Description

  The present invention is a gap smaller than the size of the standard floor board (hereinafter referred to as the standard floor board) formed between the end of the standard floor board that is laid down on the foundation floor surface via the standard support and the partition wall that partitions the room to construct a double floor. The present invention relates to a border strut for a double floor having a structure for preventing the border floor board from rising, among the border struts supporting the side of the border floor board that fills the border gap).

  When filling a border gap generated when a double floor is constructed, a wood-based dedicated floor panel that can be easily cut according to the size of the border gap may be cut and used. However, when a wood-based exclusive floor panel is used, there is a problem that the strength is lower than that of a normal floor panel and the warp is likely to occur. For this reason, a normal floor panel with high strength performance may be cut and used as a border floor board. As a method for preventing the floating by fixing the border floor board to the border post, a method of driving a screw from above the border floor board toward the border post is used. This method has poor workability because it is necessary to open a pilot hole, and has poor maintenance because it is troublesome to attach and detach the border floor board.

  Therefore, the conventional border struts are, for example, a leg portion (base member) fixed on the floor surface (foundation floor) and a leg top portion as seen in a border panel support (border strut) of Patent Document 1. It is composed of a base plate (support member) that is attached to the base plate so as to be adjustable in height and supports the end of the border panel (border floor plate). The base plate is erected along the side of the wall and the piece is erected. At the same time, the presser claw with a gap into which the bottom panel of the border panel can be inserted is raised and bent inward from the piece, and the bottom panel of the border panel is pressed with this presser claw. And maintainability are improved.

Japanese Patent Laid-Open No. 2001-173212 (refer to pages 3 to 5 and FIG. 2)

  However, in the type of support (see Patent Document 1 FIG. 4 and FIG. 6) in which a nut directly attached to the lower surface of the base plate is screwed into the bolt column of the leg together with the base plate, the base plate rotates (height adjustment). Therefore, depending on the height of the support, the presser claw does not face the border panel and the bottom plate cannot be inserted. Further, when the base plate is rotated to make the direction of the holding claws coincide with each other, the height of the support column is changed, and there is a problem that rattling occurs in the border panel. Furthermore, there is a problem that the base plate cannot be rotated and the height cannot be adjusted while the bottom plate of the border panel is still inserted in the gap between the pressing claws. These problems are not limited to the type of support shown in FIGS. 4 and 6, for example, a type of support in which a bolt is provided downward on the bottom plate and the bolt is screwed into a nut provided on the leg side. Also applies.

  To solve these problems, the cylindrical support attached to the lower surface of the base plate is fitted into the bolt support provided on the leg, and this is supported by the nut screwed to the bolt support. It is conceivable to employ a type of support that fixes the body to a bolt post with a set screw of a push screw type (see Patent Document 1 FIGS. 1 to 3). However, in the case of this type of support, the base plate is likely to wobble or tilt due to the gap between the bolt support and the cylindrical support. Moreover, since these problems become more conspicuous as the length of the cylindrical support becomes shorter, the above-mentioned type of support still has a problem that it cannot cope with a support having a low height. Therefore, even if it is a border strut that adjusts the height by screwing the base plate directly into the leg part, we studied to develop a border strut that can change the direction of the holding claws regardless of the height adjustment.

What has been developed as a result of the study includes a base member that is installed on the foundation floor along the side of the wall, and a support member that is screwed into the base member and supports the side of the border floor plate so that the height can be adjusted. A double-floor border strut with a support claw that is inserted into a locking gap provided at the side of the floor of the floor and prevents the border floor from being lifted. a resin border mounting body being, the pressing pawl horizontal times the upper surface of the support member configured rotating member and a integrally molded border mounting corotation freely attached is metal fixture mounting body It is a border strut for a double floor that can be moved freely. The border strut of the present invention can change the direction of the presser claw irrespective of the height adjustment by providing the presser claw on the rotary member that is horizontally rotatable independently of the support member.

