Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt base provided in a display device or the like.

2. Description of the Related Art Conventionally, a tilting table, that is, a table which allows a main body to be rotated laterally or tilted up and down is often used for a display device or the like. FIG. 16 shows an example of this tilt base. In FIG. 16, reference numeral 21 denotes a curved surface member on which an object (not shown) such as a display device main body is placed, 22
Is a support member that supports the curved member. The support member 22 is provided with an annular pedestal 22a on the outer peripheral portion, and the pedestal 22a and the curved surface member 21 slide. By sliding the curved surface member 21 on the pedestal 22a, it becomes possible for the mounted object to make a rotational movement in a lateral direction and a tilting movement, that is, a movement inclining vertically.

Reference numeral 23 denotes a protrusion that is provided at the center of the support member 22,
A flange 24 is formed at the tip of the protrusion 23 to keep the engagement with the curved member 21 and prevent the support member 22 from falling off. On the other hand, a slit 25 is formed in the curved member 21 so that the tilt motion can be performed while the protruding portion 23 is penetrating. The width of the slit 25 is narrower than the width of the collar 24. Therefore, when the curved member 21 is attached to the support member 22, the collar portion 24 does not come off from the slit 25, and the curved portion 21 is supported by supporting the collar portion 24 on the back side of the curved member 21.
The detachment of the support member 22 from the support member 22 is prevented. Again slit 25
An insertion opening 26 through which the collar portion 24 can pass is formed at the end portion thereof only at a specific angle.

When attaching the curved surface member 21 to the support member 22, first, the protruding portion
23 is inserted through the insertion opening 26. And the curved member 21 is 180
° rotated. When the curved member 21 is thus rotated by 180 °, the flange portion 24 does not come off from the insertion opening 26. Next, a force is applied to the curved surface member 21 to cause a tilt movement, and the flange portion 24 is moved toward the slit 25.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the configuration as described above, the collar portion 24 has the insertion opening
The curved member 21 can freely rotate over 360 degrees while being located at the position. And the collar 24
When the angle between the insert and the insertion slot 26 reaches a certain angle, the collar 24
Is separated from the insertion opening 26, and the curved surface member 21 and the support member 22 are easily separated. Then, for example, when the curved surface member and the support member happen to be at the above-described specific angle when the display body is lifted, only the support member 22 will fall apart.

It is also conceivable that the protrusion and the flange provided at the tip of the protrusion are formed as separate members, and the protrusion is passed through the curved member before the flange is attached. With this structure, the collar portion can be made sufficiently large, so that the above-mentioned problem does not occur. However, if the collars are formed in different pairs, the number of parts will increase accordingly, and the number of man-hours will increase at the time of mounting. In addition, since the collar portion needs to be attached, the curved member and the object to be placed must be separated from each other.

The present invention has been made in view of this problem, and an object thereof is to provide a tilt base in which the curved member and the supporting member are not easily separated from each other.

Means for Solving the Problems In order to solve the above problems, the present invention provides two protrusions on a curved surface member, and a support member outer peripheral portion is provided with an abutting portion whose both sides can abut the above protrusion, It is configured such that the abutting portion is located on the track of the protrusion when the curved member is rotated with the protrusion on the supporting member side being positioned at the insertion port of the curved member. When the curved member is rotated while being displaced from the insertion opening, the abutting portion is disengaged from the trajectory of the protrusion so that the abutting portion does not contact the abutting portion, and the abutting portion is positioned between the protrusions. The angle between the curved surface member and the supporting member when being set is such that the flange portion can be removed from the insertion opening.

With the above configuration, even if the curved member is rotated with the protruding portion positioned at the insertion opening,
Rotation is hindered by hitting one of the protrusions on the abutting portion on the supporting member side, and the abutting portion does not come between the both protrusions. On the other hand, when the projection is displaced from the insertion opening and the projection is located at the insertion opening after being aligned with a specific rotation position, the abutting portion is formed on both projections. , And at that time, the collar portion can be removed from the insertion opening.

