Description

Support frame and display using the same

The present invention relates to a support frame and a display using the same, and more particularly to a support frame that can change the position of the center of gravity and a display using the same.

Traditional displays include a screen and a support frame. The screen is pivotally connected to the support frame, and the pivotal connection between the screen and the support frame is mostly located on the back of the screen. Since the center of gravity of the screen is mostly adjacent to the back side, the center of gravity of the display is located between the pivot of the screen and the support frame and the back of the screen.

Because of this, when you want to adjust the viewing angle of the screen (for example, to increase the elevation angle of the screen), in order to avoid the display from falling over, you need to fix the support frame with one hand and adjust the angle of the screen with one hand. As a result, the user is inconvenienced and troubled in adjusting the viewing angle of the screen.

The invention relates to a support frame and a display using the same, which can adjust the viewing angle of the screen without fixing the support frame, and provide a simple adjustment mode for the user.

According to an embodiment of the invention, a support frame is proposed. The support frame includes a support column, a base and a center of gravity adjustment mechanism. The base is attached to the support column. The center of gravity adjustment mechanism is disposed on the base, and includes a weight, an elastic component and a lever. The elastic element is connected to the base and the weight. The lever is slidably disposed on the base. The weight is converted between a first position and a second position by the elastic element and the lever.

According to another embodiment of the invention, a display is presented. The display includes a support frame and a screen. The support frame includes a support column, a base and a center of gravity adjustment mechanism. The base is attached to the support column. The center of gravity adjustment mechanism is disposed on the base, and includes a weight, an elastic component and a lever. The elastic element is connected to the base and the weight. The lever is slidably disposed on the base. The weight is converted between a first position and a second position by the elastic element and the lever. The screen is pivoted to the support column.

In order to provide a better understanding of the above and other aspects of the present invention, the following detailed description of the embodiments and the accompanying drawings

1 and 2, FIG. 1 is an exploded view of the display according to an embodiment of the present invention, and FIG. 2 is a bottom view of the display of the first embodiment. The display 100 includes a support frame 110 and a screen 120. The screen 120 is pivotally connected to the support frame 110. The support frame 110 includes a support column 111, a base 112, and a center of gravity adjustment mechanism 113. The base 112 is coupled to the support column 111. The center of gravity adjustment mechanism 113 is disposed in the base 112 and includes at least one weight 1131, at least one elastic element 1132, and a lever 1133.

Although not shown in FIG. 2, the support frame 110 further includes a bottom cover 140 (shown in FIG. 4) that covers the bottom surface 112b of the base 112 to avoid the center of gravity adjustment mechanism 113 and the base 112 disposed in the base 112. Get rid of.

As shown in FIG. 2, the base 112 includes a first leg 1121 and a second leg 1122. The first leg 1121 is coupled to the second leg 1122 at an angle A1. The angle A1 may be an acute angle such that the base 112 is V-shaped. In this embodiment, the center of gravity adjustment mechanism 113 includes two sets of weights 1131 and elastic elements 1132. Each set of weights 1131 and elastic elements 1132 are disposed in the first leg 1121 or the second leg 1122.

The elastic member 1132 is coupled to the base 112 and the weight 1131. The lever 1133 is slidably disposed on the base 112. The weight 1131 can be changed between the first position P1 and the second position P2 by the elastic element 1132 and the lever 1133.

Referring to FIG. 3 , which is a front view of FIG. 2 , the center of gravity G of the screen 120 is generally located on one side of the pivoting portion 130 of the screen 120 and the support post 111 , such as the opposite side of the display side 121 of the screen 120 . In this case, if there is no center of gravity adjustment mechanism 113, when the viewing angle of the screen 120 is adjusted, if the support frame 110 is not separately fixed, the display 100 is usually tilted and the adjustment of the viewing angle cannot be completed. In contrast, in the embodiment, the center of gravity G of the screen 120 and the weight 1131 are located on opposite sides of the pivoting portion 130 of the screen 120 and the support post 111, so that even during the adjustment of the viewing angle of the screen 120, even if the support is not fixed The shelf 110 also prevents the display 100 from tipping over. In other embodiments, the center of gravity G of the screen 120 may also be located on the display side 121 of the screen 120, and the weight 1131 is located on the opposite side of the display side 121 of the screen 120. The viewing angle here indicates the elevation angle and the depression angle of the screen 120, and the screen 120 can be rotated around the pivoting portion 130 to adjust the viewing angle thereof.

