Description

Arm linkage apparatus for display apparatus {A Display system arm linkage apparatus}

The present invention relates to an arm link device for a display device that makes it easy to see a display device in a limited space, and in particular, to allow a large range of adjustment according to the weight of the display device that is installed in a restricted space due to narrow space. Due to the heavy adjustment of the display device up and down to prevent the sag caused by weight and to control the pop-up (POP-UP) phenomenon by the high elastic member to provide convenience and ease of use.

In general, display devices such as TVs and computer monitors are used for various purposes of medical display devices or various industrial display devices as a medium for transmitting information in an image.

Therefore, the display device is mounted on the arm link device that controls the movement in various directions such as left, right, up, and down so that the user can be positioned at a comfortable position according to the use even in a narrow space. It is designed to be freely and easily adjusted while maintaining the state without changing the angle of the device.

As described above, the structure of the arm link device of the display apparatus, which is conventionally used, has a fixed bracket for fixing a support bar on which one side is mounted with a floating bracket moving to the left and right and a display bar on the other side to the arm link body. It is installed by the shaft coupling and the inner side of the arm link body is formed through the elastic shape for distributing the load of the display device in the through-hole is fitted to the link shaft and prevent the separation of the elastic member on both sides of the link shaft in which the elastic member is fitted While one side of the bushing coupled to one side to limit the movement of the link shaft to some extent is coupled, a thread is formed on one side of the link shaft is coupled to the tightening nut for adjusting the variable length of the elastic member in the thread and the arm of the portion where the tightening nut is coupled Tightening incision to adjust the link body tightening nut from the outside to the fastener Formed structure.

At this time, at both ends of the link shaft, a link connected to a floating bracket and a fixed bracket installed by shaft coupling by shaft pins on both sides of the arm link body for moving the display device up and down while maintaining the vertical state is coupled to a separate clip. And axially coupled edges of the fixing bracket, that is, they are installed so as to be eccentrically coupled respectively.

However, this is because a small load device having a small load disperses or sustains a sufficient load by the elastic member mounted on the arm link device. However, these days, the display device has been developed and enlarged and used a lot of large screens. These large display devices have a larger load as the volume increases, and when a large display device with such a load is mounted The elastic member mounted on the female link device is designed so that the variable length that can support the load by distributing the load of the display device is changed only to a certain part. Can not support The link arm device equipped with slip value will be increasingly sagging phenomenon.

Therefore, when the high elastic member having a strong compressive force is used for the elastic member to prevent the deflection of the display device, the deflection phenomenon is prevented, but due to the characteristics of the elastic member, the variable range of the display device is narrow, so that even a slight change in weight There was a problem that the pop-up (POP-UP) phenomenon to occur again in the arm link device.

In addition, because the fixed bracket and the flow bracket coupled to both sides of the arm link body is simply axially coupled by the shaft pin, there was a problem that the high-elasticity does not separately control the pop-up phenomenon caused by the return.

Therefore, conventionally, when a heavy display device is mounted, there is no device that simultaneously controls the deflection phenomenon and the pop-up phenomenon in the arm link device, causing inconvenience in use.

Therefore, the present invention has been made in order to solve the above-mentioned problems, the force required for a heavy display device by mounting a separate second elastic member to operate as a first elastic member to distribute and support the load of the display device In order to prevent sag and secured by a shaft pin to the floating bracket and the fixed bracket installed on both sides of the arm link body, the display device is hinged to a separate clip spring so that the display device returns to its original position due to the high elastic member. By limiting the pop-up (POP-UP) to go back to solve the conventional problem.

In order to achieve the above object, in the present invention, the first elastic member coupled to the link shaft inside the arm linkage device is operated by gas pressure or the like at a position parallel to the first elastic member to support and distribute the load of the display device. 2 The elastic member is installed to operate simultaneously with one connecting bracket so that the first elastic member and the second elastic member simultaneously secure the necessary force to support the load even when the heavy display device is mounted. This will prevent the device from sagging.

In addition, when axially coupling the flow bracket and the fixed bracket installed on both sides of the arm link body to the shaft pin is coupled to the shaft groove to which the shaft pin is coupled, the coupling of the shaft pin relatively larger than the diameter of the clip spring by force fitting By installing the hinge to control the force to prevent the pop-up phenomenon to return to the original position due to the high elastic member.

