Embodiments of the present invention will be described below with reference to the drawings shown in FIGS. 1 to 7.

First, the installation structure 10 to which the main strut device T is attached will be described with reference to FIG. 7. The installation structure 10 is a shelf device installed on the floor 3, as shown in FIG. This shelf device is a frame-shaped shelf in which a pillar portion 11 perpendicular to the floor surface and a horizontal bridge portion 12 parallel to the floor surface are combined and joined. Each of the pillar portion 11 and the horizontal portion 12 is formed of a columnar member as shown in the enlarged cross-sectional view of FIG. 7B and the enlarged partial plan view of FIG. 7C.

The columnar members arranged in one direction among the horizontal bridges 12 arranged vertically and horizontally on the upper surface are the rails 20 to which the main strut device T is attached. The horizontal portion 12 arranged in the other direction is a short rail 25, and the strut device T is not attached in this embodiment.

In this columnar material, the prismatic material used as the main body 21 may be made of a wood material, a synthetic resin material, a metal material, or the like, and the four sides around the prismatic material are arranged along the longitudinal direction of the prismatic material. A rail groove 22 is formed. If the main body 21 is made of a synthetic resin material or a metal material, it may be a hollow material. Further, a thin plate made of a metal material, a synthetic resin material, or the like is fixed to the outer surface of the main body 21 so that the groove opening 23 of the rail groove 22 is opened substantially at the center in the width direction. This thin plate constitutes the retaining piece 24.

In order to form the installed structure 10, the columnar members may be connected to each other using the rail groove 22 and a connecting tool (not shown). Further, in the installed structure 10 shown in FIG. 7A, the shelf plate 13 is provided in the middle of the height direction. The shelf plate 13 may also be fixed using a connecting tool (not shown) for the rail groove 22.

The installation structure 10 to which the strut device T is attached is not limited to the frame-shaped shelf described above. Further, the rail 20 does not have to be configured by the horizontal bridge portion 12 which is a component of the installation structure 10, and may be another rail added to the upper surface. Further, for example, rails may be attached to the upper surface of a closet or a cupboard so as to face each other, substantially parallel to each other.

The main strut device T includes, for example, the above-described installation structure 10 installed on the floor 3, and a ceiling base 1 (field edge) (see FIG. 3) covered with a ceiling 2 (see FIG. 3) from below. It is a device that is fixed and attached so as to be interposed between the two.

Next, the mounting structure of the strut device will be described with reference to FIGS. 1 and 2. In FIG. 1, the installed structure 10 is simply shown in a rectangular parallelepiped shape, the rails 20 on the upper surface are shown by thick lines, the bracing apparatus T is schematically shown, and the field edge 1 is shown by chain double-dashed lines. Further, in FIG. 2, the bracing device T (the plate-shaped member 30 and the rod-shaped member 40) is shown by a broken line, and the field edge 1 is shown by a two-dot chain line. The ceiling 2 is not shown in these figures.

Further, in the present embodiment, as described above, the rail 20 on the long side of the installation structure 10 in plan view is the rail 20 to which the strut device T is attached. Further, the installation interval of the field edge 1 is set to 300 to 360 mm, and the installation interval of the long rail 20 is set to be larger than the installation interval of the field edge 1.

The strut device T includes, as main members, a plate-shaped member 30 whose plate surface contacts the ceiling 2 and a rod-shaped member 40 which is connected to the plate-shaped member 30 and whose end (lower end) moves in the rail 20. These main members are attached between the ceiling 2 and the rail 20.

The length of the plate-shaped member 30 is set larger than the length between the rails 20 on the upper surface of the installed structure 10, and is preferably 400 to 1200 mm, for example. The width dimension of the plate member 30 is preferably 30 to 300 mm. The rod-shaped member 40 has an appropriate size according to the size between the ceiling 2 and the installed structure 10. Further, it is desirable that two rod-shaped members 40 be provided at both ends of the plate-shaped member 30 in the longitudinal direction. That is, in the present embodiment, the bracing device T is configured to include one plate-shaped member 30 and two rod-shaped members 40. The distance between these two rod-shaped members 40 is preferably 300 to 900 mm in consideration of the length of the plate-shaped member 30.

The bracing device T is attached in any of the following installation modes (A) and (B).
(A) One tensioning device T is slidably attached to one of the rails 20 at an appropriate position.
(B) One strut device T is attached so as to bridge between the rails 20 facing each other.

In the installation mode of (A), as shown in FIGS. 1(a) and 2(a), a plurality of field edges 1 are arranged substantially parallel to each other and in a direction substantially orthogonal to the rail 20. This is the mode selected when there is.

