Display panel support device

Technical field

The present invention relates to a display panel support device that supports a display panel made of a liquid crystal panel or the like so that the height and support angle (tilt angle) can be adjusted and can be folded.

Background art

Conventionally, display panels such as liquid crystal panels and plasma display panels have been proposed to be supported by a support device capable of adjusting the height and support angle (tilt angle). The display panel is supported on the base via an arm, and the display panel and the arm are connected by a rotating shaft with a brake (a shaft that can be rotated only after a certain amount of force is applied). The arm is connected by a rotating shaft with a brake.

A structure composed of the arm force S-link mechanism has been proposed (for example, see Patent Document 1). According to this support device, the arm can be rotated by the rotation axis with the base, and the height can be adjusted. At this time, since the arm is configured by the link mechanism, the inclination angle of the display panel can be adjusted. The height can be adjusted without changing, and the display panel can be rotated around the axis of rotation with the arm, and the tilt angle can be adjusted.

[0003] In addition, the display panel is supported with respect to the base via an arm, and the display panel and the arm and the arm and the base are connected to be swingable at a hinge portion, and a torsion spring is interposed in the hinge portion. A mounted support device (see, for example, Patent Document 2) has been proposed. According to this support device, the height can be adjusted by swinging the arm at the hinge portion with the base, and the tilt angle can be adjusted by swinging the display panel at the hinge portion with the arm. .

[0004] Furthermore, the display panel is supported with respect to the base via an arm, and the display panel, the arm, and the arm and the base are connected to each other so as to be pivotable. An intermediate portion of the arm is one end of the link. A support device is proposed in which the other end of the link is connected to a movable member that can move back and forth, and a screw rod is screwed onto the movable member (see, for example, Patent Document 3). Has been. According to this support device, when the screw rod is rotated forward and backward, the moving member is moved. It can be moved back and forth, and the arm can be raised and lowered via the link to adjust the height.

Disclosure of the invention

Problems to be solved by the invention

[0005] As shown in Patent Document 1, the display panel is connected to the arm, the base, the arm, the force S, and a rotating shaft with a brake (a shaft that can be rotated only when a certain force is applied). For the display panel, the height and inclination angle of the display panel is maintained by the rotating shaft with brake, and the height is adjusted by raising and lowering the arm by applying a force greater than the braking force of the rotating shaft with brake. In addition, the tilt angle can be adjusted by moving the display panel. Therefore, the braking force of the rotating shaft with brake must be high enough to support the weight of the display panel and maintain its posture, so height adjustment and inclination angle adjustment are considerable. There is a problem that power is required and operability is bad. Also, if the display panel is made larger and the weight is heavier, a greater braking force is required, so that the operability is further deteriorated and the display panel that can be supported is limited. Moreover, in the support apparatus of the cited reference 1, no consideration is given to reducing the thickness when folded.

[0006] In addition, a display panel, an arm, a base, an arm, and a hinge portion that interposes a force torsion spring as shown in Patent Document 2 are torsion springs for the weight of the display panel. To counteract, it is necessary to use a relatively large torsion spring, and because of the spring characteristics, the lifting force tends to be too large at the lower position of the arm, and the lifting force tends to be insufficient at the higher position of the arm. The operability changes depending on the undulation angle and the tilt angle of the display panel, and there is a problem that is unsuitable for a large and heavy display panel support device. In short, when a torsion spring or the like is used by directly twisting it within the arm operating angle range, linear characteristics are proportional to the angle unless the operating point changes, and the balance characteristics of the balance are not good. The reliance on the mechanism (sliding friction) is large and the operability is poor. Furthermore, since the support device as in Patent Document 3 requires the operation of the screw rod for adjusting the height, there is a disadvantage that the operation becomes troublesome.

[0007] In addition, conventional support devices generally have poor balance characteristics in the operating range against the weight of the display panel, and therefore rely heavily on a friction (sliding friction) mechanism or the like. Conventional support devices are insufficiently slim and small in size, have a thickness when folded, and have a problem in terms of economy because they have a large space for storage and transportation.

