BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fixing clip for fixing a panel or a plate such as a decorative material in a superposed state.

[0002]

2. Description of the Related Art As conventional fixing clips of this kind, there are those disclosed in Japanese Utility Model Publication No. 60-18652 and Japanese Utility Model Publication No. 60-21537. Although these conventional fixing clips have some structural differences, basically, a resin female member to be engaged with a mounting round hole formed in a fixing object and an internal portion of the female member The female member includes an annular flange portion having an opening, and a cylindrical leg portion vertically provided on a lower surface of the flange portion. The cylindrical leg is divided through a slit, each divided leg is expanded outward by a male member, and small projections are formed on a wall surface that defines the internal space of the cylindrical leg. The male member has a head portion that contacts the flange portion of the female member, and a round shape that is suspended from the lower surface of the head portion and fits into the internal space of the cylindrical leg portion. A shaft portion, and a screw surface for engaging the small projection is formed on a peripheral surface of the round shaft portion.

In actual use, first, the tip of the round shaft of the male member is fitted into the internal space of the female member leg, and a small protrusion on the female member side is screwed onto the threaded surface of the shaft. After engaging the male member and temporarily fixing the male member to the female member, the cylindrical leg of the female member is inserted into the mounting round hole of the object to be fixed and temporarily fixed in the internal space of the cylindrical leg. When the shaft of the male member is completely pushed in, each split leg of the cylindrical leg expands outward,
Since the outer surface of each of the split legs is locked to the hole edge of the mounting round hole,
As a result, the state of being clamped from the inside and outside with the flange portion is obtained, and the objects to be fixed are overlapped and fixed.

[0004]

However, in the conventional fixing clip, the engagement of the small projection formed on the female member side with the screw surface formed on the male member side is, indeed, impossible.
Although it is possible to easily temporarily fix the male member to the female member, in order to fit the shaft portion of the male member into the internal space of the female member leg without difficulty, the protrusion amount of the small projection is increased. Can not do. For this reason, at the time of the temporary fixing work of the male member and the female member, not only the clear moderation feeling is not obtained, but also the temporary fixing force of the male member to the female member is naturally weakened due to the shortage of the projection of the small projection, There was a sufficient risk that the male member in the temporarily fixed state would accidentally fall off from the female member.

In the conventional fixing clip, the leg of the female member divided through a slit is formed in a cylindrical shape.
The simple locking of the outer surface of each split leg to the hole edge of the mounting round hole, even if the split leg is forcibly expanded outward by the shaft of the male member, the cylindrical leg Due to restrictions such as the outer diameter of the part must be smaller than the diameter of the mounting round hole,
Since it is difficult to firmly lock the split leg to the hole edge of the mounting round hole, the locking force on the hole edge of the mounting round hole naturally becomes weaker, and the fixing state of the fixing target is unstable. I could not deny it.

In addition, when the male member and the female member are in the final stop state, in addition to the engagement of the small projections with the screw surface in the above-mentioned temporary stop state, the thick inner end of each of the expanded split leg portions is formed. Since only the male member is pressed against the shaft surface, even in this case, the final stopping force of the male member against the female member is naturally weakened, and an external force is applied to the shaft portion of the male member in the pull-out direction. There was also a concern that the male member would easily come off the female member. For this reason, it is disclosed in Japanese Utility Model Laid-Open Publication No. 2-47414.
Improved fixing clips have been proposed. The improved type
The fixing clip is one extension in the vertical direction of the shaft of the male member.
The diameter part and the two reduced diameter parts sandwiching the enlarged diameter part are tapered.
And a plurality of holes between the upper and lower sides of the shaft.
Bulge walls are connected to each other to accommodate the one enlarged diameter part and the two reduced diameter parts.
Then, the protrusion formed on the split leg side of the female member
To temporarily fix the female and male members.
And a final stop state. For this reason, the improved type
For the fixing clip of
Compared with the male and female members, the male member and female member are temporarily
Although the strength of the state can be improved, the above configuration is adopted.
This time, in particular, the form on the male member side
As well as being complicated, of course, when obtaining the final stop state,
Even when obtaining the temporary fixing state, be sure to
Since it must be forcibly expanded outward, it is temporarily fixed
Work requires considerable power, and workability decreases
There was enough fear .

