Description

  The present invention relates to a display device including an inclination adjustment mechanism.

  A display device represented by a display of a television or a computer is generally a heavy CRT having its own weight, but in recent years, a thin and light display device called a flat panel display is becoming widespread. A liquid crystal display is a typical example, but there are also a plasma display and an EL display.

These display devices have a wide range of screen sizes ranging from 1.5 to 5 inches for portable or in-vehicle use to several hundred inches for outdoor display. There are a wide variety of uses and installation locations. For example, an in-vehicle display device is not necessarily horizontal, such as an upper surface of a dashboard, so that the mounting portion of the display unit is a horizontal plane in addition to a tilt mechanism and a horizontal swing mechanism for adjusting the elevation angle. There is known one that can adjust the inclination of the display screen with respect to (see, for example, Patent Document 1).
Some word processors and the like are also provided with a mechanism that rotates the screen 90 degrees mainly in accordance with vertical writing and horizontal writing applications so that the screen is vertically or horizontally (see, for example, Patent Document 2).

On the other hand, in order to save the installation area and pursue the beauty of design by taking advantage of the thin and lightweight features of flat panel display, a vertical support is set up integrally with the base and displayed at the tip There is a display device with a structure for attaching the part. In such a display device, since the base part of the base end part and the display part of the front end part are attached via a thin column, the display part tends to be inclined with respect to the horizontal due to a slight dimensional error in attachment. . Even if the tilt angle is slight, if the sides of the display rectangle are tilted with respect to the installed platform, surrounding shelves, walls, windows, etc., the tilt is visually recognized and used. It can be uncomfortable for the person and cause the product quality to deteriorate. Moreover, even if there is no problem in the assembly of the display device itself, the same discomfort occurs when the stand or floor on which the device is installed is slightly bent. Such a tilt requires a small amount of adjustment, and once adjusted after installation, it does not require many adjustments thereafter. Therefore, even if a complicated tilt adjustment mechanism provided in the above-mentioned in-vehicle display device or word processor is provided for such tilt adjustment, it is doubtful whether an advantage sufficient to meet the cost increase due to the increase in the number of parts can be obtained. I'm sorry. A means for providing an inexpensive tilt adjustment mechanism with a simple structure without increasing the number of parts is desired. The present invention has been made in consideration of such circumstances.
Japanese Patent Laid-Open No. 9-249077 Japanese Patent Laid-Open No. 11-249577

  The problem to be solved by the present invention is to provide a display device having a function capable of adjusting the tilt of the display unit according to the situation where the display device is installed by a simple mechanism.

  The present invention includes a support column having a distal end portion, a proximal end portion, and an intermediate portion therebetween, a display unit supported by the distal end portion of the support column, a proximal end support portion that supports the proximal end portion of the support column, A member that rotatably supports the intermediate portion, the center of which is eccentric with respect to the axis of the support column, and an inclination adjusting member having a contact portion that contacts the circumference through which the support column passes, and at least a part of the circumference The present invention provides a display device comprising: an eccentric support portion that is configured to be rotatably contacted by a circumferential contact portion.

  The base end portion of the column is freely supported by the base end support portion, and the angle formed between the bottom of the display portion and the horizontal plane is adjusted according to the rotation of the tilt adjustment member with the supported point as a fulcrum. It is desirable to configure.

  The display device according to the present invention includes an inscribed or circumscribed portion for rotating a member along a circumference, and a column support portion that is provided eccentrically with respect to the circumference and rotatably supports an intermediate portion of the column. Since the tilt adjusting member having the above-mentioned structure is rotated and the tilting direction of the column, that is, the tilt of the display unit can be adjusted by rotating the member, the tilt of the display unit can be adjusted by a simple mechanism with a small number of parts.

  Preferably, the base end portion of the column is freely supported by the base end support portion, and the angle formed between the bottom of the display portion and the horizontal plane is adjusted according to the rotation of the tilt adjustment member with the supported point as a fulcrum. If comprised so, the inclination of the display part connected to a support | pillar can be adjusted with a simple mechanism with few number of parts.

  The display device of the present invention includes an adjustment mechanism that adjusts the inclination of the display unit. Here, the tilt adjustment of the display unit refers to adjusting the angle formed between the bottom of the rectangular display unit and the horizontal plane in a state where the display device is installed. The tilt adjustment is performed according to the user's request so that the installed display device does not feel uncomfortable with the surroundings, and usually the adjustment angle is very small. The sense of discomfort with the surroundings occurs, for example, when the stand bottom and the bottom of the display unit are not kept parallel due to an assembly error of the display device. Or, even if there is no assembly error in the display unit itself, if the base or floor on which the device is installed is slightly bent or tilted, the bottom of the display unit has an angle with the horizontal, which is visually uncomfortable. May give.