[0008] The present invention has been proposed to solve such a problem, and its purpose is to achieve a perfect balance characteristic in which the spring characteristic counters the fluctuation moment during the elevation (height adjustment) relative to the weight of the display panel. It can be moved with very light force (height adjustment) and has good operability! In the ascending / descending range (height adjustment range)! The aim is to provide a display panel support device that is slimmed down (thinned) so that the thickness of the arm is as much as the space of the spring, and is thin when folded.

Means for solving the problem

[0009] In order to solve the above-mentioned problems, in the display panel support device of the present invention, a display panel mounting frame is pivotally attached to the tip of an arm pivotally attached to a base, A display panel support device for attaching a display panel to a frame,

The arm is composed of a link mechanism, and the display panel mounting frame is pivotally attached to the link shaft of the link mechanism via a friction mechanism.

The link mechanism is provided with a spring that opposes a rotational moment mainly due to the weight of the display panel mounted on the display panel mounting frame.

If the spring is a tension spring or a compression spring, it is possible to counter the rotational moment mainly due to the weight of the display panel with a simple configuration.

In this invention, “mainly against the rotational moment due to the weight of the display panel” means that the arm (link mechanism) faces downward toward the base mainly due to the weight of the display panel (the display panel attached to the mounting frame). It is meant to counteract by urging in the opposite direction (in the direction to raise the position of the display panel) against the rotational moment to be rotated in the direction of lowering the height position. In addition, “mainly” to counter the rotational moment due to the weight of the display panel In addition to the rotational moment due to the weight of the display panel, the arm is also subject to other moments such as other mounting frames. "".

Thus, the height of the display panel mounted on the display panel mounting frame can be adjusted by rotating (up-and-down movement) the arm formed by the link mechanism with respect to the base. At this time, since the link mechanism is provided with a spring that counters the rotational moment due to the weight of the display panel, if the external force whose height is adjusted is removed, the rotational moment mainly due to the weight of the display panel and the rotational moment The spring force of the spring against the balance is balanced, the balance stops and free-stops, and adjustment is possible with a light force, resulting in good operability. Further, since the arm is constituted by a link mechanism, the tilt angle of the display panel does not change even if the height of the display panel is adjusted. The display panel can be adjusted with respect to the tilt angle by pivoting about a link shaft with a friction (friction resistance) mechanism interposed therebetween. The adjusted inclination angle is maintained by a friction (friction resistance) mechanism.

In addition, the arm (link mechanism) is rotated at the base mounting portion of the base, and the display panel mounting frame is rotated at the shaft mounting portion with the arm (link shaft of the link mechanism) and folded on the base. Became possible

[0011] When the link mechanism is a four-bar link, the configuration is easy and a reliable operation can be achieved.

Further, if the link member forming the link mechanism is composed of two parallel plate-like bodies, the thickness of the arm can be reduced. In addition, if a spring that mainly counteracts the rotational moment due to the weight of the display panel is built in between these parallel plates, it is possible to provide a spring S that does not increase the thickness of the arm. Therefore, the thickness of the arm can be reduced. Further, since the spring is built in between the plate-like bodies, it is prevented from being interfered with by other members, and a reliable operation is ensured.

[0012] Further, in the display panel support device of the present invention, the portion of the link member forming the link mechanism on which the display panel mounting frame is pivotally attached is bent to form a rising portion, which is used for mounting the display panel. The frame is pivotally attached to the rising portion. Thus, when the display panel support device is folded, the display panel is within the height of the rising portion. Since a part of the screen support device, for example, the display panel mounting frame portion can be accommodated, the thickness when the display panel support device is folded can be reduced.

[0013] Further, the display panel mounting frame of the display panel support device of the present invention is provided with a restricting means for restricting the rotation to a certain range and a releasing means for releasing the restriction of the restricting means! /, Characterized by.

In this way, the adjustment range of the tilt angle of the display panel mounted on the display panel mounting frame is restricted to a certain range by the restricting means during use, and when not in use or transported, it is released by the releasing means and the rotation range is expanded to fold the display panel. Can be possible.

(3) The link mechanism that constitutes the arm is equipped with a spring that counteracts the rotational moment due to the weight of the display panel, and the rotational moment due to the weight of the display panel mainly balances the spring force of the spring against this rotational moment. Because of this configuration, even if the height is adjusted, the balance can always be kept still and free-stopped.

