Abstract

PROBLEM TO BE SOLVED: To provide a means which can easily settle a case to a frame pen if it is a case different in height for an electric apparatus or the like. SOLUTION: A case 1 is placed at the bottom 2c of a frame 2. A retaining bar 3 consisting of a round bar or a semiround bar lacking its top is laid horizontally, in abutment on the topside 1a of the case 1. Both ends 3a of the retaining bar 3 are provided with two screw holes 3b each. The section corresponding to the screw hole 3b of the retaining bar 3 at the flank 3s of the frame 2 is provided with zigzag through holes where semicircular lengthy slits 4 mutually centering on the ends 4a of the slits 4 link with one another. A screw 6 is penetrated into the slit 5, and it is screwed into the screw hole 3b at the end 3a of the retaining bar 3 so as to lock the retaining bar 3 in the specified position of the frame 2. The position of lock is made the one where the bottom of the retaining bar 3 abuts on the topside 1a of the box 1, putting the screw 5 at the end of the retaining bar 3 in the position of the end 4a of one slit 4, and sliding the other screw 5 in the direction of long diameter of the slit 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a box to a frame which can easily be fixed to the frame even if the box has a different height such as an electronic device.

[0002]

2. Description of the Related Art In a system of an electronic apparatus, a plurality of boxes accommodating respective components are held in a plurality of frames, respectively, and are often attached to a rack or the like. In this case, generally, the height of the box housing each component constituting the system or the like is not uniform. Therefore, it is necessary to hold boxes having different heights, and it is necessary to prepare different frames for holding the boxes for each box, such as opening holes in different portions of each frame and screwing the boxes. was there. For this reason, not only is it not economical, but there is a possibility that a tight holding state cannot be maintained, for example, a shift occurs in holding the box body to the frame.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a means for easily fixing a box having different heights, such as electronic equipment, to a frame. And

[0004]

In a structure for mounting a box body such as an electronic device on a frame for holding the box body on a frame, a round bar or a horizontal bar abutting on the upper surface of a box body placed on the bottom of the frame. A holding rod provided with two screw holes at both ends formed of a semi-circular bar, and a partial circle centered on a predetermined portion of the other through hole on one side of the frame corresponding to each screw hole of the holding rod. The box body is formed by providing a through hole that is an arc-shaped long hole, and locking the holding rod at a predetermined position of the frame with a screw that penetrates the through hole and is screwed into a screw hole at the end of the holding rod. The structure is to be held on the frame.

The one through hole is a circular hole having a diameter penetrating the screw, and the other through hole is a semicircular long hole centered on the circular hole.

[0006] The through-holes are staggered through-holes in which semi-circular arc-shaped long holes centered on the ends of the long holes are linked to each other.

The outer periphery of the holding rod is covered with an elastic body such as a rubber cushion.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a side view of one embodiment of a structure for mounting a box to a frame according to the present invention, and FIG.
It is a front view, (C) top view, (D) Engagement part enlarged view.
One box 1 for storing electronic devices constituting the system and the like
Is held in the frame 2. Frame 2 holding box 1
Is attached to a rack through which bolts and the like penetrate through through holes 2b opened in the ears 2a on the rear surface of the frame 2 to constitute one system or the like. The mounting mechanism for holding the box 1 on the frame 2 is as follows. First, the box 1 is placed on the bottom 2 c of the frame 2. A holding rod 3 made of a round bar or a semi-round bar with an upper part cut off is placed in contact with the upper surface 1a of the box.
Each of the two ends 3a of the holding rod 3 has two screw holes 3b.
Is provided. Screw hole 3 of holding rod 3 on side 2d of frame 2
In a portion corresponding to b, a staggered through hole in which semi-circular arc-shaped long holes 4 centered on mutual ends 4a of the long holes 4 is provided. A screw 5 penetrates into the long hole 4 and is screwed into a screw hole 3 b at an end 3 a of the holding rod 3 to lock the holding rod 3 at a predetermined position on the frame 2. The locking position is such that the screw 5 at the end of the holding rod 3 is placed at the position of the end 4a of one of the long holes 4 and the other screw 5 is slid in the major axis direction of the semicircular long hole 4. , The bottom of the holding rod 3 is in contact with the upper surface of the box 1. By adopting such a structure for attaching the box to the frame, the other screw 5 engages with the end 4a of the elongated hole 4 when positioning the holding rod 3, so that the height h of the box 1 is increased. Can be easily fixed to the frame 2.

FIG. 2 is an enlarged view of a locking portion of another embodiment of the structure for attaching a box to a frame according to the present invention. In the same manner as described above, the holding rod 3 is brought into contact with the upper surface 1 a of the box 1 and held on the frame 22. A circular hole 26 having a diameter through which the screw 5 penetrates is opened at a position corresponding to one screw 5 of the holding rod 3 on the side surface 22 d of the frame 22. The through hole corresponding to the other screw 5 of the holding rod 3 is a semi-circular elongated hole 2 centered on the circular hole 26.
4 is assumed. When holding the box 1 on the frame 2, the screw 5 at the end of the holding rod 3 is placed at the position of the circular hole 26, and the other screw 5 is slid in the major axis direction of the semicircular long hole 24. , The bottom of the holding rod 3 is in contact with the upper surface 1 a of the box 1. In addition, when the outer periphery of the holding rod 3 is covered with the rubber cushion 27 and the box 1 is held by the holding rod 3, the holding rod may be held in close contact with the upper surface 1 a of the box 1. .

[0010]

According to the present invention, in a structure for mounting a box body such as an electronic device on a frame for holding the box body on the frame, a round bar or a semi-round bar abutting on the upper surface of the box body mounted on the bottom of the frame. A holding rod provided with two screw holes at both ends, and a partially arcuate long hole centered on a predetermined portion of the other through hole on one side of the frame corresponding to each screw hole of the holding rod. The box body is held on the frame by locking the holding rod at a predetermined position of the frame with a screw that penetrates the through hole and is screwed into a screw hole at the end of the holding rod. With this structure, even boxes having different heights, such as electronic devices, can be easily fixed to the frame.