  Specifically, the support member is formed with a rotation guide protrusion that guides the rotation of the rotation member in a circumferential shape, and the rotation member has a rotation contact portion that is in sliding contact with the rotation guide protrusion. The structure in which is formed can be mentioned. More specifically, a horizontal support table on which the rotation member is placed is formed in a circular shape on the support member, and the periphery of the support table is a rotation guide protrusion, while the rotation member has a rotation A rotation contact portion is formed on the entire circumference or a plurality of positions adjacent to the guide ridge, and a latching groove for inserting the rotation guide ridge of the support table and sandwiching it up and down is located below the holding claw of the rotation member. The provided structure can be mentioned.

  The border post has a structure in which the rotating member is integrally provided with the pressing claw. However, the pressing claw may be separated from the rotating member, and another member provided with the pressing claw may be attached to the rotating member. . Specifically, the rotation member is attached to the support member and a border placement body made of resin, which is rotatably mounted in a horizontal plane, and a border placement body in which a pressing claw is integrally formed. It may be a double-floor border post composed of a metal fixture. Thereby, the structure which satisfy | fills the request | requirement calculated | required by each part of a rotation member, ie, the presser nail | claw by which rigidity is calculated | required, can be made from metal, making the border mounting body into resin.

  In this case, like the border strut, the support member is formed with a rotation guide ridge that circumferentially guides the rotation of the rotation member, and the border mounting body is in sliding contact with the rotation guide ridge. It is good to set it as the structure in which the rotation contact part was formed. More specifically, on the support member, a horizontal support table on which the border mounting body is placed is formed in a circular shape, and the peripheral edge of the support table is a rotation guide ridge, A rotation contact portion is formed on the entire circumference or at a plurality of positions adjacent to the rotation guide ridge, and the rotation guide protrusion of the support table is inserted into the lower position of the holding claw of the rotation member, and hooked up and down. A structure provided with a groove is preferable. Furthermore, the border mounting body may be configured to have a buffer portion interposed between the latching groove and the rotation guide protrusion.

  According to the present invention, the direction of the presser claw can be changed regardless of the height adjustment, and the border floor plate is formed by inserting the presser claw into the engaging gap provided on the side of the border floor plate and engaging it. Fixing work becomes easy. Specifically, by making the rotating member rotatable with respect to the support member, it becomes possible to freely change the direction of the pressing claw regardless of the height of the support member, and the occurrence of rattling of the border floor board is generated. The effect which can suppress or prevent is acquired. Further, even when the border floor board is placed and fixed, the height can be adjusted by rotating only the support member regardless of the rotating member. In addition, by configuring the rotating member from the resin border mounting body and the metal fixture, it is possible to easily satisfy the requirements required for each part of the rotating member. It becomes possible to provide a border strut that can stably support.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. 1 is a perspective view of a double floor system using the border strut 1 of the present invention, FIG. 2 is a partially exploded perspective view showing the relationship between the standard strut 7 and the standard floor board 6, and FIG. 4 is a partially exploded perspective view showing the relationship, FIG. 4 is a partially exploded perspective view of the border post 1, FIG. 5 is an enlarged plan view of the border part of the double floor system, FIG. 6 is an AA enlarged sectional view in FIG. 5 is an enlarged sectional view taken along the line BB in FIG. 5, FIG. 8 is an enlarged sectional view corresponding to the line BB in FIG. 5 showing the construction of the border floor board 5, FIG. 9 is a left side view of FIG. 5 is an enlarged cross-sectional view corresponding to BB in FIG. 5, FIG. 11 is an enlarged cross-sectional view taken along CC in FIG. 5, and FIG. 12 is a plan view of the border mounting body 3 constituting the rotating member. FIG. 13 is a sectional view taken along the line DD in FIG.

