The disclosure will become more fully understood from the detailed description given herein below for illustration only, and thus not limitative of the disclosure, wherein:.

Please refer to <FIG>. A display apparatus D according to an exemplary embodiment of the instant disclosure is illustrated. The display apparatus D comprises a display stand holder <NUM> and a display <NUM>. In some embodiments, the display <NUM> may be a plasma display, a liquid-crystal display, a light-emitting-diode display, or other flat panel displays.

As shown in <FIG>, the display stand holder <NUM> comprises a stand body <NUM>, a pivot member <NUM>, a display assembly module <NUM>, and at least one constant-force spring <NUM>.

As shown in <FIG>, the stand body <NUM> is of an elongated bar shape and has a top end <NUM> and a bottom end <NUM>. The bottom end <NUM> is adapted to be fixed to an object, and the object may be, for example, a desk, a wall, or a floor. The top end <NUM> and the bottom end <NUM> are two opposite ends of the stand body <NUM>. In some embodiments, the stand body <NUM> is a standing-type fixing component (as shown in <FIG> and <FIG>) or an inclined-type fixing component.

As shown in <FIG>. The pivot member <NUM> may be a block, a plate, a bar, a rod, or the like and has a certain length. The pivot member <NUM> has a first end <NUM> and a second end <NUM>. The first end <NUM> is provided with a pivot portion <NUM>. The pivot portion <NUM> may be a pivot shaft or a pivot hole and is pivotally connected to the top end <NUM> of the stand body <NUM>. Therefore, when the pivot member <NUM> is subjected to a force, the pivot member <NUM> swings about the pivot portion <NUM> with respect to the top end <NUM> of the stand body <NUM>. Moreover, the second end <NUM> of the pivot member <NUM> is farer from the top end <NUM> as compared to the first end <NUM> of the pivot member <NUM> (in other words, in this embodiment, the distance between the second end <NUM> and the top end <NUM> is greater than the distance between the first end <NUM> and the top end <NUM>). Therefore, the second end <NUM> is spaced from the top end <NUM>. The distance between the second end <NUM> and the top end <NUM> is determined according to the length of the pivot member <NUM>. In other words, in this embodiment, the longer the pivot member <NUM> is, the greater the distance between the second end <NUM> and the top end <NUM> is.

As shown in <FIG>, the display assembly module <NUM> is disposed at the second end <NUM> of the pivot member <NUM> for assembling with the display <NUM>. For example, in this embodiment, the display <NUM> has a front surface <NUM> and a rear surface <NUM>, the rear surface <NUM> is provided with an assembly groove <NUM>, and the display assembly module <NUM> is assembled in the assembly groove <NUM>. Therefore, after the display <NUM> is assembled with the display assembly module <NUM>, the appearance of the assembled product can be more flat and beautiful.

In some embodiments, the display <NUM> and the display assembly module <NUM> may be assembled and fixed with each other through magnetic attracting or buckling manners. Therefore, the display <NUM> and the display assembly module <NUM> can be assembled with and disassembled from each other quickly, but embodiments are not limited thereto. In some embodiments, the display <NUM> and the display assembly module <NUM> may be assembled and fixed with each other through locking or interference fitting manners. For example, as shown in <FIG>, in this embodiment, the display assembly module <NUM> comprises a display assembly plate <NUM>. A plurality of hooks <NUM> is disposed on the display assembly plate <NUM>, a plurality of buckle holes <NUM> is in the assembly groove <NUM> of the display <NUM>, and the hooks <NUM> of the display assembly plate <NUM> are correspondingly buckled with the buckle holes <NUM> of the assembly groove <NUM> of the display <NUM>. Therefore, the display assembly module <NUM> can be assembled in the assembly groove <NUM> quickly, and the display <NUM> can be detached from the display assembly module <NUM> quickly if necessary.

