By the way, even if the board is installed properly, it may be required to replace the equipment in the board, introduce additional measuring equipment, change the wiring route, etc. due to the passage of time or changes in the environment. .. At this time, it may be necessary to adjust the position and spacing of the inner unit rails because the inside of the panel is used differently from the initial installation. However, with the conventional board structure, it was not possible to change the spacing between the installed internal unit rails. In addition, even if an attempt was made to install a new internal unit rail at the site where it was installed, it was not easy to adjust the dimensions at the site.

The inventor of this case tried to solve this problem by diligently examining this point. An object of the present invention is to provide a structure capable of easily changing the position and spacing of the inner unit rails.

In order to solve the above problems, a cabinet equipped with a bolt holder, a mounting rail horizontally mounted using the bolt holder, a slide stud held on the mounting rail so as to be slidable, and an internal unit that supports the internal unit. A rail is provided, and the internal unit rail has an in-panel equipment mounting structure fixed to the mounting rail using slide studs.

Further, it is preferable that the mounting rail has a corrugated unevenness facing the slide stud.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a structure capable of easily changing the position and spacing of the inner unit rails.

It is a front view of the board of an embodiment. It is a side view of the mounting rail made of a substantially C-shaped member. It is a side view which shows the state which the slide stud is incorporated in the mounting rail of FIG. It is a perspective view which shows the state which the slide stud is incorporated in the mounting rail which provided the corrugated unevenness. It is a VV arrow view of FIG. FIG. 5 is a view taken along the line VI-VI of FIG. It is a figure which showed the relationship between the inclination of the slide stud incorporated in the mounting rail of FIG. 4 and the unevenness of a wave shape. It is a figure which showed the relationship between the inclination of a slide stud and the unevenness of a wave shape when a slide stud different from that shown in FIG. 7 was incorporated in a mounting rail. It is a front view of the board which showed the state which the inner unit rail shown in FIG. 1 was moved to the left side. It is the figure which showed the state which fixed the mounting rail via the adjustment metal fitting.

A mode for carrying out the invention is shown below. As shown in FIG. 1, in the in-panel equipment mounting structure of the present embodiment, the cabinet 1 provided with the bolt holder 11, the mounting rail 2 horizontally mounted using the bolt holder 11, and the mounting rail 2 are slidably moved. It includes a slide stud 21 that is held so that it can be held, and an internal unit rail 4 that supports the internal unit unit 3. Further, the internal unit rail 4 is fixed to the mounting rail 2 by using the slide stud 21. Therefore, by changing the position of the slide stud 21, it is possible to change the position and spacing of the inner unit rail 4. Therefore, it is possible to easily change the position and spacing of the inner unit rail 4.

Bolt holders 11 into which bolts are screwed are provided at four corners of the cabinet 1 of the board of the present embodiment. The bolt holder 11 is used for mounting bolts used for fixing the mounting rail 2. Further, the mounting rail 2 is fixed so that the longitudinal direction extends in the horizontal direction.

The mounting rail 2 shown in FIG. 2 is configured to have a substantially C-shape in cross-sectional view, and is provided with scales at predetermined intervals along the longitudinal direction. The slide stud 21 is incorporated into the mounting rail 2 as shown in FIG. The slide stud 21 incorporated in the mounting rail 2 can slide and move in the longitudinal direction of the mounting rail 2. Screw fixing holes 22 used for fixing the mounting rail 2 are provided on both ends of the mounting rail 2 in the longitudinal direction. The screw fixing hole 22 of the present embodiment is a long hole, and is provided in a flat plate-like portion of the mounting rail 2.

In the example shown in FIGS. 4 to 7, the mounting rail 2 has a wavy unevenness 23 facing the slide stud 21. The slide stud 21 is movably supported by being sandwiched between the corrugated unevenness 23 from both the upper and lower sides. Here, in order to form the mounting rail 2 having the wavy unevenness 23, a resin member having continuous unevenness is inserted into the metal rail member 24 having a substantially C-shaped cross section. doing. Further, in this example, the heads of the bolt-shaped slide studs 21 are arranged so as to be located between the wavy irregularities 23.