  As can be seen in FIG. 1, the border strut 1 of the present invention supports the corners close to the wall 8 of the border floor 5 that fills the border gap, and therefore along the wall 8 on the foundation floor 9 in the border gap. And are fixed and fixed at regular intervals. The border floor board 5 is obtained by cutting and reducing one side of the standard floor board 6 in accordance with the width of the border gap, and is arranged in such a direction that the cut side (hereinafter referred to as a cut side) runs along the wall 8 side. The Accordingly, the opposite corner of the border floor board 5 has the same shape as the standard floor board 6 and is supported by the standard support column 7 that supports the standard floor board 6. The standard struts 7 are installed on the foundation floor 9 other than the border gap by bonding and fixing at regular intervals in the vertical and horizontal directions, and the standard floor boards 6 are laid and placed on the four corners.

  As shown in FIG. 2, the standard support column 7 supports one corner of the standard floor plate 6 so that the height can be adjusted, and a base member 71 bonded and fixed on the foundation floor 9 and screwed into the base member 71 to form a standard floor plate. 6 is mounted on the upper surface of the support member 72 so that the height of the four corners of the support member 72 can be adjusted. The standard support plate 75 made of resin for restricting the position of the standard floor plate 6 and the base member 71 And a panel presser 74 that presses and fixes 6 to the standard mounting body 75. At the center of the support member 72, a support nut 721 that is screwed to a screw rod 711 standing at the center of the base member 71 is fixed, and the height of the screw is adjusted by adjusting the screwing position of the support nut 721 with respect to the screw rod 711. Adjustable configuration. The panel retainer 74 also has a function of tightening and fixing the position to the upper surface side of the support nut 721 after the height of the support member 72 is adjusted.

  The standard floor board 6 is a standard member having a substantially square shape in a plan view with a side of about 500 mm. As shown in FIG. 2, the steel plate surface plate 61 and the back plate 62 are integrated by caulking connection with a peripheral flange 64 obtained by horizontally bending the upper edge of the outer peripheral wall 63 of the back plate 62. The interior surrounded by the front plate 61 and the back plate 62 is provided with a core member 65 made of a wooden board such as a particle board, and the core member 65, the front plate 61 and the back plate 62 are bonded and fixed. , Increase the structural strength. A corner portion of the standard floor board 6 is cut out in a quadrant in a plan view, and a low step portion 66 is provided along the periphery of the cutout. As a result, the four corners of the four standard floor boards 6 are brought into contact with each other, the panel presser 74 is inserted into a hole formed surrounded by each low step portion 66, and screwed into the tip of the screw rod 711 of the standard support 7 to thereby form a panel. Each low step portion 66 is pressed by the foot of the presser 74, and the four standard floor boards 6 are fixed to the standard support column 7.

  The border floor board 5 has a structure in which one side of the standard floor board 6 is cut in accordance with the size of the border gap, and is bridged between the border pillar 1 and the standard pillar 7 so that the space between the standard floor board 6 and the wall 8 is increased. The gap is closed (see FIGS. 1 and 5). As shown in FIG. 3, locking gaps 57 into which the pressing claws 41 of the border column 1 are inserted are provided at both ends of the cut side of the border floor board 5. The locking gap 57 of this example is formed as a space for inserting the presser claw 41 between the core material 55 and the outer peripheral wall 53, and as shown in FIG. By pressing down the back plate 52 of 5, the border floor plate 5 is restricted from being displaced upward.

  In the standard floor board 6 of this example, the outer dimension of the core member 65 is set to be small with respect to the position of the outer peripheral wall 63, so that a space serving as the locking gap 57 is always formed on the entire length of the four sides (entire circumference). The structure is made. Therefore, no matter where the standard floor board 6 is cut in accordance with the width of the border gap, the locking gap 57 can be formed at both ends of the cut side of the border floor board 5. Certainly, even if it is a floor board that adopts a structure filled with the core material 65 up to the outer peripheral wall 63, the locking gap 57 can be formed by drilling the core material with a drill etc. after cutting. Since noise and cutting waste are generated at the site, it is not preferable in the working environment. The standard floor board 6 of this example is excellent in that the work on the construction site is not necessary.

