Description

[Technical Field]

[0001] This invention relates to a two-axis rotating TV stand. [Background technology]

[0002] There are several conventional technologies related to stands that change the position and orientation of a television. Here, a television stand refers to a support device that is provided separately from the television and changes the position and orientation of the television's display unit (screen) to adjust the ease of viewing the television.

[0003] For example, Japanese Patent Application Laid-Open Publication No. 2017-194664 (Patent Document 1) discloses a stand used to hold a display device. Here, the stand includes a base portion and a support portion that rotates relative to the base portion and holds the display device. The support portion also includes a drive unit for rotating the display screen of the display device, and the drive unit is provided on the back side of the display screen of the display device. This reduces design restrictions on the base portion.

[0004] Furthermore, Japanese Patent Application Laid-Open Publication No. 2022-47417 (Patent Document 2) discloses a television position adjustment device. Here, the television position adjustment device includes a base, a pair of left and right guide rails, and a moving body. The pair of left and right guide rails are supported by the base and extend upward, extending forward at least partway in an arched shape. The moving body is guided by the left and right guide rails, respectively, and is movable in the extension direction of the guide rails, and is attached to the television. As a result, it is possible to automatically position the television in the optimal orientation and height simply by moving the position of the television along the guide rails.

[0005] Furthermore, Japanese Patent Application Laid-Open Publication No. 2023-47617 (Patent Document 3) discloses an upright lift-up TV stand including a support frame, a cylinder, and an assembly frame. The support frame has a base at its bottom, an outer support tube disposed at the top end of the base, and an inner support tube movably fitted within the outer support tube. The cylinder is disposed within the outer support tube of the support frame, and the bottom of the cylinder is connected and fixed to the base, and the upper end of the cylinder's output shaft is assembled and fixed to the upper end of the inner support tube. A control member corresponding to the output shaft is provided at the upper end of the inner support tube, and the control member controls the movement of the cylinder's output shaft. The assembly frame has a rotation shaft at its bottom, and the rotation shaft is connected and fixed to the top end of the cylinder's output shaft via a shaft sleeve. The assembly frame is rotatable about the rotation shaft, and the rear of the TV is attached to the front end of the assembly frame. This allows the user to adjust the height quickly and easily to the desired height without using tools, and the height can be adjusted in a stepless manner, and the angle can also be adjusted in the direction of the view.

[0007] Currently, there are TV displays on the market that move back and forth, or rotate clockwise or counterclockwise, but there is no technology that combines both. Therefore, there has been a demand for a TV display that moves in two different directions, rather than a TV display that moves in one direction.

[0008] For example, for a user to watch while lying down, it is preferable that the display unit of the television can be rotated clockwise or counterclockwise, but it is not sufficient for the display unit of the television to simply move back and forth.For a user to watch while sitting on a sofa, it is preferable that the display unit of the television can be rotated back and forth, but it is not sufficient for the display unit of the television to simply rotate clockwise or counterclockwise.

[0009] The technologies described in the above-mentioned Patent Documents 1 to 3 only allow the television display unit to move forward and backward, or to rotate clockwise or counterclockwise, and are not capable of operating in two directions.

[0010] Furthermore, when the television display unit operates in one direction, it is preferable that the television display unit be easy to position and that it be simple for the user to operate. However, with the above-mentioned technology, it is difficult to position the television display unit and the operation of the television display unit is complicated, so there was a demand for a product that is easy for the user to operate.