(4) Since the arm is composed of a link mechanism! /, The tilt angle of the display panel does not change even if the height of the display panel is adjusted! /.

[5] (5) Since the frame to which the display panel is attached is pivotally attached to the link shaft of the link mechanism via a friction mechanism, the display panel is rotated around the link shaft and tilted. The corner can be adjusted. The adjusted tilt angle is maintained by the friction mechanism.

(6) The arm (link mechanism) is pivoted at the pivot point with the base, and the frame with the display panel is pivoted at the pivot point with the arm (link shaft of the link mechanism). Regulation by means of regulation Is released by the release means. ) And can be folded on the base.

(7) The link member forming the link mechanism is a parallel plate-like body, and a spring that mainly counters the rotating moment due to the weight of the display panel is built in between the parallel plate-like bodies. The thickness of the spring can be reduced, and the spring is protected from interference with other members, ensuring reliable operation.

[0016] (8) The portion of the link member forming the link mechanism on which the display panel mounting frame is pivotally mounted is bent to form a rising portion, so that the arm and the display panel mounting frame are folded. At this time, the display panel mounting frame part can be accommodated within the height of the rising part, so that the display panel support device can be folded together with the thinning of the arm. it can.

(9) Accordingly, the exclusive storage space for each vehicle can be small, and the same storage space can increase the storage capacity, thereby improving the cost of transportation and the like.

(10) The display panel attached to the display panel mounting frame can be regulated by the regulating means for the adjustment range of the tilt angle, and can be folded by releasing the regulation by the regulating means and expanding the rotation range. it can.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a display panel support device showing an embodiment of the present invention, FIG. 2 is a side view for explaining an operating state of height adjustment of the display panel showing an embodiment of the present invention, and FIG. FIG. 4 is a side view for explaining an operation state of tilt angle adjustment of the display panel of the display panel support device showing the embodiment of the present invention, and FIG. 4 is a view showing a state in which the display panel support device showing the embodiment of the present invention is folded. It is a side view.

In the same figure, the display panel support device includes a base 2, an arm 3 pivotally attached to the base 2, and a display panel pivotally attached to the tip of the arm 3. The display panel 1 is mounted on the display panel mounting frame 4 and pivots (moves up and down) around the axis 2 of the base 2 as shown in FIG. By adjusting the height of the display panel 1 as shown in FIG. 3, the display panel mounting frame 4 is pivoted (back and forth) about the axis 3 with the arm 3 as shown in FIG. Tilt angle It can be adjusted. In this configuration, the display panel mounting frame 4 can be folded as shown in FIG. 4 by rotating the display panel mounting frame 4 in the arrow X direction and the arm 3 in the arrow Y direction in FIG.

The arm 3 is composed of a link mechanism 5, and the display panel mounting frame 4 is pivotally attached to the link shaft 6 of the link mechanism 5 with a friction mechanism 15 (details will be described later) interposed therebetween. . Therefore, even if the height of the arm 3 is adjusted by rotating (up and down) the arm 3 around the pivot point with the base 2, the arm 3 is composed of the link mechanism 5. The inclination angle does not change. The tilt angle of the display panel 1 can be executed by rotating (back and forth) about the link shaft 6. The attitude of the tilt angle of the display panel 1 is held by the friction mechanism 15.

In addition, when adjusting the height by rotating (moving up and down) the arm 3, the link mechanism 5 constituting the arm 3 is balanced against the rotational moment due to the weight of the display panel 1. 7 is adopted, and a configuration that always allows balance stationary, that is, free stop is adopted.

[0019] This will be described in more detail. FIG. 5 is a perspective view in which the case of the display panel support device showing the embodiment of the present invention is removed to expose the internal structure, FIG. 6 is an exploded perspective view thereof, and FIG. 7 is a central longitudinal sectional view of FIG.

