutment support portion on the side of the insertion direction of the hook, The two-part mounting structure is slightly smaller than the thickness of the flexure. For this reason, even if it does not make the bending part warp in advance, the urging force from the bending part acts on the hook.
[0014]
Further, according to another invention, in addition to each of the above-described inventions, an insertion hole is formed in the first member, and a communication hole communicating with the insertion hole is formed in the second member. That's what it meant. For this reason, when the second member is engaged with the hook and elastically supported, the insertion hole and the communication hole communicate with each other.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. First, the first embodiment will be described with reference to FIGS.
[0016]
A case 10 to which the mounting structure of the present invention shown in FIG. 1 is applied shows a case where a CD guide member 12 as a second member is attached to a front panel 11 of a car audio as a first member. In this embodiment, the front panel 11 is formed of a material that can be bent and deformed by a predetermined amount, such as resin. The front panel 11 is formed with a CD insertion slot 13 as an insertion hole at a portion into which a CD is inserted. The CD insertion port 13 is formed in a long hole shape corresponding to the CD.
[0017]
Further, as shown in FIGS. 1 and 2, the CD insertion slot 13 is formed with a protruding flange 14 that protrudes toward the inner surface side of the front panel 11. The protruding flange 14 is formed over the entire circumferential direction of the long hole shape of the CD insertion slot 13, and protrudes vertically from the opening side of the CD insertion slot 13 toward the inside of the housing 10. It is provided in a taper shape so that the interval of 14 becomes narrow. Thereby, when the CD is inserted from the outside, the insertion operation is facilitated.
[0018]
Of the protruding flange 14, a pair of opposing portions provided in parallel to the axial direction of the long hole shape provided to face each other is formed so that the width becomes the largest in the central portion in the longitudinal direction. ing. That is, since the CD has a circular shape, when the CD is inserted into the CD insertion slot 13, the CD is always inserted from the center of the CD insertion slot 13. For this reason, in order to make it easy to insert a CD, it is formed wider toward the center of the CD insertion slot 13.
[0019]
Here, among the projecting ends formed to project inwardly of the projecting flange 14, an inner projecting end portion (hereinafter referred to as a contact support portion 14a) positioned above and a position positioned below. The inward protruding end portion (hereinafter referred to as a contact support portion 14b) is provided so that the line connecting these tips is substantially parallel to the plane of the front surface 11a of the front panel 11. It has been. Accordingly, when the CD guide member 12 is attached here, the CD guide member 12 is provided so as to be parallel to the plane of the front surface 11 a of the front panel 11.
[0020]
A hook 15 extends along the longitudinal direction of the CD insertion slot 13 in the vicinity of a portion where the straight line connecting the tips of the contact support portion 14a and the contact support portion 14b collides with the upper wall in FIG. It is provided at a plurality of places, in this embodiment, at three places. The hook 15 engages the CD guide member 12 while receiving an urging force from a bending portion 17 described later of the CD guide member 12. Thereby, the CD guide member 12 is provided to be fitted. Note that the hook 15 is a small protrusion whose length in the width direction is approximately the same as the thickness in order to fit the CD guide member 12 well.
[0021]
Further, a pin (not shown) for fitting the CD guide member 12 together with the hook 15 may be formed on the projecting flange 14 provided below. When a pin is formed, a pin hole through which the pin is inserted is also formed in the CD guide member 12.
[0022]
The CD guide member 12 attached to the front panel 11 a has a size and shape corresponding to the CD insertion slot 13. In this case, the portion of the CD guide member 12 that contacts the contact support portions 14 a and 14 b of the CD insertion opening 13 serves as the contact portion 16.
[0023]
Of the abutment portion 16, the end portion on the hook 15 side is a bending portion 17 provided so as to be warped toward the insertion guide portion 19 described later immediately before the engagement with the hook 15. The bending portion 17 is provided so as to be elastically deformed when fitted into the hook 15, and the CD guide member 12 is engaged with the hook 15 or the like by this elastic deformation.
[0024]
A communication hole 18 is formed in the contact portion 16 so that the CD can be inserted through the CD insertion port 13. The opening shape of the communication hole 18 is formed to be approximately the same size as the inner side shape of the CD insertion port 13.
[0025]
Further, an insertion guide portion 19 is erected from the communication hole 18 toward the rear end side of the front panel 11. The insertion guide portion 19 is also formed over the entire circumferential direction of the communication hole 18. Further, in the insertion guide portion 19, the contact portion 16 side of the communication hole 18 is formed to have the narrowest width W1, and the width W2 increases from the contact portion 16 side toward the rear end side of the front panel 11. Is formed.
