Description

Technical Field

[0001] The present invention relates to a bracket, and in particular to a display bracket and a display device thereof. Background Art

[0002] Monitors are a very common electronic device. During use, they are typically mounted on a support frame to maintain their position. Furthermore, to allow the monitor to be freely adjusted to suit different usage requirements, a movable structure is typically installed between the support frame and the monitor, allowing the monitor to adjust its angle or distance from the support frame.

[0003] However, during the process of adjusting the position of the monitor, if the support bracket is installed on a non-fixed object (such as a base placed on a table), the base is prone to shaking or tipping over during the monitor adjustment process, resulting in the support bracket having to be installed on a fixed object, thereby limiting the application range of the support bracket. Summary of the Invention

[0004] An object of the present invention is to provide a display stand and a display device thereof to solve at least one of the above problems.

[0005] In view of the above, in one embodiment, a display stand is provided, comprising a hollow column, a connecting assembly, and a movable arm. The hollow column comprises a top end, a bottom end, and a receiving space, wherein an elastic member and a movable member are disposed in the receiving space. The connecting assembly comprises a hollow connecting arm, a linking member, and a positioning member. The hollow connecting arm comprises a first end, a second end, and an internal space. The first end is connected to the hollow column and adjacent to the top end, and the second end is spaced away from the top end relative to the first end. The internal space is connected to the receiving space. The linking member and the positioning member are movably disposed in the internal space, with one end of the linking member adjacent to the second end and the other end of the linking member extending into the receiving space. The movable member is located between the elastic member and the linking member. The movable arm comprises a third end and a fourth end. The third end is provided with a pivot member having a supporting portion, and the fourth end is provided with a display assembly portion. The movable arm is pivotally mounted to the second end of the hollow connecting arm via the pivot member, so that the movable arm can selectively rotate relative to the hollow connecting arm between an extended position and a retracted position. When the movable arm rotates from the extended position to the retracted position, the abutting portion of the pivoting member abuts the linking member to move relative to the hollow connecting arm, so that the linking member drives the movable member to press the elastic member and the positioning member to lock the movable arm.

[0006] In another embodiment, a display device is provided, comprising the aforementioned display stand and a display, wherein the display has a front surface and a back surface, and the back surface is assembled to the display assembly portion of the display stand.

[0007] In summary, when the movable arm of the monitor stand of the embodiment of the present invention is in the extended position, the movable arm is in a freely rotatable state, allowing the hollow column of the monitor stand to be optionally mounted on a fixed object (such as a desk clamp). When the movable arm is rotated from the extended position to the retracted position, the positioning member locks the movable arm into a locked state through the action of the pivoting member, the linkage member, and the movable member. This allows the hollow column of the monitor stand to be optionally mounted on a non-fixed object (such as a base placed on a table). This allows the monitor stand to freely switch between two different states, allowing the monitor to be adapted for different types of objects without having to replace the monitor stand.

[0061] like Figure 1 FIG. 1 is an embodiment of a display device D according to the present invention, comprising a display stand 1 and a display 100, wherein the display 100 is mounted on the display stand 1. In some embodiments, the display 100 may be a plasma display, a liquid crystal display, a light emitting diode display, or other flat panel displays.

[0062] like Figures 1 to 4 As shown, the monitor stand 1 includes a hollow column 10, a connecting assembly 20, and a movable arm 30. The hollow column 10 includes a top end 11, a bottom end 12, and an accommodating space 13. The top end 11 and the bottom end 12 are the two opposite ends of the hollow column 10. In this embodiment, the hollow column 10 is a circular hollow cylinder, and the hollow column 10 is used to be fixed to an object, such as a table, a wall, or a floor.

[0063] In some embodiments, the hollow column 10 may also be a column of other shapes (such as square, rectangular or oval). In addition, the hollow column 10 may be arranged upright (such as Figure 1 as shown) or tilted setting.

[0064] like Figures 2 to 5 As shown, an elastic member 14 and a movable member 15 are disposed within the receiving space 13 of the hollow column 10. The movable member 15 can move relative to the hollow column 10 to compress or release the elastic member 14. For example, the movable member 15 can be pivotally mounted within the receiving space 13, allowing the movable member 15 to rotate and swing relative to the hollow column 10. Alternatively, the movable member 15 can be mounted within the receiving space 13 via other guide structures (such as slide rails or guide grooves), allowing the movable member 15 to slide relative to the hollow column 10.

