BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base having a moving mechanism, and more particularly, to a mounting base capable of sliding in all directions and rotating about a specific point. .

[0002]

2. Description of the Related Art Conventionally, as a mounting table for mounting a television, a rack and the like, a moving mechanism such as a caster is provided at a lower portion,
2. Description of the Related Art There is known a device having a rotation mechanism capable of rotating a television, racks, and the like mounted on an upper portion.

FIG. 6 is a view for explaining an example of a conventional television mounting base with casters. FIG. 6A is a conceptual view showing a part of the television mounting base in a cross-section, as viewed from the front. 6B is a cross-sectional view taken along line BB of FIG. 6A, FIG. 6C is a cross-sectional view taken along line CC of FIG. 6A, and FIG. Is a view of the TV mounting base of FIG. 6 (A) viewed from the bottom, in which 4 is the TV mounting base, 41 is a cabinet part, 42 is a trolley plate, and 43 is a rotatable cabinet part 41 and a trolley plate 42. , A caster 44 and a caster fixing plate 45 for fixing the caster 44. A rotating mechanism 43 is formed by providing a bearing between the cabinet portion 41 and the bogie plate 42, and the cabinet portion 41 is rotatable with respect to the bogie plate 42 via the bearing.

[0004] The television mount can be slid to any desired position by the casters 44, and after being moved to any desired position, the fixed plate 45 is used as described above. Alternatively, it is fixed by a lock mechanism provided on the caster, and the cabinet 41 is rotated with respect to the bogie plate 42 in the fixed state.

[0006]

As described above, a mounting table having a moving mechanism according to the prior art requires a caster for moving the mounting table and a rotating mechanism different from the caster for rotating the mounting table. However, there was a drawback that it became complicated. Further, the cabinet part 41 is connected to a trolley plate 42.
If the casters 44 for movement are attached when rotating with respect to, the bogie plate 42 moves when the cabinet is rotated unless the casters 44 are fixed, and the rotation of the cabinet portion 41 does not go smoothly. A caster with a lock, a caster fixing plate 45 as shown, and the like are required. For casters with locks, it is expensive, and it is difficult to lock because the lock lever does not know where to move when moving the base, and a certain distance from the floor is required when locking There was a drawback that the casters were too visible from the front and the appearance was not good. When a fixed plate is laid, there is a drawback that if a heavy object is placed on the mounting table at the time of mounting when the fixed plate is laid, it is very dangerous, and the usability is poor. Since the cabinet part 41 is attached to the mounting base (trolley plate 42) by the single rotation mechanism 43, the cabinet part 41 swings when it is moved by the casters, and has a disadvantage that it is unstable and hard to move.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and can reduce the number of parts to make the structure inexpensive, and can stably support the mounting table during movement and rotation. It is an object of the present invention to provide an easy-to-use mounting table.

[0008]

According to the present invention, as a means for solving the problems in the prior art as described above, a caster serving as a moving mechanism is used as it is as a rotating mechanism for rotating a mounting table. It is an object of the present invention to provide a mounting base with casters that is inexpensive and that can stably rotate the mounting base.

According to a first aspect of the present invention, in a mounting table having a moving mechanism capable of sliding in any direction with respect to the floor, the sliding movement is suppressed and the mounting table is fixed to the floor. A fixing mechanism, the fixing mechanism includes a floor contact member capable of contacting a floor surface, and an elevating member to which the floor contact member is rotatably attached at a lower end portion. When the floor contact member is pressed down and fixed to the floor surface by descending, the mounting table is rotatable around the floor contact member with respect to the floor surface.

According to a second aspect of the present invention, in the first aspect, the moving mechanism is mounted on a bottom of the mounting table.
It is characterized by being at least one caster.

According to a third aspect of the present invention, in the second aspect of the present invention, the three or more casters are provided on the same circumference around the fixing mechanism.

