Description

  The present invention relates to a mounting part fixing structure configured to fix a locking claw provided on a mounting part to a mounting hole of a vehicle body panel or the like. In addition to fixing the trim member, it can also be applied to fixing an appropriate mounting part to a vehicle body panel or the like.

Conventionally, various methods have been proposed for attaching a trim member, which is a vehicle interior material such as an automobile, to a vehicle body panel. Usually, in order to attach a trim member or the like as an attachment part to the vehicle body panel, a flexible locking claw having a retaining portion on the attachment part side is inserted into the attachment hole of the vehicle body panel and fixed. If the locking claw is relatively rigid, the locking claw is securely fixed and the retaining portion does not fall out after locking, but the resistance at the time of insertion is large and the working efficiency is lowered. In view of this, in the locking structure, a structure in which insertion resistance to the attachment member to the attachment member is eliminated to improve workability has been proposed (for example, see Patent Document 1 below).
Japanese Patent Laid-Open No. 7-133819 (refer to claim 1 and FIG. 1)

  The locking structure disclosed in Patent Document 1 will be described with reference to FIG. On the lower surface of the short sides 112C and 112D of the frame portion 112 of the locking knob coupler 110, claws 116 and 122 and claws 118 and 120 arranged on the same diagonal line are formed. The heights of the engaging portions 116A and 122A of the claws 116 and 122 are set lower than the heights of the engaging portions 118A and 120A of the claws 118 and 120, and the height of the engaging portion 116A and the height of the engaging portion 122A. Are the same, and the height of the engaging portion 118A and the height of the engaging portion 120A are the same. A locking hole 132 is formed in the door trim 130, and when the locking knob collar 110 is attached to the door trim 130, the locking knob collar 110 is attached to a half portion in the width direction of both side surfaces 132 A and 132 B in the longitudinal direction. Recesses 134 and 136 for preventing the claws 118 and 120 from interfering with the door trim 130 are formed.

  With such a configuration, in the locking structure in which the mounting member having a plurality of claws having at least two types of heights can be attached to the locking portions of the mounted members having different thicknesses by the locking of the claws, Since a recess that does not interfere with the movement trajectory when inserting a nail that is not used for locking is formed on the side surface of the locking portion, the insertion resistance of the mounting member to the mounted member can be reduced, and workability is improved. It became possible. However, in such a conventional device, although the insertion resistance of the mounting member to the mounted member can be reduced, the ease of insertion still depends on the flexibility of the nail. Therefore, the ease of insertion inevitably caused easy removal.

  Therefore, the present invention solves such a problem of the conventional locking structure, and even if a relatively flexible locking claw is used, it does not fall out into a mess after locking and fixing, and it is easy to conflict with insertion. It is an object of the present invention to provide a mounting part fixing structure that enables both fixed fixing and reliable fixing.

  For this reason, the present invention provides a mounting part fixing structure configured to fix a locking claw provided on a mounting part to a mounting hole of a vehicle body panel or the like. And an interval holding member capable of entering between the pair of locking claws is provided swingably on the locking claws or mounting parts. Further, the present invention is characterized in that the spacing member is provided in a single hinge form. Further, the present invention is characterized in that the spacing member is provided on each locking claw in a double-hinged manner. Further, the present invention is characterized in that the spacing member is provided on each locking claw in a double hinge form, and the opposing surfaces of the spacing member are connected by a thin portion. In the invention, it is preferable that the spacing member is formed of a box-like body having an inclined side. Further, the present invention is characterized in that a stopper capable of maintaining the spacing member in a state substantially orthogonal to the locking claw is provided, and these are means for solving the problems.

  According to the present invention, in the mounting part fixing structure configured to fix the locking claws provided in the mounting part to the mounting hole of the vehicle body panel or the like, the pair of locking claws having a retaining portion and the interval can be changed are attached to the mounting part. In addition, a pair of interval holding members that can enter between the pair of locking claws are swingably provided on the locking claws or mounting parts, so that a pair of relatively flexible and flexible intervals can be changed. While holding the pawl easily into the mounting hole of the vehicle body panel, etc., the work efficiency can be improved, the gap is kept against the edge of the mounting hole and forcibly entering between the pair of pawls The action of the member reliably prevents the retaining portion of the locking claw from falling out of the mounting hole.

  Further, when the spacing member is provided in the form of a single hinge, the spacing between the pair of locking claws is maintained by the swinging of the spacing member of the single hinge type having a relatively simple structure. Furthermore, when the interval holding member is provided on each locking claw in the form of both hinges, the interval holding member adopts the both hinge type, whereby the swing stroke of each interval holding member can be made relatively small, With respect to the degree of insertion of the attachment component such as the trim member into the locking hole, it is possible to advance the interval of holding the claw, that is, the locking timing.

