Description

  The present invention relates to a clip, clip means including a clip and a fastening tool, and a fastening structure of a fastened member using the clip means, and in particular, to fasten a plurality of fastened members easily even in a narrow space. The present invention relates to a clip, clip means, and a fastening structure for a fastened member that can be easily fastened to a fastened member that has already been fastened.

  Inside the cockpit of an automobile, particularly under the instrument panel, a plurality of in-vehicle boxes containing electronic control computers are provided, and brackets with holes for hanging the in-vehicle boxes are fixed to each in-vehicle box. A shaft member such as a vehicle strength member is passed through the hole and is mounted on the vehicle by being tightened with a nut or the like. Therefore, when mounting an in-vehicle box, it is necessary to nut-tighten each of the in-vehicle boxes (brackets) to the shaft member. There is a problem that the number of in-vehicle boxes to be attached is limited by securing such a gap. Furthermore, in the installation work for installing the in-vehicle box in the installation space and the removal work of the in-vehicle box during maintenance of the electronic control computer, the nut tightening and nut removal in a narrow space, the installation and removal of the in-vehicle box, etc. Problems with work efficiency and prolonged work time were pointed out. For this reason, even in a narrow space, a technique that allows a fastened member such as the in-vehicle box (the bracket) to be installed as densely as possible, and a fastened member can be easily attached or detached even in a narrow space. Technology development was anxious.

  By the way, in Patent Document 1, when inserting a fastening clip into a fastening hole drilled in a member to be fastened, there is no need to worry about the directionality at the time of insertion, and the pushing force is small, and detachment workability An invention relating to an excellent fastening clip is disclosed. The fastening clip is provided with a plurality of slits in the axial direction thereof, a cylindrical portion whose distal end is freely expandable, and inserted into the cylindrical portion, and has a knob portion at one end and a long end at the other end. And a shaft body having a circular portion. For example, by rotating the knob portion with the cylindrical portion of one fastening clip passing through the holes formed in each of the two fastened members, the tip of the cylindrical portion is moved by the rotated oval portion. By expanding the diameter, the cylindrical portion presses the hole of the fastened member from the inside, so that the two fastened members can be fastened through the clip. When releasing the fastening, the tip of the cylindrical portion is reduced in diameter by rotating the knob again, so that the fastening can be easily released.

  Also, Patent Document 2 discloses an invention relating to a fastening clip that can be easily attached and requires less labor. Such a fastening clip is composed of a screw, an expandable leg portion that holds the screw from both sides, and a grommet. The screw is formed so that a large-diameter screw, a taper screw, and a small-diameter screw are continuous in the axial direction. In addition, a cross groove for cutting a tool is cut in the head of the screw. For example, insert the legs into the holes drilled in each of the two members to be fastened, lock the fastening clip with the grommet, and tighten the screws with the nail of the tool fitted in the cross groove on the head As a result, the leg portion is expanded by the screw having a gradually increasing diameter, and it is possible to fasten the two fastened members by pressing the hole from the inside.

  According to the fastening clips of Patent Documents 1 and 2, the fastening work and fastening release work of the two fastened members are simple, and the labor during the work can be reduced. However, the fastening clip of Patent Document 1 requires an operation of picking and rotating a knob with a finger, and therefore it is necessary to secure a space for at least a plurality of fingers to enter and rotate the knob. Therefore, for example, if the member to be fastened is a plate-like member and there is sufficient fastening work space and the two plate-like members are fastened via the fastening clip, the effect can be exhibited. In a narrow space, for example, in a space where it is not possible to secure a space for rotating the knob with a finger, two to three or more members to be fastened are provided, and the members to be fastened are fastened together. The effect cannot be expected in the work. The fastening clip of Patent Document 2 is also the same, and since it is necessary to secure at least a tool for screw rotation and a space for fastening with the tool, a plurality of members to be fastened in a narrow space are connected to each other. Not suitable for fastening work. In addition, in the fastening clips of Patent Documents 1 and 2, when another fastening member is further fastened to a plurality of fastening members that have already been fastened, the fastening clip is once released and all of the fastening members are renewed. Since it is necessary to re-fasten the fastening members together, it is difficult to perform such work easily. Furthermore, when the number of members to be fastened is 3 or more, it is difficult to fasten and the fastening force may be reduced.