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problem of the conventional fixing clip, and is provided with a female member fixed to a mounting square hole formed in a fixing object. The female member is provided on a lower surface of a flange portion having an opening on a lower surface of a flange portion having an opening. And the lock pieces are independently provided vertically to define a fitting space for the male member inside the plate-shaped leg pieces and the lock pieces, and the outer edge of each plate-shaped leg piece has a hole edge of the mounting square hole. The locking member is formed with an inclined shoulder portion, and a stopper projection is formed on the inner surface of each lock piece. The male member is fitted into the fitting space of the female member, and the pair of plate-like legs is extended outward. A guide wall to be engaged between the pair of lock pieces is provided on the shaft to be opened. Adopting the configuration of forming the temporary fixing pawls and the locking claw portion of the stopper protrusion stepwise engagement click piece.

[0008]

According to the present invention, when the lower side of the guide wall is engaged between the pair of lock pieces, each of the stopper projections of the pair of lock pieces is brought into contact with the corresponding temporary fixing claw portion of the guide wall. Therefore, the male member can be securely fastened to the female member by the engagement between the male member and the female member. In the temporary fixing state of the male member, since the shaft of the male member has not yet acted on the pair of plate-like legs,
Each of the plate-like legs remains in its original state without any influence.

Then, the mounting square holes formed in the object to be fixed are aligned with each other, and the plate-like leg piece and the locking piece of the female member are inserted into each of the mounting square holes. When the shaft portion of the male member in the state is pushed into the fitting space of the female member, the shaft portion of the male member comes into contact with the pair of plate-shaped leg pieces, and the respective plate-shaped leg pieces are greatly expanded outward. Then, since each inclined shoulder of the plate-shaped leg piece is firmly locked to the edge of the mounting square hole, the objects to be fixed are securely fixed to each other. On the other hand,
When the shaft part of the male member is pushed into the fitting space of the female member, the stopper projections of the pair of lock pieces come off from the claw part for temporary fixing, and this time, with a sense of moderation, the claw part for permanent fixing of the guide wall. Since the female member and the male member are engaged with each other, the final stop state of the female member and the male member is reliably maintained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a fixing clip according to an embodiment of the present invention; FIG. Of the female member 1 and a male member 11 made of resin which is fitted into the female member 1. Is a square hole, and the female member 1 and the male member 11 are configured as follows.

That is, as shown in FIG. 2, when the female member 1 is provided with a leg portion on the lower surface of the flange portion 2 having the rectangular opening 2a, one opposed rectangular opening edge of the flange portion 2 is provided. A pair of long plate-shaped leg pieces 3 are vertically installed with their tip sides inclined inwardly to each other, and a pair of U-shaped cross-sections are formed at other opposed rectangular opening edges of the flange portion 2. Is vertically suspended to define a fitting space 5 for the male member 11 inside the pair of lock pieces 4.4 and the pair of plate-like legs 3.3. , A pair of plate-shaped leg pieces 3
3 has an inclined shoulder 6 which is engaged with the edge of the mounting square hole.
And a guide surface portion such as a thick portion 7 for promoting reliable expansion is formed on the inner surface side of each of the plate-shaped leg pieces 3, and a stopper projection is formed on the inner surface on the distal end side of the pair of lock pieces 4. 8 are integrally formed. In addition, each said plate-shaped leg piece 3
The width of the interval between the inclined shoulders 6 formed on the outer surface of the mounting square hole is set in consideration of the fact that the plate-shaped leg 3 is easily bent inward. Is set to be larger than the hole diameter.

[0012] The male member 11 is provided on the lower surface of the head portion 12 which is in contact with the flange portion 2 of the female member 1, in the fitting space 5.
And the square shaft portion 13 to be fitted therein
The rectangular shaft portion 13 is integrally provided with a thin guide wall 14 extending from both side portions toward the distal end portion, and the guide wall 14 is engaged between the U-shaped portions of the pair of lock pieces 4. On the other hand, two temporary fixing claws 15a and 15b are formed at a fixed interval on the lower portions on both sides of the guide wall 14, and one permanent fixing claw 16 is formed above the temporary fixing claws 15a and 15b. It is configured to be formed. Therefore, in this embodiment, the square shaft portion 13 of the male member 11 is
The guide wall 14 acts only on the lock piece 4.