FIG. 1A is a conceptual view showing a part of the television mounting base in a cross-section, as viewed from the front, and FIG. 1B is a BB view of FIG.
FIG. 1C is a cross-sectional view as viewed from the line direction, and FIG.
FIG. 1D is a cross-sectional view taken along the line C, and FIG. 1D is a view of the TV mounting base of FIG. 1A viewed from the bottom. Casters that can be moved, 12 is the bottom plate of the TV mount,
Reference numeral 13 denotes a fixing mechanism capable of fixing the television mounting table 1 to the floor surface so as not to slide.

FIG. 2 is a view showing a state in which the television mounting base 1 is rotated. Based on a state I in which the front side is oriented, the state II is such that the front side of the television mounting base 1 faces rightward. When rotated in the direction A, the state III shows a state in which the television mounting table 1 is viewed from the bottom when the television mounting table 1 is rotated in the direction B so that the front of the television mounting table 1 faces left. In order to facilitate rotation, three or more casters may be mounted on the same circumference around the fixing mechanism 13, but in the present embodiment, the cabinet part 41 when the television mounting base 1 slides is moved. 4 casters 11 considering stability
Are mounted on the same circumference around the fixing mechanism 13.

FIG. 3 is a view for explaining the structure of the fixing mechanism 13 in FIG. 1. In FIG. 3, reference numeral 12 denotes a bottom plate of the television mounting base 1, reference numeral 21 denotes a lifting member (bolt), and reference numeral 22 denotes a bolt 2
A knob integrated with 1; 23, a drop plate having a hole passing through the bolt 21; 24, a bearing fixture fixed to the bolt 21; 25, a bearing ball for freely rotating the bearing fixture 24; Is a spring receiving plate rotatably attached to the bearing fixing bracket 24, 27 is a rotating part storage box, 28 is a spring, 29 is a screw member fixed to the bottom plate 12 and screwed to the bolt 21. In the drawing, reference numeral 30 denotes a rotating unit storage box 27.
Is a floor contact member (friction member) affixed to.

A procedure for fixing the television mounting base and rotating the television mounting base in both forward and reverse directions will be described. FIG. 3 shows a state in which the friction member 30 is separated from the floor surface. As an elevating mechanism, a bolt 21 and a nut 29 are installed on the bottom plate 12, and the bolt 21 is rotated clockwise by hand or coin. , The bolt 21 is going down.

FIG. 4 is a view showing a state in which the friction member 30 is in contact with the floor in FIG. 3. When the knob 22 is further rotated clockwise from the state in FIG. 3, the friction member 30 comes into contact with the floor surface.

FIG. 5 is a view showing a state in which the friction member 30 is pressed and fixed to the floor surface in FIG. After the friction member 30 comes into contact with the floor surface, the bolt 21 is further rotated clockwise to push down the spring receiving plate 26 through the bearing fixing bracket 24 to reduce the spring 28 while lowering the knob 22 so that the lower surface 22a of the knob 22 is mounted on the television. The fixing is completed by contacting the stop surface 12a of the base plate 12. At this time, an arbitrary load is applied to the floor surface by a spring load, and even if a force for moving the table is applied, sliding movement cannot be performed due to friction with the floor. On the other hand, the friction member 30 is pressed against the floor surface,
In addition, since it can rotate freely with respect to the television mounting base plate 12, when a force for moving the base is applied, the caster 11 moves to rotate in both the forward and reverse directions about the center axis L of the fixing mechanism 13. Exercise becomes possible. Conversely, by rotating the bolt 21 counterclockwise, the friction member 3
0 moves away from the floor, and the television mount 1 can be slid.

In this embodiment, the bolt 21 and the nut 29 are used as the elevating member so that the pressure contact force on the floor can be adjusted. In addition, for example, instead of the bolt, a projection is provided on the side surface. The cylindrical member, in place of the nut, has a vertical groove that engages with the protrusion, and a groove that engages so as to be able to rotate in the radial direction when the cylindrical member is pushed down,
By pushing down the cylindrical member and rotating in the radial direction, by hooking the protrusion in the radial groove,
A mechanism for stopping the floor surface in pressure contact may be used.