In detail, the position of the center of gravity of the display 100 can be changed by shifting between the first position P1 and the second position P2 through the weight 1131. In this way, in the process of adjusting the viewing angle of the screen 120, even if the support frame 110 is not fixed, the display 100 can be prevented from being tilted, thereby smoothly completing the adjustment of the viewing angle. That is to say, the user can complete the adjustment of the viewing angle of the screen 120 with one hand, which is quite convenient and fast. In particular, the injured or disabled person in the opponent has considerable convenience in using the display.

Please refer to Fig. 4, which is a cross-sectional view showing a portion 4' in Fig. 3. The base 112 has a sliding groove 1123, a groove top surface 112t, and a bottom surface 112b. The sliding groove 1123 extends from the groove top surface 112t to the bottom surface 112b. When the base 112 is placed on the bearing surface S1, the weight 1131 is pressed between the groove top surface 112t and the upper surface 140u of the bottom cover 140. In one embodiment, the outer diameter of the weight 1131 is less than or substantially equal to the spacing between the top surface 112t of the groove and the upper surface 140u of the bottom cover 140, reducing the resistance or frictional force of the weight 1131. Further, the bearing surface S1 is, for example, a table top.

As shown in FIG. 4, the distance from the first position P1 to the support column 111 is shorter than the distance from the second position P2 to the support column 111. The lever 1133 is fixed to the weight 1131. For example, the lever 1133 is fixed to the weight 1131 with its end 1133d. During the process of the weight 1131 from the second position P2 to the first position P1, the elastic member 1132 is deformed to store the elastic potential energy. As such, when the weight 1131 is in the first position P1, the elastic element 1132 stores elastic potential energy.

The base 112 further includes a stop rib 1125 that can stop the shift lever 1133 to prevent the lever 1133 from being driven by the elastic member 1132 (which stores the elastic potential energy) to the second position P2. In this embodiment, the stop rib 1125 is exemplified by the first limiting portion 1133a of the stop lever 1133.

As shown in FIG. 4, the display 100 further includes a resilient member 150 that can be disposed on the base 112 or the bottom cover 140. When the lever 1133 is moved from the first position P1 to the second position P2, the lever 1133 can be displaced downward or tilted forward to disengage the stop of the stop rib 1125. When the lever 1133 is disengaged from the stop of the stop rib 1125, the elastic position of the elastic member 1132 will drive the weight 1131 from the first position P1 to the second position P2. The elastic member 150 is, for example, a spring piece, a spring or a combination of a spring piece and a spring. The aforementioned "the lever 1133 can be tilted forward" means that the first limiting portion 1133a of the lever 1133 is inclined downward, and the second limiting portion 1133b of the lever 1133 is inclined upward, so that the first lever 1133 is A limit portion 1133a can be disengaged from the stop of the stop rib 1125.

Further, when the elastic member 150 is a spring piece, the free end of the elastic member 150 faces the direction of the second position P2. Since the free end of the elastic member 150 faces the second position P2, when the first limiting portion 1133a is inclined downward, the free end of the elastic member 150 can be deformed so that the first limiting portion 1133a can be tilted downward.

Please refer to FIG. 5, which is a schematic diagram showing that the viewing angle of the screen of FIG. 4 is adjusted. When the user adjusts the viewing angle of the screen 120, as described in the above paragraph, the push lever 1133 is disengaged from the stop of the stop rib 1125. The elastic position of the elastic member 1132 will drive the weight 1131 from the first position P1 to the second position P2. In the process of moving the weight 1131 to the second position P2, the farther the distance from the weight 1131 to the support column 111 is, the longer the force arm of the weight 1131 to the pivot 130 is, so that the longer the arm The display 100 does not fall over.

Since the lever 1133 is fixed to the weight 1131, when the weight 1131 moves from the first position P1 to the second position P2, the lever 1133 is interlocked with the weight 1131.

When the weight 1131 is in the second position P2, the elastic member 1132 can be in a free state, which is not intended to limit the invention. In one embodiment, the first limiting portion 1133a of the elastic member 1132 is stopped by the limiting groove wall 114s1 or the second limiting portion 1133b is stopped by the side wall 1124 to retain some amount of stretching.

When the weight 1131 is located at the second position P2, the weight 1131 can be moved from the second position P2 to the first position P1 by pulling the lever 1133.

The lever 1133 and the weight 1131 may be combined with two separate components by a fastening technique such as locking or bonding; or the lever 1133 and the weight 1131 may be integrally formed. However, the weight of the weight 1131 can be determined by the weight and/or size of the screen 120. As long as the viewing angle of the screen 120 is adjusted, the weight of the weight 1131 can prevent the screen 120 from falling over. The weight of the weight 1131 is not limited.