In the example of FIG. 1( a ), the installation structure 10 is provided with three bracing devices T, each of which is arranged along one rail 20. The bracing device T can be disposed at an appropriate position on the rail 20 in the longitudinal direction, and in FIG. 1A, the plate-shaped material 30 intersects the field edge 1 and overlaps in plan view. It is arranged at an appropriate position. That is, the lower ends of the two rod-shaped members 40 are arranged in the rail groove 22 of the rail 20, and the plate-shaped member 30 is arranged so as to contact the ceiling 2. It is fixed between the rail 20 and the ceiling 2.

In the installation mode of (B), as shown in FIGS. 1(b) and 2(b), a plurality of field edges 1 are substantially parallel to each other, and on the rail 20 on the long side of the installed structure 10. This is the mode selected when they are arranged substantially in parallel. In this installation mode, each of the tensioning devices T is arranged so as to be bridged over two rails 20.

In the example of FIG. 1( b ), the installation structure 10 is provided with three bracing devices T substantially in parallel, and each of the bracing devices T is arranged so as to be bridged between two rails 20. There is. Since the field edge 1 is arranged substantially parallel to the rail 20, the plate-shaped member 30 of the strut device T overlaps with the field edge 1 in a plan view. Since the bracing device T is arranged so as to span the field, it always crosses the field edge 1. Therefore, the bridging position may be an arbitrary position, and the rod-shaped member 40 does not have to be slide-adjusted in the rail in order to determine the positional relationship with the field edge 1.

The above installation modes (A) and (B) may be selected after confirming the arrangement direction of the field edge 1 when attaching the bracing device T. In this way, with the above-mentioned dimensional relationship, it is not necessary to confirm the exact position of the field edge 1, but only by confirming the arrangement direction. Can be easily mounted.

Next, details of the installation mode of the bracing device T in the case of (A) above will be described with reference to FIGS. 1(a), 2(a) and 3 to 5.

3A is a vertical cross-sectional view corresponding to the line AA in FIG. 2A, FIG. 3B is a vertical cross-sectional view showing another example, and FIG. 3C is a rear view of the plate-shaped member 30. Is. Further, FIG. 4A is an exploded vertical cross-sectional view showing a fixing structure of an end portion of the rod-shaped member 40 on the rail 20 side corresponding to the line BB of FIG. 2A, and FIG. 4B is the same fixing. It is a longitudinal cross-sectional view of the structure. FIG. 4C is a vertical cross-sectional view showing the fixing structure of the end portion of the rod-shaped member 40 on the rail 20 side, which corresponds to the line CC in FIG. 2A. FIG. 5A is an exploded vertical cross-sectional view showing a fixing structure of the end portion of the rod-shaped member 40 on the ceiling 2 side corresponding to the line CC in FIG. 2A, and FIG. 5B is the same fixing structure. FIG.

As shown in FIGS. 3A and 3B, the bracing device T is fixed so that the rod-shaped member 40 is braced between the plate-shaped member 30 and one rail 20. FIG. 3A is a view corresponding to the example of FIG. 2, in which the plate-shaped member 30 is overlapped with the two field edges 1 so as to intersect with each other in a plan view, and the bar-shaped member is provided directly below each of the intersections. 40 is arranged so as to extend downward. Since the dimension of the plate-shaped member 30 in the longitudinal direction is larger than the interval of the field edge 1, both rod-shaped members 40 can be arranged at the intersections as in the example of FIG.

In the example of the present embodiment, the plate member 30 is made of a polymer material of a hard plate member 32 made of metal, synthetic resin, etc. and a cushion member 35 made of rubber. It is desirable that these are polymerized and fixed in advance.

Further, in the hard plate member 32, three elongated holes 33 are formed so as to extend linearly along the longitudinal direction, and when the cushion member 35 is fixed, as shown in FIG. The opening of the elongated hole 31 having a bottom portion appears on the back surface side. The elongated hole 31 can be inserted with the rod-shaped member 40 at a proper position in the longitudinal direction. The long hole 33 of the hard plate member 32 may be one extending from the end in the longitudinal direction to the other end, but in order to maintain the strength of the hard plate member 32, the non-opening portion 34 as shown in the figure. It is desirable to provide a plurality of elongated holes 33 via the.

As described above, since the attachment position of the rod-shaped member 40 to the plate-shaped member 30 is variable in the longitudinal direction of the plate-shaped member 30, the two rod-shaped members 40 are arranged at the appropriate positions of the three elongated holes 31. can do. The lower end portion (the end portion on the rail 20 side) of the rod-shaped member 40 can be arranged at a variable position as a matter of course because the mounting target is the rail groove 22.