  Also, being freely supported is a state in which the supported object can change its direction three-dimensionally within a certain range around the supported point, and its movement is restricted within a specific plane. A state that is never done. However, it is not always necessary to be able to rotate 360 degrees around the fulcrum, and may be within a certain range.

  The display unit included in the display device of the present invention is a so-called flat display, and is preferably a display device such as a liquid crystal display, a plasma display, or an EL, but is not limited thereto. For example, a display using an LED or the like may be used, as long as it has a structure that can be attached to the tip of a column that stands on a stand.

  The display content is not limited, and may be, for example, a computer image display, a TV broadcast, a video display such as a DVD, a car navigation, or an advertisement message. .

An inner diameter of the column support portion of the inclination adjusting member may be set to be larger than an outer diameter of the column and smaller than a diameter of a circumference contacting the inscribed portion or the circumscribed portion.
Further, the tilt adjusting member only needs to be rotatable at least 180 degrees along the circumference of the intermediate support portion.
By doing this, the eccentric direction of the shaft of the support column changes by 180 degrees within the rotation range of the tilt adjustment member. Therefore, the rotation range includes a point where the tilt to the left and right of the support column becomes maximum when viewed from the front. An adjustment range is obtained.

The base end support portion may be provided at the bottom of the elevating member, the intermediate support portion may be provided above the lower portion of the elevating member, and the support column may be configured to be able to move up and down.
In this way, the display unit connected to the support can be raised and lowered, so that not only the inclination of the display unit but also the height can be adjusted. In addition, since the base end support portion and the intermediate support portion are provided on the elevating member, the inclination of the display portion is kept constant regardless of the elevation.

A stationary member that acts on the elevating member and stops elevating the elevating member may be further provided, and the stationary member may be disposed on a substantially front surface or a substantially back surface of the elevating member. The stationary member can be configured using, for example, a spiral spring or a coil spring.
If it carries out like this, a display part can be raised / lowered by slight force by the effect | action of a stationary member.

Further, the present invention provides a support member having a base having a support, a tip end portion, a base end portion, and an inclination adjustment fulcrum that is freely supported by the tip end portion of the support post, and is supported by the tip end portion of the support member. A tilt adjustment member having a display unit, a support column rotatably supported, a tilt adjustment member that is eccentric with a shaft of the support column and is in contact with a circumference through which the support column passes, and at least a part of the circumference Provided is a display device characterized in that an eccentric support portion, which is configured to be pivotally in contact with a circumferential contact portion, is disposed at a base end portion of a support member.
Even in this case, the inclination of the display unit can be adjusted by a simple mechanism having a small number of parts.
Here, for example, in a display device installed on a desk, the base refers to a stand member that comes into contact with the desk or an adapter member that is mounted on a dashboard in order to mount the display device.

Hereinafter, examples of the display device of the present invention will be described in detail based on the embodiments shown in the drawings.
(Embodiment 1)
FIG. 1 is an explanatory diagram for explaining a mechanism for tilt adjustment in an embodiment of a display device including the tilt adjustment mechanism of the present invention. FIG. 2 is an explanatory view showing each part constituting the apparatus.

  As shown in FIG. 2, the display device 20 is attached to the upper end portion of the support column 3 on which the display unit 1 supports the display device 20 via the attachment member 2. The display unit 1 and the column 3 move together in the tilt adjustment direction of the display device of the present invention, that is, the rotation direction about the line of sight of the user looking at the display surface. However, the elevation angle, that is, the angle formed by the line of sight and the horizontal plane may be adjusted by providing a tilt mechanism on the mounting member 2 and adjusting the angle. If the tilt mechanism is provided, the user can adjust the angle of the display unit so that the display surface is substantially perpendicular to the line of sight according to the height of his / her eyes when used. In consideration of convenience during use, many display devices provided with such an adjustment mechanism are known.

  The support column 3 is fitted with an opening 18 provided at the upper end of the inclination adjusting member 4, and the intermediate portion of the support column 3 is supported by the fitting with the opening 18. The tilt adjusting member 4 will be described in more detail later.

