Description

  TECHNICAL FIELD The present invention relates to a clip nut that is inserted into an edge of a plate member and is used so as to sandwich the plate member, and particularly relates to a clip nut having a large applicable range capable of dealing with plate members having different thicknesses. .

Various types of clip nuts have been proposed in which a nut is attached to an upper piece of a clip formed by bending a thin metal plate into a flat U shape (see, for example, Patent Document 1 and Patent Document 2).

  The use of the clip nut is roughly divided into a case where a thin plate is fastened to a base plate material and a case where two thin plates are fastened together, and the base plate material has a thickness of 3.2 mm to 10.0 mm, and the thin plate has a thickness of 0.0. A plate member of 5 mm to 1.6 mm is most often used.

  On the other hand, the conventional clip nut has a narrow range of applicable plate member thicknesses, and the position of the mounting hole provided in the plate member (distance from the edge) differs. Is provided.

  However, there is a limit to stocking many types of clip nuts in this way, and in fact, it takes the form of order production, but for this reason, there are delays in delivery, high manufacturing costs, inventory management, etc. Various problems have occurred.

On the other hand, the position of the attachment hole provided in the plate member to which the clip nut is applied is specified in several types such as 15 mm, 20 mm, and 25 mm from the edge. For this reason, if clip nuts that can handle multiple plate members with different thicknesses are developed, they can be stocked, and problems such as high manufacturing costs and delays in delivery due to small-lot production orders are resolved. It will be.
Japanese Patent No. 2877806 No. 7-40724

  The present invention has been made in view of the above-mentioned conventional problems, and it is possible to provide a clip nut having a large range of applicable plate thicknesses, in which one type of clip nut can correspond to several types of plate members having different thicknesses. Objective.

  In order to achieve the above object, the present invention provides a clip formed by bending a thin metal plate into a flat U-shape, and an upper piece and a lower piece facing each other. A clip nut in which a nut is attached to the upper piece part and a bolt insertion hole that is screwed into the nut is provided in the lower piece part, and the upper piece part surrounds the three sides of the nut. A nut support that is provided with a notch extending in a U-shape along both the bent portion side and both side edges, and is continuous with the end edge portion on the free end side of the upper piece portion and extends substantially parallel to the lower piece portion. Is formed coaxially with the screw hole of the nut, and the protruding end surface of the positioning cylinder portion protruding from the nut support portion toward the lower piece portion is inclined toward the edge portion, The terminal end is substantially flush with the lower surface of the nut support portion.

  The clip is disposed such that the lower piece portion is substantially perpendicular to the axis of the nut, and the upper piece portion is inclined downward so that the end edge portion is closer to the lower piece portion than the bent portion. An arrangement is preferred.

  The clip nut of the present invention having the above-described configuration has different thicknesses from a thin plate to a thick plate having a thickness corresponding to the height between the upper piece portion and the lower piece portion inside the bent portion. It can be applied to a plurality of types of plate members. That is, in the case of a thin plate, the plate member (thin plate) is rattled by pushing the nut support portion toward the lower piece portion and narrowing the interval between the nut support portion and the lower piece portion. Can be installed without. Further, in the case of a thick plate, the end edge portion of the upper piece portion is pushed and expanded so as to be inserted into the plate member (thick plate). At this time, the protruding end surface of the positioning cylinder portion is the end portion. The edge of the plate member is hooked on the positioning cylinder portion when it is inserted into the plate member because it is inclined toward the edge portion and the terminal end is substantially flush with the lower surface of the nut support portion. There is no, and can be inserted and installed smoothly.

  According to the present invention, since one type of clip nut can handle a plurality of plate members having different thicknesses, all plate thicknesses can be handled only by manufacturing several types of clip nuts. Therefore, inventory becomes possible, and problems such as high manufacturing costs and delays in delivery due to order production of small lots can be solved.

