BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a frame such as a communication device having a caster on a bottom surface to a floor.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 2, a fixed structure of this type includes a frame 1 having casters 2 attached to four corners of a bottom surface, and a U-shaped cross section formed slightly lower than the casters 2. And a pair of flat plate-shaped height adjustment plates 25. A screw hole 1a provided on the bottom surface of the frame 1 is attached to the mounting hole 22a of the upper surface portion 22 of the floor fixing bracket 22. By screwing the screw 27, the floor fixing bracket 22 is attached to the bottom surface of the frame 1, and then the height adjusting plate 25 is inserted between the floor fixing bracket 22 and the floor.
The screw 28 is screwed into the screw hole 25a of the floor fixing bracket 22 from the mounting hole 23a of the lower surface portion 23 of the floor fixing bracket 22, so that the height adjustment plate 25 is fixed to the floor fixing bracket 22 so as to be at the same height as the casters 2. Installed.

[0003]

In the above-mentioned conventional fixing structure of a frame, it is necessary to lift the frame when inserting the height adjusting plate between the floor fixing bracket and the floor. In addition, there is a drawback that there is a risk that the portion holding the frame housing may be damaged or the frame housing may fall. Further, once fixed to the floor, there is a problem that removal is troublesome and cannot be easily moved during maintenance.

Accordingly, the present invention has been made in view of the above-mentioned conventional disadvantages or problems, and has as its object to eliminate the necessity of any screw tightening between the bottom plate and the frame housing. Another object of the present invention is to provide a fixing structure for a frame housing that can be fixed without lifting the frame housing without lifting the frame housing, thereby facilitating the fixing and facilitating movement during maintenance.

[0005]

In order to achieve this object, a fixing structure for a frame housing according to the present invention comprises a frame having casters on the bottom surface, and a frame mounted on one end of the bottom surface of the frame. At least one pair of L-shaped first engagement pieces having an engagement hole in a horizontal portion, and at least one L-shaped second engagement piece attached to the other end of the bottom surface of the frame housing. And a first vertical portion provided with an engagement hole with which the first engagement piece engages and a cutout portion for escaping contact with the second engagement piece is provided on a front surface portion, A second vertical portion provided with an engagement hole with which the second engagement piece is engaged is provided on a bottom plate formed on a rear surface portion, and an engagement hole of the first engagement piece. The bottom plate is fixed to the floor, and the first and second holes are formed in respective engagement holes of the bottom plate. Engaging the engaging piece, in which is engaged the engaging projection of the locking bar to the engagement hole of the first engaging piece.

[0006]

In the present invention, the frame is moved along the floor, and the first and second engagement pieces attached to the bottom surface of the frame are engaged with the respective engagement holes of the bottom plate. When the engagement protrusion of the bar member is engaged with the engagement hole of the first engagement piece, the frame housing is fixed to the bottom plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a fixing structure of a frame housing according to the present invention. In the figure, a pair of L-shaped first engagement pieces 4 are attached to the front end side of the bottom surface of the frame housing 1, and a horizontal portion 5 of the engagement piece 4 has a slit-like shape. An engagement hole 5a is formed, and a chamfered portion 5b is provided at a corner of the tip. An L-shaped second engagement piece 6 is attached to the rear end of the frame housing 1 so as to be located substantially at the center of the first engagement piece 4. A chamfered portion 7a is provided at the tip corner of the horizontal portion 7 of FIG.

Reference numeral 10 denotes a bottom plate, which includes a bottom portion 11 having a mounting hole 11a, a first vertical portion 12 on the front side, and a second vertical portion 13 on the rear side. At both ends of the first vertical portion 12, a pair of rectangular engagement holes 12a into which the horizontal portion 5 of the first engagement piece 4 is inserted and engaged are formed. A notch 12b for escape is provided so that the second engagement piece 6 does not abut. A rectangular engaging hole 13a into which the vertical portion 7 of the second engaging piece 6 is inserted and engaged is formed in the center of the second vertical portion 13. 15 is
Engagement projections 15a that engage with the respective engagement holes 5a of the first engagement piece 4 at both ends are bar members that project downward.

The fixing structure of the frame housing of the present invention is configured as described above, and the assembling method will be described below. First, the bottom plate 10 is attached to the floor with the screws 17. Next, the frame 1 is moved from the front side of the bottom plate 10 in the direction of arrow A, and the second engagement piece 6 of the frame 1 is
And the horizontal portion 7 of the second engagement piece 6 is inserted into and engaged with the engagement hole 13a of the second vertical portion 13, and at the same time, the horizontal portion 5 of the first engagement piece 4 is It is inserted and engaged with the engagement hole 12a of the vertical portion 12. Then, the engagement protrusion 15a of the bar member 15
Is engaged with the engagement hole 5 a of the first engagement piece 4, the frame 1 is fixed to the bottom plate 10. When the frame 1 is moved for maintenance or the like, the engagement between the engagement projection 15a of the bar member 15 and the engagement hole 5a of the first engagement piece 4 is released. By moving 1 in the direction opposite to the arrow A, the fixing to the bottom plate 10 can be released.

[0010]

As described above, according to the present invention, the bottom plate is fixed to the floor in advance, and is moved to the engagement holes of the bottom plate by using the casters of the frame housing. Then, the engaging piece attached to the bottom surface of the frame is engaged, and then the bar member is engaged with the engaging hole of the engaging piece to fix the frame. This eliminates the need for lifting the body and tightening the screws, so that the frame housing can be easily fixed without being damaged or overturned, and can be easily moved during maintenance.