A ball end 6 is fixed to the lower end portion of the column with screws 5. The diameter of the ball end 6 is larger than the diameter of the column 3 and is slightly smaller than the inner diameter of the stand 7 that accommodates them. In the state accommodated in the stand 7, the center of the ball end 6 is positioned almost uniformly in a plane perpendicular to the support column, and the size of the inner diameter of the stand 7 is selected so as to move freely within the stand 7. The above fitting size may be set so that a frictional force that turns only when an external force of a certain level or more is applied to the ball end. The ball end 6 is attached to the support column 3, and the display unit 1 is attached to the support column 3. However, if the fitting size is appropriately selected, an appropriate frictional force is generated as described above, and the display unit 1 has a slight amount. When force is applied, the display unit 1 is rotated about the support column 3 as a result, and a problem that the position is not fixed can be prevented. In one embodiment, the diameter of the ball end 6 is 24 mm + 0 / −0.1 mm, and the inner diameter of the stand 7 is 24 mm + 0.1 mm / −0.
The support column 3 is inserted into the receiving portion of the stand 7, and the ball end 6 attached to the lower end of the support column 3 comes into contact with the bottom plate 8 of the stand 7 to determine the vertical position of the support column 3.

  The tilt adjusting member 4 is placed on the upper end portion of the stand 7. In this state, the tilt adjusting member 4 selects the dimensions of the inner diameter of the tilt adjusting member 4 and the outer diameter of the upper end of the stand 7 so that the tilt adjusting member 4 can rotate while contacting the outer periphery of the upper end of the stand 7. In one embodiment, the inclination adjusting member 4 has an inner diameter of 20.1 mm + 0.3 mm / −0, and an outer diameter of the upper end of the stand 7 is 20 mm + 0 / −0.1 mm.

  The tilt adjusting member 4 may be provided with a mechanism for preventing the stand 7 from coming off. As shown in FIG. 2, this mechanism cuts a groove around the vicinity of the upper end of the stand, provides a pin hole in the side wall portion of the tilt adjusting member 4 so as to correspond to the groove, and inserts a pin screw to This can be realized by fixing an appropriate depth that can be prevented but does not prevent the rotation (see, for example, reference numeral 19b in FIG. 5 and reference numerals 19a and 19c in FIG. 8).

  As shown in FIGS. 4 and 5, the inclination adjusting member 4 does not need to be in a cylindrical shape that is in contact with the entire periphery of the upper end of the stand 7, but may be in a shape that is in partial contact. The opening 18 fitted to the support 3 does not need to be in contact with the support 3 over the entire circumference, and may have a shape that is in partial contact.

  FIG. 3 is a cross-sectional view showing a portion related to tilt adjustment of the display device of FIG. As shown in the figure, the column 3 and the ball end 6 are accommodated in the accommodating portion of the stand 7, and the inclination adjusting member 4 is placed on the upper end portion of the stand 7.

  FIG. 4 is a plan view showing the shape of the opening 18 of the tilt adjusting member 4 which is a feature of the present invention. 4A, 4 </ b> B, and 4 </ b> C show states in which the same inclination adjusting member 4 is at +90 degrees, 0 degrees, and −90 degrees with respect to a certain reference position, respectively. As shown in the figure, an opening 18 is provided at the upper end of the inclination adjusting member 4 with the dimension being eccentric by d with respect to the outer periphery thereof. FIG. 5 is a cross-sectional view corresponding to A-A ', B-B' in (b), and C-C 'in (c) shown in FIG. The upper end portion of the stand 7 that is in contact with the outer periphery of the inclination adjusting member 4 and the support column 3 that fits into the opening 18 are arranged eccentric to each other. And the eccentric direction of the support | pillar 3 with respect to the stand 7 changes by rotating the inclination adjustment member 4. FIG. On the other hand, a ball end 6 is attached to the lower end of the column 3, and the ball end 6 is positioned so that its center substantially coincides with the center of the inner diameter of the stand 7. That is, the lower end portion of the column 3 to which the ball end 6 is attached and the stand 7 that accommodates the ball end 6 are disposed substantially concentrically with each other. In addition, the ball end 6 is supported freely with respect to the stand 7. Therefore, the support column 3 is arranged in a state where the lower end is concentric with the stand 7 and the middle part is eccentric with the stand 7. And the direction of the inclination of the column 3 is changed by rotating the inclination adjusting member 4. In accordance with the change in the tilt direction, the tilt of the display unit 1 also changes. This is the tilt adjustment mechanism included in the display device of the first embodiment.