  The present invention has been made in view of the above-described problems. A clip and a clip means that can fasten a plurality of members to be fastened and can be easily released even in a narrow space. The purpose is to provide. It is another object of the present invention to provide a clip and clip means that can be easily fastened even when another fastened member is fastened to a fastened member that has already been fastened. Further, such clips are respectively attached to a plurality of members to be fastened, and even when the number of fastened members to be fastened is increased by overlapping each clip while being pressed in the axial direction. It aims at providing the fastening structure of the to-be-fastened member which can ensure fastening force.

  In order to achieve the above object, a clip of the present invention is a clip made of a flexible material that can be attached to an opening formed in a member to be fastened, and the clip has a substantially cylindrical shape as a whole and has a central communication. A hole, a central portion having an outer diameter substantially the same as the inner diameter of the opening to be attached, and a front end portion and a rear end portion connected to the front and rear ends of the central portion having a diameter larger than the inner diameter of the opening to be attached; The rear end portion has a ring-shaped cut portion extending in the axial direction from the rear end surface. The ring-shaped cut portion reaches a part of the central portion, and the ring-shaped cut portion is expanded in the radial direction. The part that is displaced toward the inside in the radial direction by opening and that faces the central communication hole is formed with a protrusion that protrudes toward the central communication hole, and the ring-shaped notch is formed in the radial direction. By expanding to Outer part in the radial direction in relation to the ring-shaped notch portion is displaced toward the outside, the inside portion of the radial direction is characterized in that it is adapted to be displaced inward.

  The clip of the present invention can be manufactured from a flexible material such as ABS resin (a thermoplastic resin composed of three components of acrylonitrile / butadiene / styrene) or polypropylene resin. That is, a material that has both moderate flexibility that allows easy insertion into the opening of the member to be fastened, and moderate rigidity that can give a required pressing force to the rod member and the member to be fastened. It is possible to manufacture with an appropriate material.

  The clip of the present invention has a substantially cylindrical shape as a whole, and is composed of a central portion and tip and rear end portions on both sides thereof. The central portion is formed to have an outer diameter substantially the same as the inner diameter of the opening to be attached, and the outer shapes of both the front end portion and the rear end portion are formed to have a larger diameter than the outer shape of the central portion. Moreover, the clip axial direction length of a center part is shape | molded about the thickness of a to-be-fastened member. Therefore, when the center portion of the clip is fitted into the opening of the member to be fastened, the tip portion and the rear end portion on both sides thereof function as a stopper, so that the clip does not protrude from the member to be fastened.

  A ring-shaped cut portion extending in the axial direction from the rear end surface is formed in the rear end portion, and the ring-shaped cut portion reaches a part of the central portion. By setting it as such a structure, it becomes possible to expand a ring-shaped notch part to radial direction by pushing a sharp member into the notch part, for example. When the cut portion is expanded in the radial direction, the radially outer portion of the ring-shaped cut portion can be displaced outward, and the radially inner portion can be displaced inward. Therefore, by expanding the cut portion in the radial direction with a rod member such as a bolt inserted through the central communication hole, the portion outside in the radial direction from the ring-shaped cut portion is displaced outward. Thus, the outer peripheral surface of the central portion of the clip in contact with the opening of the fastened member is also displaced outward, and the outer peripheral surface of the central portion can press the opening of the fastened member. On the other hand, since the inner portion in the radial direction with respect to the ring-shaped cut portion is displaced inward, it is possible to press the bolt.

  Here, the length in the axial direction of the ring-shaped cut portion that reaches a part of the central portion is that each outer peripheral surface at least near the boundary between the rear end portion and the central portion when the cut portion is expanded. (A corner portion constituted by an end surface of the rear end portion and an outer peripheral surface of the central portion) is a length that can press the opening of the member to be fastened, and further, an inner portion of the cut portion can press a bolt or the like. It is necessary to set to such a length. However, the degree of expansion of the cut portion largely depends on the flexibility of the clip. Therefore, the length of the cut portion in the axial direction should be set in consideration of the material of the clip and the dimensions of each portion of the clip. It becomes. Also, the ring-shaped notch is excessively expanded when pressed by an adjacent clip, etc., so that the clip will not crack or plastically deform (this also depends on the clip material) It is also necessary to set