[0011] Therefore, the present invention has been made to solve the above problem, and its object is to provide a two-axis rotating TV stand that allows the TV display to be easily changed in two directions. [Means for solving the problem]

[0012] The two-axis rotatable TV stand according to the present invention comprises a support plate, an outer tube, multiple circular openings, an elliptical opening, an inner tube, a ball, a positioning portion, a U-shaped portion, a shaft, and a support portion. The support plate is plate-shaped and shaped to correspond to the rear of a television and is fixed to the rear of the television. The outer tube is cylindrical, with one end fixed near the center of the support plate and the other end open. The multiple circular openings are opened at predetermined intervals along the outer periphery of the outer tube, and the elliptical opening is opened along the outer periphery of the outer tube for a predetermined length. The inner tube is cylindrical, with one end rotatably attached to the inside of the outer tube and the other end extending beyond the other end of the outer tube by a predetermined length. The ball portion is retractably mounted on the outer periphery of the inner cylindrical portion attached to the outer cylindrical portion at a position corresponding to the central circular opening of the outer cylindrical portion, and can be attached to any of the circular openings of the outer cylindrical portion. The positioning portion is columnar and fixed to the outer periphery of the inner cylindrical portion attached to the inner cylindrical portion at a central position of the elliptical opening of the outer cylindrical portion through the elliptical opening, and the U-shaped portion is arranged in an arc shape relative to the protruding portion at the other end of the inner cylindrical portion. The shaft portion is long and cylindrical and passes through both ends of the U-shaped portion and the protruding portion at the other end of the inner cylindrical portion to rotatably support the U-shaped portion relative to the inner cylindrical portion. The support portion has an upper end fixed near the center of the U-shaped portion and a lower end placed on the ground. [Effects of the Invention]

[0013] According to this invention, the display of the TV can be easily changed between two directions. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] The following describes embodiments of the present invention with reference to the accompanying drawings to help understand the present invention. Note that the following embodiments are examples of the present invention and are not intended to limit the technical scope of the present invention.

[0016] As shown in FIG. 1, the two-axis rotating TV stand 1 of the present invention comprises a support plate 10, an outer tube portion 11, a plurality of circular openings 12, an oval opening 13, an inner tube portion 14, a ball portion 15, a positioning portion 16, a U-shaped portion 17, an axis portion 18, and a support portion 19.

[0017] Here, the support plate 10 (bracket) is formed in a plate shape, has a shape corresponding to the shape of the rear surface 20 of the television 2, and is fixed to the rear surface 20 of the television 2. Here, since the shape of the rear surface 20 of the television 2 is determined by the model number and type of the television 2, it is preferable to manufacture the support plate 10 according to the model number and type of the television 2, for example.

[0018] The outer tube portion 11 is cylindrical, with one end 11a fixed to the center 10a of the support plate 10 and the other end 11b open. The support plate 10 is fixed to the four corners of the rear surface 20 of the television 2 with fixing portions 10b such as screws.

[0019] Here, if the back surface 20 of the television 2 is flat, the support plate 10 can be fixed to the back surface 20 of the television 2 at the four corners with the fixing parts 10b. However, if the back surface 20 of the television 2 has a convex shape such as a trapezoidal shape depending on the model number or type of the television 2, the support plate 10 can be fixed to the back surface 20 of the television 2 by providing a spacer in addition to the fixing parts 10b or by extending the length of the fixing parts 10b.

[0020] Furthermore, the multiple circular openings 12 are opened at a predetermined interval I on the outer periphery of the outer tubular portion 11 along the outer circumferential direction of the outer tubular portion 11. Here, three circular openings 12 are provided. Furthermore, the elliptical opening 13 is opened at a predetermined length L1 on the outer periphery of the outer tubular portion 11 along the outer circumferential direction of the outer tubular portion 11.

[0021] Furthermore, the inner tube portion 14 is cylindrical, with one end 14a rotatably attached to the inside of the outer tube portion 11 from the other end 11b of the outer tube portion 11, and the other end 14b protruding from the other end 11b of the outer tube portion 11 by a predetermined length L2. By configuring the outer tube portion 11 to be rotatable relative to the inner tube portion 14 with the inner tube portion 14 attached to the outer tube portion 11, manufacturing is simplified, and the rotation axis becomes the central axis in the longitudinal direction of the inner tube portion 14, allowing the display portion of the television 2 to be rotated easily without the rotation axis being complicated.

