Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rivet that joins a plurality of plate members, and more particularly, to a detachable threaded rivet configured so that the joining can be released relatively easily by interposing a screw mechanism on the rivet.
[0002]
[Prior art]
Conventionally, when connecting a plurality of plate materials, for example, as shown in FIG. 6, a rivet 14 is used when two plate materials of a file cover 10 of a file tool and a binding substrate 12 are connected. And according to this kind of rivet, attachment is easy with a simple structure, and a firm connection can be obtained.
[0003]
[Problems to be solved by the invention]
However, this type of rivet has the following problems.
[0004]
That is, for example, when a file tool is discarded, a separate collection method has been proposed in which a paper file cover and a metal binding tool are separated and collected from the viewpoint of resource recycling. However, in conventional rivets, it has been generally impossible for a user of a file tool to easily release the rivet connection, that is, to easily remove the attached rivet. For this reason, it has been desired to improve the separation and collection with difficulty.
[0005]
Accordingly, an object of the present invention is to provide a detachable rivet having a structure that can be removed relatively easily.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a removable threaded rivet according to the present invention is inserted into a communication hole of a plurality of plate members, has a thin-walled caulking portion on the outer periphery of one end thereof, and other parts from the caulking portion. A caulking part in which a screw hole is formed toward the end, and the caulking member connected to the plurality of plate members, and having a screw shaft screwed into the screw hole at one end and the other end And a screw head member having a rivet head formed in the portion.
[0007]
And the groove part which a driver front-end | tip engages in the rivet head of this screw head member is formed.
[0008]
As described above, according to the threaded rivet of the present invention, the caulking member and the screw head member constituting the rivet can be easily detached, so that the coupling of the rivet can be easily released.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a removable threaded rivet according to the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, the same reference numerals are given to components substantially the same as those of the conventional structure shown in FIG. 6, and detailed description thereof will be omitted.
[0010]
FIGS. 1 to 5 show an example in which the threaded rivet 16 of the present invention is used to join the file cover 10 of the file tool and the binding substrate 12, and the threaded rivet 16 is a file that is a plate of two sheets. The cover 10 is composed of a caulking component 20 inserted into the communication hole 18 of the binding substrate 12 and a screw head member 22 removably coupled to the caulking component 20. The caulking member 20 has a thin caulking portion 24 on the outer periphery of one end thereof, and a screw hole 26 is formed from the caulking portion 24 toward the other end. The screw head member 22 has a screw shaft 28 screwed into the screw hole 26 at one end thereof, and a rivet head 30 formed at the other end thereof. The rivet head 30 is formed with an engaging groove 32 that engages with the tip of a driver (not shown).
[0011]
Therefore, according to the threaded rivet 16 having such a structure, after the caulking part 20 in a state where the screw shaft 28 is screwed into the screw hole 26 and the screw head member 22 is connected is inserted into the communication hole 18 (FIG. 2). ) And the caulking portion 24 of the caulking part 20 are caulked (FIG. 3), whereby the file cover 10 and the binding tool substrate 12 can be easily coupled.
[0012]
Further, as shown in FIGS. 4 and 5, the attached screwed rivet 16 of the present invention removes the screw head member 22 as indicated by an arrow a by screwing back the screw shaft 28 from the screw hole 26 ( 4), after that, the caulking part 20 is pushed out from the communication hole 18 as shown by the arrow b (FIG. 5), so that it is easily removed and the coupling of the file cover 10 and the binding substrate 12 is easily released. .
[0013]
As described above, according to the threaded rivet of the present invention, the rivet can be easily removed by releasing the caulking member and the screw head member that constitute the rivet, and a plurality of plate members can be easily released. be able to. In other words, it is possible to easily respond to the demand for resource recycling by separate collection. The threaded rivet of the present invention also has the advantage of being relatively simple.
[0014]
As mentioned above, although the file tool which consists of two board | plate materials which is the preferred Example about the screw rivet concerning this invention was demonstrated, this invention is not limited to this, It is three or more board | plate materials. Of course, the same can be applied to this case.
[0015]
【The invention's effect】
As described above, the removable threaded rivet according to the present invention is inserted into the communication holes of a plurality of plate members, and has a thin caulking portion on the outer periphery of one end portion thereof, and from the caulking portion to the other end portion. A caulking member formed with a screw hole toward the caulking member, and the caulking member connected to the plurality of plate members, and having a screw shaft screwed into the screw hole at one end and a rivet at the other end In the present invention, the rivet can be easily removed by easily detaching the caulking part and the screw shaft head part constituting the screwed rivet. The board can be easily released.
[0016]
That is, according to the present invention, a removable screw rivet that can cope with the recycling of resources by separate collection and can be configured relatively easily without changing the conventional caulking processing equipment is easy. Can be provided.
