Description

  The present invention relates to an anchor member and an anchor device using the anchor member.

  2. Description of the Related Art Conventionally, various anchor devices for fixing an object to be fastened such as a hook to a building eaves or a wall have been proposed for the purpose of suspending an object to be hung such as a fence or a screen. For example, at present, an anchor device including a shaft portion, an anchor portion fixed to one end portion of the shaft portion, and a screw portion formed at the other end portion of the shaft portion has been proposed and put into practical use. Yes.

  When the anchor device having the above structure is fixed to the wall, the shaft portion is inserted into the insertion hole provided in the wall, the anchor portion is brought into contact with one surface of the wall, and the screw portion is screwed on the other surface side of the wall. Tighten the combined nuts and fix them. Employing such a conventional anchor device requires work on both sides of the wall to secure. However, there is a problem that work on both sides of the wall is difficult for one worker and workability is poor. Further, when the board is fixed by a plurality of workers, there is a problem that work efficiency is deteriorated.

  In recent years, in order to solve such a problem, an anchor portion, a biasing member that biases the anchor portion from a parallel posture with respect to the screw shaft toward an orthogonal posture, a stopper mechanism that stops the anchor portion in an orthogonal posture, There has been proposed an anchor device having an anchor member having a ring attached to the anchor portion and screwed onto a screw shaft, and a screw hole formed in the anchor portion with the same axis as the ring (for example, Patent Document 1).

JP 2002-54619 A

  However, the anchor device having the configuration described in Patent Document 1 enables the anchor member to swing from the parallel posture to the orthogonal posture only when the screw shaft is screwed only into the ring. For this reason, there is a remarkably small allowance for the anchor member on the screw shaft, and there is a problem that the anchor member is easily detached from the screw shaft when the anchor device is attached to the board or when the anchor device is transported.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an anchor device that can more reliably prevent the anchor member from falling off the screw shaft and an anchor member used therefor.

  In order to achieve the above object, a first anchor member according to the present invention is an anchor member that is attached to a nut that is screwed into a screw shaft and can be inserted together with the nut into an insertion hole formed in the board. A nut receiving portion that rotates integrally with the nut in a state in which the nut that is screwed into the nut is received, and extends from the nut receiving portion, and the anchor member is inserted into the insertion hole, and the board A board abutting portion that abuts against the other surface of the board when moved from one surface side to the other surface side, and in a state where the nut is accommodated in the nut accommodating portion, the axial direction of the screw shaft and the board contact The board contact portion is formed by the insertion posture in which the extension direction of the contact portion is parallel and the anchor member can be inserted into the insertion hole, and the axial direction of the screw shaft intersects the extension direction of the board contact portion. A contact posture capable of contacting the other surface of the board; Guide portion for permitting relative rotation of the screw shaft and the anchor member between is intended to be formed from the nut accommodating portion to the board contact portion.

  If this structure is employ | adopted, the nut screwed together by the screw shaft can be accommodated in the nut accommodating part of an anchor member. That is, the anchor member can be attached to the screw shaft via the nut. Further, the guide member formed on the anchor member can realize relative rotation between the anchor member and the screw shaft, and the anchor member is in a state where the nut screwed to the screw shaft is housed in the nut housing portion. Thus, it can swing between the insertion posture and the contact posture. Therefore, the anchor member can be swung between the insertion posture and the contact posture even when the nut is screwed not only to the end portion of the screw shaft but also to the center portion. On the other hand, a sufficient allowance is provided, and the nut and the anchor member can be reliably prevented from falling off the screw shaft.

  In the anchor member, a pair of board contact portions may be provided so as to extend linearly in directions opposite to each other around the nut housing portion. In addition, a guide hole formed in a long hole shape from the nut housing part toward the tip of one board contact part facing the upper surface of the nut housed in the nut housing part, and opposed to the lower surface of the nut A guide portion having a guide groove formed by cutting from the nut housing portion to the tip end portion of the other board contact portion can be employed.

  When such a configuration is adopted, while the nut screwed into the screw shaft is housed in the nut housing portion, the distal end side of the screw shaft is inserted into the guide hole of the guide portion while the proximal end is located more than the nut. The anchor member having the nut accommodating portion and the board contact portion can be swung with respect to the screw shaft by inserting the side into the guide groove of the guide portion. Since the guide groove is formed by cutting out, there is no possibility of coming into contact with the screw shaft when the anchor member is swung. As a result, interference between the screw shaft and the anchor member accompanying relative rotation is avoided, and the anchor member can be smoothly swung.

  In the anchor member, the nut accommodating portion may be provided with a swing inducing portion that induces swing of the anchor member from the insertion posture toward the contact posture.

  If such a configuration is adopted, after inserting the anchor member in the insertion posture from the one surface side of the board toward the other surface side in a state where the nut is accommodated in the nut accommodating portion, the posture of the anchor member is changed by the swing inducing portion. It is possible to quickly change from the insertion posture to the contact posture that functions as an anchor.