As shown in FIG. 4, the base 112 has a limiting slot 114. The first limiting portion 1133a of the lever 1133 is slidably disposed in the limiting slot 114. Since the first limiting portion 1133a is restrained in the limiting slot 114, the lever 1133 can be prevented from being disengaged from the support post 111.

The base 112 further has a limiting slot wall 114s1 and 114s2 corresponding to the limiting slot 114, and the limiting slot wall 114s1 and the 114s2 are facing each other. The distance between the limiting slot walls 114s1 and 114s2 can define the position of the weight 1131. For example, when the first limiting portion 1133a is stopped by the limiting slot wall 114s1, the weight 1131 is located at the second position P2; When the limiting portion 1133a is stopped by the limiting groove wall 114s2, the weight 1131 is located at the first position P1.

The base 112 includes a side wall 1124 between the first limiting portion 1133a of the lever 1133 and the second limiting portion 1133b of the lever 1133. In an embodiment, the distance between the first limiting portion 1133a and the second limiting portion 1133b can define the position of the weight 1131. For example, when the first limiting portion 1133a is blocked by the sidewall 1124, the weight 1131 Located at the first position P1; when the second limiting portion 1133b is blocked by the side wall 1124, the weight 1131 is located at the second position P2.

Please refer to Figures 4 and 6 at the same time. Figure 6 shows an enlarged view of the lever of Figure 1. The first limiting portion 1133a includes a first shock absorbing pad 1133c, and the first limiting portion 1133a contacts the limiting groove walls 114s1 and 114s2 with the first shock absorbing pad 1133c. In this embodiment, the first limiting portion 1133a includes two first shock absorbing pads 1133c, which are opposite sides of the first limiting portion 1133a, so as to prevent the lever 1133 from colliding with the limiting slot walls 114s1 and 114s2. Intense noise. In an embodiment, the first shock absorbing pad 1133c may also be disposed on the base 112. In another embodiment, the second limiting portion 1133b may also include a first shock absorbing pad 1133c.

In the above embodiment, the elastic element 1132 is illustrated by the fact that the elastic element 1132 is stored in the first position P1. However, in another embodiment, the elastic element 1132 may also be located in the second position of the weight 1131. The elastic potential energy is stored at P2. The following is an example of Figure 7.

Please refer to FIG. 7, which is a partial cross-sectional view showing a support frame according to another embodiment of the present invention. The distance from the first position P1 to the support column 111 is shorter than the distance from the second position P2 to the support column 111. Compared with the second position P2, the weight 1131 is located at the first position P1 to obtain a longer force arm, so that when the viewing angle of the screen 120 (not shown in FIG. 7) is adjusted, the display 100 (not shown) Figure 7) does not dump.

Further, during the process of the weight 1131 from the first position P1 to the second position P2, the elastic member 1132 is deformed to store the elastic potential energy. Further, when the weight 1131 is located at the second position P2, the elastic member 1132 stores elastic potential energy.

When the weight 1131 is in the second position P2, the first limiting portion 1133a of the lever 1133 can be stopped by the stopping rib 2125 (as shown in FIG. 7), and the elastic element 1132 is prevented from releasing the elastic potential energy. The weight 1131 is brought to the first position P1.

When the lever 1133 moves from the second position P2 to the first position P1 and disengages from the stop of the stop rib 2125, the elastic member 1132 releases the elastic potential energy to drive the weight 1131 from the second position P2 to the first position. Position P1 moves.

In this embodiment, the lever 1133 may not be fixed to the weight 1131, but may be fixed to the weight 1131. When the weight 1131 moves from the second position P2 to the first position P1, even if the lever 1133 is not fixed to the weight 1131, the lever 1133 can be moved by the pushing of the weight 1131. When the weight 1131 is at the first position P1, the weight 1131 can be moved from the first position P1 to the second position P2 by pushing the lever 1133.

Further, when the weight 1131 is located at the first position P1, the elastic member 1132 can be in a free state, which is not intended to limit the present invention. In one embodiment, the resilient element 1132 can retain some amount of stretch if the first stop 1133a is stopped by the limit slot wall 114s2.

The lever 1133 may include a second shock absorbing pad 1133e, and the lever 1133 contacts the weight 1131 with the second shock absorbing pad 1133e. The second shock absorbing pad 1133e is, for example, an end portion of the lever 1133. In an embodiment, the second shock absorbing pad 1133e may also be disposed on the weight 1131.

The support frame and the display using the same according to the above embodiments of the present invention can adjust the viewing angle of the screen without fixing the support frame, and provide a simple adjustment mode for the user.

In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention.