[0065] like Figures 2 to 5As shown, in this embodiment, the top end 11 of the hollow column 10 is provided with a top plate 111, and the bottom end 12 of the hollow column 10 is provided with a bottom plate 122. The movable member 15 is an elongated rod extending from the top end 11 to the bottom end 12, wherein the movable member 15 has a pivot 151, one end of the pivot 151 is pivoted to the top plate 111, and the other end of the pivot 151 is pivoted to the bottom plate 122, so that the movable member 15 can rotate and swing relative to the hollow column 10 with the pivot 151 as the axis.

[0066] like Figures 2 to 5 As shown, the elastic member 14 within the accommodating space 13 of the hollow column 10 can be made of an elastic material. Elasticity refers to the ability of a material to deform upon application of an external force and to return to its original shape upon removal of the external force. For example, the elastic member 14 can be an elastomer such as a spring, a spring, or elastic rubber. In this embodiment, a fixed seat 18 and a slider 19 are provided on the bottom plate 122 of the bottom end 12 of the hollow column 10. The slider 19 is slidably connected to the fixed seat 18. The elastic member 14 is disposed within the fixed seat 18 and abuts against the slider 19. Thus, when the movable member 15 moves relative to the hollow column 10, the movable member 15 can press the slider 19 to slide relative to the fixed seat 18, thereby compressing or releasing the elastic member 14 via the slider 19.

[0067] like Figures 2 to 5 As shown, the connecting assembly 20 includes a hollow connecting arm 21, a linkage 25, and a positioning member 26. The hollow connecting arm 21 has a first end 22, a second end 23, and an internal space 24. The first end 22 is connected to the hollow column 10 and is adjacent to the top end 11. The second end 23 is farther away from the top end 11 than the first end 22. The internal space 24 of the hollow connecting arm 21 is connected to the accommodating space 13 of the hollow column 10. In this embodiment, the hollow connecting arm 21 is a horizontal hollow cylinder and is perpendicular to the hollow column 10. The second end 23 of the hollow connecting arm 21 maintains a distance from the hollow column 10. The distance depends on the length of the hollow connecting arm 21. In other words, the longer the hollow connecting arm 21 is, the greater the distance between the second end 23 and the hollow column 10.

[0068] like Figures 2 to 5 As shown, the linkage member 25 and the positioning member 26 of the connecting assembly 20 are respectively movably disposed in the internal space 24. In this embodiment, the linkage member 25 is a long rod, one end of the linkage member 25 is adjacent to the second end 23, and the other end of the linkage member 25 extends into the accommodating space 13 of the hollow column 10. The movable member 15 in the accommodating space 13 is located between the elastic member 14 and the end of the linkage member 25, and the linkage member 25 can slide laterally relative to the hollow connecting arm 21 to drive the movable member 15 to move relative to the hollow column 10 to press or release the elastic member 14.

[0069] like Figure 2 and Figure 6As shown, in this embodiment, the positioning member 26 of the connecting assembly 20 is pivoted on the hollow connecting arm 21, so that the positioning member 26 can rotate and swing relative to the hollow connecting arm 21, wherein the positioning member 26 includes a first pivot portion 261 and a second pivot portion 262, the first pivot portion 261 is a pivot and is pivoted on the hollow connecting arm 21, and the second pivot portion 262 is an axial hole and is pivoted on the connecting member 25. Here, the connecting member 25 has a shaft 251, which passes through the second pivot portion 262, so that the second pivot portion 262 is pivoted on the connecting member 25. Therefore, when the connecting member 25 slides relative to the hollow connecting arm 21, the shaft 251 of the connecting member 25 can push the positioning member 26 to rotate and swing relative to the hollow connecting arm 21 with the first pivot portion 261 as the axis.

[0070] like Figure 2 、 Figures 5 to 8 As shown, the movable arm 30 has a third end 31 and a fourth end 35. The third end 31 is provided with a pivot member 32. The movable arm 30 is pivotally mounted on the second end 23 of the hollow connecting arm 21 by the pivot member 32, so that the movable arm 30 can be rotated relative to the hollow connecting arm 21 to an extended position (such as Figure 5 The position shown) and a folded position (as shown Figure 7 The fourth end 35 of the movable arm 30 is provided with a display assembly portion 351 for attaching the display 100. The display 100 has a front face 110 and a back face 120. The back face 120 of the display 100 and the display assembly portion 351 can be connected by snapping, pivoting, or locking. Thus, a user can operate the movable arm 30 to rotate relative to the hollow connecting arm 21 to adjust the angle or position of the display 100 as needed.