  As the standard floor board 6, for example, a hollow structure in which the inner space between the front board 61 and the rear board 62 is not filled with the core material 65 is also common. Therefore, the standard floor board 6 may have a hollow structure, and the border floor board 5 may have a solid structure including the core material 55 as in this example. When the standard floor board 6 having a hollow structure is cut to form the border floor board 5, a locking gap can appear as in the present example. However, since the strength of the cut side is significantly reduced, it is not preferable as the border floor board 5. Since the standard floor board 6 of this example has the core material 65 in the internal space, the strength reduction of the cut side is extremely small, and the preferred floor board 5 can be obtained. In addition, as a structure for causing the locking gap to appear, a structure in which an extruded shape member having a cross-sectional shape that becomes the locking gap is fixed to the outer periphery of the floor board can be exemplified.

  As shown in FIG. 4, the border support 1 is screwed onto a base member 11 that is adhered and fixed on the foundation floor 9 in the border gap along the side of the wall so that the height can be freely adjusted. The rotating member 2 provided with 41 and 41 is attached to the upper surface of the support member 12 so as to be horizontally rotatable. The base member 11 and the support member 12 in the border column 1 are the same as the base member 11 and the support member 12 in the standard column 1, and cost reduction is achieved by common use of the members. The rotating member 2 of this example has a configuration in which a metal fixture 4 in which a pressing claw 41 is integrally formed is attached to a resin-made border mounting body 3. The border mounting body 3 is mounted so as to be horizontally rotatable with respect to the support member 12, and the orientation of the pressing claw 41 formed on the fixture 4 is independent of the rotation of the support member 12 accompanying the height adjustment. It can be changed freely.

  The base member 11 is a member in which a screw rod 111 made of caulking bolts is erected at the center of a metal plate-like body having a square shape in plan view, and the support member 12 is a metal cup-shaped body having a circular shape in plan view. A support nut 121 made of a caulking nut is fixed to the center of the bottom of the base plate. By changing the screwing position of the support nut 121 with respect to the screw rod 111, the height of the support member 12 can be adjusted.

  The support member 12 is formed with a horizontal bowl-shaped support table 122 on the outer peripheral edge, and the outer peripheral end surface thereof is a rotation guide ridge 123 that guides the horizontal rotation of the fixture 4. A concave portion 124 is formed in an inner portion surrounded by the support table 122, and a support nut 121 is fixed to the bottom surface thereof. In the recess 124, the tip end portion of the screw rod 111 protruding upward from the support nut 121 is accommodated. The screw rod 111 and the support nut 121 may be reversed in the vertical relationship as long as a predetermined screwing amount (height adjustment allowance) can be secured. For example, a high nut is erected on the base member 11 and the support member 12 A structure in which a caulking bolt is suspended may be used. A locking nut 13 is screwed onto the threaded rod 111, and after the height of the support member 12 is adjusted, the position is fixed by tightening to the lower surface side of the support nut 121.

  The border mounting body 3 is a resin member having a circular shape in plan view, and is mounted on the support table 122 of the support member 12 so as to be horizontally rotatable. As shown in FIG. 11, the border mounting body 3 slides the inner peripheral surface of the rotation abutting portion 31 that hangs down on the entire outer periphery to the rotation guide ridge 123 to rotate the fixture 4 horizontally. It functions as a guide when moving. Since the border floor board 5 supported via the border mounting body 3 does not directly touch the metal support member 12, sound generation is prevented even if there is slight backlash. Furthermore, a locking projection 32 is formed on the inner peripheral surface of the rotating pad 31 to lock the back surface of the periphery of the support table 122 so that the border mounting body 3 is not easily detached from the support table 122. I have to. The rotation contact portion 31 also has a function of making it difficult for the border mounting body 3 to come off from the support table 122, and is preferably provided over the entire circumference as in this example. It is sufficient that the locking protrusions 32 are provided at about four locations (see FIG. 12) at intervals of 90 degrees.