  Furthermore, when the spacing member is provided on each locking claw in the form of both hinges and the opposing surfaces of the spacing member are connected by a thin portion, the swing strokes of the spacing members are compared. The interval holding time of the locking claws, that is, the locking time can be advanced, and the swing angle of each interval holding member of both hinge types can be synchronized to equally hold the distance between the pair of locking claws. . Moreover, when the said space | interval holding member is comprised from the box-shaped body which has an inclined side, a space | interval holding | maintenance of a pair of latching claw can be reliably performed with the box-shaped body of a comparatively strong structure. In addition, due to the presence of the inclined side, the interval can be gradually maintained although it is forcibly not an abrupt interval maintaining lock.

  Furthermore, when the stopper that can maintain the interval holding member in a state substantially orthogonal to the locking claw is provided, the interval holding member is securely fixed between the edge of the mounting hole of the vehicle body panel and the stopper, The interval holding member is maintained in a good orthogonal relationship with the pair of locking claws, and the interval holding function can be sufficiently exhibited.

FIG. 4 shows a third embodiment of the mounting part fixing structure of the present invention, FIG. 4 (A) is a perspective view, FIG. 4 (B) is an enlarged view of the main part, and FIG. 5 is the present invention. FIG. 5 (A) is a perspective view, FIG. 5 (B) is a plan view of an essential part, and FIG. 6 is a fifth embodiment of the mounting part fixing structure of the present invention. 6A is a perspective view, and FIG. 6B is a plan view of the main part.

  As shown in FIG. 1, the basic structure of the present invention is an installation in which locking claws 5 and 6 provided on a trim member 1 as an attachment part are inserted and fixed in an attachment hole 3 of a vehicle body panel 2 or the like. In the component fixing structure, the trim member 1 is provided with a pair of locking claws 5, 6 having the retaining portions 5 </ b> B, 6 </ b> B that are freely changeable, and a spacing member 7 that can enter between the pair of locking claws 5, 6. Is provided on the locking claws 5 and 6 or the trim member 1 so as to be swingable.

  Examples will be described in detail below. FIG. 2 is a side view of the rear part of the vehicle body and shows the vicinity of the quarter window 9. As shown in FIG. 1A, which is an AA cross-sectional view of the upper part of the quarter window 9, as shown in FIG. Then, when attaching the trim member 1 which is an interior material to the attachment hole 3 of the roof panel inner), the locking claw 4 is provided on the trim member 1. As shown in FIG. 1C, the locking claws 4 are composed of a pair of relatively soft and flexible locking claws 5 and 6 made of the same material as the trim member 1 made of plastic or the like. The pair of locking claws 5 and 6 are arranged upright in parallel with a predetermined interval, and their heads are bent and can be deformed in proximity.

  Inclined surfaces 5A and 6A are formed at the heads of the locking claws 5 and 6, respectively, and retaining portions 5B and 6B are formed at the lower portions thereof. Rear inclined surfaces 5C and 6C are formed at the rear portions of the respective locking claws 5 and 6 (the forward side of the arrow in FIG. 1A is the front portion), and the alignment operation of the locking claws 5 and 6 to the mounting hole 3 is performed. Do. That is, when the locking claws 5, 6 are being inserted at appropriate positions in the front-rear direction of the mounting hole 3 (the direction of the arrow in FIG. 1A), the rear inclined surfaces 5 C, 6 C are the rear end of the mounting hole 3. Since it contacts the edge, the locking claws 5 and 6 can be guided forward.

  In the present embodiment, a one-hinged interval holding member 7 is integrally formed on the front surface of the second locking claw 6. The spacing member 7 swings between the pair of locking claws 5 and 6 and enters the state of being orthogonal to these, and properly holds the spacing between them (dotted line in FIG. 1B). ). And the stopper 8 is formed inside the 1st latching claw 5 so that the orthogonal | vertical state of the space | interval holding member 7 can be maintained. The hinge part to the 2nd latching claw 6 of the space | interval holding member 7 is comprised by the thin part. Preferably, a thin portion is formed on the distal end side when the interval holding member 7 enters between the locking claws 5 and 6 and the interval is held. This is because the entire thickness of the spacing member 7 can contribute to spacing.