Therefore, when the two panels P1 and P2 are fixed in an overlapped state by using the male member 11 and the female member 1, first, as shown in FIG. When the lower side of the guide wall 14 is engaged between the pieces 4 and 4,
While bending the tip portions of the pair of lock pieces 4 and 4 outward,
Each stopper projection 8 is connected to two temporary fixing claw portions 15a.
The male member 11 is temporarily fixed to the female member 1 because the male member 11 is temporarily engaged with the female member 1 because the male member 11 is engaged with a sense of moderation between the members 15b. When the male member 11 is in the temporarily fixed state, the shaft 13 of the male member 11 only slightly faces the fitting space 5 of the female member 1 as shown in FIG. Leg piece 3.3
Are kept in an original state inclined inwardly from each other without being affected by the shaft portion 13 at all.

Therefore, this time, the two panels P1 and P2
The mounting square holes H1 and H2 are aligned so that the mounting square holes H
When the plate-like leg piece 3 and the lock piece 4 of the female member 1 to which the male member 11 is temporarily fixed are inserted into 1 · H2, a pair of plate-like leg pieces 3 · 3 easily passes inward and passes through the mounting square holes H1 and H2, thereby temporarily locking the respective inclined shoulders 6 to the edge of the mounting square hole H1 on the panel P1 side. Therefore, after that, the head 1 of the male member 11
2, the shaft portion 13 is completely pushed into the fitting space 5 of the female member 1, and this time, as shown in FIG. 5, the shaft portion 13 becomes thicker than the pair of plate-shaped leg pieces 3.3. Each of the plate-shaped leg pieces 3 is greatly expanded outward by abutting on the meat portion 7, thereby holding the pair of plate-shaped leg pieces 3 with the inclined shoulder portions 6 and the flange portion 2 from inside and outside. By the action, the two panels P1 and P2 are securely fixed to each other.

On the other hand, when the shaft 13 of the male member 11 is completely pushed into the fitting space 5 of the female member 1, the guide wall 14 provided on the shaft 13 is also pushed into the lock piece 4. However, at this time, the stopper projection 8 of each lock piece 4 comes off from the temporary fixing claw 15b of the guide wall 14, and
This time, the final stopping claw 16 existing above the guide wall 14 is provided.
As shown in FIG. 6, the female member 1 and the male member 11 are maintained in the final fixed state by engaging with the moderation feeling on the upper surface side of the final fixing claw portion 16 as shown in FIG. Will be done.

However, in this embodiment, the male member 11
The means for temporarily fixing and permanently fixing the female member 1 and the stopper member 8 are formed on the side of the locking piece 4 of the female member 1 and the guide wall 14 of the male member 11, unlike the conventional method. Since the configuration using the three claw portions 15a, 15b, and 16 is adopted, the amount of protrusion between the stopper projection 8 and each of the claw portions 15a, 15b, and 16 is relatively small as compared with the related art. It is possible to increase it. Therefore,
Since the stopper projection 8 and the projections of the claws 15a, 15b, and 16 can securely and firmly engage with each other, a clear sense of moderation is always obtained in any state. In addition, in the temporary fixing state, there is no fear that the male member 11 is accidentally dropped from the female member 1 as in the related art, and in the final fixing state, for example, the guide of the male member 11 Even if an external force is applied to the wall 14 or the like in the detaching direction, there is no fear that the male member 11 is accidentally detached from the female member 1.

In this embodiment, as described above,
The interval width between the inclined shoulders 6 of the pair of plate-shaped legs 3 is set to be larger than the hole diameter of the mounting square holes H1 and H2. The plate-shaped leg piece 3 can easily pass through the inside of the mounting square holes H1 and H2 even if the interval width of the inclined shoulders 6 is larger than the hole diameter, because it is largely bent inward by utilizing It is possible to pass through
There is no need to worry about any problems in operation. Conversely, when the pair of plate-shaped leg pieces 3 is expanded outward through the shaft portion 13 of the male member 11, this time, the inclined shoulder portion 6 having the above-mentioned interval width is obtained.
Is firmly locked to the edge of the mounting square hole H1, and the locking force can be greatly increased. Therefore, a more reliable fixing state between the panels P1 and P2 is expected as compared with the conventional one. You can do it. Moreover, since the inclined shoulder portion 6 is formed on the outer surface of the leg 3 having a plate shape, the inclined shoulder portion 6 can be uniformly locked to the corresponding linear hole edge of the mounting square hole H1. Also from this point, the increase of the locking force is promoted.