  The rotation guide ridge 123 may be provided on the inner periphery of the support table 122 as well as on the outer periphery of the support table 122 as in this example. Specifically, the support table 122 is folded inward, or a separate ring-shaped plate is fixed to the edge of the recess 124 so that the inner peripheral edge of the support table 122 protrudes into the recess 124 and rotates. The structure which makes the guide ridge 123 can be illustrated. In this case, the rotation abutment portion 31 is provided inside the rotation guide ridge 123, and the outer peripheral surface is slidably contacted with the rotation guide ridge 123 so as to act as a guide when the rotation member 2 is horizontally rotated. be able to. Further, the rotation abutment portion 31 is formed with an engagement protrusion 32 that engages with the back surface side of the rotation guide ridge 123 on the outer peripheral surface so that the border mounting body 3 is not easily detached from the support table 122. You can also.

  On the upper surface of the border mounting body 3, a mounting portion 33 for inserting and mounting the fixture 4 from the lateral direction extends from the outer edge in the diameter direction. The attachment portion 33 includes a side wall 331 that restricts the left and right positions of the fixture 4 and an upper wall 332 that restricts the upper position. The side wall 331 is formed with a retaining protrusion 333 that is engaged with an engaging hole 421 provided on the side surface of the fixture 4. The attachment portion 33 opens an insertion port 34 for inserting the fixture 4 from the lateral direction in the vicinity of the outer edge of the border mounting body 3. At the bottom of the side wall 331 in the vicinity of the insertion port 34, a first buffer part 35 having a L-shaped cross section and a second buffer part 36 having a band shape are formed in order from the outside to connect the side walls 331, 331. Tongue-shaped third buffer portions 37 and 37 are provided to protrude from the left and right side walls 331 and 331 at the same height as the second buffer portion 36 (see FIGS. 6 and 12).

  As shown in FIG. 13, the first buffer portion 35 has a vertical wall portion with an L-shaped cross section that abuts on the rotation guide ridge 123 at the tip of the support table 122, and a horizontal wall portion that abuts the back surface of the support table 122. . The second buffer portion 36 is located on the support table 122, and the third buffer portion 37 is disposed above the recess 124. The upper surface of the border mounting body 3 is formed on the flat low surface portions 38 and 38 with the mounting portion 33 on the half side on the side where the insertion port 34 is provided, and the remaining half side is formed on the lower surface portion 38 with the mounting portion 33 in between. It is formed in flat high surface portions 39, 39 which are raised one step. The border floor board 5 is placed on the high surface portion 39 on the side away from the press claws 41, 41.

  As shown in FIG. 4, the fixture 4 includes a main body portion 42 in which long side portions on both sides are bent downward at a right angle from the upper surface of the rectangle in plan view to form a side surface, and a top end portion of the upper surface of the main body portion 42 is downward. The wall abutting portion 43 is formed by being bent at a right angle, and left and right holding claws 41, 41 are formed by bending the left and right ends of the wall abutting portion 43 at a right angle toward the main body portion 42 side. The fixing device 4 is attached to the attachment portion 33 by horizontally inserting the rear side of the main body portion 42 (the side where the pressing claws 41 and 41 are not formed) into the insertion port 34 of the border mounting body 3. At this time, the border mounting body 3 may be previously attached to the support member 12 alone, or the rotating member 2 configured by attaching the fixture 4 to the border mounting body 3 in advance is used as the support member 12. You may attach to.

  On the main body portion 42 of the fixture 4, an L-shaped flange 45 is projected downward from the lower end of the side surface of the main body portion 42, thereby extending downward toward the front end (outside) below the pressing claws 41 on both sides. Stop grooves 44, 44 are formed horizontally. The retaining grooves 44, 44 allow the first buffer portion 35 and the second buffer portion 36 of the border mounting body 3 and the support table 122 to be inserted integrally, and the fixture 4 (pressing claws 41, 41) Make sure that it does not rise. Further, the locking projections 32 and 32 are inserted into the locking holes 421 and 421 provided on both side surfaces of the main body portion 42 so that the fixture 4 does not come out of the mounting portion 33. The presser claw 41 is inserted into a locking gap 57 provided between the outer peripheral wall 53 of the border floor board 5 and the core member 55. In order to facilitate the insertion, the corner portion on the lower side of the tip is chamfered and released. 411 is provided.

