Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fixture for fixing panel materials to each other or plate materials such as panels and decorative materials in a superposed state.

[0002]

2. Description of the Related Art As a conventional fixing device of this type, an actual flat type 4-
There is one disclosed in Japanese Patent No. 138117. Although not specifically shown, the conventional fixture is composed of two parts, a female member and a male member, which are integrally molded of synthetic resin, and the former female member is a pair on the lower surface of the flange portion having an opening. The leg pieces and a pair of lock pieces are vertically installed to define a male member fitting space inside each of the leg pieces and the lock pieces, and a shoulder portion is formed on the outer surface of the pair of leg pieces. The lock piece has a structure in which a protrusion is formed on the inner surface.

The latter male member has an enlarged head portion and a shaft portion which is pushed into the fitting space to expand a pair of leg pieces outward, and a pair of longitudinally extending portions on both sides of the shaft portion. A guide wall facing between the lock pieces is provided in a protruding manner, and an engaging claw portion that engages with the protrusion of the lock piece is formed on each guide wall.

When the two panels are fixed to each other by using both the male and female members, first, the lower side of the guide wall is faced between the pair of lock pieces, and the lock pieces of the lock pieces are connected to each other. By engaging the corresponding engaging claw portions of the guide wall with the protrusions and temporarily fixing the male member to the female member side, while matching the mounting holes formed in the two panels, The leg piece and the lock piece of the female member are inserted into the mounting hole together with the male member, and the female member is locked in the mounting hole through the flange portion and the shoulder portion of each leg piece. Then, in such a state, when the enlarged head portion of the male member is pressed and the shaft portion thereof is pushed into the fitting space of the female member, the pair of leg pieces expands outwardly. The panels of the sheets are fixed in a superposed state.

[0005]

However, under the conventional fixing tool, the pair of leg pieces provided on the female member side are forced to be expanded outward by the shaft portion of the male member, and When the shoulder portion of the leg piece is pressed against the hole edge of the mounting hole, the female part itself including the pair of leg pieces is a synthetic resin integrally molded product.
Because of its material, it is susceptible to fatigue due to temperature influences, so even if the pair of leg pieces are forcibly expanded outward, it is not possible to expect a reliable locking force for the edge of the mounting hole. It was impossible. Therefore, it cannot be denied that the fixing state between the two panels becomes unstable due to a change with time and becomes unstable.

[0006]

The present invention was developed in order to effectively solve the problem of such a conventional fixture, and is composed of a synthetic resin base and a metal spring body. The base body is provided with an enlarged head portion and a shaft portion, and defines a slit into which the metal spring body is fitted from the enlarged head portion to the inside of the shaft portion. A metal spring body is provided with a guide wall having a main stop portion, and the metal spring body has a stopper portion larger than the mounting hole formed in the plate member and a pair of bulges that hang downward from both ends of the stopper portion and bulge outward. And a pair of curved portions that are folded back inward from the lower ends of the respective bulging portions and are engaged with the temporary fixing portion and the main fixing portion in a stepwise manner.

[0007]

Therefore, according to the present invention, the metal spring body is fitted into the slit defined on the synthetic resin base body side from the enlarged head side thereof to guide each curved portion of the spring body. By engaging the temporary fixing portion of the wall, the metal spring body can be easily temporarily fixed to the synthetic resin base. Under the temporarily fixed state, since the curved portions are engaged with the narrow temporarily fixed portions, the bulging portions of the metal spring body are slightly separated from the shaft surface of the synthetic resin base body. It just bulges outward.

Therefore, when the shaft portion of the synthetic resin substrate is inserted into the mounting hole of the plate material in the temporarily fixed state, the stopper portion of the metal spring body comes into contact with the upper surface of one plate material and at the same time, Since each bulging portion of the spring body engages with the edge of the mounting hole of the other plate member, the synthetic resin substrate is temporarily fixed to the mounting hole of the plate member. Therefore, after that,
When the expanded head of the synthetic resin base is pressed, only the shaft of the base moves downward while holding the metal spring body in place, and the curved parts of the metal spring body are moved to the width of the guide wall. By engaging with a wide main stop, each bulging portion of the metal spring body is greatly bulged outwardly, so that a strong locking force with respect to the mounting hole edge of the metal bulging portion is provided. The plate materials are securely fixed without rattling.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to an illustrated embodiment. The fixture according to this embodiment is also similar to the conventional one in that it is made up of two parts, but is characterized. As shown in FIG. 1, the fixture itself is composed of a synthetic resin base body 1 and a metal spring body 11.

