Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to an article attachment for attaching an article such as a handrail to the surface of a wall surface constituting member.
[0002]
[Prior art]
  When attaching an object such as a handrail to the surface of the wall surface component, if the wall surface component is brittle, for example, gypsum board, it is attached from the surface side of the wall surface member attachment (surface on which the article is located) If the article is attached with a screw or the like, it becomes impossible to support a large load from the article and it cannot be adopted. For this reason, an opening (becomes extending in the lateral direction) is formed in the wall surface component member, the anchor piece is inserted through the opening portion, and the article is fixed to the back surface side of the wall surface component member. The load from is carried out. In this case, since the opening is required to be as small as possible, the anchor piece can be inserted through the opening having a small diameter, and how large a load can be supported can be constructed easily. It is important to do so.
[0003]
  2. Description of the Related Art Conventionally, various articles fittings using an anchor piece inserted through an opening have been proposed. In Japanese Patent No. 2903313, a pair of anchor pieces each having an elongated plate shape is used, and each anchor piece including the anchor shaft is inserted through an opening formed in the wall surface constituting member as a whole. . After the insertion, the pair of anchor pieces are developed so as to form a cross shape by a spring incorporated in advance. And the wall surface component member is clamped by the surface side member and a pair of anchor piece which were located in the surface side of the opening part with the attachment volt | bolt screwed together by the anchor shaft. In such construction, the assembly of the pair of anchor pieces including the spring and the anchor shaft has a holding string in advance so that the pair of anchor pieces inserted through the opening and the anchor shaft do not fall. It is connected and the holding string is always gripped from the surface side of the wall surface constituting member, thereby preventing the assembly from dropping.
[0004]
  In JP-A-9-209538, a mounting bolt is slidably attached to an elongated plate-like linearly extending anchor piece, and the mounting bolt is anchored to the opening formed in the wall surface constituting member. Performed from the opposite end of the mounting bolt in the state of being positioned at the end of the piece, and after inserting the anchor piece into the opening, the position of the mounting bolt is positioned approximately in the middle of the anchor piece in the longitudinal direction. Is disclosed.
[0005]
[Problems to be solved by the invention]
  However, in the thing of the above-mentioned patent 2903313 gazette, since a holding | maintenance string must always be hold | gripped during construction, it becomes a thing with bad workability. Further, although the pair of anchor pieces are deployed by the spring so as to form a cross shape, it is practically difficult to control this deployment from the front surface side of the wall surface constituent member. Depending on the position of a certain pillar, it may not be developed in a cross shape, and the orientation of the pair of anchor pieces at the time of expansion cannot be controlled from the surface side of the wall surface constituting member. Further, since the anchor shaft is positioned at the middle portion in the longitudinal direction of the anchor piece, the anchor piece is in contact only in the vicinity of the peripheral edge portion of the opening formed with the trowel with respect to the wall surface component (the contact area cannot be increased). Therefore, the load bearing ability is low.
[0006]
  Moreover, in the thing of the above-mentioned Unexamined-Japanese-Patent No. 9-209538, the operation | work of position adjustment with respect to the anchor piece of a mounting bolt after insertion to the opening part of an anchor piece becomes troublesome, and workability | operativity is bad. In order to prevent the assembly of the anchor piece and the mounting bolt from falling, a holding string as described above is separately required, and the workability is further deteriorated. In addition, since the anchor piece simply extends linearly, the anchor shaft limits the load bearing direction. Further, even in this publication, the mounting bolt is positioned at the middle portion in the longitudinal direction of the anchor piece, so that the load bearing ability is low for the same reason as described above.
[0007]
  The present invention has been made in view of the above circumstances,Its purpose isIt is designed to support the load from the article by using the anchor piece inserted through the opening formed in the wall surface component. It is easy to install, has high load support capability, and is installed regardless of the position of the stud. It is an object of the present invention to provide an article fixture.

TheIt is like that. A preferred mode based on the above-described solution method is as follows.Claims 2 to 7It is as described in.
