Utility Model Registration No. 2500328

  By the way, in order to simplify the structure, a structure in which the lid is attached to the interior panel only by the engagement of the locking claw and the locking portion without using the hinge is conceivable. In such a structure, for example, a driver or the like If the lid unintentionally touches the lid and removes the locking claw from the locking portion, it is expected that the lid will fall off the interior panel and be lost.

  The present invention has been made in view of the above points, and while adopting a structure in which the lid is attached to the interior panel only by the engagement between the locking claw and the locking portion, the locking claw is removed from the locking portion. The purpose is to prevent the lid from falling off the interior panel in case of accidental detachment.

In order to achieve the above object, according to the present invention, a plurality of support pieces each having a locking claw project from a back surface of a lid for closing an opening provided in an interior panel of a vehicle, while the locking claw is elastic. A lid mounting structure in which a plurality of locking holes for maintaining a closed state of the lid by engagement are provided in the interior panel, wherein at least one of the plurality of support pieces (3) is provided. On the tip side, an extension that is longer than the other support pieces is integrally formed to be continuous in a straight line, and this extension has the same shape and the same orientation as the locking pawl of the support piece. While the claw is formed, the locking part that can be engaged with the locking claw of the support piece with the extension part is used as a locking hole, and when the lid is attached to the interior panel, the auxiliary claw of the extension part is first attached. After passing through the locking holes, the locking claws of all the plurality of support pieces are When the latching claw of each of the plurality of support pieces is disengaged from the latching part and the latching hole corresponding to each of the latching part and the latching hole corresponding to each, the auxiliary The claw is engaged with the locking hole to prevent the lid from dropping off .

The present invention, in addition to the first feature, the locking force against the locking holes of the secondary pawl, larger than the locking force against the locking holes of the locking claw of the supporting piece with the extension section This is the second feature.

  The interior panel corresponds to an instrument panel P in an embodiment of the present invention to be described later, and the support piece, the locking claw and the locking portion are the side support piece 3, the side locking claw 6 and It corresponds to each of the locking holes 19.

According to the first feature of the present invention, at least one of the plurality of support pieces is integrally provided at the front end side of the support piece so as to be linearly continuous with an extension that is longer than the other support pieces. And an auxiliary claw having the same shape and orientation as the locking claw of the support piece, and the locking portion that can be engaged with the locking claw of the support piece with the extension. When attaching the lid to the interior panel, after the auxiliary claw of the extension part first passes through the corresponding locking hole, the locking claw of all the support pieces corresponds to the corresponding locking part. The lid can be attached to the interior panel by engaging with the locking hole. In addition, when the latching claws of all these support pieces are separated from the corresponding latching holes, the auxiliary claws can engage with the corresponding latching holes to prevent the lid from falling off. For example, even if the driver or the like unintentionally touches the lid and removes all the locking claws from the corresponding locking portions and the locking holes , the auxiliary claw of the extension portion is caught in the corresponding engaging holes, proof technique from falling out of the interior panel, with the loss of the lid can be prevented, the lid can be immediately recognized by the driver or the like that off.

Moreover, an extension, as well as formed to be continuous in a straight line on the distal end side of the support piece, the auxiliary pawl of the extension portion, the locking pawl of the same shape of the support piece, by forming the same direction, the extension While avoiding that the part is limited by the space in the opening, it is possible to simplify the mold for forming the support piece with the extension and contribute to the reduction of the manufacturing cost.

According to a second aspect of the present invention, that the locking force to the locking holes of the secondary pawl, was set greater than the locking force against the locking holes of the locking claw of the supporting piece with the extension section Therefore, it is possible to more effectively prevent the lid from falling off the interior panel.

  First, in FIG.1 and FIG.2, the code | symbol P shows the synthetic resin instrument panel of a motor vehicle. The vertical wall portion Pa of the instrument panel P is provided with a steering column through hole 1 and a substantially rectangular opening 2 adjacent to the right side thereof, and facing the opening 2, for example, a fuse box (Not shown) is attached to the back surface of the instrument panel P. And the lid L which closes the said opening part 2 is attached to the instrument panel P with the following lid attachment structures based on this invention.

  As shown in FIGS. 1, 3 and 4, the lid L is made of synthetic resin and has a substantially square shape when viewed from the front, and a plurality of side portions are supported on the back surface along the left and right side edges. The pieces 3 and a plurality of upper support pieces 4 are integrally projected along the upper edge.