  In addition, a protrusion that protrudes toward the central communication hole is formed in a portion that is displaced inward in the radial direction by expanding the ring-shaped cut portion in the radial direction and that faces the central communication hole. ing. The protrusion protruding toward the central communication hole is one or a plurality of arbitrary shaped protrusions provided on the portion facing the central communication hole, and a rod-shaped member extending in the axial direction of the clip from the portion facing the central communication hole Is one or a plurality of arbitrarily shaped protrusions protruding further from the rod-like member toward the center of the central communication hole. This rod-shaped member may be provided at either the central portion or the rear end portion. For example, when using a threaded bolt as a rod member inserted into the central communication hole, the protrusion protrudes from the portion facing the central communication hole, so that it is more radial than the ring-shaped cut portion. When the inner portion is displaced toward the inner side, the protrusion is engaged with the screw while engaging with it, so that the clip can press the bolt while being fixed to the bolt.

  Further, the longitudinal cross-sectional shape of the rear end surface of the rear end portion is not limited to a flat surface, but may be an arbitrary shape such as a ring-shaped tapered shape or a ring-shaped curved shape that extends from the ring-shaped cut portion to the left and right oblique directions. It can be formed into a shape. When a ring-shaped cut portion is formed on a flat surface, it is necessary to insert sharp members into a plurality of portions of the cut portion in order to widen the cut portion. In the case of a ring-shaped curved shape, the cut portion can be easily expanded by pressing a member capable of pressing the surface of the shape against the tapered surface or the like.

  Further, a preferred embodiment of the clip according to the present invention is characterized in that a radial cut is further formed in the rear end portion.

  The radial cut portion is a cut portion that penetrates from the opening edge of the central communication hole to the outside in the radial direction and penetrates to the outline of the rear end face. The length in the axial direction can be set to an appropriate length such as the same length as the length in the axial direction of the ring-shaped cut portion. The number of radial cuts is preferably set in consideration of the material of the clip (flexibility and rigidity), the pressing force when the clip presses the opening of the fastening member, the bolt, and the like. .

  By forming the radial cut portion in the rear end portion, it is possible to obtain an effect that the ring-shaped cut portion is easily expanded in the radial direction.

  In addition to the rear end portion, a radial cut can also be formed at the front end portion. When the clip is fitted into the opening of the member to be fastened by the radial cut portion of the rear end part, the tip part can be easily reduced in diameter according to the opening diameter, and the clip is attached to the member to be fastened. Efficiency can be increased.

  In addition, another embodiment of the clip according to the present invention is characterized in that, in the clip, a tip portion or a convex portion is provided on a tip surface of the tip portion.

  Here, the sharp portion means a ring-shaped sharp projection provided on the tip surface or one or a plurality of sharp projections. On the other hand, the convex portion is a ring-shaped projection or one or a plurality of projections, and the tip shape thereof is a projection having a curved shape or a flat shape.

  The clip of the present invention can be used while overlapping a plurality of clips in the axial direction with the front end surface and rear end surface of adjacent clips pressed against each other. In such a mode of use, a sharpened portion that can be inserted into the ring-shaped cut portion on the rear end surface of one clip is provided on the front end surface of the other clip, so that one clip is overlapped while being pressed against the other clip. Thereby, it becomes possible to expand the ring-shaped cut portion of one clip in the radial direction. Therefore, the shape of the sharpened portion and the shape of the convex portion are preferably molded so as to match the shape of the ring-shaped cut portion on the rear end surface of the clip to be inserted, but are limited to such a shape. Instead, any shape that can expand at least the ring-shaped cut portion may be used.

  The clip means of the present invention comprises the clip, a bar member that can be inserted into the central communication hole of the clip, and a stop member attached to one end of the bar member, and the stop member has a ring shape formed on the clip. A clip means comprising a protrusion formed with a protrusion capable of expanding the notch in the radial direction, and is clipped to the central communication hole of the clip attached to the opening formed in the fastened member When the rod member of the tool is inserted and the ring-shaped notch formed in the clip is expanded in the radial direction by the protrusion formed in the stopper member, the inner portion of the clip in the radial direction is displaced inward. By doing so, the protrusion protruding toward the central communication hole is locked to the bar member.