[0009]
【The invention's effect】
  According to the first aspect of the present invention, since each anchor piece is prevented from falling to the back side of the wall surface constituting member by using the surface side member, the anchor piece is not always dropped by the holding string or the like. Compared with the case where it is made, the workability is excellent. Also, since the mounting bolt is located at the base end of each anchor piece, each anchor piece can be easily inserted through the opening, making the workability easier, and making each anchor piece longer. It is possible to increase the load bearing capacity. In addition, the second anchor piece normally extends vertically downward due to gravity, and when there is a stud, it is stopped at a position in contact with the stud, while the first anchor piece is optional by rotating a mounting bolt. In other words, the first anchor piece can be set to extend in a direction different from that of the second anchor piece as much as possible. This means that the direction of extension of the second anchor piece is set in the most preferable direction by setting the extension direction of each anchor piece as different as possible to enhance the load bearing capacity as a whole, or taking into consideration the direction of load application to the article. In this sense, the load bearing ability can be increased. In addition to this, by simply tightening the lock nut, it is possible to obtain a state in which the wall surface constituting member is sandwiched between each anchor piece and the surface side member. From this point, workability is also improved.
[0010]
  Also,Because the anchor piece can be made long and its tip is curved almost horizontally,Load bearing capacityTheThe load bearing direction can be set in two directions, and the direction in which the anchor piece extends can also be set as desired.
[0011]
  Claim2According to the invention described in the above, the surface-side member can be positioned using the opening, and the load can be distributed and received on the inner peripheral surface of the opening, that is, the wall surface constituent member via the surface-side member. .
[0012]
  Claim3According to the invention described in the above, the flange portion can more reliably prevent the front surface side member from moving to the back surface side, and the appearance around the opening can be improved.
[0013]
  Claim4According to the invention described in the above, it is possible to increase the load bearing capacity by increasing the area of the distal end portion where the load bearing capacity is large at a position far from the base end of the anchor piece to which the load is applied. it can. The tip of the anchor piece can be widened to a degree slightly smaller than the diameter of the opening.
[0014]
  Claim5According to the invention described in the above, it is preferable that the anchor piece base end portion and the tip end portion are firmly brought into contact with the back surface side of the wall surface component member to sufficiently exert the load supporting ability by the anchor piece. It becomes. That is, when the lock nut is tightened, the anchor pieceWorking mounting boltIt is conceivable that there is a considerable amount of elastic deformation due to the tensile force through the anchor, but even in this elastically deformed state, the tip of the anchor piece strongly contacts the back surface of the wall component member.Let meThe state can be secured and the load bearing ability can be fully exhibited.
[0015]
  Claim6According to the invention described in (1), the rotation operation of the mounting bolt, that is, the operation for setting the extending direction of the first anchor piece can be easily performed using the fitting portion having an irregular cross section. It is also possible to know the extending direction of the second anchor piece by looking at the rotational position of the fitting portion.
[0016]
  Claim7According to the invention described in (4), it is preferable to make the anchor piece as long as possible while allowing insertion into the opening. In particular, it is suitable when the rear surface side of the wall surface constituting member has only a small interval in the insertion direction of the anchor piece.
[0017]

  1-3 which show 1st Embodiment of this invention, FIG. 1, FIG. 2 shows the article | item fixture M of the state attached to the wall surface structural member H, FIG. 3, FIG. The article attachment tool M before attachment is shown. The components of the article attachment M will be described first. The article attachment M includes a first anchor piece 1, a second anchor piece 2, an attachment bolt 3, a surface side member 4, and a lock nut 5. Each of the anchor pieces 1 and 2 is formed as a whole by an elongated metal material (for example, a steel plate) or a synthetic resin having a rigidity of several millimeters, and each of the anchor pieces 1 and 2 has an outer peripheral shape as a whole. Are almost congruent. The shapes of the anchor pieces 1 and 2 will be described in detail later.
[0018]
  The mounting bolt 3 is penetrated so that the base end portion of the first anchor piece 1 is orthogonal to the plate surface, and the first anchor piece and the mounting bolt 3 are fixed so as to rotate integrally with each other by welding or caulking. Yes. The head 3a of the mounting bolt 3 is located on the back side of the first anchor piece 1 (on the back side, the left side in FIG. 1). A base end portion (a mounting hole formed therein) of the second anchor piece 2 is rotatably fitted to the mounting bolt 3 on the distal end side of the mounting bolt 3 with respect to the first anchor piece 1. . That is, the second anchor piece 2 is rotatable relative to the first anchor piece 1 and the mounting bolt 3.