[0071] like Figure 2 and Figure 5 As shown, the pivot member 32 at the third end 31 of the movable arm 30 further has a supporting portion 321. In this embodiment, the pivot member 32 is a sleeve that is sleeved around the third end 31 of the movable arm 30. The supporting portion 321 is a protrusion (here, a boss) provided around the pivot member 32. When the movable arm 30 rotates relative to the hollow connecting arm 21, the pivot member 32 can rotate synchronously. In some embodiments, the pivot member 32 can also be integrally formed at the third end 31 of the movable arm 30, but this is not limited to this.

[0072] like Figure 5 and Figure 6 As shown, in this embodiment, the movable arm 30 is in the above-mentioned extended position. When the movable arm 30 is in the extended position, the movable arm 30 and the hollow connecting arm 21 are not parallel to each other, and the movable arm 30 can freely rotate relative to the hollow connecting arm 21 to adjust the angle or position of the display 100. When the movable arm 30 is in the state of being freely rotatable, the display stand 1 can be optionally assembled to a fixed object, such as Figure 10 As shown, the bottom end 12 of the hollow column 10 of the monitor stand 1 is assembled on a table clamp 50, and the table clamp 50 is fixed to the table top, so that when the movable arm 30 is rotated to adjust the position of the monitor 100, the table clamp 50 will not shake or detach due to force.

[0073] In addition, if Figure 5 and Figure 6 As shown, when the movable arm 30 is in the unfolded position, the positioning member 26 is entirely located in the inner space 24 of the hollow connecting arm 21. Figure 5 and Figure 7 As shown, when the movable arm 30 swings from the unfolded position toward the hollow connecting arm 21 (as shown in FIG. Figure 5 L) to the folded position (as shown by the arrow L) Figure 7 During the process of moving the movable arm 30 to the retracted position (as shown in FIG1 ), the abutting portion 321 of the pivoting member 32 abuts the end portion of the linking member 25 adjacent to the second end 23, causing the linking member 25 to move toward the hollow column 10, so that the end portion of the linking member 25 located in the accommodating space 13 abuts the movable member 15, thereby driving the movable member 15 to rotate and press the elastic member 14. When the movable arm 30 rotates to the retracted position (as shown in FIG1 ), the abutting portion 321 of the pivoting member 32 abuts the end portion of the linking member 25 adjacent to the second end 23, causing the linking member 25 to move toward the hollow column 10, thereby causing the linking member 25 to push the movable member 15 at the end portion of the accommodating space 13, thereby driving the movable Figure 7 and Figure 8 The movable arm 30 and the hollow connecting arm 21 are stacked on top of each other.

[0074] Please check again Figure 6 and Figure 8 As shown, when the movable arm 30 swings from the unfolded position (as shown in FIG. Figure 5 In the process of moving from the hollow connecting arm 21 to the folded position (as shown by the arrow L), when the linking member 25 moves toward the direction of the hollow column 10, the linking member 25 will simultaneously drive the positioning member 26 to move relative to the hollow connecting arm 21 (here, a swinging movement), and when the movable arm 30 swings to the folded position (as shown by the arrow L), the positioning member 26 will move relative to the hollow connecting arm 21 (here, a swinging movement). Figure 7 and Figure 8 The positioning member 26 can lock the movable arm 30 so that the movable arm 30 can no longer rotate relative to the hollow connecting arm 21. When the movable arm 30 is in the folded position and locked, the display stand 1 can be optionally assembled to a non-fixed object, such as Figure 1 and Figure 3 As shown, the bottom end 12 of the hollow column 10 of the display stand 1 is assembled on a base 40, and the base 40 is placed on the table and is in a non-fixed state, so as to prevent the movable arm 30 from being moved under force and causing the base 40 to shake or fall.

[0075] Please check again Figure 6 and Figure 8 As shown, the bottom of the movable arm 30 also has a buckle groove 301, and the top of the hollow connecting arm 21 has an opening 211 (as shown in FIG. Figure 2 As shown), when the movable arm 30 is moved from the unfolded position (as shown Figure 6 As shown) rotate to the folded position (as shown) Figure 8 As shown), the positioning member 26 can be driven by the linkage member 25, so that part of the positioning member 26 passes through the opening 211 and extends into the buckle groove 301, so as to lock the movable arm 30 through the positioning member 26.