[0026]
Here, between the bent portion 17 of the CD guide member 12 and the communication hole 18, one or a plurality of restricting portions 20 projecting to the front side of the front panel 11 are provided along the longitudinal direction of the CD insertion hole 13. In the embodiment, one is formed. The restricting portion 20 is in contact with the side surface of the projecting flange 14 and is provided with a tapered tapered surface 20a at its tip so that smooth CD insertion is possible. At the same time, it guides a stable fitting operation of the CD guide member 12, and once it is fitted, the fitted state is stably maintained.
[0027]
In the case 10 including the front panel 11 and the CD guide member 12 having the above-described configuration, when the CD guide member 12 is fitted, the CD guide member 12 is advanced toward the contact support portions 14a and 14b ( FIG. 2 (A)) is brought into contact (FIG. 2 (B)). Thereafter, the bending portion 17 is elastically deformed with respect to the hook 15 and is fitted. The elastic deformation of the bending portion 17 may be configured such that the bending portion 17 is slightly bent in advance toward the insertion guide portion 19 side.
[0028]
When the bent portion 17 is fitted into the hook 15, the bent portion 17 is deformed from the warped state as shown in FIG. In this case, the bending portion 17 is in a state of being fitted into the hook 15. In addition, since the bending part 17 bends like FIG.2 (B) in the middle of engaging, when it will be in this FIG.2 (C) state, the deformation | transformation will remain a little, and in such a case The bent portion 17 is in a state of applying a biasing force to the hook 15.
[0029]
In addition to this, the CD guide member 12 is stably fitted by the restriction portion 20, the contact portion 16 that is in contact with the contact support portions 14a and 14b, and the engagement and fitting of pins (not shown). Maintain and keep it from coming off.
[0030]
In the casing 10 including the front panel 11 and the CD guide member 12 having such a configuration, the bending portion 17 is fitted into the hook 15 while being elastically deformed with the contact portion 16 as a fulcrum in the vicinity of the communication hole 18. By this engagement and the engagement of the restricting portion 20, the abutting portion 16 abuts against the joint support portions 14a and 14b, and the CD guide member 12 can be supported by the hook 15 and the projecting flange 14. It is possible to prevent the CD guide member 12 from coming off. That is, it is possible to stably maintain the state in which the CD guide member 12 is fitted by the hook 15, the protruding flange 14, and the like.
[0031]
Further, when the bending portion 17 is bent in advance to the insertion guide portion 19 side, the contact support portions 14a and 14b abut on the contact portion 16 in the fitted state, and the bending portion 17 is elastically deformed and held. Therefore, the bending portion 17 exhibits an elastic force starting from the contact support portions 14a and 14b, and the CD guide member 12 can be reliably elastically supported.
[0032]
Further, since it is not necessary to provide the hinge structure on the hook 15, it is possible to prevent problems such as a decrease in strength caused by providing the hinge structure, and to improve the strength of the hook 15. Furthermore, since it is not necessary to provide a hinge structure, a space for the hook 15 to rotate with the root as a fulcrum is not necessary, which contributes to an improvement in product space efficiency.
[0033]
Further, since the bent portion 17 is formed at the end portion of the CD guide member 12, it can be easily sandwiched, and the CD guide member 12 can be easily fitted into the hook 15, thereby improving workability in the mounting operation. It becomes. As a result, the productivity of mounting is improved and the cost can be reduced.
[0034]
Further, the CD guide member 12 is restricted from moving along the contact support portions 14a and 14b to the back of the bent portion 17 of the CD guide member 12 or the side where the restricting portion 20 of the front panel 11 is fitted. If a restricting member (not shown) is formed, the restricting member can prevent the CD guide member 12 from sliding along the longitudinal direction. For this reason, since the bending part 17 can be stably fitted into the hook 15 and the movement can be prevented, when the bending part 17 is fitted into the hook 15, the fitted state can be stably maintained. Is possible.
[0035]
Next, a second embodiment of the present invention will be described.
[0036]
In the second embodiment, the front panel 11 has the same structure as that of the first embodiment, and only the CD guide member 12 is changed. For this reason, only the CD guide member 12 is shown in FIG. The same members and the same parts as those in the first embodiment will be described using the same reference numerals, and the description thereof will be omitted or simplified.