[0022] Furthermore, the ball portion 15 is provided on the outer periphery of the inner cylindrical portion 14 attached to the outer cylindrical portion 11 so as to be able to move in and out at a position corresponding to the circular opening 12 located in the middle of the plurality of circular openings 12 of the outer cylindrical portion 11, and can be attached to any of the plurality of circular openings 12 of the outer cylindrical portion 11. Here, by rotating the inner cylindrical portion 14 to the right relative to the outer cylindrical portion 11, the ball portion 15 will, for example, move out of the middle circular opening 12 and enter the right circular opening 12 and become fixed. On the other hand, by rotating the inner cylindrical portion 14 to the left relative to the outer cylindrical portion 11, the ball portion 15 will, for example, move out of the middle circular opening 12 and enter the left circular opening 12 and become fixed. By providing this ball portion 15, the outer tube portion 11 can rotate freely relative to the inner tube portion 14, but if the user wants to fix the display unit of the television 2 at a predetermined rotation angle, the ball portion 15 can be attached to the circular opening 12 of the outer tube portion 11 at the desired rotation angle, thereby easily fixing the display unit of the television 2 at the predetermined rotation angle.

[0023] Furthermore, the positioning portion 16 is fixed to the outer periphery of the inner tube portion 14 attached to the inner tube portion 14 at a position in the middle of the elliptical opening 13 of the outer tube portion 11, through the elliptical opening 13. This allows the outer tube portion 11 to rotate freely relative to the inner tube portion 14, while the positioning portion 16 moves in a sliding manner within the elliptical opening 13, thereby appropriately guiding the rotation of the outer tube portion 11 and allowing the user to appropriately rotate the display portion of the television 2.

[0024] The U-shaped portion 17 is disposed in an arc shape relative to the protruding portion 14c of the other end 14b of the inner cylindrical portion 14. The shaft portion 18 is formed in a long cylindrical shape and is inserted through openings 17b at both end portions 17a of the U-shaped portion 17 and openings 14c at the protruding portion of the other end 14b of the inner cylindrical portion 14, thereby rotatably supporting the U-shaped portion 17 relative to the inner cylindrical portion 14. Fixing portions 18a are provided at both end portions of the shaft portion 18, and the protruding portion of the other end 14b of the inner cylindrical portion 14 is rotatably fixed to both end portions 17a of the U-shaped portion 17 with the shaft portion 18 serving as a rotation axis. As a result, the rotation axis of the inner tube portion 14 relative to the outer tube portion 11 and the rotation axis of the inner tube portion 14 relative to the U-shaped portion 17 are perpendicular to each other, making it possible for the U-shaped portion 17 to rotate relative to the inner tube portion 14 on a rotation axis different from that of the outer tube portion 11, and allowing the display portion of the television 2 to rotate in two different directions.

[0025] Furthermore, the upper end 19a of the support part 19 is fixed near the center of the U-shaped part 17, and the lower end 19b is placed on the ground. Here, as shown in Fig. 1, the support part 19 is configured as a tripod with three legs, and the lower end 19b, which is located close to the rear surface 20 of the television 2, is bent into an L-shape, so that even if the display part of the television 2 rotates clockwise or counterclockwise with respect to the inner tube part 14, the support part 19 can support the television 2 without coming into contact with the lower end 19b of the support part 19.

[0026] Here, we will explain the method of attaching the inner cylindrical portion 14 to the outer cylindrical portion 11. As shown in Figure 2, first, multiple circular openings 12 and an elliptical opening 13 are provided in the outer cylindrical portion 11. Next, the inner cylindrical portion 14 is provided with a ball portion 15, an opening 14c in the protruding portion of the other end 14b of the inner cylindrical portion 14, and an attachment portion 16a (e.g., a female screw portion) to which the positioning portion 16 can be attached.