The link mechanism 5 constituting the arm 3 includes a first link member 8 and a second link member 9 in which the link member is formed of a plate-like body, and the first link member 8 and the second link member 9 are They are provided in parallel. Specifically, the plate-like bodies of the first and second link members 8 and 9 are rectangular, and both longitudinal sides thereof are bent to form side walls 8a, 8b, 9a and 9b, and the width of the second link member 9 is the first. It is formed smaller than the width of one link member 8, and the first and second link members 8, 9 are overlapped in parallel so that both side walls 8a, 8b, 9a, 9b face each other. Then, since the second link member 9 is smaller in width force S and smaller than the first link member 8, the second link member 9 is inserted into the side walls 8a and 8b of the first link member 8 and overlapped therewith. Between the two link members 9, spaces corresponding to the heights of the side walls 8a, 8b, 9a, and 9b are formed. A tension spring 7 is built in this space. Thereby, the thickness of the arm 3 can be reduced, and interference from other members of the tension spring 7 can be prevented. [0021] The lower ends of the first link member 8 and the second link member 9 formed in this way are attached to the base 2 by shafts 11 and 12 threaded between the side walls 8a and 8b and between the side walls 9a and 9b. Attached to the provided bracket 10 so as to be rotatable. In this example, the shafts 11 and 12 are attached to the bracket 10 with a common bearing member 13 to eliminate the “backlash” between the shafts, to prevent the occurrence of sliding noise, and to enable smooth movement and ease of operation. Durability is improved. Further, the mounting positions of the shafts 11 and 12 to the bracket 10 are such that the first link member 8 is located above and the second link member 9 is located obliquely below.

[0022] The upper ends of the side walls 8a, 8b of the first link member 8 are formed at the bent rising portions 14, and the mounting frame 4 of the display panel 1 is connected to the link shaft 6 at the rising portions 14 of the side walls 8a, 8b. , 6 can be pivotally attached. A display panel mounting frame 4 is attached to the link shafts 6 and 6 via a friction (also referred to as frictional resistance or sliding resistance) mechanism 15 as shown in FIGS.

Note that a friction mechanism may be interposed in one or both of the attachment portion of the first link member 8 to the shaft 11 and the attachment portion of the second link member 9 to the shaft 12.

FIG. 8 is a perspective view of a portion where the display panel mounting frame 4 is attached to the link shafts 6 and 6 with the friction mechanism 15 interposed therebetween, FIG. 9 is a cross-sectional view of the link shaft 6 portion, and FIG. FIG. 6 is an exploded perspective view of six parts of a shaft.

In the friction mechanism 15, the link shaft 6 has a non-circular cross-sectional shape, for example, a D-cut or WD-cut shape, and the first link member 8 and the display panel mounting frame 4 are rotatably mounted on the link shaft 6 through a circular hole. As shown in FIG. 9, friction plates with non-circular holes corresponding to the non-circular shape of the link shaft 6 are formed on both sides of the rising portion 14 of the first link member 8 and on both sides of the display panel mounting frame 4. (Friction washer) 16 is configured to be pressed and abutted so as to be non-rotatable and axially movable. Therefore, the display panel mounting frame 4 cannot be rotated unless a force of a certain level or more is applied due to the frictional resistance (sliding resistance) between the display panel and the position of the display panel mounting frame 4. The strength of the frictional resistance at this time can be adjusted by adjusting the tightening force with the nut 17. As a result, the display panel 1 mounted on the display panel mounting frame 4 can be adjusted in inclination angle by applying a certain force, and when the force is removed, the display panel 1 maintains its posture. In this example, both ribs provided on both side walls 8a and 8b are used. Since the friction mechanisms 15 are provided on the link shafts 6 and 6, a reliable free stop is possible, and both friction mechanisms 15 and 15 counteract the weight of the display panel 1, so the friction of each friction mechanism 15 Since the resistance can be set weakly, it can be moved with a light force and the operability can be improved.

In addition, a substantially circular stopper plate 18 is provided on the link shaft 6 so as not to rotate, and a notch 18 a is provided on the outer peripheral surface of the stopper plate 18.

On the other hand, the display panel mounting frame 4 is provided with a locking plate 19 that is slidable toward the outer peripheral surface of the stopper plate 18, and this locking plate 19 is pressed by a spring 20 to slide. It is in contact with the outer peripheral surface of the topper plate 18.