  In the anchor member, it is possible to employ a swing inducing portion having an inclined surface that makes contact with the upper surface of the nut and makes the posture of the anchor member an inclined posture between the insertion posture and the contacting posture.

  When such a configuration is adopted, when the anchor member in the insertion posture is inserted from one side of the board toward the other side, the anchor member is released from restraint from the insertion hole. The inclined surface comes into contact with the anchor member, whereby the anchor member swings and tilts with respect to the axis of the screw shaft. By screwing the screw shaft into the nut in this state, the anchor member is pressed relatively to the other surface of the board, and the posture is gradually changed from the inclined posture to the contact posture. Eventually, the contact posture is brought into contact with the other surface of the board. As described above, the inclined surface can provide a trigger for changing the anchor member in the insertion posture to the contact posture only by the gravity acting on the anchor member.

  Further, the anchor member can be provided with a nut inlet / outlet that allows a nut screwed to the screw shaft to be freely inserted into and removed from the nut housing portion.

  If this structure is employ | adopted, a nut can be freely attached or detached from an anchor member. Therefore, after the nut and the anchor member are manufactured in separate processes, the nut is screwed onto the screw shaft, and then the nut is housed in the nut housing portion, so that the anchor member is attached to the screw shaft via the nut. The anchor device can be easily manufactured. It is also possible to convey the nut and screw shaft and the anchor member separately, and to construct the anchor device on the site.

  Further, in the anchor member, when the anchor member is swung from the insertion posture to the contact posture, the anchor member is more than the orthogonal posture in which the axial direction of the screw shaft and the extending direction of the board contact portion are orthogonal to each other. A play for swinging the member may be provided in the guide portion.

  When such a configuration is adopted, the anchor member can be in the first inclined posture that is inclined with respect to the screw axis while the insertion posture is changed to the orthogonal posture, and further, the anchor member swings more than the orthogonal posture and is screwed. The second inclined posture can be inclined with respect to the shaft, and the range in which the anchor member can be inclined with respect to the screw shaft can be expanded. As a result, even if the other surface of the board (periphery of the insertion hole) is inclined or is stepped due to the presence of other members, the anchor member is brought into contact with the other surface of the board. Can be attached.

  A second anchor member according to the present invention is an anchor member that is attached to the head of a bolt having a screw shaft and a head, and that can be inserted together with the head into an insertion hole formed in the board. A head accommodating portion that accommodates the head, and extends from the head accommodating portion, and comes into contact with the other surface of the board when the anchor member is inserted through the insertion hole and moves from one surface side to the other surface side of the board. And the anchor member is inserted so that the axial direction of the screw shaft of the bolt and the extending direction of the board abutting portion are parallel to each other in a state where the head is accommodated in the head accommodating portion. An insertion posture that can be inserted into the hole, a contact posture in which the axial direction of the screw shaft of the bolt intersects with the extending direction of the board contact portion, and the board contact portion can contact the other surface of the board; The guide portion that allows relative rotation of the screw shaft and the anchor member between the It is those formed from the contents portion the board contact portion.

  If this structure is employ | adopted, the head part of the volt | bolt which has a screw shaft can be accommodated in the head accommodating part of an anchor member. That is, the anchor member is attached to the screw shaft through the head of the bolt, and the head of the bolt is provided integrally with the screw shaft, so that the anchor member does not fall off from the screw shaft of the bolt. It can be surely prevented. Further, the guide member formed on the anchor member can realize relative rotation between the anchor member and the screw shaft, and the anchor member uses the head of the bolt screwed to the screw shaft as the head housing portion. In the accommodated state, it can swing between the insertion posture and the contact posture.

  A first anchor device according to the present invention includes a screw shaft, a nut that is screwed to the screw shaft, and an anchor member that is attached to the nut, and the anchor member is inserted through an insertion hole formed in the board. In this state, the first anchor member according to the present invention is employed as the anchor member.

  A second anchor device according to the present invention includes a bolt having a screw shaft and a head, and an anchor member attached to the head of the bolt, and the anchor member is inserted into an insertion hole formed in the board. The anchor device is fastened to the board in a state where the second anchor member according to the present invention is used as the anchor member.

  In the anchor device, an axial determining member that abuts the inner wall of the insertion hole and aligns the axis of the insertion hole with the axis of the screw shaft may be screwed onto the screw shaft.

  Since the anchor member is swingable with respect to the screw shaft, the gap between the screw shaft and the insertion hole can be swung within the swingable range even if the anchor member is brought into contact with the other surface of the board. Although the shaft can be swung, the gap is filled by the shaft determining member, so that the posture of the screw shaft in the insertion hole can be stabilized.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the anchor device which can prevent more reliably the fall of the anchor member from the screw shaft, and the anchor member used for this.