  A protrusion formed on the stopper member constituting the fastener by inserting the rod member constituting the fastener into the central communication hole of the clip and further pressing the stopper member to the fastened member side (clip side). The ring-shaped notch formed in the clip can be expanded in the radial direction. As described above, when the ring-shaped cutout portion is expanded in the radial direction, the portion outside the ring-shaped cutout portion in the radial direction is displaced toward the outside so as to come into contact with the opening of the member to be fastened. The outer peripheral surface of the central portion of the clip is also displaced outward, and the outer peripheral surface of the central portion can press the opening of the fastened member. On the other hand, the radially inner portion of the ring-shaped notch is displaced inward, and finally the rod member is pressed in a state where the projection protruding toward the central communication hole is engaged with the rod member. be able to.

  The shape of the protrusion provided on the stop member may be any shape that can expand the ring-shaped cut portion in the radial direction. For example, a ring-shaped sharp part having the same shape as the ring-shaped cut part, or a shape provided with a plurality of sharp parts or a plurality of convex parts on a ring line having the same diameter as the ring-shaped cut part. Further, the material of the stopper may be the same material as that of the clip, or may be a different material for each constituent member. For example, the bar member can be made of a metal, and the stopper member can be made of the same ABS resin as the clip.

  In addition to the normal bolts that are spirally grooved, the rod member has a plurality of flanges in the axial direction and at least a protrusion that protrudes toward the central communication hole that is locked to the flange. As long as the shape does not deviate from the wrinkles. However, considering that it is easy to remove the fastener attached to the clip, use a bolt as a bar member, and when removing the fastener from the clip, just rotate the fastener. Can be easily released.

  The clip means of the present invention includes a case where two or more clips and one stopper are formed, in addition to one clip and one stopper. In the latter case, the rod member needs to have at least the length in the axial direction of the fastened members (or clips) fastened together. In addition, the length of the bar member can be increased in advance in consideration of a member to be fastened later.

  In the case where the clip means is composed of two or more clips and one fastener, each bracket (fastened member) fixed to a plurality of boxes containing the control device is connected via the fastener. For example, it is assumed that a single fastening bracket is used for fastening. In this case, the bar member is inserted into the central communication hole of the clip fitted in the opening of the fastening bracket, and the protrusion provided on the stopper member is pressed while being inserted into the ring-shaped cut portion of the clip. Thus, the fastener and the clip (fastening bracket) are first fastened. Next, in a state in which the clip is attached to the opening of another member to be fastened, the clip member having the ring-shaped cut portion already fastened to the fastener by inserting the stick member of the fastener into the central communication hole of the clip. The next clip is locked to the rod member of the stopper by expanding the ring-shaped cutout portion in the radial direction by the sharpened portion of the tip surface. The clips are stacked in a state of being pressed in the axial direction). Further, the next clip (a member to be fastened) is sequentially fastened through the bar member in the same manner.

  According to the clip means as described above, it is possible to easily attach the fastened member to the bar member as necessary by setting the length of the bar member in the axial direction to be long in advance. Become.

  Furthermore, in the fastening structure of the fastened member of the present invention, the clip is attached to two or more fastened members, and the bar member of one fastener is inserted in the central communication hole of all the clips in common. For clips other than the ring-shaped cutouts that are radially expanded by the protrusions formed on the stopper members of the fasteners, the front end face of the adjacent clip presses the rear end face of the clip. Thus, the ring-shaped cut portion is expanded in the radial direction, and the protrusion protruding toward the central communication hole of each clip is locked to the bar member.

  In the fastening structure of the fastened member according to the present invention, since the clip can press the fastened member and the bar member with sufficient pressing force, a plurality of fastened members are securely fastened through the bar member and the clip. It becomes possible. Further, since the clips are fastened together by pressing the next clip against the other clips, all the clips are fastened with the same fastening force even when the number of clips increases.

  As can be understood from the above description, the clip and the clip means of the present invention can be easily installed on the member to be fastened, and only by overlapping a plurality of the clips while being pressed in the axial direction, Therefore, the workability can be improved and sufficient fastening strength can be ensured. In addition, according to the clip and the clip means of the present invention, it is possible to realize fastening of more members to be fastened than in the past even in a narrow space, and other fastened to the fastened members to be fastened. The member can be easily fastened. Furthermore, according to the fastening structure of the fastened member of the present invention in which a plurality of fastened members are fastened via the clip means of the present invention, each fastened member is fastened with sufficient fastening force via the clip means. Even if the number of fastened members increases, all fastened members can be fastened with substantially the same fastening force.