[0019]
  Details of the mounting bolt 3 are shown in FIG. 15 to FIG. 18, and the outer peripheral shape of the tip portion thereof is, for example, notched at an equally spaced position of about 180 degrees to form the rotational input portion 3 b having an irregular cross section. A rotating jig described later can be engaged so as not to be relatively rotatable.
[0020]
  As shown in FIGS. 13 and 14, the surface side member 4 is formed in a plate shape as a whole by press-molding a metal material having excellent rigidity such as an iron plate. That is, the surface-side member 4 includes a disk-shaped substrate portion 4a, a side wall portion 4b as a fitting portion that extends substantially at right angles from the outer peripheral edge portion of the substrate portion 4a and has a generally short cylindrical shape, A through hole 4d that has a flange portion 4c that extends from the tip end of the portion 4b to the radially outward side of the substrate portion 4a, and through which the mounting bolt 3 penetrates in a substantially central portion of the substrate portion 4a. Is formed.
[0021]
  The front surface side member 4 is positioned closer to the distal end side of the mounting bolt 3 than the anchor pieces 1 and 2. A lock nut 5 is screwed onto the mounting bolt 3 further on the tip side of the mounting bolt 3 than the surface side member 4.
[0022]
  The wall constituting member H is formed with an opening 10 for attaching the article fixture M. As shown in FIGS. 1 and 2, when the article fixture M is attached to the wall surface constituent member H, each anchor piece 1, 2 is inserted through the opening 10 and positioned on the back side of the wall surface constituent member H. Is done. The mounting bolt 3 passes through the opening 10, and the tip thereof extends to the surface side of the wall surface constituting member H. The front surface side member 4 has a side wall portion 4b fitted into the opening portion 10 without rattling, and a flange portion 4c abutted against the outer peripheral edge portion of the opening portion 10 (the diameter of the side wall portion 4b is open). The diameter is approximately the same as the diameter of the portion 10, and the maximum diameter of the flange portion 4 c is set larger than the diameter of the opening 10). The lock nut 5 is tightened so as to strongly come into contact with the substrate portion 4a of the surface side member 4. By tightening the lock nut 5, the wall surface constituting member H is strongly sandwiched between the two anchor pieces 1 and 2 and the surface-side member 4 that are at different relative rotational positions. Thereby, the mounting bolt 3 is firmly held by the wall surface constituent member H, and an article such as a handrail positioned on the surface side of the wall surface constituent member H is attached using the mounting bolt 3.
[0023]
  Next, for each of the anchor pieces 1, 2, particularly its shape, FIG.See FIG.However, it will be explained. First, the first anchor piece 1 is shown in FIGS. As for this 1st anchor piece 1, the base end part is shown by the code | symbol 1a, the front-end | tip part is shown by the code | symbol 1b, and the intermediate part which connects the both ends 1a and 1b is shown by the code | symbol 1c. The base end portion 1a is slightly offset toward the back surface side (the head 3a side of the mounting bolt 3) with respect to the intermediate portion 1c, and the plate surface on the surface side of the base end portion 1a is It is slightly displaced toward the head 3a side of the mounting bolt 3 with respect to the surface side plate surface, and this deviation amount, that is, the amount of the offset is the same as the thickness of the substrate portion of the second anchor piece 2.
[0024]
  The intermediate portion 1c and the tip portion 1b are set so that the plate surfaces on the surface side thereof are substantially flush. However, the plate surfaces on the surface side of the intermediate portion 1c and the tip portion 1b are arranged so that the mounting bolts 3 move toward the tip portion 1b.TipIt is slightly inclined so as to be directed to the side (the above-mentioned inclination can be obtained by slightly bending the vicinity of the boundary between the intermediate portion 1c and the base end portion 1a toward the distal end side of the mounting bolt 3). This inclination prevents a situation in which the tightening force of the lock nut 5 acts in the vicinity of the base end portion 1a in the state where the attachment of the article fixture M to the wall surface component H shown in FIG. This is to ensure that the distal end portion 1b is firmly pressed against the back surface of the wall surface constituting member H from 1c to the distal end portion 1b. Due to the inclination setting, a slight gap may be formed in the portion of the intermediate portion 1c near the base end portion 1a with respect to the back surface of the wall surface constituting member H.