As shown in <FIG>, the display assembly module <NUM> comprises a slide rail assembly <NUM>. The slide rail assembly <NUM> comprises a guide member <NUM> and a slide member <NUM>. The slide member <NUM> is slidably assembled on the guide member <NUM>, so that the slide member <NUM> is slidable with respect to the guide member <NUM>. In this embodiment, the guide member <NUM> is fixed at the second end <NUM> of the pivot member <NUM>, and the slide member <NUM> is connected to the display assembly plate <NUM>, so that the display assembly plate <NUM> and the slide member <NUM> are slidable together with respect to the guide member <NUM>. Therefore, after the display <NUM> is assembled with the display assembly plate <NUM>, the display <NUM> is capable of being slid with respect to the guide member <NUM> and the stand body <NUM> through the slide member <NUM>, so that the position of the display <NUM> can be adjusted to meet different user requirements.

As shown in <FIG>, the constant-force spring <NUM> is connected between the guide member <NUM> and the slide member <NUM>. In this embodiment, the constant-force spring <NUM> is curled. Moreover, when the display <NUM> slides with respect to the guide member <NUM> and the stand body <NUM> through the slide member <NUM>, one end of the constant-force spring <NUM> is subjected to a force, so that the constant-force spring <NUM> is pulled to be flat. Furthermore, the constant-force spring <NUM> can provide an elastic force constantly, and the value of the elastic force is balanced with the total weight of the display <NUM>, the display assembly plate <NUM>, the slide member <NUM>, and other movable components (if any). Therefore, when the display <NUM> is adjusted to different positions, the display <NUM> can be positioned through the elastic force of the constant-force spring <NUM>.

Please refer to <FIG> and <FIG>. In this embodiment, the sliding direction of the slide member <NUM> of the slide rail assembly <NUM> with respect to the guide member <NUM> (as the arrow L1 shown in <FIG>) is the same as the extension direction of the stand body <NUM>. Therefore, when the user has to adjust the height of the display <NUM>, the user can hold the display <NUM> to move with respect to the guide member <NUM> and the stand body <NUM> through the slide member <NUM> so as to change the height of the display <NUM>. When the display <NUM> is adjusted to a desired height, the user can stop forcing the display <NUM>, so that the display <NUM> can be positioned at the desired height through the elastic force of the constant-force spring <NUM>.

In some embodiments, the slide member <NUM> and the guide member <NUM> of the slide rail assembly <NUM> may be implemented by using various linear slide structures, such that the slide member <NUM> is slidable with respect to the guide member <NUM>. As shown in <FIG>, for example, in this embodiment, the slide member <NUM> is a plate member, and a surface <NUM> of the slide member <NUM> facing the stand body <NUM> has a plurality of slide grooves <NUM>, <NUM>, and the extension direction of the slide grooves <NUM>, <NUM> is the same as the extension direction of the stand body <NUM>. The slide groove <NUM> is at a middle portion of the surface <NUM>, and the slide grooves <NUM> are arranged at two opposite sides of the slide groove <NUM>. The guide member <NUM> of the slide rail assembly <NUM> is a plate member, and a surface <NUM> of the guide member <NUM> facing the slide member <NUM> comprises a guide plate <NUM> and a plurality of guide blocks <NUM>. The guide plate <NUM> is received in the slide groove <NUM>, and the guide blocks <NUM> are received in the slide grooves <NUM>. Therefore, the slide member <NUM> is slidable with respect to the guide member <NUM> stably.

As shown in <FIG>, in this embodiment, a plurality of balls <NUM> is in the slide groove <NUM> of the slide member <NUM>. The balls <NUM> are arranged at the opposite two sides of the slide groove <NUM>, and the balls <NUM> rollably contact the guide plate <NUM>. Therefore, during the process that the slide member <NUM> slides with respect to the guide member <NUM>, the friction between the guide plate <NUM> and the slide groove <NUM> can be greatly reduced, so that the slide member <NUM> can slide with respect to the guide member <NUM> more smoothly.