As described above, the position of the rod-shaped member 40 of the strut device T can be adjusted by sliding in the rail groove 22 at the lower end, and can be adjusted at the upper end within the range of the elongated hole 31 of the plate-shaped member 30 in the longitudinal direction. Can be adjusted. If such position adjustment is performed in accordance with the interval of one field edge, the bracing device T can be arranged at an appropriate position shown in FIG.

If the length of the plate-shaped member 30 is made longer than the interval between the field edges 1 as in the present embodiment, as shown in FIG. The device T can be attached. In this case, the position of the rod-shaped member 40 does not have to be directly under the intersection, and for example, one rod-shaped member 40 may be arranged at the position shown by the chain double-dashed line in FIG. Even in this case, the strut device T utilizing the strength of the field edge 1 can be attached.

Further, as shown in FIG. 3B, even when the plate-shaped member 30 overlaps only one field edge 1, two rod-shaped members 40 are provided on both outer sides of the field edge 1 as shown in the example. For example, the strut device T utilizing the strength of the field edge 1 can be attached. Of course, the rod-shaped member 40 may be arranged directly below the intersection shown by the chain double-dashed line in FIG.

Note that the number of rods 40 is not limited to two. A bracing device T having three or more rod-shaped members 40 (for example, three rod-shaped members 40 including a two-dot chain line as shown in FIGS. 3A and 3B) with respect to one plate-shaped member 30. May be

After variously adjusting the position of the rod-shaped member 40 as described above, the bracing device T can be braced between the ceiling 2 and the installed structure 10 (rail 20) to be pinched and fixed. In order to stretch the strut device T, each of the lower end portion and the upper end portion of the rod-shaped member 40 may be fixed as described below.

The rod-shaped member 40 has a rail-side screw portion 41 formed at the lower end portion and a ceiling-side screw portion 42 formed at the upper end portion, and is configured to be fixed vertically by screwing using these. Hereinafter, each fixing mode will be described.

The lower end of the rod 40 is fixed by the fixing means 45. In the example of FIG. 2, a fixing means 45 including a mounting member 50 arranged in the rail groove 22 and a rail pressing member 60 is used. The fixing means 45 will be described with reference to FIG.

The mounting member 50 is made of metal, synthetic resin, or the like, and is formed in a rectangular parallelepiped shape that generally matches the cross-sectional shape of the rail groove 22, and an upper surface side is formed with a female screw concave portion 51 having a bottom portion 52 and extending vertically. Has been done. The rail pressing member 60 is made of metal, synthetic resin, or the like in a truncated cone shape, and has a female screw hole 61 penetrating vertically in the center of the plane.

The mounting member 50 may be arranged at an appropriate position in the rail groove 22 with the opening of the female screw recess 51 facing upward. The mounting member 50 may be mounted from the end opening in the longitudinal direction of the rail 20, and once mounted, there is no risk that the mounting member 50 will slip out of the groove opening 23 of the rail groove 22 by the retaining piece 24.

With respect to the mounting member 50 and the rail pressing member 60 arranged on the upper surface of the rail 20, the rail-side screw portion 41 of the rod-shaped member 40 is screwed into the female screws of the rail pressing member 60 and the mounting member 50, respectively. The three members are connected together. When the rail pressing member 60 is rotationally operated and screwed so that the lower end of the rod-shaped member 40 contacts the bottom portion 52 of the female screw recess 51, the retaining piece 24 of the rail 20 serves as the mounting member 50 and the rail pressing member 60. The rod-shaped member 40 is fixed to the rail 20 by being firmly sandwiched between the rails 20.

In the state where the screw is loosened, as shown in FIG. 4(c), the connected three members are placed at appropriate positions in the positional relationship with the field edge 1 in the longitudinal direction of the rail 20 (the direction of the outlined arrow). You can slide it. After the position is determined, the rail pressing member 60 may be further rotated and firmly fixed.

As described above, since the three members of the rod-shaped member 40, the mounting member 50, and the rail pressing member 60 have a structure in which they can be fixed to the retaining piece 24 by screwing them together, the lower end portion of the rod-shaped member 40 has the rail 20. Fixed in the desired position.