Therefore, when the locking plate 19 is located in the notch 18a of the stopper plate 18, it can only be rotated within the range of the notch 18a, and the inclination angle can be adjusted within this range. Then, by sliding the locking plate 19 and removing it from the notch 18a of the staggered plate 18, the rotation of the display panel mounting frame 4 is released as the restriction is released. This is the restricting means for restricting the rotation of the display panel mounting frame ₄ to a certain range and the releasing means for releasing the restriction of the restricting means.

The bearing member 21 has the same function as the stopper plate 18 by providing a configuration similar to the stopper plate 18 such as providing a notch on the outer peripheral surface of the attachment portion of the bearing member 21 to the link shaft 6. S can. Naturally, the locking plate 19 in this case is advanced and retracted toward the outer peripheral surface of the attachment portion of the bearing member 21 to the link shaft 6. In this case, the stagger plate 18 is not necessary, and the number of parts can be reduced accordingly.

[0025] In addition, a first non-circular hole corresponding to the non-circular shape of the link shaft 6 is attached to both of the link shafts 6 and 6 provided on the side walls 8a and 8b of the first link member 8. 2 The bearing members 21 and 21 that connect the upper ends of the link members 9 are non-rotatably attached. The bearing members 21 and 21 are integrally formed by being connected by a connecting portion 21a. A shaft member 22 is installed between the bearing members 21 and 21, and the upper end of the second link member 9 is rotatably attached to the shaft member 22. That is, the upper end of the second link member 9 is connected to the link shafts 6 and 6 via the bearing members 21 and 21.

[0026] The first link member 8, the second link member 9, and the lower end of the first link member 8 that are parallel to each other are pivoted. The shaft 11 that attaches, the shaft 12 that pivots the lower end of the second link member 9, and the link shaft 6 that connects the upper end of the first link member 8 and the second link member 9 constitute a four-bar linkage mechanism 5. The four-bar linkage mechanism 5 constitutes the arm 3.

A tension spring 7 is stretched between the upper part of the second link member 9 and the lower part of the first link member 8. The upper end of the tension spring 7 may be attached to the force attached to the shaft member 22 provided at the upper end of the second link member 9 or the locking member 23. 2, FIG. 3, FIG. 4 and FIG. 8 show the case where the shaft member 22 is attached, and FIGS. 6 and 7 show the case where the shaft member 22 is attached. Further, the lower end of the tension spring 7 is provided with a mounting portion 24 in the lower part of the first link member 8 in this example, and the force S attached to this mounting portion 24 may be the shaft 11. The tension spring 7 is disposed in the space between the first link member 8 and the second link member 9 described above. In this example, two tension springs 7 are stretched. As a result, the first link member 8 and the second link member 9 are formed of a plate-like body, and the tension spring 7 is built in the space between the first link member 8 and the second link member 9. Therefore, the thickness of the arm 3 formed by the link mechanism 5 can be reduced and slimmed, and the tension spring 7 is protected by the first and second link members 8 and 9 and other members. Interference from other parts is also prevented.

[0027] Since the tension spring 7 is mainly balanced against the rotational moment due to the weight of the display panel 1, the spring force of the tension spring 7 and the tension spring 7 corresponding to the rotational moment due to the weight of the display panel 1 are adjusted. By setting the number, etc., the height of the display panel 1 can be adjusted with light force, improving operability and optimizing the balance characteristics.

Fig. 11 shows the weight moment Mw when the display panel is placed at the arm angle displacement (deg) and the balance spring moment Ms generated by the spring reaction force built into the arm.

The closer the spring moment Ms is to the display panel weight moment Mw, the better the balance characteristics in the operating range, the better the operability, and the lower the display panel height can be adjusted. Therefore, the tension spring 7 is preferably set so as to have a spring moment Ms as shown in FIG.

[0028] It should be noted that, as the spring that counteracts the rotational moment due to the weight of the display panel 1, the above-described implementation is performed. In the form of the force shown in the case of the tension spring 7, this may be another spring. For example, a compression spring, a disc spring, a ring spring, etc. can be illustrated.

FIG. 14 is an explanatory side view when the compression spring 7a is used. In the case of the compression spring 7a, the lower end of the compression spring 7a is connected to the lower end of the second link member 9, and the upper end of the compression spring 7a is connected to the upper end of the first link member 8. As a result, when the arm 3 (link members 8 and 9) rotates downward (in the direction of lowering the height of the display panel 1), the compression spring 7a is compressed and its repulsive force (spring force) increases. To counter the rotational moment due to the weight of the display panel. The arrow indicates the biasing direction of the compression spring.