[0025]
  The intermediate portion 1c is generally curved in a substantially arc shape (actually, a curve in which a plurality of arcs having different curvature radii are continuous), but the degree of curvature is relatively small. Moreover, the front-end | tip part 1b is largely curved by about 90 degree | times laterally with respect to the centerline of the intermediate part 1c. As a result, the direction extending from the base end portion 1a to the intermediate portion 1c and the direction in which the tip end portion 1b extends are different from each other by nearly 90 degrees, so that the length of the tip end portion 1b is as long as possible. Is set to Moreover, the width | variety of the front-end | tip part 1b is made larger than the width | variety of the base end part 1a and the intermediate part 1c. 5 to 8, 1d is a mounting hole through which the mounting bolt 3 (the shaft portion thereof) passes.
[0026]
  As shown in FIGS. 9 to 12, the second anchor piece 2 is formed in a shape substantially similar to that of the first anchor piece 1. That is, the base end portion corresponding to the base end portion 1a is indicated by reference numeral 2a, the tip end portion corresponding to the tip end portion 1b is indicated by reference numeral 2b, and the intermediate portion corresponding to the intermediate portion 1c is indicated by reference numeral 2c. A mounting hole corresponding to the hole 1d is indicated by reference numeral 2d. However, the base end portion 2 a of the second anchor piece 2 is offset so as to slightly protrude toward the tip end side of the mounting bolt 3. That is, in the mounting completion state shown in FIG. 1, the base end portion 2 a of the second anchor piece 2 is fitted to the inner peripheral surface of the opening portion 10 almost without shakiness, and the mounting bolt 3 is The load downward from the article can be transmitted from the base end portion 2a of the second anchor piece 2 to the inner peripheral surface (low portion) of the opening 10.
[0027]
  19 to 22 show an example of the rotating jig 20 for rotating the mounting bolt 3. The rotating jig 20 is engaged with an elongated main body portion 20a and a rotation input portion 3b formed on the front end surface of the main body portion 20a and formed on the front end portion of the mounting bolt 3 so as not to be relatively rotatable. It has a joint part 20b and a pair of rotation operation parts 20c formed so as to protrude laterally at the base end part of the main body part 20a.
[0028]
  Next, the attachment method with respect to the wall surface structural member H of the article attachment tool M is demonstrated, referring FIGS. 23-32. In addition, in the figure, H2 is a wall body member of a building, and a wall surface constituting member H that is also an interior material is installed at a small interval on the surface side of the wall body member H2. First, in a state in which the two anchor pieces 1 and 2 are overlapped with each other and the surface side member 4 and the lock nut 5 are attached to the attachment bolt 3, as shown in FIGS. Insert into the opening 10 from the side of 1a, 2a. At this time, the lock nut 5, that is, the surface-side member 4 is positioned on the tip side (surface side) of the mounting bolt 3 so as not to obstruct the insertion of the anchor pieces 1 and 2 into the opening 10. deep.
[0029]
  As shown in FIGS. 25 and 26, the two anchor pieces 1 and 2 are further inserted deeply into the opening 10 so as to be twisted. At the time of this insertion, insertion of the anchor pieces 1 and 2 is possible even if the distance between the wall main body member H2 and the wall surface constituting member H is small as compared with the case where the anchor pieces are straight. Thus, the insertion of the two anchor pieces 1 and 2 into the opening 10 proceeds, and eventually the anchor pieces 1 and 2 completely pass through the opening 10 as shown in FIGS. 27 and 28. Become. Even if the hand is released from the article attachment M, the front surface side member 4 is brought into contact with (locked to) the outer peripheral edge of the opening 10 and the article attachment M falls on the back side of the wall surface constituting member H. There will be no such situation. In a free state in which the hand is released from the article attachment M, the two anchor pieces 1 and 2 are in a posture in which the tip portions 1a and 2a face downward due to gravity.