Further, as shown in <FIG>, in this embodiment, each of the guide blocks <NUM> of the guide member <NUM> further has a recess <NUM>, and each of the recesses <NUM> receives a constant-force spring <NUM>. Therefore, the constant-force spring <NUM> can be limited properly. Hence, during the process that the slide member <NUM> slides with respect to the guide member <NUM>, the constant-force spring <NUM> can be prevented from having deflection or wobbling.

As shown in <FIG> and <FIG>, in this embodiment, since the slide rail assembly <NUM> of the display assembly module <NUM> is assembled at the second end <NUM> of the pivot member <NUM> away from the stand body <NUM>, the display <NUM> can be kept spaced from the stand body <NUM> by a certain distance, thereby increasing the adjustable angular range of the display <NUM>. Moreover, since the slide rail assembly <NUM> is not disposed on the stand body <NUM>, the structure of the stand body <NUM> can be simplified and the appearance of the stand body <NUM> is not limited.

As shown in <FIG>, in this embodiment, the axial direction of the pivot portion <NUM> of the pivot member <NUM> is perpendicular to the extension direction of the stand body <NUM>. Therefore, after the display <NUM> is assembled with the display assembly module <NUM>, the display <NUM> is capable of swinging about the pivot portion <NUM> upwardly or downwardly with respect to the top end <NUM> of the stand body <NUM> (as the arrow L2 shown in <FIG>), so that the pitch angle of the display <NUM> (to swing upwardly or downwardly) can be adjusted. Moreover, since the display <NUM> is kept spaced from the stand body <NUM> by a certain distance, the adjustable range of the pitch angle of the display <NUM> is further increased. Furthermore, since the pivot member <NUM> is pivotally connected to the top end <NUM> of the stand body <NUM>, the angle to swing the display <NUM> upwardly is not limited, thereby further increasing the adjustable range of the elevation angle of the display <NUM>.

As shown in <FIG> and <FIG>, in this embodiment, the pivot member <NUM> is further provided with a rotation shaft <NUM> between the first end <NUM> and the second end <NUM>, and the axial direction of the rotation shaft <NUM> is perpendicular to the axial direction of the pivot portion <NUM>. Therefore, after the display <NUM> is assembled with the display assembly module <NUM>, the display <NUM> is capable of being rotated about the rotation shaft <NUM> leftward or rightward with respect to the stand body <NUM> (as the arrow L3 shown in <FIG>), so that the lateral tilt angle of the display <NUM> can be adjusted. Moreover, since the display <NUM> is kept spaced from the stand body <NUM> by a certain distance, the adjustable range of the lateral tilt angle of the display <NUM> can be further increased.

As shown in <FIG>, <FIG>, and <FIG>, the display assembly plate <NUM> is further rotatably assembled on the slide rail assembly <NUM>. Therefore, after the display <NUM> is assembled with the display assembly plate <NUM>, the display <NUM> not only can be moved upwardly or downwardly for adjusting the height of the display <NUM> and can be rotated for adjusting the pitch angle and the lateral tilt angle, the display <NUM> but also can be rotated with respect to the slide rail assembly <NUM> and the stand body <NUM> (as the arrow L4 shown in <FIG>), so that the display <NUM> can be adjusted to different rotation angles.

Further, as shown in <FIG>, <FIG>, and <FIG>, in this embodiment, the display assembly plate <NUM> has an axial through hole <NUM>, a damper plate <NUM> is fixedly disposed in the axial through hole <NUM>, and the damper plate <NUM> contacts the display assembly plate <NUM>. Therefore, when the display <NUM> is rotated to a different position through the display assembly plate <NUM> with respect to the slide rail assembly <NUM> and the stand body <NUM>, the display <NUM> can be positioned through the friction between the damper plate <NUM> and the display assembly plate <NUM>. Moreover, the display assembly plate <NUM> may further comprise a ring-shaped damper sheet <NUM>, the ring-shaped damper sheet <NUM> is disposed around a hole edge of the axial through hole <NUM>, and the ring-shaped damper sheet <NUM> contacts the damper plate <NUM>. Therefore, the friction between the display assembly plate <NUM> and the damper plate <NUM> can be increased to enhance the positioning performance for the display <NUM>.