[0027] Here, the ball portion 15 of the inner cylindrical portion 14 has a cylindrical portion 15a whose tip portion 15b is reduced in diameter, a spherical body 15c is held at the tip portion 15b, and a spring 15d is provided inside the cylindrical portion 15a. The restoring force of this spring 15d urges a part of the spherical body 15c in a direction that protrudes from the tip portion 15b.

[0028] When one end 14a of the inner cylindrical portion 14 is attached to the other end 11b of the outer cylindrical portion 11, the ball portion 15 of the inner cylindrical portion 14 is exposed from the circular opening 12 of the outer cylindrical portion 11, temporarily fixing the inner cylindrical portion 14 to the outer cylindrical portion 11, and the attachment portion 16a of the inner cylindrical portion 14 is exposed from the elliptical opening 13. Then, by attaching the male thread portion of the positioning portion 16 to the female thread portion of the attachment portion 16a, the positioning portion 16 fits along the elliptical opening 13, and the inner cylindrical portion 14 is attached to the outer cylindrical portion 11 so that it can rotate.

[0029] 3, when the ball portion 15 is attached to the middle circular opening 12 among the multiple circular openings 12, rotating the outer cylindrical portion 11 to the left relative to the inner cylindrical portion 14 guides the positioning portion 16 to the left end of the elliptical opening 13 of the outer cylindrical portion 11, and the ball portion 15 is attached to the left circular opening 12. When the outer cylindrical portion 11 is rotated to the right relative to the inner cylindrical portion 14, the positioning portion 16 is guided to the right end of the elliptical opening 13 of the outer cylindrical portion 11, and the ball portion 15 is attached to the right circular opening 12.

[0030] 3, a plurality of claw portions 11c protruding outward can be provided at one end 11a of the outer cylindrical portion 11, and a plurality of claw receivers 10c for receiving the claw portions 11c can be provided in the support plate 10 near the center 10a where the one end 11a of the outer cylindrical portion 11 is fixed, corresponding to the number and positions of the claw portions 11c, and the claw portions 11c of the outer cylindrical portion 11 can be hooked onto the claw receivers 10c of the support plate 10, thereby fixing the outer cylindrical portion 11 to the support plate 10. Here, a plurality of claw portions 11c are provided at predetermined intervals along the circumferential direction of the one end 11a of the outer cylindrical portion 11, and a plurality of claw receivers 10c are provided at predetermined intervals corresponding to the number of the claw portions 11c. As a result, the claw portions 11c and the claw receiving portions 10c can be provided externally to the outer tube portion 11 and the support plate 10, respectively, and therefore the outer tube portion 11 can be easily fixed to the support plate 10. Furthermore, the outer tube portion 11 can be easily connected to the support plate 10 simply by inserting the claw portions 11c into the claw receiving portions 10c, and therefore the outer tube portion 11 can be easily fixed manually to the support plate 10. Furthermore, if the inserted claw portions 11c are welded to the claw receiving portions 10c, the outer tube portion 11 can be reliably fixed to the support plate 10.

[0031] Here, the lower end 19b of the support part 19 may be configured as a tripod, or as shown in Fig. 4, may be configured as a support pillar that is inclined from below the television 2 along the rear surface 20 of the television 2. This allows the support part 19 to support the television 2 without coming into contact with the lower end 19b of the support part 19, even if the display part of the television 2 rotates clockwise or counterclockwise relative to the inner cylinder part 14.

[0032] As a result, the biaxially rotating TV stand 1 can easily change the direction of the display unit of the TV 2. That is, the biaxially rotating TV stand 1 can rotate the display unit of the TV 2 clockwise or counterclockwise relative to the inner cylinder part 14 by rotating the inner cylinder part 14 relative to the outer cylinder part 11.