[0030]
  From the posture state in which the distal end portions 1a, 2a of the two anchor pieces 1, 2 are directed downward, as shown in FIGS. 3b, the rotating jig 20, that is, the mounting bolt 3 and the first anchor piece 1 are rotated in a predetermined direction, and the first anchor piece 1 extends upward in the opposite direction to the second anchor piece 2. And In this state, after removing the rotating jig 20 from the mounting bolt 3, the lock nut 5 is tightened, so that the first anchor piece 1 extends upward as shown in FIGS. In a state where the piece 2 extends downward, the wall constituent members H are firmly held between the anchor pieces 1 and 2 and the surface side member 4 (installation of the mounting bolt 3 to the wall constituent member H is completed). . 31 and 32 correspond to FIGS. 1 and 2.
[0031]
  In the state in which the attachment fixture M is attached to the wall surface component H, an article such as a handrail is attached on the surface side of the wall surface configuration member H using the attachment bolt 3 (attachment of the article using the attachment bolt 3) An example will be described later). In this article attachment state, the load from the attached article is firmly received by the wall surface constituting member H by the anchor pieces 1 and 2 and the surface side member 4.
[0032]
  When the load from the article, that is, the load from the mounting bolt 3 is supported, the anchor pieces 1 and 2 support the load so that they are pressed against the back surface side of the wall surface component H. In particular, with respect to a load in a direction perpendicular to the axis of the mounting bolt 3, the first anchor piece 1 is supported by being strongly pressed against the back surface side of the wall surface component H by a moment due to a downward load. 2 is supported by the bottom of the inner peripheral surface of the opening 10 through the base end 2a of the anchor piece 2, and is also supported by the bottom of the inner peripheral surface of the opening 10 through the side wall 4b of the surface side member 4. . Conversely, in the case of an upward load, the second anchor piece 2 is supported by being strongly pressed against the back surface side of the wall surface component H by a moment due to the upward load, and the side wall portion 4b of the front surface side member 4 is supported. It is supported also on the inner peripheral surface upper part of the opening part 10 also through. In the case of a load in the lateral direction, the tip end portion 1a or 2a extending in the lateral direction of the anchor pieces 1 and 2 is supported by receiving a moment from the lateral direction and being strongly pressed against the back surface side of the wall surface component H. It is supported on the inner peripheral surface side portion of the opening 10 via the side wall portion 4 b of the side member 4. In this way, by setting the two anchor pieces 1 and 2 extending in opposite directions to each other and by bending the tip portions 1a and 2a of the anchor pieces 1 and 2 in the lateral direction, A load can be supported over a wide range in a direction orthogonal to the axis (the directions in which the tip portions 1a and 2a extend are substantially opposite to each other).
[0033]
  Since the tip portions 1a and 2a of the two anchor pieces 1 and 2 are wide, the load bearing ability is high. Further, the intermediate portions 1c and 2c of the anchor pieces 1 and 2 have a gap with the wall surface component H, that is, the tip portions 1a and 2a of the anchor pieces 1 and 2 are surely brought into contact with the wall surface component H. Therefore, it is possible to reliably obtain a large load bearing using the wide end portions 1a and 2a.
[0034]
  FIG. 33 shows a case where there is a pillar 33 extending in the vertical direction in the vicinity of the opening 10 in the space between the wall main body member H2 and the wall surface constituting member H. In this case, the second anchor piece 2 extends downward along the side surface of the spacer column 30, and the first anchor piece 1 is rotated clockwise in the drawing to be in contact with the side surface of the spacer column 30 and ensure a state of extending upward. Is done. That is, also in this case, the load can be supported over a wide range in the direction orthogonal to the axis of the mounting bolt 3.
[0035]
  34 shows a column 34 extending in the vertical direction in the space between the wall main body member H2 and the wall surface constituting member H, in the vicinity of the opening 10, in the position opposite to the case of FIG. Is present. Also in this case, the load can be supported over a wide range in the direction orthogonal to the axis of the mounting bolt 3 as in the case of FIG. In addition, the rotation direction of the 1st anchor piece 1 is made into the reverse direction from the case of FIG.