  It is desirable that the fixture 4 can be mounted on the support member 12 without rattling or shading. Therefore, in this example, as shown in FIG. 13, the second buffer portion 36 is interposed between the upper surface of the support table 122 and the lower end of the side surface of the main body portion 42 of the fixture 4, and the rotation guide ridge 123. A first buffer portion 35 is interposed between the side surface and the lower surface of the first and second retaining grooves 44 and 44. Thereby, contact (metal touch) between the support table 122 and the fixture 4 can be prevented. In addition, the fixture 4 stabilizes the mounting state of the support member 12 by press-fitting the first buffer portion 35 into the groove width (vertical width) of the latching groove 44. In addition, the fixture 4 supports the lower end of the rear side surface of the main body portion 42 on the third buffer portion 37 to enhance the stability of the mounting state with respect to the support member 12.

  As shown in FIG. 3, the gap member 58 is a foamed resin tape that is attached to the cut side of the border floor board 5, and the cutting waste of the core material 55 and the front and back plates 14, 15 falls down by covering the cut side. In addition to preventing this, as seen in FIG. 5, it has a role of closing a gap formed between the wall 8 and the border floor board 5. In the relationship between the border floor board 5 and the fixture 4 in this example, even if the holding claw 41 is completely inserted into the locking gap 57 of the border floor board 5, A gap corresponding to the plate thickness (around 2 mm) of the wall abutting portion 43 provided on the fixture 4 is generated. In addition, a gap of about 1 mm is secured between the wall abutment 43 and the wall 8 for the purpose of preventing noise generation, so a total of about 3 mm of gap occurs over the entire area between the adjacent border struts 1 and 1. To do. The gap member 58 also has a function of closing the gap, and has an effect of improving the finish of the border portion.

  Here, if the portion of the outer peripheral wall 53 is notched so that the thickness of the wall abutting portion 43 does not protrude outward from the border floor plate 5, it occurs between the cut edge of the border floor plate 5 and the wall 8. The gap to be made can be reduced. However, such a notch processing increases the number of work steps at the construction site, and the straightness of the wall 8 and the straightness of the cut side of the border floor board 5 vary considerably. Therefore, the wall 8 and the border floor board 5 There is a gap between the two. For this reason, in this example, the gap is positively provided and is closed by the gap member 58 having an appropriate thickness.

  Hereinafter, a procedure for laying the border floor plate 5 between the border support column 1 and the standard support column 7 which are bonded and fixed to the foundation floor 9 in advance will be described. First, the cut side of the border floor board 5 is inclined downward toward the wall 8 side, and the position of the locking gap 57 is made to approach the pressing claw 41 (see FIG. 8). At this time, since the locking gap 57 is hidden from the operator and cannot be seen, the positions of the pressing claw 41 and the locking gap 57 may not be aligned. Therefore, in order to match the left and right positions of the locking gap 57 and the pressing claw 41, in this example, the side wall 331 of the mounting portion 33 of the border mounting body 3 is used as an insertion positioning portion, and the outer peripheral wall 53 of the border floor board 5 is placed on the side wall 331. It is made to approach, making it slide while applying (refer FIG. 9). In addition, as shown in FIG. 8, when the lower end of the cut side of the border floor board 5 is placed on the lower surface portion 38 and slid, the vertical position can be adjusted, and the weight of the border floor board 5 can be reduced and work can be performed. There is also an advantage that makes it easier.

  Thus, when the border floor plate 5 is brought closer to the fixture 4, the holding claw 41 is provided with the relief 411, so that the alignment function by sliding the outer wall 53 of the border floor plate 5 against the side wall 331 is combined with the alignment function. Thus, the pressing claw 41 can be easily inserted into the locking gap 57. Since it is unlikely that the holding claw 41 will come off from the locking gap 57 once inserted, the end surface of the cut side should be in contact with the back surface of the wall abutting portion 43 and slide until it can no longer be pushed. (See Figure 10). When the insertion of the presser pawl 41 is completed, the corner can be placed on the standard support column 7 (standard mounting body 75) by lowering the side opposite to the cut side of the border floor board 5.

