Description

  The present invention relates to a monitor stand for installing a monitor on an installation surface, in particular, a monitor that is retrofitted on an installation surface such as a dashboard of a vehicle from the driver's or passenger's seat side while ensuring driving visibility. It is related with the monitor stand which was attached so that adjustment was possible in the position where it is easy to see from the most.

  As a display unit of a car navigation system, a thin monitor composed of a liquid crystal display device or the like may be retrofitted on a dashboard in front of a driver's seat. When installing, if the monitor protrudes greatly on the dashboard, it will hinder the driver's view.

  In addition, it is inconvenient if the installation position of the monitor fluctuates due to the movement of the monitor stand due to the vibration of the vehicle, so that a support structure having a particularly high posture holding force is required.

  In order to solve these problems, in the utility model registration document 1 below, the holding part to which the monitor is attached can be held at a desired horizontal rotation angle with respect to the base part attached to the installation surface, and can be locked as necessary. A mechanism that is locked by a mechanism has been proposed.

According to the monitor stand of this structure, the monitor mounted on the dashboard or the like can be tilted horizontally as necessary to secure the field of view, and the degree of freedom of the horizontal installation angle of the monitor is high. However, this structure has the following technical problems.
JP 2005-75175 A

  According to this structure, it is possible to adjust only the two directions of the horizontal turning and the inversion of the monitor. When the monitor is to be viewed, it must be stood on the dashboard, which hinders the field of view. Conversely, if the monitor is tilted horizontally to ensure visibility, the monitor will be difficult to see.

  Of course, while driving, looking at the monitor or standing up is dangerous from the aspect of driving operation, the monitor continues to display the road map image based on GPS information in any posture. Therefore, it is troublesome from the viewpoint of operation to set up or defeat each time the vehicle is stopped or started.

  The present invention solves the above-mentioned problems. The purpose of the present invention is to secure the driver's field of view while holding the monitor fixedly at the most visible position from the driver's or passenger's side. It is intended to provide a monitor stand having a high posture holding power that can be easily adjusted in the case of a position change or the like.

In order to achieve the object, the monitor stand according to claim 1 is a monitor stand for installing a monitor on an installation surface.
A mounting substrate fixed to the installation surface;
A disk-shaped fixing block fixed on the mounting substrate;
A pair of swivel blocks that are halved and fitted on the outer periphery of the fixed block so that they can swivel;
A support arm rotatably held between the swivel blocks;
The shaft hole formed at the pivot center of the support arm and the shaft hole formed in the pivot block are provided through and are releasably tightened so that the pivot position of the pivot block and the tilt position of the support arm are predetermined. A fixed handle for fixing to the position of
A monitor mounting block that is pivotably fitted to the tip of the support arm and attaches the monitor;
Fixing means for fixing the inclined position of the monitor mounting block to a predetermined position by penetrating through a shaft hole formed at the tip of the support arm and the center of rotation of the monitor mounting block and releasably tightening And
The monitor is installed on the installation surface so that at least a part of the monitor is positioned below the installation surface.

The monitor stand according to claim 2 is the monitor stand according to claim 1,
Spline grooves that engage with each other are formed on the outer periphery of the fixed block and the periphery of the mounting hole formed on the inner side of the fitting portion of the swivel block.

The monitor stand according to claim 3 is the monitor stand according to claim 1,
Radial spline grooves that engage with each other are formed around the inner periphery of the shaft hole formed in each swivel block and the outer periphery of the shaft hole of the support arm.

The monitor stand according to claim 4 is the monitor stand according to claim 1,
A radial spline groove is formed on the inner periphery of the shaft hole formed at the tip of the support arm and on the outer periphery of the shaft hole of the monitor mounting block.

  The monitor stand according to claim 5 is the monitor stand according to claim 1, wherein an arc-shaped recess for guiding a rotating portion of the support arm is formed on an upper surface of the fixed block. It is said.

  In the first aspect of the invention, since there are three degrees of freedom such as the turning angle, the vertical height, and the mounting angle of the monitor, it is possible to take an arrangement in which at least a part of the monitor is positioned below the installation surface. It is possible to secure a driver view above the installation surface. At the same time, the monitor can be fixedly and stably held in a posture that is most easily seen from the driver's or passenger's side.