  In addition, the clip nut of the present invention can be mounted smoothly and without rattling regardless of the thickness of the plate member to be applied, and is excellent in terms of use and handling.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show a clip nut 1 according to the present invention. The clip nut 1 is formed by bending a thin metal plate into a flat U-shape or U-shape, and a clip 2 in which an upper piece portion 3 and a lower piece portion 4 facing each other are connected to the bent portion 5. And a nut 10 fixed to the upper piece 3 of the clip 2.

  The upper piece 3 is provided with a notch 6 extending in a U-shape along the bent portion 5 side and both side edges so as to surround three sides of the nut 10, and the edge of the upper piece 3 on the free end side A nut support portion 8 that is continuous with the portion 7 and extends substantially parallel to the lower piece portion 4 is formed, and the nut 10 is welded and fixed to the nut support portion 8.

  The nut 10 is provided with a positioning cylinder portion 12 that protrudes coaxially with the screw hole 11. The positioning cylinder portion 12 penetrates through the nut support portion 8 and protrudes toward the lower piece portion 4, the protruding end surface 13 is inclined from the central portion toward the end edge portion 7, and the terminal end 14 of the inclined end surface 13 ′ is nut-supported. It is substantially flush with the lower surface of the portion 8.

  Since the nut support portion 8 is substantially parallel to the lower piece portion 4, the axis of the nut 10 fixed to the nut support portion 8 is disposed substantially orthogonal to the lower piece portion 4. The lower piece 4 is provided with a guide elongated hole 9 that faces the positioning cylinder portion 12 of the nut 10 and extends in the longitudinal direction.

  Further, the upper piece 3 is disposed so as to be inclined downward so as to approach the lower piece 4 from the upper end of the bent portion 5, and the end edge portion 7 faces upward to facilitate the insertion of a plate member described later. It is bent.

  In the illustrated embodiment, the nut 10 is a locking nut provided with an elastic ring 15 of locking means at the top, but may be a normal nut.

  4 and 5 show a use state of the clip nut 1 having the above-described configuration.

  FIG. 4 shows an example in which two thin plates 21 and 22 are overlapped and fastened. The clip 2 is inserted so as to sandwich the thin plates 21 and 22, and the positioning cylinder portion 12 is engaged with the mounting hole 23. The screw hole 11 of the nut 10 is positioned and held at a predetermined position facing the mounting hole 23. When the clip 2 is inserted into the thin plates 21 and 22, the clip 2 is guided to the end edge portion 7 and the inclined end surface 13 ′ of the positioning cylinder portion 12, and smoothly inserted to a predetermined position where the positioning cylinder portion 12 engages with the mounting hole 23.

  FIG. 5 shows an example of use mounted on a thick base plate 25. Also in this case, when the clip 2 is inserted into the base plate 25, it is guided to the edge 7 and the inclined end surface 13 'of the positioning cylinder part 12 and smoothly reaches a predetermined position where the positioning cylinder part 12 engages with the mounting hole 26. Can be plugged in. Further, the plate member that can be attached to the clip nut 1 can be attached to the base plate material 25 having a thickness corresponding to the height H between the upper piece 4 and the inner side of the bent portion 5 to the maximum. is there.

  FIG. 6 shows a clip nut 1 ′ in which the height h inside the bent portion 5 of the clip 2 is about ½ of the height H of the clip nut 1 shown in FIGS. 1 to 5.

  Therefore, when H = 10 mm and h = 5.0 mm are set, the clip nut 1 can accommodate plate members having a thickness of 4.5 mm to 10 mm, and the clip nut 1 ′ is in the range of 0.5 mm to 4.5 mm. It can be applied to a plate member, and can be applied to various plate members having a thickness of 0.5 mm to 10 mm with two types of clip nuts 1, 1 ′. In addition, if several types of clip nuts 1 and 1 'that can correspond to plate members with different positions (distances from the edge) of the mounting holes 23 and 26 are manufactured, they can be compatible with most plate members, so that they can be stocked and manufactured. Problems such as high costs and delays in delivery can be solved.