[0037]
The rear of CD guide member 12, as shown in FIG. 3 (A), a plurality of triangular partition walls 31 for high Mel the rigidity of the flexure 17, opposite to the bending portion 17 those the rigidity of contact section 16 and a plurality of square-shaped partition wall 32 for high Mel is provided. The height of the vertical wall 32 is about half that of the insertion guide portion 19. Since the vertical wall 31 is disposed in a positional relationship (see FIG. 3) in the vicinity of each hook 15 and prevents the CD guide member 12 from sliding in the longitudinal direction when it is assembled, It has become.
[0038]
On the other hand, on the front surface of the CD guide member 12, that is, on the abutting portion 16 side, a plurality of circles that are positioned when a single restricting portion 20 and a felt material (not shown) are pasted over the entire abutting portion 16 Columnar protrusions 33 are provided. Further, the CD guide member 12 has two through holes 34 into which positioning pins (not shown) provided in the front panel 11 enter, and two screws through which screws engaged with screw holes provided in the front panel 11 pass. A screw hole 35 is provided.
[0039]
In the second embodiment, the hooks 15 provided on the front panel 11 are configured at three locations so as to engage with the arrow H portion in FIG. At the time of this engagement, the flexure 17 has a predetermined rigidity. Therefore, at the time of engagement, as shown in FIG. 2, it is not incorporated from the direction perpendicular to the plane of the front surface 11a of the front panel 11. , obliquely from below, the first deflection section 17 is engaged with the inner side of the hook 15, then to fit by rotating the CD guide member 12 it clockwise.
[0040]
As mentioned above, although each embodiment of this invention was described, this invention can be variously deformed besides this. This will be described below. In each of the above-described embodiments, the front panel 11 is described as a first member, and the CD guide member 12 is described as a second member. However, the first member is not particularly limited, and the second member is not particularly limited, and the present invention can be applied to mounting structures in various members and apparatuses.
[0041]
In each of the above-described embodiments, the case where the CD guide member 12 is attached to the front panel 11 has been described with respect to the case where the hook 15 is provided in only one direction. However, as shown in FIG. The present invention may be applied to the case where the hook 15 is disposed so as to face the base material and the second member such as the CD guide member 12 is sandwiched by the hook 15 located at the opposed position.
[0042]
In the configuration of FIG. 4 as well, when a second member such as the CD guide member 12 is engaged with the front panel 11 of the first member, the end portion of the second member is a bent portion 17 that warps. Disengagement is prevented by fitting. In addition, when the urging | biasing force can be produced in the hook 15 by the curvature of the bending part 17, it also becomes possible to implement | achieve a favorable elastic support state. In such a configuration, since the only fitting the hook 15, it is possible to realize easily elastically supported by straightforward single work. In addition, it is good also as the state which bent the bending part 17 previously. In this case, the elastic support force at the time of engagement becomes large and the support force is stabilized.
[0043]
In addition, as shown in FIG. 5, if the distance M1 between the hook 15 and the contact support portions 14a and 14b is slightly smaller than the thickness M2 of the bending portion 17, the bending portion 17 is not warped in advance. However, the urging force from the bending portion 17 acts on the hook 15. By adopting such a structure or by installing the restricting portion 20 slightly below the state shown in FIGS. 2 and 5, a strong urging force acts between the restricting portion 20 and the protruding flange 14, and the CD guide member 12 Can be held firmly.
[0044]
In each of the above-described embodiments, the front panel 11 and the CD guide member 12 are both resin members having elasticity. However, one of the members 11 and 12 is a metal material and the other is elastic. You may comprise as a resin material to have. When the CD guide member 12 is made of a metal material, the projecting flange 14 and the hook 15 are bent without bending the bending portion 17.
[0045]
【The invention's effect】
According to the present invention, the second member can be easily engaged with the hook formed on the first member by bending the bent portion formed on the second member. Moreover, since a control part and a bending part are pinched | interposed by the 1st member, engagement of both members is not released. Furthermore, if the bent portion is engaged with the hook and the restricting portion is engaged with the projecting flange, both members will not come off, thereby supporting the second member with the hook without providing a hinge structure on the hook. Is possible.
[0046]
Further, since it is not necessary to provide the hinge structure on the hook, it is possible to prevent problems such as strength reduction caused by providing the hinge structure, and to improve the strength of the hook. Further, since it is not necessary to provide a hinge structure, a space for the hook to rotate around the fulcrum is unnecessary, which contributes to an improvement in product space efficiency.