  FIG. 1 is an explanatory diagram showing the tilt adjustment. 1A, 1B, and 1C correspond to the positions of the inclination adjusting member 4 in FIGS. 4A, 4B, and 4C, respectively. FIG. 1A shows a state in which the opening 18 of the tilt adjusting member 4 is eccentric to the left with respect to the outer periphery thereof. In this case, since the upper end of the column 3 is tilted to the left of the lower end and the display unit 1 is also tilted to the left, the heights L and R of the left and right ends of the bottom of the display unit 1 have a relationship of L <R. FIG. 1B shows a state in which the opening 18 of the inclination adjusting member 4 is eccentric to the front side with respect to the outer periphery thereof. In this case, the upper end of the support column 3 is tilted to the near side of the lower end, but there is no left-right tilt. Accordingly, the display unit 1 is slightly tilted toward the front side, but has no left / right tilt, and is in a state of L = R. Since the inclination toward the front or back is slight, there is no visual discomfort or inconvenience for the user due to the forward inclination. Further, if the mounting member 2 is provided with a tilt mechanism, it can be adjusted by the mechanism. FIG. 1C shows a state in which the opening 18 of the inclination adjusting member 4 is eccentric to the right side with respect to the outer periphery. In this case, the upper end of the support column 3 is tilted to the right side of the lower end, and the display unit 1 is also tilted to the right side so that L> R. In the description, three angles of -90 degrees, 0 degrees, and 90 degrees have been described, but the effect of tilt adjustment obtained at angles other than these is apparent from the above description. By tilting the tilt adjusting member 4, the tilt can be finely adjusted. The tilt adjusting member 4 can be adjusted by making the maximum use of the tilt adjustment width of this mechanism as long as it can rotate at least 180 degrees.

  In order to prevent the display unit 1 from rotating around the column 3 when the tilt is adjusted, for example, a vertical groove is provided on the inner wall of the stand 7 so that the ball end 6 fits into the groove. You may make it have a part shape. In this way, it is possible to prevent the ball end 6 from rotating around the support column 3, and therefore the display unit 1 also does not rotate.

Further, the stand 7 to which the inclination adjusting member 4 is attached only needs to have a cylindrical shape at the upper end, and the shape of the portion other than the upper end is not particularly limited as long as the column 5 can be accommodated. FIG. 6 is a perspective view showing a different embodiment of the display device of the present invention. As shown in the figure, the portion other than the upper end may be formed in, for example, a prism.
Furthermore, the shape of the stand 7 is not limited as long as it supports the lower end portion and the middle portion of the support column 3, and does not necessarily need a cylindrical shape that accommodates the support column inside.

(Embodiment 2)
FIG. 7 is an explanatory diagram showing the configuration of the second embodiment of the display device of the present invention.
The display device 21 shown in FIG. 7 has a mechanism in which the display unit 1 moves up and down together with the support column 3 to which the display unit 1 is attached, and the height of the display unit 1 can be adjusted.

  The column 3 is fitted to the eccentric opening 18 of the tilt adjusting member 4 at the intermediate portion thereof, and the ball end 6 is attached to the lower end with a screw 5 in the same manner as the display device 20 shown in FIG. The difference from the former is that the column 3 is not directly supported by the stand 7 but is accommodated in the elevating member 9, and the elevating member supports the lower end and the middle part of the column 3. The diameter of the ball end is slightly smaller than the inner diameter of the elevating member 9 that accommodates it. The support column 3 with the ball end 6 attached to the lower end abuts the bottom of the elevating member 9 to determine the vertical position. The inclination adjusting member 4 is put on the upper end portion of the elevating member 9 so as to be rotatable. Accordingly, the support column 3 is arranged with its lower end concentric with the elevating member 9 and with its middle part eccentric with the elevating member 9. The direction of inclination changes by rotating the inclination adjustment member 4. Thereby, the inclination of the display unit 1 can be adjusted.

  The elevating member 9 is housed inside the stand 7. On the back side of the stand 7, a notch 10 is provided in the ascending / descending direction. The lifting spring 11 is attached to the back surface of the stand 7 together with the spring holding member 12. At this time, the spring portion at the upper end of the elevating spring 11 protrudes from the notch portion 10 into the stand 7. The elevating member 9 is inserted into the stand 7 from above, and the bottom portion of the elevating member 9 contacts the spring portion of the elevating spring 11. Since the elevating member 9 accommodates the support column 3 having the display unit 1 attached to the upper end portion thereof, its own weight is applied to the elevating spring 11, and the spring is extended.

