BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a display supporting device which is particularly effective when installed in a narrow space such as a vehicle interior.

[0002]

2. Description of the Related Art Conventionally, a display such as a small television set installed in a narrow space such as a vehicle compartment is generally fixed on a support base or has a directivity on the support base so as to have directionality. Is installed in.

[0003]

However, according to the configuration in which the display is installed on the support base via a tongue table or the like in order to have the directivity, the image plane is displayed with the center in the width direction of the display as a fulcrum. Since the configuration is oriented in the left-right direction, the left-to-right corner position of the rear surface of the display casing when the image surface is oriented in the left-to-right direction is
When the image surface is directed to the front, it moves backward from the rear position, so when the back surface of the display housing is installed close to a wall surface etc. due to the installation space, the directionality of the image surface is sufficient. There is an inconvenience that it cannot be taken, and this inconvenience becomes more prominent as the width of the display casing increases.

[0004]

In view of the above, the present application discloses a mounting board having a support shaft at left and right positions so that sufficient directivity can be obtained even when the width of the display housing is large.

Second springs for elastically biasing the pair of control plates in opposite lateral movement directions are connected to the support substrate so as to be laterally movable in the lateral direction, and the pair of control plates are respectively coupled to the second spring. And an actuating plate that can be laterally operated in the direction opposite to the spring, and the control plate has a control groove that bends in a dogleg shape and extends in the front-rear direction that engages with one of the corresponding support shafts. Having, and in the normal state, the support shaft is engaged with the front end positions of the side guide groove and the control groove, and from this normal state, by the operating plate,
By laterally moving either one of the left and right control plates in the direction against the second spring to allow the forward movement of one of the support substrates, the support substrate is supported with the other support shaft as a fulcrum.
It is characterized in that the casing is rotated horizontally by the elastic force of the first spring to direct the casing to either leftward or rightward. In the above, a pair of left and right control plates are provided in order to match the lateral movement direction of the operating plate and the left-right direction of the display casing for convenience of use.
Each of the pair of left and right control plates has a locking step portion, and the locking step portion of the left control plate is located on the right side and the locking step portion of the right control plate is on the left side. The parts are overlapped with each other and arranged laterally movably on the support substrate, and locking pieces are respectively provided at the left and right positions of the operating plate to respectively lock with the locking step portions facing the left and right. Further, in order to change the direction of the display casing in a stepwise manner, a plurality of control grooves are continuously provided in the front-rear direction within the length of the side guide groove.
Also, so that you can easily adjust the image surface of the display,
With respect to the support substrate, the housing of the display is provided with adjusting means for adjusting upward and downward, the adjusting means is provided upright on the left and right side edges of the supporting substrate, respectively.
A left and right support piece having a through hole at the upper end, a screw hole provided on the side surface of the casing of the display facing the through hole, and a tightening knob having a screw shaft screwed into the screw hole projecting from the inner surface. It consists of and. Further, in order to simplify the structure, a means for laterally movably connecting the pair of left and right control plates and the operating plate to the support substrate is provided with a pair of left and right support pins provided on the support substrate, the control plate, It is composed of a pair of left and right elongated holes that engage with the support pins respectively provided on the operation plates, and furthermore, in order to improve the appearance, a concave portion is provided on the lower surface of the display casing.

It is formed by projecting forward from the recess.

[0005]

However, in the stationary state in which the display casing is oriented to the front, the left and right side guide grooves and the front ends of the control holes are engaged with the left and right support shafts provided on the mounting board, respectively. By this engagement, the support substrate is prevented from moving forward against the elastic force and the actuation plate is placed in the neutral position. In order to direct the housing from this stationary state to either the rightward or leftward direction, the actuating plate is actuated by the lever in either direction, for example, to the right. Then, the left control plate laterally moves against the spring, and the lateral movement disengages the front end of the control groove at the left position from the support shaft at the left position, allowing the support substrate to move forward at the left position. In the right position, the support shaft in the left position guides the control groove and the side guide groove in the left position, and in the right position, the front ends of the control groove and the side guide groove are engaged with the support shaft. As a result, the support substrate rotates forward with the support shaft in the right position as a fulcrum due to the elastic force applied to the support substrate, and this rotation causes the support shaft in the left position to engage with the rear end of the control groove. Stop when you do. That is, the support substrate is rotated rightward corresponding to the distance between the front and rear ends of one control groove, and the display housing is oriented rightward.

In the above, when the display casing is returned to the stationary state from the state in which it is oriented rightward, the front left side portion of the display casing is pushed backward.
Then, the support shaft at the left position comes out of the rear end of the control groove at the left position and guides the side guide groove at the left position and the control groove at the left position, respectively. Therefore, the support force is applied by the pressing force applied to the display housing. The base plate rotates rearward with the support shaft in the right position as a fulcrum, and returns to the stationary state when the support shaft in the left position engages with the front ends of the control groove and the side guide groove in the left position, respectively.

The above-described operation is substantially the same except that the left-right positional relationship is symmetrical even when the housing is oriented leftward from the stationary state. That is, when the operating plate is moved to the left from the stationary state and the control plate at the right position is moved laterally to the left side against the spring, the support shaft at the right position becomes the control groove at the right position and the side guide groove at the right position. At the left position, the front end of the control groove and the side guide groove is engaged with the support shaft, and the support substrate is The front urging force acts on the support shaft in the left position to rotate it backward, and this rotation stops when the support shaft in the right position engages with the rear end of the control groove. Point to the left.

When the display casing is returned to the stationary state from the left-oriented state, the front right side portion of the display casing is pushed rearward. Then,
The support shaft in the right position comes out of the rear end of the control groove in the right position and guides both the side guide groove in the right position and the control groove in the right position, so that the pressing force applied to the display housing causes the supporting substrate to move to the right. When the support shaft in the position engages with the front ends of the control groove and the side guide groove in the right position, the shaft returns to the stationary state.

Further, in the above, when the plurality of control grooves are continuously provided in the front-rear direction, the horizontal direction of the display housing can be gradually increased.