Therefore, as described above, the present invention increases the variable range according to the weight of the heavy display device and secures the necessary force to support it, thereby freely adjusting the height and distance of the heavy display device, and then returning it to the desired position. The pop-up phenomenon and the sag phenomenon to be prevented at the same time to provide the effect that the user can use without inconvenience.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is an exploded perspective view showing the structure of the arm link of the present invention and Figures 2 to 4 are cross-sectional view showing a state in which the arm link of the present invention operates.

As shown in FIG. 1 to FIG. 5, the arm link device of the present invention has a fixed bracket 30 to which the support bracket on which the display device is mounted is mounted on the other side and the movable bracket 40 moves to the left and right sides, respectively. The inner side is axially coupled to both sides of the through-hole female link body 10 by the shaft pin 50 and the arm link body 10 is in the form of the through-hole through the link shaft 20 to distribute and support the load of the display device The elastic member 21 is coupled to one side of the coupled elastic member 21 is supported to be coupled in a state in which the fastener 14 is mounted on the inner side so that the elastic member 21 has a compressive force and the link shaft ( Both sides of the 20 are eccentrically coupled by the link 28 to the flow bracket 40 and the fixed bracket 30 axially coupled to the arm link body 10, respectively, when the display device moves up and down the display device. This can be maintained while maintaining the vertical In the link shaft 20, the link coupling portion 20a, which is eccentrically coupled to the floating bracket 40 and the fixed bracket 30, is integrally formed on both sides of the link shaft 20 so as to have a first elasticity on one side of the link shaft 20. A screw thread 20b for adjusting the variable length of the member 21 is formed, and the first elastic member 21 coupled to the link shaft 20 prevents the arm link body 10 from being separated from the link shaft 20. One side of the bushing 24 and the bushing fixture 25 which hold the movement of the less movement is coupled to be supported by the fixture 14 mounted on the arm link body 10 and the bushing 24 and the bushing fixture 25 The second elastic member 22 is coupled to the link shaft 20 by the coupling bracket 23 so that the first elastic member 21 is coupled to the first elastic member 21 and is simultaneously symmetric with the first elastic member 21. Fastening nut 26 for adjusting the variable length of the first elastic member 21 coupled to and then coupled to the thread 20b of the link shaft 20 The captive cutout part 11 is formed on the arm link body 10 of the part to which the tightening nut 26 is coupled so as to be adjusted to the tightening nut 26, and the cover 13 is coupled to the upper side thereof. It is a structure built.

In this case, the first elastic member 21 is used as a compression spring in the form of a coil and the first elastic member 21 can be used as various elastic members without limiting the compression spring in the form of a coil.

In this case, as shown in FIGS. 5 to 7, the second elastic member 22, which is symmetrically coupled to the first elastic member 21 in order to distribute and support the load of the display device, has a gas pressure bar operated by gas pressure. It is also used and may have the same effect even if the compression spring 21 of the same coil form as the first elastic member 21 in place of the gas shock bar.

In this case, when the arm link device equipped with the heavy display device is lifted as shown in FIG. 2, the gas shock bar already supports a part of the weight of the second elastic member 22 that is rapidly rising even if the gas display bar is installed with the heavy display device. Therefore, the first elastic member 21 and the second elastic member 22 simultaneously control the remaining length of the first elastic member 21 with the tightening nut 26 to adjust the remaining value of the force necessary to support the display device. It is possible to prevent the deflection of the display device by securing a force capable of supporting a load slightly heavier than the load that can support the mounted display device by the operation of.

And when the arm link device is axially coupled to the floating bracket 40 as shown in Figure 3 when the link 28 eccentrically coupled to the fixed bracket 30 to maintain the vertical state while supporting the load of the display device The link 28 is moved so that the eccentrically coupled portion of the link is perpendicular to the axially coupled portion.

In this case, as the display device is fixed in the lowered state by the distance that the link 28 is moved, the load value becomes larger, and the first elastic member 21 and the first elastic member 21 to support the display device with the increased load do not rise again. The second elastic member 22 is operated by the connecting bracket 23 at the same time to be compressed while the display device is not lowered but is maintained vertically lowered even if the arm link device is lowered.

Therefore, this operation principle is connected to the first elastic member 21 and the bracket connected to the adjustable length of the tightening nut 26 in order to support the weight of the display device mounted even if the heavy display device is mounted on the arm link device. By the second elastic member 22 which is operated simultaneously by 23, the variable range is increased, thereby securing the necessary force for supporting the load of the display device even when the arm link device equipped with the heavy display device is moved up and down. Deflection and pop-up phenomenon will be prevented.