  At this time, as shown in FIG. 7, since the lower end position of the pressing claw 41 is set to be substantially the same as the height of the high surface portion 39 on which the border floor plate 5 is placed, the border floor plate 5 The cut edge side can be lowered by the thickness of 52. Some clearance exists between the members, and slight deformation occurs in each member. Therefore, the border floor board 5 is in a substantially horizontal state by its own weight. Thereby, the border floor board 5 and the press nail | claw 41 can be engaged in the state which absorbed the backlash resulting from the manufacture error of each member.

  Since the border floor board 5 of this example is constructed by cutting the standard floor board 6, naturally, a low step portion 56 is provided at the corner opposite to the cut side. Therefore, if the panel retainer 74 is inserted into a hole formed by abutting the corners of the two border floor plates 5 and the corners of the two standard floor plates 6, and tightened to the screw rods 711 to be fixed, A series of laying operations is completed. In this way, the border floor board 5 is fixed in the four corners to the standard support column 7 or the border support column 1 in a state where the rattling is almost completely absorbed, and the floating is strongly prevented.

  The high surface portion 39 is preferably provided at a position away from the presser claw 41. The low surface portion 38 is a surface having a relatively low height that is inevitably formed as a result of the provision of the high surface portion 39, but the vertical position of the border floor plate 5 with respect to the pressing claw 41 that is inclined when the pressing claw 41 is inserted is changed. In this way, it is possible to freely perform the effect of facilitating the insertion operation of the pressing claw 41 into the locking gap 57.

  14 is a partially exploded perspective view of the border strut 1 using another rotating member 2, FIG. 15 is a partially enlarged plan view showing the relationship between the border strut 1 and the border floor board 5, and FIG. It is -E sectional drawing. The border column 1 of this example is different from the above example (see FIGS. 1 to 13) only in the structure of the rotating member 2, and the base member 11 and the support member 12 have the same structure, and thus description thereof is omitted. . The rotating member 2 of another example is not constituted by two parts of the border placing body 3 and the fixture 4, but is constituted by integral molding of resin. Specifically, the entire rotating member 2 of another example is basically a disk corresponding to the border mounting body 3, and a positioning block 22 protrudes from the center line on the upper surface side of the disk, and both left and right sides from the tip thereof. The presser claws 21 and 21 are folded inward and are integrally provided.

  The front end surface of the positioning block 22 is formed in a wall abutment portion 27, and a pair of pressing claws 21 and 21 extending inward in the radial direction by folding inward from both sides of the wall abutment portion 27 are formed. A relief 211 is formed at the tip of the pressing claw 21 as in the above example. Under the presser claws 21, 21, latching grooves 28, 28 extending horizontally toward the tip (outside) are horizontally formed by projecting an L-shaped flange 29 downward from the lower end of the side wall 221. . The left and right side walls 221 of the positioning block 22 have an insertion positioning function so that the left and right positions of the locking gap 57 and the pressing claw 21 can be aligned by contacting the outer peripheral wall 53 of the border floor board 5. ing. Since these holding claws 21 and the side walls 221 of the positioning block 22 are applied with a relatively large force against the floating of the border floor board 5, the rigidity is increased by providing ribs or increasing the thickness. It is preferable to keep it.

  On the upper surface of the disk on both sides of the positioning block 22, as in the above example, the half near the holding claw 21 is formed as a relatively low flat surface portion 25, 25 and the other half is a relatively high flat height. It is formed as a surface portion 26. On the outer peripheral edge of the disk, there are four pivot contact portions 23 formed at equal intervals, and locking projections 24 project inwardly at the tips of the respective pivot contact portions 23. As described above, according to the integrally formed rotating member 2, the retaining protrusion related to the mounting portion 33 of the border mounting body 3, which is necessary for mounting the fixture 4, compared to the above-described example of two members. 333, the insertion port 34, the first buffer 35, the second buffer 36 and the third buffer 37 are not required, and the fixture 4 is not required to have the main body 42 or the locking hole 421. There is an advantage that assembly work is also unnecessary.