In the examples shown in FIGS. 4 to 7, when the head provided in a non-circular shape has a predetermined orientation, the wavy unevenness 23 restricts the slide movement of the slide stud 21, while the head is predetermined. If the orientation is not the same, the slide stud 21 is configured to be able to freely slide and move in the mounting rail 2 regardless of the presence of the wavy unevenness 23. Since the wave-shaped unevenness 23 of the present embodiment repeats the unevenness at regular intervals, the position of the slide stud 21 can be confirmed using this unevenness as a guide.

Here, a metal bolt is covered with a resin cap in order to form a slide stud 21 that can come into contact with the wavy unevenness 23. The cap has an eccentric circular shape or the like so that the slide stud 21 can come into contact with the wavy unevenness 23. Specifically, by rotating the slide stud 21 in a freely slidable state so as to twist it by approximately 90 degrees, the convex portion provided on the cap is configured to be able to engage with the wavy unevenness 23. There is. If this convex portion is engaged with the wave-shaped unevenness 23, the slide stud 21 can be efficiently positioned.

The slide stud 21 can have various shapes. For example, as shown in FIG. 8, a configuration having a polygonal head may be provided. By doing so, it is possible to make the length in the lateral direction relatively short while ensuring the length in the longitudinal direction.

In the present embodiment, if the slide stud 21 is loosened and the slide stud 21 is changed to a slidable direction, the slide stud 21 can be freely slid and moved in the left-right direction. As a result, the inner unit rail 4 can be moved in the horizontal direction. Therefore, for example, by moving the inner unit rail 4 from the state shown in FIG. 1 as shown in FIG. 9, a new device is moved to the right side in the panel. Space S1 for installation can be secured.

Further, when it is desired to move the mounting rail 2 serving as the guide rail of the slide stud 21 in the vertical direction, the adjusting metal fitting 5 may be used as shown in FIG. In the example shown in FIG. 10, the adjusting metal fitting 5 having a plurality of holes 51 is attached by using the bolt holder 11. Since these holes 51 are provided so as to be spaced apart in the vertical direction, an appropriate hole 51 may be selected according to a desired height of the mounting rail 2. For example, in the example shown in FIG. 10, the adjusting bracket 5 is arranged so as to extend upward from the bolt holder 11 in order to provide the space S2 for installing the device in the lower part of the panel, and the mounting rail is arranged above the bolt holder 11. It is configured so that 2 is located.

As in the present embodiment, if the internal unit rail 4 is configured to be slidable in the left-right direction, by adjusting the position of the internal unit rail 4, a space for installing communication equipment or the like is provided on the right side or the left side of the cabinet 1. Can be provided. Further, in the present embodiment, the transfer member 8 is attached so as to bridge the two internal unit rails 4, and the internal unit 3 is fixed to the transfer member 8, but the internal unit rails 4 are connected to each other. Since the interval between the two can be adjusted, the degree of freedom of change can be increased even when the type of the transfer member 8 or the internal unit 3 is changed.

Although the above description has focused on some embodiments, the present invention is not limited to the above embodiments and can be in various embodiments. For example, it is possible to use an adjusting bracket extending downward from the bolt holder so that the mounting rail is located below the bolt holder.

The attachment of the internal unit does not have to be done via the transfer member. For example, the internal unit unit may be attached to the internal unit rail without using a transfer member.

The slide stud can be nut-shaped instead of bolt-shaped.

Corrugated galvanized iron does not need to be provided on both the upper and lower sides of the mounting rail. For example, the configuration may be provided only on the upper side or the lower side of the slide stud.

The wavy unevenness does not need to be provided with individual concaves and convexes in a line-symmetrical manner, and can be configured to be provided in an asymmetrical manner.