  Since it comprised in this way, as shown to FIG. 1 (B), when the latching claws 5 and 6 provided in the trim member 1 are inserted in the latching hole 3 (one-dot chain line) of the vehicle body panel 1, The rear inclined surfaces 5C and 6C of the locking claws 5 and 6 are brought into contact with the rear edge 3R of the locking hole 3 and move upward while guiding the locking claws 5 and 6 forward. When the locking claws 5, 6 move further forward and upward, the spacing member 7 comes into contact with the front edge 3 </ b> F of the mounting hole 3, and forcibly swings as shown by the dotted line. , Enter between 6. At this time, the retaining portions 5 </ b> B and 6 </ b> B have already reached the top of the mounting hole 3 at the heads of the respective locking claws 5 and 6. Finally, the interval holding member 7 is restricted from swinging between the front edge 3F of the mounting hole 3 and the stopper 8, and holds the interval between the locking claws 5 and 6 in an orthogonal state. Even the locking claws 5 and 6 made of a material no longer fall out of the locking hole 3.

  FIG. 3 is a perspective view showing a second embodiment of the mounting component fixing structure of the present invention. The thing of a present Example is the example in which the space | interval holding member 7 was provided in each latching claw 5 and 6 in the form of both hinges. Spacing members 7A and 7B are hinged to the front surfaces of the respective locking claws 5 and 6 by thin portions as in the first embodiment. Reference numeral 8 in the drawing is a stopper that is installed upright from the trim member 1 that is a mounting part. Thus, the trowels of the respective spacing members 7A and 7B can be made relatively small, and the spacing time of the locking claws 5, 6 relative to the degree of insertion of the mounting parts such as the trim member 1 into the locking hole 3, that is, the locking time. Can be accelerated.

  FIG. 4 shows a third embodiment of the mounting part fixing structure according to the present invention. As shown in FIG. 4A, the distance holding member 7A is the same as that of the second embodiment as shown in FIG. , 7B are provided on the respective locking claws 5, 6 in the form of both hinges, but in this embodiment, the opposing surfaces of these spacing members 7A, 7B are connected by a thin portion 7C. . With such a configuration, the swing strokes of the spacing members 7A and 7B can be made relatively small, the spacing time of the locking claws 5 and 6, that is, the locking time can be advanced, and the connection by the thin portion 7C can be achieved. The portions can synchronize the swinging angles of the space holding members 7A and 7B of both hinge types, and the space between the pair of locking claws 5 and 6 can be evenly held.

  Further, as shown in FIG. 4B, when the thin portion 7C is formed at the rear portion in the direction in which the trim 1 is inserted, the opposing surfaces of the spacing members 7A and 7B on the front side of the thick portion 7C are respectively provided. By forming the protrusions 7D and 7E, the rearward swinging of the spacing members 7A and 7B is restricted and has a stopper function, so that it is not necessary to provide a separate special stopper.

  FIG. 5 shows a fourth embodiment of the mounting part fixing structure of the present invention. As shown in FIG. 5 (A), an example in which the spacing member 7 is composed of a box-shaped body having inclined sides 7F and 7F. It is. In the illustrated example, it has a triangular shape in a side view, and its lower end is hinged to the trim member 1 so as to be swingable. Although it is a horizontal hinge form, like the above-mentioned Example, it may be hinge-coupled by the vertical axis | shaft to one front surface of the latching claws 5 and 6 (In this case, one surface of a triangle gradually hold | maintains a space | interval. It goes without saying. As shown in FIG. 5B, the upper surface of the box-shaped spacing member 7 is inclined surfaces 7E and 7E which are narrow on the side of the locking claws 5 and 6. The rear surface is connected to the hinge portion while maintaining its narrow width. As the trim member 1 advances, the spacing member 7 enters between the locking claws 5 and 6 from the dotted line position 7 ′ and reaches the solid line position 7. With such a configuration, the pair of locking claws 5 and 6 can be reliably held by the box-shaped body having a relatively strong structure. In addition, due to the presence of the inclined side 7F, it is not a sudden interval holding lock, but the interval holding can be performed gradually but forcedly, and the impact load on the front surfaces of the locking claws 5 and 6 by the interval holding member 7 is reduced. be able to.

  FIG. 6 shows a fifth embodiment of the mounting part fixing structure according to the present invention, which is an example in which the interval holding function and the stopper function are improved by devising the shape of the interval holding member. . As shown in FIG. 6 (A), the planar shape of the spacing member 7 of the present embodiment is configured in a substantially triangular shape. The thin hinge portion is set to the front side when the interval holding member 7 is orthogonally locked (when holding the interval), and the bottom side of the triangle is brought into contact with the inner side of the second locking claw 6 when orthogonally locking. With this configuration, as shown in FIG. 6B, when orthogonally locked, the triangular base 7G side of the spacing member 7 abuts on the inner side of the second locking claw 6, and the spacing member 7 Further restraining the swinging to the rear side more reliably, it can disperse sufficiently on the wide base 7G side of the triangle against the force that the locking claws 5 and 6 try to approach, Exhibits a high spacing function.