[0076] In summary, when the movable arm 30 of the monitor stand 1 of the embodiment of the present invention is in the extended position, the movable arm 30 is in a freely rotatable state, allowing the hollow column 10 of the monitor stand 1 to be optionally mounted on a fixed object (such as a desk clamp 50). When the movable arm 30 is rotated from the extended position to the retracted position, the positioning member 26 can be locked to the movable arm 30 through the actuation of the pivot member 32, the linkage member 25, and the movable member 15. This allows the hollow column 10 of the monitor stand 1 to be mounted not only on a fixed object but also on a non-fixed object (such as a base 40 placed on a table). This allows the monitor stand 1 to freely switch between two different states (i.e., the freely rotatable state and the locked state), allowing the monitor 100 to be mounted on different types of objects without having to replace the monitor stand 1.

[0077] like Figure 7 As shown, the display assembly portion 351 of the movable arm 30 is a bent rod to form a receiving groove 302. For example, in this embodiment, the display assembly portion 351 is an arc-shaped rod to form an arc-shaped receiving groove 302, so that the receiving groove 302 can match the edge shape of the circular hollow column 10. Therefore, when the movable arm 30 is in the folded position, the top end 11 of the hollow column 10 can be accommodated in the receiving groove 302 to prevent the movable arm 30 and the hollow column 10 from interfering with or colliding with each other.

[0078] like Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, a positioning hole 121 is further defined on the bottom plate 122 of the bottom end 12 of the hollow column 10. The positioning hole 121 extends through the bottom plate 122. When the movable arm 30 is in the extended position, the movable member 15 covers the positioning hole 121. When the movable arm 30 is in the retracted position, the movable member 15 does not cover the positioning hole 121. Thus, when the movable arm 30 is in the retracted position and locked, a stopper (e.g., a latch) can be inserted from the outside into the positioning hole 121 to stop the movable member 15, allowing the movable member 15 to continuously press against the elastic member 14 and prevent the movable member 15 from being moved under force, thereby allowing the movable arm 30 to remain in the locked state.

[0079] Continuing from the above, when the user needs to adjust the angle or position of the display 100 through the movable arm 30, the stopper can be disengaged from the positioning hole 121. At this time, the elastic force accumulated in the elastic member 14 can push the movable member 15 to drive the connecting member 25 to move in the direction away from the hollow column 10, so that the connecting member 25 pushes the top portion 321 of the pivot member 32 and drives the movable arm 30 to rotate relative to the hollow connecting arm 21. At the same time, the connecting member 25 can drive the positioning member 26 to move and disengage from the buckle groove 301 of the movable arm 30, so that the movable arm 30 can rotate from the folded position to the extended position and be in a freely rotatable state.

[0080] like Figure 4 and Figure 9 As shown, in this embodiment, the base 40 is provided with a positioning column 401. When the movable arm 30 is in the retracted position and locked and the bottom end 12 of the hollow column 10 is assembled on the base 40, the positioning column 401 can penetrate the positioning hole 121 of the bottom plate 122 and block the movable part 15, preventing the movable part 15 from being forced to move and allowing the movable arm 30 to continue to maintain the locked state.

[0081] like Figure 2 and Figure 3 As shown, the hollow column 10 includes a vertical slide 16, which is arranged along the extension direction of the hollow column 10. In this embodiment, one end of the vertical slide 16 is adjacent to the top end 11, and the other end of the vertical slide 16 extends toward the bottom end 12. The hollow connecting arm 21 is slidably assembled within the vertical slide 16 at a first end 22, allowing the connecting assembly 20 to slide and rise along the vertical slide 16 to change the height position of the display 100. In addition, the connecting assembly 20 can drive the movable arm 30 to move in conjunction with the hinge 32 to adjust the tilt angle and position of the display 100.

[0082] For example Figure 9 As shown, at least one constant force spring 17 can be disposed within the accommodation space 13 of the hollow column 10. One end of the constant force spring 17 is connected to the hollow column 10, and the other end of the constant force spring 17 can be directly or indirectly connected to the connecting assembly 20. In this embodiment, the constant force spring 17 is in a curled shape. When the display 100 is raised and lowered and slid along the vertical slide 16 via the connecting assembly 20, one end of the constant force spring 17 can be subjected to force and stretched. In addition, the constant force spring 17 can provide a constant elastic force, and the magnitude of the elastic force is balanced with the total weight of the movable objects such as the display 100, the connecting assembly 20, and the movable arm 30. This allows the display 100 to be positioned consistently by the elastic force of the constant force spring 17 when adjusted to different positions.

[0083] Although the technical contents of the present invention have been disclosed above in the form of preferred embodiments, they are not intended to limit the present invention. Any slight changes and modifications made by those skilled in the art without departing from the spirit of the present invention should be included in the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