In some embodiments, the ring-shaped damper sheet <NUM> and the damper plate <NUM> may be made of polymer resin material or rubber material, thereby further reducing the noises and shakings of the display assembly plate <NUM> during the rotation of the display assembly plate <NUM> and increasing the service lives of the ring-shaped damper sheet <NUM> and the damper plate <NUM>.

As shown in <FIG> and <FIG>, the display assembly module <NUM> comprises a ring-shaped frame <NUM>. The ring-shaped frame <NUM> is connected to a periphery of the display assembly plate <NUM> and extends toward the stand body <NUM>. The ring-shaped frame <NUM> has an inner peripheral portion <NUM>, the inner peripheral portion <NUM> is enclosed to form a receiving groove <NUM>, and the slide rail assembly <NUM> is received in the receiving groove <NUM>. Moreover, one side of the receiving groove <NUM> adjacent to the pivot member <NUM> is further provided with a cover plate <NUM>. Therefore, the slide rail assembly <NUM> can be hidden in the receiving groove <NUM> to improve the aesthetics of the entire display assembly module <NUM>.

Further, as shown in <FIG> and <FIG>, the cover plate <NUM> has an elongated guide slot <NUM> in communication with the receiving groove <NUM>. The extension direction of the elongated guide slot <NUM> is the same as the slide direction of the slide member <NUM> (as the arrow L1 shown in <FIG>). The second end <NUM> of the pivot member <NUM> is inserted into the elongated guide slot <NUM> so as to be connected to the guide member <NUM> of the slide rail assembly <NUM>. Therefore, when the display <NUM> is subjected to a force, the force drives the slide member <NUM>, the display assembly plate <NUM>, the ring-shaped frame <NUM>, and the cover plate <NUM> to slide with respect to the guide member <NUM>. Moreover, through the configuration of the elongated guide slot <NUM>, the cover plate <NUM> can be prevented from interfered with or impacting the pivot member <NUM> during the sliding of the components.

Please refer to <FIG> and <FIG>, at least one elastic member <NUM> (in this embodiment, the number of the elastic members <NUM> is two, but embodiments are not limited thereto) is further connected between the first end <NUM> of the pivot member <NUM> and the stand body <NUM>. Therefore, after the display <NUM> swings through the pivot member <NUM> with respect to the stand body <NUM> to adjust the angle of the display <NUM>, the display <NUM> can be positioned through the elastic force provided by the elastic member <NUM>. In this embodiment, the elastic member <NUM> is an extension spring. One of two ends of the elastic member <NUM> is connected to the first end <NUM> of the pivot member <NUM>, and the other end of the elastic member <NUM> is connected to the stand body <NUM>.

In some embodiments, the elastic member <NUM> may be other elastic components, such as a torsion spring or a leaf spring.

As shown in <FIG> and <FIG>, in this embodiment, a movable plate <NUM> is disposed in the stand body <NUM>. The movable plate <NUM> is movable with respect to the stand body <NUM> to adjust the position of the movable plate <NUM>. The other end of the elastic member <NUM> is connected to the movable plate <NUM>. Therefore, through the movement of the movable plate <NUM>, the extension extent of the elastic member <NUM> can be adjusted, thereby changing the elastic force of the elastic member <NUM> according to actual requirements.

Further, as shown in <FIG>, a transmission element <NUM> is disposed in the stand body <NUM>. In this embodiment, the transmission component <NUM> is an elongated bolt, and one end of the transmission element <NUM> is threaded with the movable plate <NUM>. Therefore, the user can operate the transmission element <NUM> to rotate so as to drive the movable plate <NUM> to move with respect to the stand body <NUM>, thereby changing the elastic force of the elastic member <NUM>. However, it is understood that the foregoing embodiments are provided for illustrative purposes, but not limitations of the instant disclosure. In some embodiments, the transmission element <NUM> may be other transmission structures (such as a chain transmission structure or a gear transmission structure).

