Description

Detailed Description of the Invention

[0001]

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 rear 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.
In a stationary state in which the casing of the display is supported, the left and right positions are guided by the support shafts, respectively, and the casing can be moved forward and backward, and is always biased forward by the forward direction, and the casing is oriented to the front. , The forward movement is blocked against the biasing force, and when the lever is operated in either of the relative directions from this state, the forward movement is unblocked in either of the two directions, and either of the other support shafts is released. The fulcrum is constituted by an actuating mechanism arranged on the mounting substrate which is pivoted by a front biasing force to serve as a fulcrum and directs the housing to either leftward or rightward. Specifically, the actuating mechanism is mounted on the mounting board so as to be movable back and forth by a pair of left and right outer guide grooves extending in the front-rear direction which are engaged with support shafts provided at left and right positions on the mounting board, respectively. , A support substrate that always supports a display casing that is elastically biased forward, and a support substrate that is laterally movably disposed on the support substrate and that is elastically pressed outward by springs. A pair of left and right control plates provided with at least one control groove that is bent inward at the outer end portion and that engages with the one support shaft to prevent forward movement of the support substrate, and a lever, The pair of left and right control plates are selectively moved laterally in the outward direction against the springs, and an actuating plate that allows the supporting substrate to move forward on the side of the laterally moved control plates. In the above, in order to match the operation direction of the lever and the direction of the housing of the display for convenience of use, a locking step portion is provided at an intermediate position between the pair of left and right control plates, and the control plate at the left position is provided. The locking step of is on the right side,
A part of a pair of left and right control plates is overlapped so that the locking step of the control plate at the right position is located on the left side, and is laterally movably arranged on the supporting substrate. And a locking piece that locks with the locking step facing each other. In addition, multiple control grooves are provided continuously in the front-rear direction so that the orientation of the display housing can be changed stepwise, and the display housing can be adjusted relative to the support substrate so that the image surface of the display can be easily adjusted. Is supported by adjusting means so that the vertical direction can be adjusted, and the adjusting means is provided upright on the left and right side edges of the support substrate, and the left and right support pieces having through holes at the upper end, The screw shaft is screwed into a screw hole provided on the side surface of the display case through the through hole, and a tightening knob is provided on the inner surface of the screw shaft. Further, in order to simplify the configuration, a pair of left and right control plates and an actuating plate are attached to the supporting substrate by guide means so as to be able to move laterally, and the guiding means includes a pair of left and right supporting pins provided on the supporting substrate. , The control plate and the actuating plate that engage with this are respectively composed of a pair of left and right elongated holes, and in order to further improve the appearance, a concave portion is provided on the lower surface of the display casing. Between the mounting board and the mounting board, the supporting board, the pair of left and right control plates, and the operating plate are respectively interposed,
The lever projecting from the front edge of the actuating plate is projected forward from a notch recess provided in the front surface of 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.