To explain this concretely, the former synthetic resin substrate 1 is, as shown in FIG. 2, a disk-shaped enlarged head 2 and a columnar shape extending downward from the lower surface of the enlarged head 2. Shaft 3
Is integrally provided, and a slit 4 into which the metal spring body 11 is fitted is continuously defined from the center of the enlarged head 2 to the inside of the shaft portion 3, and a plate-shaped slit 4 is formed in the slit portion 4 on the shaft portion 3 side. The guide wall 5 is provided, and a narrow temporary fixing portion 6 having both side edges largely recessed is formed in the lower part of the guide wall 5, and a wide book in which both side edges are concave on the upper part of the guide wall 5. The stopper 7 is configured to be positively formed. With respect to the slits 4, only the portion on the side of the enlarged head 2 is largely defined so as to receive the stopper portion 12 of the metal spring body 11 described later, and the height dimension of the guide wall 5 is ,
Each of the curved portions 14 of the metal spring body 11 to be described later has a temporary fixing portion 6.
The stopper portion 1 of the metal spring body 11 at the time of engaging with the
2 shall be dimensioned so that it can abut its upper end surface.

On the other hand, the latter metal spring body 11 is formed by bending one elastic metal wire, and has a linear stopper portion 12 larger than a mounting hole formed in the panel. A pair of bulging portions 13 that hang downward from both ends of the stopper portion 12 and bulge outward, and a temporary fixing portion 6 of the guide wall 5 that is folded back upward from the lower end of each bulging portion 13.
And a pair of bending portions 14 that are engaged with the main stopper 7 in a stepwise manner. The pair of bulging portions 1
The interval width of 3 is set to be slightly larger than the diameter of the shaft portion 3 of the synthetic resin substrate 1. Also, the spring body 11
It is also possible to mold itself by using a metal leaf spring material or the like.

Therefore, when the two panels P1 and P2 are fixed by using the synthetic resin substrate 1 and the metal spring body 11 having such a structure, first, the stopper portion 12 of the metal spring body 11 is fixed. When the metal spring body 11 is fitted from the enlarged head 2 side into the slit 4 defined on the synthetic resin base body 1 side until the abutment contacts the upper end surface of the guide wall 5, each bending of the spring body 11 Since the portion 14 can be automatically engaged with both side edges of the narrow temporary fixing portion 6 of the guide wall 5, the metal spring body 11 can be easily temporarily attached to the synthetic resin base body 1 as shown in FIG. Will be stopped. Under the temporarily fixed state, each bending portion 14
Is engaged with the narrow temporary fixing portion 6, each bulging portion 13 of the metal spring body 11 is slightly bulged outward from the surface of the shaft portion 3 of the synthetic resin base 1. is there.

Therefore, after the provisionally fixed state is obtained, the respective mounting holes H1 and H formed in the two panels P1 and P2.
When the shaft portion 3 of the synthetic resin substrate 1 is inserted into the mounting holes H1 and H2 by utilizing the tapered shape while aligning the two, as shown in FIG. At the same time as it abuts on the upper surface of the panel P1 of each of the above, the respective bulging portions 13 of the metal spring body 11 are locked to the hole edges of the mounting holes H2 of the other panel P2.
The synthetic resin substrate 1 is temporarily temporarily fixed to the mounting holes H1 and H2.

Finally, when the enlarged head 2 of the synthetic resin substrate 1 is pressed downward, as shown in FIG. 5, while the metallic spring body 11 is held in place, the enlarged head 2 has one panel. Only the shaft portion 3 of the base 1 moves downward in the mounting holes H1 and H2 until it abuts the P1 surface, and the stopper portion 12 of the metal spring body 11 is housed in the slit 4 on the enlarged head 2 side. At the same time, since the pair of curved portions 14 engage with both side edges of the wide main stopper portion 7 of the guide wall 5, the main stopper portion 7 is formed.
By the slide engagement with respect to each other, the respective bulging portions 13 of the metal spring body 11 are forcibly bulged outwardly, and the other panel P
2 is strongly locked to the edge of the mounting hole H2. Therefore, under the present embodiment, unlike the conventional one, the metal bulging portion 13 is locked to the hole edge of the mounting hole H2 with a strong locking force. As a result, there is no concern about heterals, and it is possible to continue to ensure a reliable overlapping and fixing state of the two panels P1 and P2.

Further, when it becomes necessary to release the fixed state of the two panels P1 and P2, the enlarged head 2 of the synthetic resin substrate 1 is pryed up with a tool or the like to obtain the above. Is the opposite action, each curved portion 14 of the metal spring body 11 engages with the narrow temporary fixing portion 6 of the guide wall 5, and the pair of bulging portions 1
Since the large bulge of 3 toward the outside is released, if the synthetic resin base body 1 is pulled out together with the metal spring body 11 from the mounting holes H1 and H2 in such a state, two panels P
It is possible to easily release the fixed state of 1 · P2. In addition, in this case, it is needless to say that the pair of bulging portions 13 that bulge slightly outward are only bent inward, so that workability is also improved, but the pair of bulging portions 13 is not required.
Since there is no concern about deformation, it can be reused sufficiently.

[0016]

As described above, the present invention is different from the conventional one and is characterized in that the plate members are fixed in a superposed state by utilizing the locking force obtained from the metal spring body. Therefore, since there is no concern about heat generation due to the influence of temperature, it has become possible for the first time to continuously guarantee the secure fixing state of the plate materials regardless of the change over time. In addition, structurally, it can be reused sufficiently, so that it is possible to meet the current request for rationalization.