Embodiments Embodiments of the tilt base according to the present invention will be described below. FIG. 1 is an exploded perspective view of a tilt base in the present embodiment. In FIG. 1, reference numeral 1 is a curved surface member, which is mounted on the bottom of an object (not shown) such as a display device body. Reference numeral 2 is a supporting member that receives the curved member, and is provided with an annular receiving base 2a on the outer peripheral portion. Reference numeral 5 denotes a projecting portion projectingly provided in the central portion of the supporting member 2, and a flange portion 3 for preventing engagement of the supporting member 2 with the tip portion of the projecting portion 5 while keeping engagement with the curved member, 4 are formed. On the other hand, a slit 6 is formed in the curved member 1 so that the protrusion 5 can move in a penetrating state, and an insertion port 7 through which the collar portions 3 and 4 can pass is formed at an end of the slit 6. . The protrusion 5 is inserted through the insertion port 7. Then, by applying a force to the curved surface member 1 to perform a tilting movement, the protruding portion 5 moves along the slit 6. Then, in the slit portion, the sides 6a and 6b on both sides prevent the flange portion from coming off. Further, the flange portions 3 and 4 can pass through the insertion opening 7 only when the curved member 1 makes a certain angle with the support member 2.

Denoted at 8 and 9 are projections provided on the curved member 1 so as to sandwich the slit 6. Reference numeral 10 is an abutting portion projecting from the supporting member. The width of the contact portion 10 is large enough to fit between the protrusion 8 and the protrusion 9. The contact portion 10 is arranged inside the pedestal 2a.

The mounting method will be described below. First, the angle between the curved member 1 and the support member 2 is adjusted to the angle at which the collar portions 3 and 4 can pass through the insertion opening 7, and the protrusion 5 is inserted into the insertion opening 7 as shown in FIG. The curved member 1 and the supporting member 2 are angled at this time.
When they are fitted together, as shown in FIG. 3, the contact portion 10 is inserted between the projection 8 and the projection 9 on the curved surface member 1 side.

Next, from this state, as shown in FIG. 4, a tilt movement is performed in the direction of arrow A. At that time, the projecting portion 5 moves along the slit 6 and comes to the end portion on the opposite side to the insertion port 7, resulting in the state shown in FIGS. 5 and 6. When the protrusion 5 moves a little along the slit 6, the flanges 3 and 4 of the protrusion 5 come to engage with the sides 6a and 6b on both sides of the slit 6, and therefore the flanges 3 and 4 are detached. do not do.

Next, as shown in FIG. 6, it is rotated about 180 ° in the direction of arrow B. Then, it becomes as shown in FIG.

This completes the work of attaching the curved member 1 to the support member 2. When changing the orientation of the display device during normal use, as shown in FIG. 7, a tilt movement is made in the arrow C direction, and a rotation movement is made in the arrow D direction.

Further, when the curved member 1 and the support member 2 are separated, the above-described work for mounting may be performed in reverse.

With the above configuration, even if the curved surface member 1 is rotated with the protruding portion 5 located at the insertion opening 7 as shown in FIG. Does not separate, and even if the curved surface member 1 is rotated in this state, either the protrusion 8 or the protrusion 9 abuts on the abutting portion 10 so that the rotation is hindered on the way, and the abutting portion 10 is Protrusion
It never comes between 8 and 9. Therefore, the protruding portion 5 does not reach the angle at which it separates from the insertion opening 7, and the curved surface member 1 and the support member 2 do not separate.

However, when the curved member 1 and the support member 2 make a certain angle, the protruding portion 5 can be positioned at the insertion port 7 by tilting the curved member 1 and the support member 2, and the collar portions 3 and 4 are inserted into the insertion port 7.
It is possible to get out of. That is, when the state shown in FIG. 6 is set in advance and the state is tilted in the direction of arrow H from this state to the state shown in FIG. 3,
The curved surface member 1 and the supporting member 2 are separated from each other. In addition,
At this time, the contact portion 10 enters between the protrusion 8 and the protrusion 9.