In addition, a display device that has a much higher weight by integrally additionally installing a separate first elastic member 21 identical to the first elastic member 21 to one side of the gas shobar used as the second elastic member 22. It becomes usable, which means that the variable range for the weight becomes much larger and can have more effect.

At this time, the connecting bracket 23 has a through groove 23a through which the link shaft 20 penetrates on the upper side and a coupling groove 23b through which the second elastic member 22 is coupled to the lower side. The first elastic member 21 coupled to the link shaft 20 is supported on one side of the connecting bracket 23 and the bushing fixture and the bushing fixture supported by the fastener and is symmetrical in the same line to the lower side of the first elastic member 21. The second elastic member 22 is also mounted so as to be supported by the connecting bracket and the fixture so that the first elastic member 21 and the second elastic member 22 are operated simultaneously by the connecting bracket 23 when the arm link device is operated. As a result, it is necessary to secure the force necessary to support the load of the display apparatus.

In this case, the first elastic member 21 coupled to the link shaft 20 coupled to the inner side of the female link body 10 is supported on one side, and the fastener 14 mounted to have a compressive force is formed in a plate plate shape. The plate-shaped fastener 14 is fitted in one direction of the inner side of the female link body 10 to be coupled by a screw or the like to facilitate the coupling.

In addition, in order to couple the plate plate used as the fixture 14, the through hole inside the arm link body 10 is first elastic member 21 and the second elastic member 22 symmetrically mounted to the link shaft 20 The plate plate used as the fastener 14 is formed in the ribs 12 to be formed and fitted with a width equal to the width of the) and is fixed by screws.

In addition, the fastener 14 is formed into a plate plate to compress the force that is compressed when the first elastic member 21 and the second elastic member 22 simultaneously operated by the connecting bracket 23 to the plate plate. By supporting the entire surface of the fixed fixture 14, it is possible to sufficiently support the compression force.

In addition, the plate shaft used as the fixture 14 to form an opening groove 15 of a predetermined size, so that the link shaft 20 to which the first elastic member 21 is coupled is connected to the display device through the opening groove 15. When the arm linkage device is mounted, the link shaft 20 passes through the link shaft 20 so that the link shaft 20 flows in the longitudinal direction.

Meanwhile, as shown in FIG. 8, the tightening nut 26 adjusts the compressive force of the first elastic member 21 by adjusting the variable length of the first elastic member 21.

In addition, between the tightening nut 26 and the connecting bracket 23 to be coupled to the washer 27 of the plastic-specific material to tighten the tightening when tightening the tightening nut 26.

In addition, when the tightening cutout portion 11 formed at one side of the arm link body 10 of the portion in which the tightening nut 26 is mounted is formed to have a predetermined width and length, when the tightening nut 26 is adjusted using the tightening hole. It is easy to use for adjustment and to facilitate the use of the adjustment of the tightening nut 26 by engaging the cover 13 so that dust or foreign matter does not enter the opening tightening incision (11). .

At this time, Figure 10 is a perspective view showing a clip spring 31 of the shaft groove coupled to the shaft pin 50 when the fixed bracket 30 and the floating bracket 40 is axially coupled to both sides of the arm link body (10). The clip spring 31 is formed in a state in which mounting grooves 32 and 42 to which the clip springs 31 having a predetermined diameter are mounted are formed on one side, and the clip springs 31 are mounted to the mounting grooves 32 and 42. The shaft pin 50 is larger than the diameter of the to be coupled by force fitting.

This is possible by the shaft pin 50 is coupled to the arm link body 10 and the fixed bracket 30 and the floating bracket 40 coupled to both sides while the mounting of the fixed bracket 30 and the floating bracket 40 The clip springs 31 coupled to the grooves 32 and 42 cause friction with the shaft pin 50, and the friction force is used to hold the pop-up secondary.

Therefore, even when the heavy display device is mounted, the first elastic member 21 and the second elastic member 21 symmetrically coupled to the first elastic member 21 installed inside the arm link body 10 while the load of the display device is mounted ( 22) is to prevent the display device from sag and the fixed bracket 30 and the floating bracket 40, which are axially coupled to both sides of the arm link device, are clipped to the hinge 31 to return to the original position. The pop-up phenomenon that tries to return again does not occur.