  According to the second aspect of the invention, the horizontal turning position of the turning block can be adjusted and fixed by a fixed handle operation. When tightened, the spline grooves are engaged with each other, so that the adjusted position of the turning block in the turning direction can be reliably held by a simple operation.

  According to the third aspect of the present invention, the tilt angle of the support arm can be adjusted and fixed by the tightening operation of the fixed handle. When tightened, the spline grooves are engaged with each other, so that the adjusted inclination angle of the support arm can be reliably held by a simple operation.

  According to the fourth aspect of the present invention, the inclination angle of the monitor mounting block can be adjusted by the operation of the fixing means, and the adjusted inclination angle of the monitor mounting block can be reliably held by a simple operation.

  According to the fifth aspect of the present invention, since the rotation portion of the support arm is guided by the arc-shaped recess on the upper surface of the fixed block, the rotation of the support arm is stable and the fixed handle is impossible. It is difficult to apply extra power.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS. 1A to 1C are a plan view, a side sectional view, and a front view of a monitor stand according to the present invention, FIG. 2 is a fully exploded perspective view of the monitor stand, and FIGS. 3A and 3B are the same. FIGS. 4A and 4B are perspective views showing before and after attaching the monitor stand to the monitor, and FIGS. 5A and 5B show the monitor. It is explanatory drawing which shows the relationship between the attachment position at the time of attaching to a passenger car and a visual field.

  1 to 3, the monitor stand 1 includes a mounting board 2, a fixing block 3 fixed on the mounting board 2, and a halved turning block 4 fitted so as to be able to turn around the fixing block 3. A support arm 5 rotatably held inside the upper part of the swivel block 4, a monitor mounting block 6 fitted rotatably inside the front end of the support arm 5, and these members are assembled. For example, each of the main parts 3, 4, 5 and 6 excluding the mounting board 2 is made of an ABS / PC super heat-resistant resin molded body.

  The mounting substrate 2 is made of a thin steel plate, blank-cut into a shape obtained by cutting an ellipse by press molding, and a dish-shaped mounting seat surface 7 is projected from the center of the end near the straight portion. A plurality of slits 8 are radially punched from the periphery of the seat surface 7 and each slit 8 ensures deformation conformability along the curved surface of the installation surface such as a dashboard.

  Further, a double-sided strong adhesive tape 9 covered with release paper or the like is fixed to the lower surface of the mounting substrate 2. When fixing to the installation surface, the release paper is peeled off and along the curved surface of the installation surface via the adhesive tape 9. It is designed to be firmly fixed while being deformed.

  The fixed block 3 is fixed to the seat surface 7 through a plurality of screws 10 and has an upper portion having a large diameter, and an upper surface of the fixed block 3 having an arc shape for guiding a rotating portion of the support arm 5. Are formed with a spline groove 11 at a predetermined pitch.

  Each of the swivel blocks 4 is formed with a concave groove 12 fitted to the outer periphery of the fixed block 3 on the lower inner side, and a notch wall 13 for holding the support arm 5 on the upper inner side. The support arm 5 is sandwiched between the notch walls 31 and is formed in an outer shape that forms a substantially oval curved surface. And the spline groove | channel 14 which meshes with the said spline groove | channel 11 is carved in the inner back part of the said concave groove | channel 12 with the same pitch.

  A mounting hole 15 is formed in the upper portion of each swivel block 4. A bolt 16 serving as a rotation center axis is inserted through one of the mounting holes 15, and a washer 17 and a spring washer 18 are provided at the other projecting end. The fixed handle 19 is screwed through and tightened. The fixed handle 19 is formed by integrally insert-molding a nut to be screwed to the bolt 16 into the ABS / PC super heat resistant resin.

  A projecting portion 20 having a diameter larger than this is formed around the mounting hole 15 in the notch wall 13, and a radial spline groove 21 centering on the mounting hole 15 is formed on the surface of the projecting portion 20. It is engraved.

  A shaft hole 22 through which the bolt 16 is inserted is formed at the rotation center of the support arm 5, and the outer periphery of the center hole 22 of the support arm 5 is concentric with the shaft hole 22. A recess 23 having the same inner diameter as the protruding portion 20 is formed, and a radial spline groove 24 having the same pitch as the spline groove 21 around the rotation center hole is formed inside the recess 23.