In order to easily attach and fix the rod-shaped member 40 to the rail 20, the rod-shaped member 40 and the rail pressing member 60 are previously screwed in a state where the lower end of the rod-shaped member 40 protrudes from the bottom surface side of the rail pressing member 60. If they are combined, they should be united. Then, the projecting portion of the rod-shaped member 40 may be mounted in the female screw recess 51 of the mounting member 50. Further, it is desirable to attach the rod-shaped member 40 to the rail 20 after the upper end portion is pressed against the plate-shaped member 30 arranged on the ceiling 2.

Next, the manner of fixing the upper end of the rod 40 will be described with reference to FIG.

The upper end of the rod 40 is fixed by using the ceiling-side pressing member 65. The ceiling-side pressing member 65 has the same shape as the rail pressing member 60, and the rail pressing member 60 can be used upside down. That is, the ceiling-side pressing member 65 is made of metal, synthetic resin, or the like in a truncated cone shape, and has a female screw hole 66 penetrating in the vertical direction at the center, and the truncated cone is arranged upside down. ..

As shown in FIGS. 5A and 5B, the upper end portion of the rod-shaped member 40 is a ceiling-side pressing member 65 in which the ceiling-side screw portion 42 is screwed, and the plate-shaped member 30 arranged on the ceiling 2 is arranged from below. It is fixed by pressing. At this time, the upper end of the rod-shaped member 40 projects from the upper surface of the ceiling-side pressing member 65 and is arranged in the elongated hole 31 of the plate-shaped member 30.

The fixed state shown in FIG. 5B is a state where the lower end of the rod 40 is fixed to the rail 20 as shown in FIGS. 4B and 4C.

In this way, the upper end of the rod-shaped member 40 can also be fixed to the ceiling 2 together with the plate-shaped member 30 by the ceiling-side pressing member 65. If the plate-shaped member 30 is arranged at a fixed position, the rod-shaped member 40 may be attached after it is temporarily fixed to the ceiling 2 with an adhesive or the like.

In this way, the bracing device T is fixed between the ceiling 2 and the rail 20, and fixed between the field edge 1 and the installed structure 10.

To install the strut device T between the ceiling 2 and the rail 20, first, the plate member 30 (the cushion member 35) is pressed by the upper end portion of the rod member 40, and then the lower end portion is fixed to the rail 20. Then, by fixing the upper end portion to the ceiling 2, it can be carried out smoothly.

With this procedure, if the lower end of the rod 40 is fixed to the rail 20, the pressing of the upper end against the plate 30 is loosened. Then, by fixing the upper end of the rod 40, the rod 40 acts so as to move downward, and the ceiling-side pressing member 65 presses the plate 30, whereby the rod 40 moves up and down. Will be firmly fixed in.

Further, since the upper end of the rod-shaped member 40 may be arranged within the thickness of the plate-shaped member 30, the rod-shaped member 40 has a length dimension such that the upper end thereof fits within the thickness of the plate-shaped member 30. Therefore, some error is allowed in the length of the rod 40.

Next, the bracing device T in the case of the above-mentioned (B) installation mode will be described with reference to FIGS. 1(b), 2(b) and 6. FIG. 6 is a vertical sectional view corresponding to the line DD in FIG.

In this installation mode, as shown in FIG. 6, the rod-shaped member 40 is fixed so as to be stretched between the plate-shaped member 30 and the two rails 20. In the installation mode of (B) as well, the same tensioning device T as in the case of (A) is used, but since the disposition positions of the two rod-shaped members 40 with respect to the plate-shaped member 30 are variable, two rod-shaped members are used. The position of the material 40 may be adjusted according to the two rails 20. The upper end and the lower end of the rod-shaped member 40 are fixed in the same manner as in (A), and the description thereof will be omitted.

Further, when the rail 20 is arranged parallel to the field edge 1 as shown in FIG. 2B and the rail 20 and the field edge 1 overlap each other in a plan view, the tensioning device T is installed in the direction shown in FIG. It may be arranged at the position indicated by the two-dot chain line.

Although the tensioning device T in which the interval between the rod-shaped members 40 is variable is illustrated above according to the installation mode or the like, the interval between the rod-shaped members 40 cannot be adjusted depending on the dimensional relationship between the field edge 1 and the rail 20. May be. That is, the rod-shaped member 40 may be fixed at a specific position on the plate-shaped member 30. Moreover, you may use the tension|pulling apparatus which integrally had the ceiling receiving part replaced with the plate-shaped material 30, and the leg part replaced with the rod-shaped material 40.

Further, in the above embodiment, the two long rails provided on the upper surface of the installed structure 10 are the rails 20 to which the tensioning device T is attached, but the tensioning device T is provided on the two short rails 25 facing each other. It may be attached.