In some embodiments, the bottom end <NUM> of the stand body <NUM> is further assembled on a base <NUM>, and the base <NUM> is adapted to be fixed on a desk plate <NUM> or a desk clip <NUM>. As shown in <FIG> and <FIG>, for example, the base <NUM> may be directly fixed on a desk plate <NUM>, so that the stand body <NUM> can be fixed at a predetermined angle. For example, the angle between the stand body <NUM> and the desk plate <NUM> may be <NUM> degrees, <NUM> degrees, <NUM> degrees, or <NUM> degrees. Alternatively, as shown in <FIG>, the base <NUM> may be fixed on a desk clip <NUM>. The desk clip <NUM> can be clipped at the edge of the desk, so that the user can choose the position where the stand body <NUM> is located on the desk.

As shown in <FIG> and <FIG>, the bottom end <NUM> of the stand body <NUM> is pivotally connected to the base <NUM>, so that the stand body <NUM> is swingable with respect to the base <NUM> to adjust the tilt angle of the stand body <NUM>, thereby further adjusting the position of the display <NUM>. Moreover, at least one elastic member <NUM> is connected between the base <NUM> and the stand body <NUM> (in this embodiment, the number of the elastic members <NUM> is three, but embodiments are not limited thereto). Therefore, after the stand body <NUM> swings with respect to the base <NUM> to adjust the tilt angle of the stand body <NUM>, the stand body <NUM> can be positioned through the elastic force provided by the elastic member <NUM>. In this embodiment, the elastic member <NUM> is an extension spring. One of two ends of the elastic member <NUM> is connected to the bottom end <NUM> of the stand body <NUM>, and the other end of the elastic member <NUM> is connected to the base <NUM>.

Further, as shown in <FIG> and <FIG>, in this embodiment, a movable plate <NUM> is disposed in the stand body <NUM>. The movable plate <NUM> is movable with respect to the stand body <NUM> to adjust the position of the movable plate <NUM>. The end of the elastic member <NUM> connected to the stand body <NUM> is connected to the movable plate <NUM>. Therefore, through the movement of the movable plate <NUM>, the extension extent of the elastic member <NUM> can be adjusted, thereby changing the elastic force of the elastic member <NUM> according to actual requirements.

Moreover, please refer to <FIG> and <FIG>. The display stand holder <NUM> further comprises at least one multi-link assembly <NUM>. In this embodiment, the number of the multi-link assemblies <NUM> is two, and the two multi-link assemblies <NUM> are connected to two opposite sides of the stand body <NUM>. The multi-link assembly <NUM> is adapted to allow the display <NUM> to be retained at the original viewing angle to prevent the display <NUM> and the pivot member <NUM> from swinging along with the swinging of the stand body <NUM> during the process that the stand body <NUM> swings with respect to the base <NUM> to adjust the tilt angle of the stand body <NUM>. The detail operation of the multi-link assembly <NUM> is provided as below.

As shown in <FIG> and <FIG>, taking one of the multi-link assembly <NUM> as an example, the multi-link assembly <NUM> comprises a first connecting rod <NUM>, a second connecting rod <NUM>, a third connecting rod <NUM>, and a fourth connecting rod <NUM>. The first connecting rod <NUM> is connected to the pivot portion <NUM> of the pivot member <NUM>, and the top end <NUM> of the stand body <NUM> is sandwiched between the first connecting rod <NUM> and the pivot portion <NUM>, so that the top end <NUM> of the stand body <NUM> is still rotatable with respect to the first connecting rod <NUM> and the pivot portion <NUM>. The second connecting rod <NUM> is connected to the base <NUM>, and the bottom end <NUM> of the stand body <NUM> is sandwiched between the second connecting rod <NUM> and the base <NUM>, so that the bottom end <NUM> of the stand body <NUM> is still rotatable with respect to the second connecting rod <NUM> and the base <NUM>. The third connecting rod <NUM> and the fourth connecting rod <NUM> of the multi-link assembly <NUM> are parallel with each other. Two ends of the third connecting rod <NUM> are pivotally connected to the first connecting rod <NUM> and the second connecting rod <NUM>, and two ends of the fourth connecting rod <NUM> are pivotally connected to the first connecting rod <NUM> and the second connecting rod <NUM>. Therefore, in this embodiment, the multi-link assembly <NUM> is formed as a parallel four connecting rod structure.

