DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. This example is an example applied to a business monitor.

In the figure, 1 is a monitor for business use, and 2 is a monitor.
Is the screen. A pair of leg members 4F and 4R made of plastic or the like are fixed to the front and rear of the chassis 3 as the mounting surface of the bottom surface of the monitor 1, and the leg members 4F and 4F are attached to the front side of the chassis 3 of the monitor 1. Brackets 5 and 5 are fixed by using screws 6 and 6 in the vicinity of. By the brackets 5 and 5, locking portions 7a, 7a of the stand 7 which will be described later are pressed against the chassis 3 side, whereby the stand 7 is rotatably attached to the chassis 3.

FIG. 2 shows the structure of the bracket 5 on the left side. FIG. 2B is a plan view and FIG. 2A is a left side view thereof.
The bracket 5 includes a pressing portion 5a having a substantially U-shaped cross section, and a flat plate-shaped fixing portion 5b connected to one end side of the pressing portion 5a. The pressing portion 5a is formed in a partially notched state, and has an abutting portion 5d for restricting rotation of the stand 7 as described later. A screw 6 is provided in the center of the fixed portion 5b.
Insertion hole 5c is formed.

Further, the wall portion 5a2 on the opposite side is formed to be higher than the wall portion 5a1 on the side where the fixing portion 5b of the pressing portion 5a is connected, and a regulating piece extending outward at the end of the wall portion 5a2. 5a3 is formed. Although detailed description is omitted, the right bracket 5 is formed symmetrically with the left bracket 5 described above. This bracket 5 is, for example, iron, scan Te Nresu, is formed with other spring members.

FIG. 3 shows the structure of the stand 7. 1A is a plan view, FIG. 1B is a sectional view taken along the line I-I, and FIG. 1C is a sectional view taken along the line II-II. The stand 7 is formed in a substantially U-shape, and locking portions 7a extending outward are formed at both left and right ends. The stand 7 is formed by bending a bar material having a circular cross section as a whole.
Flat cut surfaces 7a1 and 7a2 are formed on 7a. The cut surface 7a1 is formed so as to be parallel to the surface of the chassis 3, that is, the stand 7 when the stand 7 is in the closed rotation position. The cut surface 7a2 is formed so as to be parallel to the surface of the chassis 3 when the stand 7 is in the open rotation position, and is formed at an angle of 80 ° with the cut surface 7a1. A rubber member 8 for slip prevention is wound around the ground portion 7b of the stand 7. The stand 7 is made of iron,
It is made of stainless steel or the like.

The procedure for attaching the stand 7 to the chassis 3 of the monitor 1 is as follows. First, although not described above, the restriction piece 5a3 of the bracket 5 is positioned on the opposite surface of the chassis 3 through the rectangular opening 11 formed in the chassis 3. Next, the locking portion 7a of the stand 7 is inserted into the pressing portion 5a of the bracket 5. Next, the screw 6 is inserted through the insertion hole 5c of the fixing portion 5b of the bracket 5 to fix the fixing portion 5a to the chassis 3. FIG. 4 shows the mounting portion of the stand 7 by the left and right brackets 5.

FIG. 5 shows the mounting portion of the stand 7 by the left bracket 5. And, FIG. 6 shows I of FIG.
The II-III line sectional view is shown. In the figure, 10
Is a washer, and 12 is a nut embedded in the chassis 3. The screw 6 is the insertion hole 5 of the fixing portion 5b of the bracket 5.
It is inserted into c and further inserted into the insertion hole 3a formed in the chassis 3 and screwed into the nut 12 as described above.

FIG. 6 shows the stand 7 in a closed state. In this state, the cut surface 7a1 of the locking portion 7a is pressed against the chassis 3 side by the pressing portion 5a of the bracket 5, and the locking portion 7a is pressed against the chassis 3. Then, the cut surface 7a1 of the locking portion 7a becomes parallel to the surface of the chassis 3,
The stand 7 is in a stable locked state.

Next, when the stand 7 is changed from the closed state to the open state, the ground portion 7b of the stand 7 is held and rotated in the counterclockwise direction. During the movement, as shown in FIG. 7, the engagement portion 7a of the stand 7 resists the pressing force of the bracket 5 on the chassis 3 side and the bracket 5 moves the bracket 5 to the chassis 3 side.
It is in a state of being pushed back in the direction of further separating. As described above, since the gap 5 is formed between the restricting piece 5a3 of the bracket 5 and the chassis 3 in the closed state, this push-back operation is performed smoothly.

When the stand 7 is further rotated, the stand 7 is opened as shown in FIG. In this state, the locking portion 7
The cut surface 7a2 of a is pressed to the chassis 3 side by the pressing portion 5a of the bracket 5, and the locking portion 7a is pressed to the chassis 3. Then, the cut surface 7a2 of the locking portion 7a becomes parallel to the surface of the chassis 3, and the stand 7 is in a stable locked state.

In this open state, the stand 7 comes into contact with the abutting portion 5d of the bracket 5, so that the rotation of the stand 7 is restricted even if a load is applied to the stand 7. Even in this open state, there is a gap d between the restriction piece 5a3 of the bracket 5 and the chassis 3. Also,
In this open state, the angle formed by the line orthogonal to the chassis 3 and the stand 7 is 10 °.

When changing from the open state to the closed state, the operation is the reverse of the above-described change from the closed state to the open state.

As described above, in this embodiment, when the stand 7 is changed from the closed state to the open state or from the open state to the closed state, the stand 7 can be easily rotated by holding the ground portion 7. You can In this case, the bracket 5 is deformed during the movement, but it is not necessary to deform the stand 7 itself. Therefore, stand 7
Can be made thicker than the conventional one,
The structure can withstand a heavy load. Therefore, for example, even if a load is accidentally applied to the top surface of the monitor 1, the stand 7 is not damaged, and the stand 7 can be used as a handle.

In the above embodiment, the stand 7 is used.
Although the two cut surfaces 7a1 and 7a2 are formed on the locking portion 7a of the above so as to be locked at the two-step rotational positions, the number of cut surfaces is increased to lock at the three-step or more rotational positions. It can also be configured to. This allows
It is possible to adjust the angle of the screen 2 of the monitor 1 in multiple stages.

Further, in the above-mentioned embodiment, the example in which the stand 7 is attached to the monitor 1 has been shown, but the present invention can be well applied when the stand is attached to other equipment.