In addition, a disc spring or a ring spring is formed by stacking a plurality of disc springs or ring springs in a stacked manner, and this is used in the same manner as the compression spring. In the case of this disc spring or ring spring, an auxiliary tool is required to maintain the state in which the disc springs and ring springs are arranged in an overlapping manner.

Next, the operation of the display panel support device shown in the embodiment will be described.

The first link member 8 and the second link member 9 of the link mechanism 5 constituting the arm 3 are pivotally attached to the bracket 10 of the base 2 so that the lower end of the first link member 8 and the second link member 9 can rotate about the shafts 11 and 12. The upper end of the first link member 8 is connected to a link shaft 6 provided at the upper end of the first link member 8 by a shaft member 22 via a bearing member 21, and a friction mechanism 15 is connected to the link shaft 6 at the upper end of the first link member 8. The display panel mounting frame 4 is pivotably mounted through the display panel mounting frame 4, and the display panel 1 is mounted on the display panel mounting frame 4. A tension spring 7 is stretched between the upper part of the second link member 9 and the lower part of the first link member 8.

Accordingly, the display panel 1 attached to the display panel mounting frame 4 has the arm 3 constituted by the link mechanism 5 as shown in FIG. 2 and the shafts 11 and 1 2 of the first and second link members 8 and 9. It can be moved up and down by rotating around the center, and the height can be adjusted. When this height is adjusted, the tension spring 7 of the link mechanism 5 balances against the rotational moment mainly due to the weight of the display panel 1, so it can move up and down with a light force and remove the light force (external force). And stop at that position (balanced still). That is, the free stop is performed. In short, the height of the display panel can be adjusted with a light force. In this adjustment of the height of the display panel 1, the arm 3 is composed of the link mechanism 5! /, So the tilt angle of the display panel 1 does not change! /.

In addition, the display panel 1 has a display panel mounting frame 4 and a link shaft 6 as shown in FIG. The tilt angle can be adjusted by pivoting to the center. The display panel mounting frame 4 is attached to the link shaft 6 with a friction mechanism 15 interposed therebetween. Therefore, the display panel mounting frame 4 can be rotated by applying a force greater than the resistance force (friction resistance) of the friction mechanism 15. If the external force is removed, it can be adjusted and stopped at that position by the resistance force (friction resistance) of the friction mechanism 15, and the posture is maintained.

[0031] At this time, the adjustment range of the inclination angle of the display panel 1 is restricted by the operating range of the display panel mounting frame 4 because the locking plate 19 is pressed by the spring 20 and is positioned in the notch 18a of the stopper plate 18. The adjustment (operation) range is within the length of the notch 18a. However, if the locking plate 19 is slid against the spring 20 and is removed from the notch 18a of the staggered plate 18, the operating range of the display panel mounting frame 4 is widened and can be folded as shown in FIG. .

That is, the display panel mounting frame 4 is rotated in the direction of arrow X in FIG. 2 with the display panel mounting frame 4 in the above state, and the arm 3 constituted by the link mechanism 5 is rotated in the direction of arrow Y in FIG. Therefore, it can be folded as shown in FIG. 12 shows the state where the display panel mounting frame 4 is rotated to the horizontal position, and FIG. 13 shows the state where the display panel mounting frame 4 is further rotated and the arm 3 is also rotated and folded. You can understand how you can fold it.

[0033] The display panel mounting frame 4 has a besa (plate) to which the display panel 1 can be mounted and a base, and the besa is a pivot mechanism and a base that can convert the display panel 1 into a horizontal orientation and a vertical orientation. Is a force provided with a swivel mechanism that can rotate the display panel 1 in a left-right direction.

The base 2 is also preferably rotatable. A conventionally well-known structure can be adopted to make the base 2 rotatable.

It should be noted that the above embodiment is not intended to limit the present invention, and various modifications are allowed within the scope of the present invention. For example, the link mechanism 5 may be another link mechanism, and may be another spring instead of the tension spring 7.