Therefore, as shown in <FIG> and <FIG>, when the user operates the stand body <NUM> to swing with respect to the base <NUM> to adjust the tilt angle of the stand body <NUM>, the top end <NUM> of the stand body <NUM> is rotatable with respect to the pivot member <NUM>, and the bottom end <NUM> of the stand body <NUM> is rotatable with respect to the base <NUM>. Moreover, the third connecting rod <NUM> and the fourth connecting rod <NUM> of the multi-link assembly <NUM> are also swingable with respect to the first connecting rod <NUM> and the second connecting rod <NUM>, so that the third connecting rod <NUM> and the fourth connecting rod <NUM> swing along with the swinging of the stand body <NUM>, thereby changing the tilt angle of the stand body <NUM>. Moreover, since the pivot portion <NUM> of the pivot member <NUM> is connected to the first connecting rod <NUM>, the pivot portion <NUM> of the pivot member <NUM> can be limited by the multi-link assembly <NUM> and does not rotate with respect to the stand body <NUM>. Therefore, the display <NUM> connected to the pivot member <NUM> can be retained at the original viewing angle.

As shown in <FIG>, the display stand holder <NUM> may further comprise a plurality of bolts <NUM>. The first connecting rod <NUM> of the multi-link assembly <NUM> can be connected to the pivot portion <NUM> of the pivot member <NUM> by inserting the bolts <NUM> into the top end <NUM> of the stand body <NUM>, and the top end <NUM> of the stand body <NUM> can be sandwiched between the first connecting rod <NUM> and the pivot portion <NUM>. As shown in <FIG>, the second connecting rod <NUM> of the multi-link assembly <NUM> can be connected to the base <NUM> by inserting the bolts <NUM> into the bottom end <NUM> of the stand body <NUM>, and the bottom end <NUM> of the stand body <NUM> can be sandwiched between the second connecting rod <NUM> and the base <NUM>. However, it is understood that the assembling configuration of the multi-link assembly <NUM> is provided as an illustrative example, but not limitations of the instant disclosure.

As shown in <FIG>, in this embodiment, the display stand holder <NUM> further comprises at least one friction sheet <NUM> (in this embodiment, the number of the friction sheet <NUM> is two, but embodiments are not limited thereto). The friction sheet <NUM> contacts the first end <NUM> of the pivot member <NUM> and the top end <NUM> of the stand body <NUM>. Therefore, when the stand body <NUM> is rotated with respect to the pivot member <NUM> and the base <NUM> to a different tilt angle, the positioning of the stand body <NUM> at the angle can be enhanced through the friction among the friction sheet <NUM>, the pivot member <NUM>, and the stand body <NUM>.

Further, as shown in <FIG>, the display stand holder <NUM> further comprises an angular limit plate <NUM>. The angular limit plate <NUM> is disposed between the first end <NUM> of the pivot member <NUM> and the top end <NUM> of the stand body <NUM>. Moreover, the angular limit plate <NUM> has a limit notch <NUM>, the first end <NUM> of the pivot member <NUM> is provided with a limit block <NUM>, the limit block <NUM> is received in the limit notch <NUM>, and the width of the limit notch <NUM> is greater than the width of the limit block <NUM>. Therefore, as shown in <FIG> and <FIG>, when the stand body <NUM> is rotated with respect to the pivot member <NUM> and the base <NUM>, the rotatable angle of the stand body <NUM> can be limited through the angular limit plate <NUM> and the limit block <NUM>.
