Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a nut mounting structure that is slidably mounted on a rail and mounted inside the rail.

[0002]

[Prior Art]

 5 to 9 show conventional housings for housing electronic devices.

As shown in FIGS. 5 and 6, the left and right inner side walls 1 a, 1 a of the housing 1 are provided with a pair of vertical beams 3, 3, respectively. The rail 4 is screwed along the vertical beam 3. The rail 4 has a substantially C-shaped cross section, and a square plate nut 6 as shown in FIGS. 8 and 9 is accommodated in the rail 4 in a slidable manner with respect to the rail 4. The screw hole 6a of the plate nut 6 is positioned to face the front opening 4a of the rail 4. Further, a coil spring 8 is provided on the bottom surface 6b of the plate nut 6, and the plate nut 6 is inserted into the rail 4 together with the coil spring 8 from the end side opening 4b of the rail 4, as shown in FIG. The pressing force of the coil spring 8 presses against the peripheral edge of the front opening 4 a of the rail 4. Therefore, the plate nut 6 can be slid with respect to the rail 4 and can be held by the rail 4 at a desired position on the rail 4.

A guide rail 10 is attached to the plate nut 6 positioned at a desired position on the rail 4 with a screw 11, and the guide rail 10 is fixed at a desired position on the rail 4. Then, the electronic device 12 is housed in the housing 1 by being mounted on the guide rail 10.

According to this conventional case, since the plate nut 6 can be slid with respect to the rail 4, the guide rail 10 can be attached to a desired position of the rail 4. However, since the plate nut 6 has to be inserted from the end side opening 4b of the rail 4 and the plate nut 6 has to be slid in the rail 4 to a predetermined position of the rail 4 where the guide rail 10 is to be fixed, The work of attaching the nut 6 to the was complicated. Further, it is difficult to insert the nut 6 and the coil spring 8 from the end side opening 4b of the rail 4 while the coil spring 8 is compressed.

[0006]

[Problems to be solved by the device]

 As described above, in the above-mentioned nut mounting structure, the nut had to be inserted from the opening on the end side of the rail, and this nut had to be slid in the rail to the specified position on the rail. The work was complicated. Also, it was difficult to insert the nut and the spring provided on the bottom surface of the nut into the rail through the opening on the end side.

The present invention has been made to solve the above-mentioned conventional drawbacks, and provides a nut mounting structure in which a nut can be easily mounted at a desired position of a rail for slidably holding the nut. The purpose is to do.

[0008]

[Means for Solving the Problems]

 In the present invention, a nut is slidably accommodated in the rail, an opening is formed in the rail to expose the screw hole of the nut to the outside of the rail, and the nut is provided between the nut and the bottom surface of the rail. Is a nut mounting structure in which a spring is provided for pressing the nut toward the peripheral edge of the opening of the rail, and the nut has a length in the lateral direction smaller than the width of the opening and a length in the longitudinal direction. Is formed to be larger than the width of the opening, and the nut is provided with a convex portion on the surface opposite to the surface contacting the spring and where the screw hole is formed. The protrusion is formed to have a width that can be fitted into the opening at the position of the nut oriented in the direction in which the longitudinal direction of the nut housed in the rail intersects the peripheral edge of the opening. Been That.

[0009]

[Action]

 In the present invention, the nut is oriented so that the longitudinal direction of the nut is parallel to the peripheral edge of the rail opening, and the spring positioned between the bottom of the rail and the nut is compressed by the nut into the rail opening into the rail. Insert the nut, rotate the nut in the rail, orient the nut in the direction in which the longitudinal direction of the nut intersects the peripheral edge of the opening, and press the spring force to fit the convex portion of the nut into the rail opening. , The nut is attached to the rail.

[0010]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a view showing a state where the nut is finally attached to the rail, FIG. 2 is a view showing a state immediately after the nut is inserted from an opening portion of the rail, FIG. 3 is a front view of the nut, and FIG. It is CC sectional view taken on the line of FIG.

The rail 21 according to the present invention is configured to be screwed to the vertical beam 3 of the housing 1 shown in FIG. 5 and FIG. 6, and like the conventional rail 4, the cross section has a substantially “C” shape. And a linear opening 21a having a width W1 is formed on the front surface side.

As shown in FIGS. 3 and 4, the nut 23 slidably attached to the rail 21 is formed into a substantially rectangular shape, and its width W2 is equal to that of the rail 21. It is made slightly smaller than the width W1 of the opening 21a, and its length L is made sufficiently larger than the width W1 of the opening 21a. However, the diagonal length of the nut 23 is smaller than the distance between the left and right inner walls 21b, 21b of the rail 4.

Further, the nut 23 has a screw hole 23a formed in the central portion for screwing with the above-mentioned screw 11, a recess 23c is formed in the bottom surface 23b, and a coil spring is formed in the recess 23c. One end side of 25 is fixed. Further, a convex portion 23e is formed on a portion of the nut 23, which is a surface 23d on the side opposite to the bottom surface 23b and in which a screw hole 23a is formed. The width W3 of the protrusion 23e in the longitudinal direction of the nut 23 is slightly smaller than the width W1 of the opening 21a. Next, the work of attaching the nut 23 to the rail 21 will be described.

When the nut 23 is attached to the rail 21, first, as shown in FIG. 2, the nut 23 is oriented so that the longitudinal direction of the nut 23 is parallel to the peripheral edge of the rail opening 21a, and the spring 25 is attached to the rail 21. Insert the nut 23 into the rail 21 while pressing it to the bottom surface 21c side. Then, the nut 23 is rotated in the direction of the arrow shown in FIG. 1, and the nut 23 is oriented so that the longitudinal direction of the nut 23 intersects the peripheral edge of the opening 21a, and the pressing force of the nut 23 that compresses the spring 25 is loosened. .. As a result, the nut 23 is pressed against the peripheral edge of the rail opening 21a by the elastic force of the spring 25, and the convex portion 23e of the nut 23 is fitted into the opening 21a. Be done.

[0016]

[Effect of the device]

 As described above, according to the present invention, the nut is inserted from the opening of the rail, the nut is rotated at a predetermined angle in the rail at the insertion position of the nut, and the convex portion is formed on the rail by using the pressing force of the spring. The nut can be attached to the desired position of the rail by a simple operation of fitting it into the opening of the rail. Therefore, it is not necessary to insert the nut from the opening formed at the end of the rail as in the past, and it is necessary to slide the nut in the rail from the opening at the end of the rail to the position where the nut of the rail is to be attached. Nor.