By screwing the screw shaft 10 into the nut 20 in this state, the anchor member 30 is relatively pressed against the other surface 102 of the board 100 as shown in FIGS. The posture is changed from the contact posture to the contact posture, and finally the contact posture is brought into contact with the other surface 102 of the board 100.

  By tightening the tightening member 40 in a state where the anchor member 30 is in the contact posture in this way, the board 100 is sandwiched between the anchor member 30 and the tightening member 40, and the attachment is completed. When the anchor member 30 is in the contact posture, the shaft fixing member 50 of the anchor device 1 is inserted into the insertion hole 110 of the board 100 as shown in FIG. The shaft 10 and the shaft center of the insertion hole 110 coincide with each other, and the wobbling of the screw shaft 10 is suppressed.

  In the anchor device 1 according to the embodiment described above, the nut 20 screwed into the screw shaft 10 can be accommodated in the nut accommodating portion 33 of the anchor member 30. That is, the anchor member 30 can be attached to the screw shaft 10 via the nut 20. Further, relative rotation between the anchor member 30 and the screw shaft 10 can be realized by the guide portions (the guide hole 35 and the guide groove 36) formed in the anchor member 30, and the anchor member 30 is screwed onto the screw shaft 10. In a state where the combined nut 20 is accommodated in the nut accommodating portion 33, it can swing between the insertion posture and the contact posture. Accordingly, the anchor member 30 can be swung between the insertion posture and the contact posture even when the nut 20 is screwed not only to the end portion of the screw shaft 10 but also to the center portion. Has a sufficient allowance for the screw shaft 10, and can reliably prevent the nut 20 and the anchor member 30 from falling off the screw shaft 10.

  Further, in the anchor device 1 according to the embodiment described above, the distal end side of the screw shaft 10 is guided from the nut 20 in a state where the nut 20 screwed to the screw shaft 10 is accommodated in the nut accommodating portion 33. The anchor member 30 having the nut accommodating portion 33 and the board abutting portion 34 is inserted into the guide shaft 35 by inserting the base end side of the nut 20 into the guide groove 36 of the guide portion. Can be swung. Since the guide groove 36 is formed by cutting out, there is no possibility of coming into contact with the screw shaft 10 when the anchor member 30 is swung. As a result, interference between the screw shaft 10 and the anchor member 30 due to relative rotation is avoided, and the anchor member 30 can be smoothly swung.

  In the anchor device 1 according to the embodiment described above, the anchor member 30 in the insertion posture is inserted from the one surface 101 side of the board 100 toward the other surface 102 side while the nut 20 is accommodated in the nut accommodating portion 33. Then, the posture of the anchor member 30 can be quickly changed from the insertion posture to the contact posture that functions as an anchor by the swinging induction portion (inclined portion 32b). That is, when the anchor member 30 in the insertion posture is inserted from the one surface 101 side to the other surface 102 side of the board 100, the anchor member 30 is released from restraint from the insertion hole 110. Then, the inclined portion 32 b (inclined surface) of the anchor member 30 comes into contact with the upper surface 22 of the nut 20, whereby the anchor member 30 is swung and inclined with respect to the axis of the screw shaft 10. By screwing the screw shaft 10 into the nut 20 in this state, the anchor member 30 is relatively pressed against the other surface 102 of the board 100 and gradually changes its posture from the inclined posture to the contact posture. Is brought into contact with the other surface 102 of the board 100. Thus, the inclination part 32b can give a trigger for changing the anchor member 30 in the insertion posture to the contact posture only by gravity acting on the anchor member 30.

  Moreover, in the anchor instrument 1 which concerns on embodiment described above, the nut 20 can be freely attached or detached from the anchor member 30 via a nut doorway. Therefore, after the nut 20 and the anchor member 30 are manufactured in separate processes, the nut 20 is screwed onto the screw shaft 10, and then the nut 20 is accommodated in the nut accommodating portion 33, whereby the anchor 20 is anchored via the nut 20. The member 30 can be attached to the screw shaft 10 and the manufacture of the anchor device 1 is facilitated. Moreover, it is also possible to convey the nut 20 and the screw shaft 10 and the anchor member 30 separately to configure the anchor device 1 on the site.

  Further, in the anchor device 1 according to the embodiment described above, the shaft determining member 50 that abuts the screw shaft 10 on the inner wall of the insertion hole 110 and aligns the axis of the insertion hole 110 with the axis of the screw shaft 10. Are screwed together. Since the anchor member 30 is swingable with respect to the screw shaft 10, even if the anchor member 30 is brought into contact with the other surface 102 of the board 100 in a contact posture, the gap between the screw shaft 10 and the insertion hole 110 is not affected. The screw shaft 10 can be swung within the swingable range. However, the gap is filled by the shaft determining member 50, whereby the posture of the screw shaft 10 in the insertion hole 110 can be stabilized. .