Next, a second embodiment improved from the above embodiment will be described. FIG. 9 shows a support member for receiving a curved member, and in FIG. 9, 11 and 12 are rotation restricting portions projectingly provided under the projecting portion 5. The rotation restricting part 11 has an upper
As shown in the figure, the height is such that it can be inserted into the slit 6 with the protruding portion 5 inserted into the insertion opening 7. Also, the rotation restricting portion 12 on the back side thereof has the same height. And
By contacting the sides 6a and 6b on both sides of the slit 6 with the rotation restricting portions 11 and 12, the angle formed by the curved surface member 1 and the supporting member 2 is restricted.

Since the other parts of the support member and the other curved member are the same as those in the previous embodiment, the description thereof will be omitted.

 Next, the mounting method will be described.

First, the angle between the curved surface member 1 and the support member 2 is adjusted to the angle at which the collar portions 3 and 4 can pass through the insertion opening 7, and the protruding portion 5 is inserted into the insertion opening 7 as shown in FIG.

Next, from this state, as shown in FIG. 10, a tilt movement is made in the direction of arrow I. Then, the projecting portion 5 moves along the slit 6 and enters a state as shown in FIG. 11, so that the projecting portion 5 does not come off from the insertion port 7.

Next, as shown in FIG. 11, it is rotated about 45 ° in the direction of arrow J. Then, as shown in FIG. 12, the rotation restricting parts 11 and 12 have sides 6a,
It hits 6b and further rotation is restricted.

Next, as shown in FIG. 12, tilt movement is made in the direction of arrow K. Then, the protrusion 5 returns to the insertion opening 7 again. That is, as shown in FIG.

Next, as shown in FIG. 13, it is rotated in the direction of arrow L by about 135 °. Then, it becomes as shown in FIG. However, in these states, the protruding portion 5 does not separate from the insertion opening 7.

The work for attaching the curved surface member 1 to the support member 2 is thus completed. Figure 15 shows the protrusions 8,
It shows the movement of the protrusion 9 of the 9.

By the way, when the curved member 1 is rotated in a state in which the protrusion 5 is located at the slit 6 as shown in FIG. 11 and FIG.
11 (12) is regulated between where the slit 6 contacts one side 6a (6b) and where the other side 6b (6a) contacts. However, as shown in FIG. 13 and FIG. 14, in the state where the protrusion 5 is located at the insertion port 7, the curved surface member 1
The rotation restricting portion 11 (12) does not come into contact with the sides 6a and 6b when the is rotated. However, the curved surface member 1 is not freely rotatable over 360 °, and in this case, as in the case of the previous embodiment, either the protrusion 8 or the protrusion 9 contacts the contact portion 10 to prevent rotation. Regulated.

Therefore, whether the protruding portion 5 is located at the slit 6 or at the insertion opening 7, the protruding portion 5 will be inserted when the curved member 1 is rotated. The angle at which the curved surface member 1 and the supporting member 2 are separated from each other is never reached, and the curved surface member 1 and the support member 2 are not separated from each other.

When the curved surface member 1 and the support member 2 are separated, the above-described work for mounting may be performed in reverse.

EFFECTS OF THE INVENTION As described above, according to the present invention, the curved member is provided with the two protrusions, the support member is provided with the abutment portion that can be inserted between the two protrusions, and the protruding portion on the support member side is provided with the curved member. It is configured such that the abutting portion is located on the trajectory of the protrusion when the curved member is rotated at the position of the insertion opening, and the protruding portion is displaced from the insertion opening to form the curved member. When rotating, the abutting portion is disengaged from the trajectory of the protrusion so that the abutting portion does not contact the abutting portion, and the curved member and the curved member when the abutting portion is positioned between the protrusions Since the angle with the support member is such that the collar portion can be detached from the insertion opening, even if the curved member is rotated with the protruding portion located at the insertion opening, Make sure that one of the two protrusions touches the protrusion on the support member side. Te rotation is restricted, that the abutment portion comes between both projections is not, the flange portion is never detached from the insertion opening. Then, the angle formed between the curved member and the support member is set to a certain specific angle, and then the tilting movement is performed to position the protruding portion at the insertion opening so that the collar portion is separated from the insertion opening. Become. In other words, no matter how much the curved surface member is rotated, the collar portion does not separate from the insertion hole during the rotational movement as in the conventional case, only when the protruding portion is located at the insertion opening. The curved member and the support member will not be easily separated.