[0036]
  FIG. 35 shows a case where a spacer 35 </ b> A extending in the vertical direction in the vicinity of the opening 10 and a spacer 35 </ b> B extending in the horizontal direction above the opening 10 exist in the space between the wall body member H <b> 2 and the wall surface component H. Is shown. In this case, the second anchor piece 2 extends downward along the side surface of the intermediate column 35A, and the first anchor piece 1 extends laterally so as to contact the lower side surface of the intermediate column 35B. In this case as well, the load can be supported over a wide range as much as possible in the direction orthogonal to the axis of the mounting bolt 3 although the anchor pieces 1 and 2 are not substantially extended in the opposite direction.
[0037]
  FIG. 36 illustrates a case where a space 36 </ b> A extending in the vertical direction in the vicinity of the opening 10 and a space 36 </ b> B extending in the horizontal direction below the opening 10 exist in the space between the wall body member H <b> 2 and the wall surface component H. Is shown. In this case, the second anchor piece 2 extends in the lateral direction so as to abut on the upper side surface of the intermediate column 36A, and the first anchor piece 1 extends upward so as to abut on the side surface of the intermediate column 36B. In this case as well, the load can be supported over a wide range as much as possible in the direction orthogonal to the axis of the mounting bolt 3 although the anchor pieces 1 and 2 are not substantially extended in the opposite direction.
[0038]
  37 to 39 show a second embodiment of the present invention, and the same reference numerals are given to the components corresponding to the components of the embodiment. In the present embodiment, the first anchor piece 1B (corresponding to the anchor piece 1) and the second anchor piece 2B (corresponding to the anchor piece 2) are substantially straight without being curved, and the first implementation. It is supposed to be shorter than the case of form. FIG. 40 shows an example in which a handrail as an article is attached using the mounting bolt 3.
[0039]
  In FIG. 40, a fixed side member 42 is fitted to the mounting bolt 3 via a spacer 41, and this fixed side member 42 is firmly fixed to the mounting bolt 3 by a lock nut 44 via a washer 43. A male screw is formed on the outer peripheral surface of the stationary member 42. On the other hand, a flange portion 51 is formed at the attachment end portion of the handrail T, and a lock member 52 is rotatably fitted to the flange portion 51 portion. The lock member 52 is prevented from coming off by the flange portion 51, and an internal thread is formed on the inner peripheral surface thereof. By screwing the locking member 52 to the fixing member 42 fixed to the mounting bolt 3, the flange portion 51 is pressure-bonded to the fixing-side member 42 and is fixed. In addition, the attachment methods, such as a handrail using the attachment bolt 3, can be selected suitably.
[0040]
  41 and 42 show a third embodiment of the present invention. The anchor pieces 1B and 2B are the same as those in FIGS. 37 to 40, and the surface side member 4B is formed by casting. That is, in particular, the substrate portion 4a and the side wall portion 4b of the front surface side member 4B are thickened, and the concave portion 4e for accommodating the lock nut 5c is formed on the front surface side, so that the lock nut 5 is the wall surface component H. It is made not to protrude to the surface side. In this example, the board part 4a and the side wall part 4b through which the mounting bolt 3 passes can be made thicker in the surface side member 4B, and the rigidity of the surface side member 4B itself is sufficiently increased to enhance the load bearing capacity. Is preferable. Further, the mounting bolt 3 can be supported over a wide range in the axial direction by the surface side member 4B.
[0041]
  43 and 44 show a fourth embodiment of the present invention, and show a case where the anchor piece is only one anchor piece 1D corresponding to the first anchor piece 1. However, since the base end 1 a is fitted into the opening 10, the base end 1 a is offset so as to slightly protrude toward the tip end side of the mounting bolt 3.
[0042]
  Although the embodiment has been described above, the article is not limited to the handrail, and may be various articles that are required to be attached to the wall surface constituting member H. The predetermined position corresponding to the direction in which the first anchor piece 1 extends in the tip portion of the mounting bolt 3 so that the rotational posture position of the first anchor piece 1 (1B) can be more easily confirmed from the surface side of the wall surface component H. It is preferable to form an index at one position in the circumferential direction (for example, formation of a concave portion or coloring). The object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