In FIG. 3, three side support pieces 3 on the right side are vertically arranged in the illustrated example. Each side support piece 3 is formed in a plate shape and protrudes in a substantially horizontal direction from the back surface of the lid L with its plate surface oriented in the vertical direction. At this time, the side support piece 3 spreads in the horizontal direction. A pair of upper and lower reinforcing ribs 5 are integrally formed. The side support pieces 3 are integrally formed with side locking claws 6 between the upper and lower reinforcing ribs 5. The side locking claw 6, 2, 3, as shown in FIG. 6, is integrally connected to the side-wall supporting member 3 at one end portion of the front end side of the side-wall supporting member 3 as base end 6 a In addition, a U-shaped slit 7 is provided between the side support piece 3 and the side locking claw 6 so as to separate other portions from the side support piece 3. In this way, the side locking claws 6 are given elasticity that can be elastically deformed in the left-right direction. On one side of the free end of the side latching claw 6, that is, the end on the lid L side, a mountain-shaped protrusion 8 that undulates along the front and back direction of the lid L is formed integrally. The slope on the base end 6a side is a gentle slope 8a with a gentle slope, and the slope on the opposite side is a steep slope 8b with a steep slope.

As shown in FIGS. 2, 4, and 7, in particular, an extension portion 10 that is longer than the other upper and lower side support pieces 3 is linear at the distal end side of the intermediate side support piece 3. The extension portion 10 is integrally formed with an auxiliary claw 11 having the same shape and orientation as the side locking claw 6 of the side support piece 3. Accordingly, the auxiliary claw 11 is also integrally connected to the extension portion 10 with the one end portion on the distal end side of the side support piece 3 as the base end portion 11a, and the other portion is separated from the extension portion 10 so as to be separated from the extension portion 10. A U-shaped slit 12 is provided between 10 and the auxiliary claw 11. Thus, the auxiliary claw 11 is also provided with elasticity that can be elastically deformed in the left-right direction. On one side surface of the free end portion of the auxiliary claw 11, a mountain-shaped protrusion 13 that undulates along the front and back direction of the lid L is integrally formed, and this protrusion 13 also has a gentle slope 13a and a steep slope 13b.

  In FIG. 3, two side support pieces 3 having the left side locking claws 6 are arranged vertically in the illustrated example. Since these side support pieces 3 have a symmetrical structure with the two upper and lower side support pieces 3 on the right side, the left side support piece 3 corresponds to the right side support piece 3 in the figure. The same reference numerals are assigned to the parts to be repeated, and the duplicate description is omitted.

  3 to 5, three upper support pieces 4 are arranged in the left-right direction in the illustrated example. Each upper support piece 4 is formed in a plate shape and protrudes in a substantially horizontal direction from the back surface of the lid L with its plate surface oriented in the horizontal direction, and at that time, between the upper support piece 4 and the back surface of the lid L. The left and right pair of reinforcing ribs 14 are integrally formed. An upper locking claw 15 is integrally formed on the upper support piece 4 between the reinforcing ribs 14. As shown in FIG. 5, the upper locking claw 15 is integrally connected to the upper support piece 4 with one end portion on the distal end side of the upper support piece 4 as a base end portion 15a, and the other portion is connected to the upper support piece. A U-shaped slit 16 is provided between the upper support piece 4 and the upper locking claw 15 so as to be separated from the upper support piece 4. Thus, the upper support piece 4 is given elasticity that can be elastically deformed in the vertical direction. On one side surface (the upper surface in the illustrated example) of the upper support piece 4 is integrally formed with a mountain-shaped protrusion 17 that undulates along the front and back direction of the lid L. The slope on the base end 15a side is a gentle slope 17a, and the slope on the opposite side is a steep slope 17b.

As shown in FIGS. 2 and 6 to 8, on the other hand, the instrument panel P allows the insertion of all the side support pieces 3 on the right side of the lid L (as viewed from the back side of the lid L), A plurality of (three in the illustrated example) locking holes 19 with which the side locking claws 6 included therein can be elastically engaged, and all of the left side of the lid L (as viewed from the back side of the lid L) together to allow insertion of the support piece 3, the locking hole 19 a plurality of side locking claws 6 that they comprise can engage resiliently engaging (two in the illustrated example), over the entire upper lid L together to allow insertion of the parts support piece 4, and the locking notch 20 as the engaging portion of the is provided (three in the illustrated example) a plurality of upper protruding part 15 can engage resiliently engaging they comprise .

  Next, the operation of this embodiment will be described.