[0033] Therefore, for example, when a user holds the support plate 10 or the outer tube portion 11 and rotates the display portion of the television 2 to the left relative to the inner tube portion 14 (support portion 19) as viewed from the display portion of the television 2, the display portion of the television 2 can be rotated to the left as shown in Fig. 5. At that time, the positioning portion 16 is guided to the left end of the oval opening 13 of the outer tube portion 11, and the ball portion 15 is attached to the circular opening 12 on the left side.

[0034] Now, for example, if a user holds the support plate 10 or the outer tube portion 11 and rotates the display portion of the television 2 to the right relative to the inner tube portion 14 (support portion 19) as viewed from the display portion of the television 2, the display portion of the television 2 can be rotated to the right, as shown in Fig. 6. At that time, the positioning portion 16 is guided to the right end of the oval opening 13 of the outer tube portion 11, and the ball portion 15 is attached to the right circular opening 12. In this way, by moving the ball portion 15 in and out of one of the multiple circular openings 12, the user can position the display portion of the television 2 at a desired rotation angle.

[0035] Furthermore, the two-axis rotating television stand 1 can rotate the display section of the television 2 back and forth relative to the U-shaped section 17 by rotating the U-shaped section 17 relative to the inner cylindrical section 14 via the shaft section 18.

[0036] Therefore, for example, when a user grasps the axis portion 18 (fixing portion 18a, support portion 19) and rotates the display portion of the television 2 forward relative to the U-shaped portion 17 (support portion 19) when viewed from the display portion of the television 2, the display portion of the television 2 can be rotated forward as shown in Figure 7.

[0037] Now, for example, if a user holds the axis portion 18 (fixing portion 18a, support portion 19) and rotates the display portion of the television 2 backward relative to the U-shaped portion 17 (support portion 19) when viewed from the display portion of the television 2, the display portion of the television 2 can be rotated backward as shown in Figure 8.

[0038] In this way, the present invention allows the user to easily change the display direction of the television 2 between two directions. For example, if the user wants to watch the television 2 while lying on their side, the user can hold the support plate 10 or the outer tube portion 11 and rotate the display direction of the television 2 to the right relative to the inner tube portion 14 (support portion 19) as seen from the display direction of the television 2. As shown in Figure 9, this allows the vertical direction of the display direction of the television 2 to correspond to the vertical direction of the user lying on their side, allowing the user to view the television 2 properly even when lying on their side. Note that even if the user lies on their side in the opposite direction, the same effect can be achieved by rotating the display direction of the television 2 in the opposite direction.

[0039] Furthermore, for example, if a user wants to watch television 2 while sitting on a sofa, the user will tend to lean forward, so by grasping axis 18 and rotating the display unit of television 2 forward relative to U-shaped portion 17 (support portion 19) as viewed from the display unit of television 2, the tilt of the display unit of television 2 can be adjusted to correspond to the tilt of the user sitting on the sofa, as shown in Fig. 10, allowing the user to properly watch television 2 even while sitting on the sofa. Note that even if the user is sitting on the sofa leaning backward, the same effect can be achieved by rotating the display unit of television 2 backward in the opposite direction to that described above.

[0040] Furthermore, this device allows the display unit of the television 2 to be rotated in two directions simultaneously. For example, if the user rotates the display unit of the television 2 to the right relative to the inner tube portion 14 (support portion 19) and rotates the display unit of the television 2 backward relative to the U-shaped portion 17 (support portion 19), the user can view the display unit of the television 2 while lying on their side and looking up. In other words, by rotating the display unit of the television 2 in two directions, the user can rotate the display unit of the television 2 to a direction that is easy to view from various angles, thereby increasing user convenience. Furthermore, the rotation mechanism is simplified, improving user operability.

[0041] Here, the shape of the support plate 10 is not particularly limited, but examples thereof include a rectangle and an H-shape. Furthermore, the material of the support plate 10 is not particularly limited, but examples thereof include aluminum, iron, stainless steel, ABS resin, polycarbonate, wood, composite materials, etc. Furthermore, the size of the support plate 10 is not particularly limited, but it can be changed according to the size of the television.