When the elevating spring 11 is extended, a repulsive force is generated due to deformation, but the elevating spring 11 is designed to obtain a substantially constant repulsive force within the range of the top dead center and the bottom dead center of the elevating mechanism. Yes. As a result, the bottom of the elevating member 9 and the elevating spring 11 come into contact with each other to balance the weight of the elevating member 9 and the repulsive force of the spring. The elevating member 9 is housed inside the stand 7. However, if the fitting dimension between the outer shape of the elevating member 9 and the inner diameter of the stand 7 is appropriately selected, an appropriate frictional force can be generated. In this way, when a slight force is applied to the display unit 1, it is possible to prevent the display unit 1 from rotating about the elevating member 9 and causing the position to be unstable. In one embodiment, the elevating member 9 has an outer diameter of 30 mm + 0 / −0.1 mm, and the stand 7 has an inner diameter of 30 mm + 0.1 mm / −0.
Further, in order to prevent the display unit 1 from rotating about the elevating member 9, a groove is provided on the inner wall of the stand 7 along the elevating direction, and the outer wall of the elevating member 9 has a convex portion that fits into the groove. It may be. If it does in this way, it can prevent that the display part 1 rotates centering | focusing on the raising / lowering member 9 irrespective of a frictional force.

  FIG. 8 is a cross-sectional view showing a part related to the elevation and tilt adjustment of the display device of FIG. As shown in the figure, the support column 3 and the ball end 6 are accommodated in the elevating member 9, and the inclination adjusting member 4 is placed on the upper end portion of the elevating member 9. And the raising / lowering member 9 is accommodated in the stand 7 so that raising / lowering is possible, and the bottom part contact | abuts to the spring 11 for raising / lowering. The weight of the lifting part including the display unit 1 and the repulsive force of the lifting spring 11 are balanced to fix the display unit to a desired height.

According to this configuration, since the lift mechanism and the tilt adjustment mechanism of the display unit are completely independent, once the tilt of the display unit is adjusted, the tilt of the display unit is adjusted even if the height of the display unit is adjusted thereafter. Will not change.
(Embodiment 3)
FIG. 9 is an explanatory view showing a third embodiment of the tilt adjusting mechanism of the present invention. In the display device 22 shown in the figure, the tilt adjustment member 4 is disposed below the tilt adjustment fulcrum.

  The display unit 1 is attached to an upper end portion of a cylindrical support member 15 that supports the display unit 1 via an attachment member 14. On the other hand, the stand 17 has a column 16, the lower end of the column is integrated with the base portion of the stand, and the ball end 6 is attached to the upper end. The support column 16 is fitted to the eccentric opening 18 of the inclination adjusting member 4 at the intermediate portion thereof, and the ball end 6 is attached to the upper end. The support member 15 accommodates the support column 16 and the ball end 6 therein. The diameter of the ball end 6 is larger than the diameter of the support column 16 and slightly smaller than the inner diameter of the support member 15 that accommodates them. The size of the inner diameter of the stand 7 is selected so that the center of the ball end 6 is positioned almost uniformly in a plane perpendicular to the support column and can be freely moved in the guide 6 while being accommodated in the support member 15. That's fine.

The support 16 is inserted into the support member 15, and the ball end 6 attached to the upper end is brought into contact with the upper end of the support member 15 to determine the vertical position.
The tilt adjusting member 4 is placed on the lower end portion of the support member 15. In this state, the tilt adjustment member 4 may be selected with the dimensions of the inner diameter of the tilt adjustment member 4 and the outer diameter of the lower end portion of the support member 15 so that the tilt adjustment member 4 can rotate while contacting the outer periphery of the lower end portion of the support member 15. . Therefore, the support column 16 is arranged with its upper end concentric with the guide 16 and its intermediate portion eccentric with the guide 16. The direction of inclination changes by rotating the inclination adjustment member 4. Thereby, the inclination of the display unit 1 can be adjusted.

  The support member 15 to which the inclination adjusting member 4 is attached only needs to be cylindrical at the lower end, and the shape of the portion other than the lower end is not particularly limited as long as the column 16 can be accommodated. Furthermore, the shape of the support member 15 may be any shape as long as it is supported by the upper end portion of the support column 16 and to which the tilt adjusting member 4 is attached below, and does not necessarily have a cylindrical shape that accommodates the support column inside.