  When attaching the lid L for closing the opening 2 to the instrument panel P, all the side support pieces 3 and the upper support pieces 4 of the lid L including the side support pieces 3 with the extension portions 10 are attached. The peripheral edge of the lid L is brought into contact with the front surface of the instrument panel P by being inserted into all the locking holes 19 and the locking notches 20 of the instrument panel P, respectively. In the process, the extension portion 10 of the side support piece 3 with the extension portion 10 having a long overall length first makes the gentle slope 13a of the projection 13 of the auxiliary claw 11 to one side edge of the corresponding locking hole 19. While sliding, it easily elastically deforms into the locking hole 19 and passes through the locking hole 19. Subsequently, all the side latching claws 6 and the upper latching claws 15 are located on the gentle slopes 8a and 17a of the respective protrusions 8 and 17 with respect to one side edge of the corresponding locking hole 19 and locking notch 20. As the slanted slopes 8a and 17a pass through the locking hole 19 and the locking notch 20, they are easily elastically deformed inwardly of the locking hole 19 and the locking notch 20. The pawl 6 and the upper latching pawl 15 are in a state of pressing the steep slopes 8b, 17b of the projections 8, 13, 17 against one side edge of the latching hole 19 and the latching notch 20 with their respective elastic restoring forces. (Refer to FIG. 2 and FIG. 6 to FIG. 8), which is in an elastic engagement state with the locking holes 19 and the locking notches 20 of the side locking claws 6 and the upper locking claws 15. Thus, the lid L can be securely attached to the instrument panel P with a relatively light pushing force toward the opening 2 side.

  In such a state where the lid L is attached, for example, when the driver or the like unintentionally touches the lower end of the lid L and pulls it strongly toward the front, the side locking claw 6 and the upper locking claw 15 The steep slopes 8b and 17b of the respective protrusions 8 and 17 are slid simultaneously with respect to one side edges of the corresponding locking holes 19 and the locking notches 20, and the locking holes 19 and the locking notches 20 By being elastically deformed inward, it is detached from the locking hole 19 and the locking notch 20. However, even if all the side portions and the upper locking claws 6 and 15 are detached, finally, as shown in FIG. 9, the protrusion 13 of the auxiliary claw 11 of the extension portion 10 has one of the corresponding engagement holes 19. By being caught on the side edge, the lid L can be prevented from falling off from the instrument panel P. Therefore, it is possible to prevent the lid L from being lost, and to make the driver recognize immediately that the lid L has been removed. Moreover, since the lid L is attached only by engaging the side and upper locking claws 6 and 15 with the locking holes 19 and the locking notches 20 without using a hinge, the mounting structure of the lid L is simplified. Therefore, the cost can be reduced.

  Next, for example, to open the lid L for maintenance of the fuse box attached to the instrument panel P facing the opening 2, the operator puts his finger on the back side of the lower end of the lid L. Then, the lid L is pulled strongly toward the front, first, the side locking claws 6 and the upper locking claws 15 are separated from the corresponding locking holes 19 and the locking notches 20, respectively, and then the lid L is further pulled. If so, the auxiliary claw 11 of the extension 10 can also be detached from the locking hole 19, so that the lid L can be completely attached to and detached from the instrument panel P.

  By the way, the extension part 10 is formed so as to be linearly continuous with the tip side of the side support piece 3, and the auxiliary claw 11 of the extension part 10 is a side locking claw of the side support piece 3. 6 is formed in the same shape and in the same orientation as the extension 6, so that the extension 10 is not restricted by the space in the opening 2, and the molding die for the side support piece 3 with the extension 10 is simplified. Can contribute to the reduction of manufacturing costs.

  As another embodiment of the present invention, the steep slope 13b of the projection 13 of the auxiliary claw 11 is formed to be steeper than the projection 8 steep slope 8b of the side locking claw 6, or the base end of the auxiliary claw 11 is formed. By increasing the bending elastic force of the auxiliary claw 11 by increasing the wall thickness, the locking force of the auxiliary claw 11 on the locking hole 19 is made larger than the locking force of the side locking claw 6 on the locking hole 19. May be set larger. In this way, it is possible to more effectively prevent the lid L from dropping from the instrument panel P without impairing the detachability of the lid L to the instrument panel P.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the present invention. For example, the extension 10 having the auxiliary claw 11 can be formed on the upper support piece 4. The locking notch 20 can be replaced with a hole. The number of the side portions and the upper support pieces 3 and 4 used and the shapes of the side portions and the upper locking claws 6 and 15 are arbitrarily selected according to the use and size of the lid L, and the extension portions. The number of supporting pieces with 10 is not limited to one, and can be arbitrarily selected according to the use and size of the lid L.