  Therefore, in the state where the fixed handle 19 is loosened, the interval between the turning blocks 4 is widened, and the turning block 4 can turn around the fixed block 3 and the support arm 5 can turn. In this state, the turning block 4 4 is positioned at an arbitrary turning angle position, and the support arm 5 is positioned at an arbitrary inclination angle position, and then the fixed handle 19 is tightened, whereby the spline grooves 11 and 14 and the radial spline grooves 21 and 24 are connected to each other. And are fixed at the turning and tilting angle positions by a strong posture holding force.

  Furthermore, a pair of bracket portions 25 branched into two branches are integrally formed at the front end portion of the support arm 5, and each bracket portion 25 is formed with a shaft hole 26, and inside each bracket portion, A radial spline groove 27 centering around the shaft hole 26 is formed around the shaft hole 26.

  The monitor mounting block 6 includes a rotating block 28 that is rotatably fitted to the bracket portion 25, a flat mounting plate 29 that is vertically integrated with the tip of the rotating block 28, and a mounting plate 29. And a metal holding plate 31 connected by a round countersunk screw 30 inserted from the lower side rear surface of the mounting plate 29.

  A shaft hole 32 penetrating the rotation block 28 is formed at the rotation center of the rotation block 28, and the bracket portion 25 of the support arm 5 is formed around the shaft hole 32 around the shaft hole 32. Further, radial spline grooves 33 are formed at the same pitch as the spline grooves 27.

  Therefore, the radial spline grooves 27, 26, 32 pass through the shaft holes 26, 32 by inserting a round countersunk screw 34 with a hexagonal hole as a fixing means, and tightening a nut 35 as a fixing means arranged on the other end side. The monitor mounting block 6 can be fixed to the tip end of the support arm 5 at a predetermined inclination angle position by the meshing force 33 and the strong posture holding force.

  Next, a procedure for attaching the above monitor stand 1 to the monitor will be described with reference to FIG. As shown in FIG. 4A, it is assumed that a lower groove is opened at the center of the back surface of the monitor 50, and a dovetail mounting portion 51 whose upper portion is closed is fixed integrally or retrofitted.

  As this attachment procedure, first, as shown in FIG. 4 (a), only the monitor attachment block 6 is removed from the monitor stand 1, the screws 30 are loosened, and the interval between the attachment plate 29 and the holding plate 31 is widened. Then, the holding plate 31 is inserted from below the mounting portion 51, and the screw 30 is tightened at an appropriate position, so that the mounting portion 51 is interposed between the tightening plate 31 and the mounting block 6 via the groove in the mounting portion 51. Hold it in place.

  On the other hand, when the installation position of the mounting board 2 is determined, the release paper is peeled off, and the mounting board 2 is brought into close contact with the installation position via the adhesive tape 9, and then the mounting block 6 is connected via the screw 33 and the nut 44. By connecting to the support arm 5, connecting various wirings of the monitor 50 and turning on the power, the display image of the monitor 50 fixed by the monitor stand 1 can be seen as shown in FIG.

  FIG. 5 shows a state where the monitor 50 is attached to the upper surface of a dashboard 60 of a passenger car, which is an installation surface, via the monitor stand 1.

  As shown in FIG. 5, the turning block 4 is set and fixed at a desired turning position, and the screen of the monitor 50 is matched with the driver's eyes on the driver's seat 61 side. Further, as shown in FIG. 5A, when the monitor 50 is high and a dark field portion A indicated by hatching in the figure is generated on the dashboard 60 by the monitor 50, the fixing handle and the fixing means are again provided. After loosening and adjusting the inclination angles of the support arm 5 and the monitor mounting block 6 as appropriate, the fixing handle and the fixing means are tightened, and as shown in FIG. Is fixed below the upper surface of the dashboard 60. As a result, the monitor 50 can be fixed at a position where the monitor 50 can be seen most easily without obstructing the driver's field of view. Then, once tightened and fixed, each joint portion is firmly held at the angular position by the meshing of the spline grooves, so that position fluctuation due to vibration during traveling is also prevented.

  In the embodiment, the case where the monitor stand of the present invention is applied to a monitor of a car navigation system is shown, but it is needless to say that the monitor stand can be applied to a monitor of an in-vehicle television.
