便なものでよいという利点がある。Conventional technology It consists of a hollow elastic tubular body with a flange formed at one end and an inelastic nut member fixed at the other end.When the bolt member is screwed in from the flange side, it deforms so that the intermediate part expands in diameter. A caulking nut having a structure capable of holding a panel or the like in cooperation with the flange is known. This caulking nut is convenient because it can be attached from one side to a hole in a panel or the like, similar to a fastener known as a blind nut made of a rigid material such as metal. Compared with the blind nut, since the tubular body is made of an elastic body, there is an advantage that a tool for expanding the tubular body may be a simple tool such as a screwdriver.
考案が解決しようとする課題 しかしながら、このかしめナットにも解決すべき課題が
ある。すなわち、ブラインドナットと比較すると、筒状
体が弾性材で成るので、ボルト部材の締め込み力が強い

然にパネル等の挟持力も弱くなる。かかる不具合の解消
のため、非弾性のナット部材から筒状体内部をフランジ
方向に延びる剛性の筒に形成された補強部を有するもの
も考案された。Problems to be Solved by the Invention However, this caulking nut also has problems to be solved. That is, compared with the blind nut, the tubular body is made of an elastic material, so if the tightening force of the bolt member is strong, the expanded diameter part will break, and conversely if the tightening force is weak, it will naturally clamp the panel etc. The power also weakens. In order to eliminate such a problem, a device having a reinforcing portion formed from a non-elastic nut member into a rigid cylinder extending in the flange direction inside the cylindrical body has been devised.
この補強部は剛性を有するので、筒状体の弱い部分を補

ジと筒状体拡径部との間に挟持するパネル等の厚さによ
って、拡径部が大きくなったり、小さくなったりして、
その保持強度が異なるという不具合があった。Since the reinforcing portion has rigidity, it is possible to reinforce the weak portion of the tubular body and thereby prevent the expanded diameter portion of the tubular body from breaking. However, even with this caulking nut, depending on the thickness of the panel or the like that is sandwiched between the flange and the expanded diameter portion of the tubular body, the expanded diameter portion may become larger or smaller,
There was a problem that the holding strength was different.

った。Further, in order to insert the bolt member penetrating the connecting member connected to the panel, it is desirable that the bolt member insertion hole of the connecting member is large. However, in order to make full use of the effect of the reinforcing portion, the connecting member has to abut against the end portion of the reinforcing portion, so that there is a constraint that the insertion hole must be smaller than the outer diameter of the reinforcing portion. However, there is a problem that it hinders the smooth insertion work of the bolt member. Furthermore, if the contact area between the end portion of the reinforcing portion and the connecting member is small, the caulking nut itself does not rotate even if the bolt member is rotated. There was also a drawback that it could not be tightened sufficiently with the rotation.

とするかしめナット用保護具が提供される。Means for Solving the Problems To achieve the above object, according to the present invention, a flange is formed at one end and a non-elastic nut member is fixed at the other end. When a bolt member is screwed in, it is a protector for a conventional caulking nut that is deformed so that the intermediate portion expands in diameter and can cooperate with the flange to clamp a panel or the like, and has a hollow rigidity with a flange at one end. The protector is formed of a tubular body, the inner diameter of which is such that the bolt member can be inserted therein, and the outer diameter of which is fitted inside the tubular portion of the crimp nut. The flange is formed to be larger than the inner diameter of the caulking nut tubular body portion, and the protector tubular body portion is inserted and fixed in the caulking nut tubular body portion until the flange abuts the caulking nut tubular body portion. There is provided a caulking nut protector characterized by:

Expand the diameter. The expanded diameter portion 6 cooperates with the flange 2 to perform a function of holding the panel 7 or the like, and by this holding, the caulking nut 1 is fixed to the panel 7. Panel 7
By using the caulking nut 1 fixed to the above, and sandwiching the connecting member 8 between the bolt member 5 and the flange 2,
The connecting member 8 can be connected to the panel 7.

がかしめナット筒状体４に固定される。Referring again to FIG. 1, the structure of the protector 10 according to the present invention will be described. The protector 10 is a hollow rigid tubular body having a flange 11 at one end. The inner diameter of the hollow tubular protector 10 is formed so that the bolt member 5 can be inserted therein.
Further, the outer diameter of the protector 10 is formed so that it can be fitted and fixed inside the caulking nut tubular body 4. Typically, the outer diameter is formed to be slightly larger than the inner diameter of the tubular body 4. Also, the flange 11 of the protector 10 is the crimp nut 1
Is formed larger than the inner diameter of the tubular body 4. With this configuration, when the tubular protector 10 is inserted into the tubular body 4 of the crimping nut 1, the protective tool tubular body portion 12 with the flange 11 in contact with the flange 2 of the crimping nut 1 is inserted.
The caulking nut is fixed to the tubular body 4.

定のかしめナットに挿入して固定すればよい。The length of the tubular body portion 12 of the protector depends on the thickness of the panel 7 to be fixed so that the expanded diameter portion 6 of the tubular body 4 of the caulking nut 1 is located at an appropriate position as shown in FIG. Selected to be formed. Therefore, it suffices to prepare protective tools of various lengths according to the thickness of the panel 7 and insert the protective tool suitable for the plate thickness into a predetermined caulking nut to be fixed.

に食い込ませるようにしてもよい。Further, in order to fix the protector 10 to the caulking nut 1, for example, the outer diameter of the protector tubular portion 12 is made slightly larger than the inner diameter of the tubular body 4 of the caulking nut 1 so as to be fixed by firm fitting. In this fixing, as shown in FIGS. 4 and 5, it is preferable that the flange 11 of the protector 10 is provided with a ridge projection 13 extending in the radial direction to prevent the caulking nut from rotating with respect to the flange 2. To prevent this rotation, a protrusion 14 is formed on the end of the protective device tubular body portion 12 opposite to the flange 11.

を確実にパネルに固定できる。Effect of the Invention By simply fixing the new protector according to the present invention to the conventional caulking nut, even if the caulking nut tubular body is tightened and expanded by screwing the bolt member, this protector The expanded part of the tubular body of the caulking nut made of an elastic body that acts as a reinforcing means is prevented from breaking, so that it can withstand a high tightening force, and the protector flange has a caulking nut flange. As well as the connecting member surely comes into contact with this protector flange,
When the bolt member is screwed in, the caulking nut is also securely prevented from rotating together with the bolt member. The protector according to the present invention can be easily fixed by inserting it into the caulking nut. Therefore, by providing a protector of a length selected according to the thickness of the panel, it is suitable for the thickness of the panel. A diametrically expanded portion is formed at the position, so that the caulking nut can be securely fixed to the panel.
