Description

Display support

Technical Field

The present application relates to a display stand, and more particularly, to a display stand having a simple structure, which is mounted on a wall near a bed or a desk to improve usability by naturally adjusting an optimal distance from eyes of a user according to the position or posture of the user.

Background

With the development of mobile communication technology, portable display devices for viewing images such as mobile phones, tablet computers, notebook computers, etc. have been widely used. In order to mount such a display device so that images can be appreciated at a fixed location, the display stand will be used together.

Such an existing display bracket may be rotatably installed at one side of a bed for a user to enjoy video while lying down even when a patient with difficulty in movement or a person who wants to enjoy a predetermined image while lying down in the bed at home.

However, since the conventional display stand has a limited range of rotation adjustment in which a user can lie in the center of a bed and look forward, it is inconvenient to turn the head according to the lying position of the user in order to look at the display device from the front. Therefore, not only fatigue is felt, but also diseases such as stiff neck and herniation of cervical disc may occur.

To solve this problem, in patent No. 10-1701558 filed and registered by the present inventors, a mount is rotatably mounted on a wall so that a user can see a display stand from the front by rotating the mount sideways even if the user is lying on his/her side in a bed. In addition, the mounting frame is formed in a shape in which the bending frame to which the display device is mounted slides from the main frame, and through holes are formed in the bending frame and the main frame, and fixing pins are inserted in a state in which the respective through holes of the bending frame and the main frame are aligned, so that the bending frame is protruded from the main frame.

However, when the user lying on the front side rotates the mounting frame sideways while lying on his side, the display device becomes closer to the eyes of the user due to the radius of rotation of the mounting frame, and the user must separate the fixing pins, extend the curved frame from the main frame, and then reinsert the fixing pins, thus complicating operation, resulting in poor usability. In particular, in the case of a patient, since the hand cannot reach the display device provided at the front end of the curved frame, the above operation is not easy, and thus there is a problem in that the posture cannot be changed alone and the image cannot be viewed in a comfortable posture.

Disclosure of Invention

Technical problem to be solved

The present application has been made in view of the above-described problems, and an object of the present application is to provide a display stand that has a simple structure, maintains an optimal distance between the display and the eyes of the user even if the posture or position of the user changes, allows the user to easily adjust the display without help of other people, allows the user to view the front, and improves the convenience of use, and allows the user to view the display comfortably in a comfortable posture without causing a disease such as stiffness of the neck, thereby improving customer satisfaction.

Technical proposal

To achieve the object, the display stand of the present application is characterized by comprising: a fixed frame 10 having an inclined rotation shaft 12 mounted on the mounting wall 1 and inclined gradually downward from the front of the mounting wall 1; a rotating lever 20 forming a predetermined angle (θ) with the tilting rotation shaft 12 of the fixed frame 10, one end of which has a predetermined rotation locus around the center of the tilting rotation shaft 12 so as to be rotatably connected on the tilting rotation shaft 12, and gradually tilting upward toward the front when being positioned at the top of the rotation locus; and a slide lever 30 having one end slidably connected to the other end of the rotating lever 20 and configured to be stretched and contracted in the rotating lever 20 according to a rotation locus of the rotating lever 20, and the other end mounted with the display 2.

According to another feature of the present application, a handle 60 protruding inward with respect to the rotation locus is further provided at the slide lever 30, and the rotating lever 20 has a guide hole 24 extending in the longitudinal direction so that the handle 60 of the slide lever 30 is moved.

According to another feature of the present application, long holes 22 extending in the longitudinal direction are formed in the side surface of the rotating lever 20 or the sliding lever 30, a plurality of insertion grooves 32 are formed in the sliding lever 30 or the rotating lever 20 at intervals in the longitudinal direction, and a positioning pin 40 inserted into the insertion grooves 32 through the long holes 22 is further provided.

According to another feature of the application, the fixed frame 10 or the rotating rod 20 is further provided with a stopper 50 for limiting the rotation of the rotating rod 20.

Advantageous effects

As described above, according to the present application, the rotating lever 20 has a phase inclined in a front direction toward the installation wall 1, since the sliding lever 30 mounted with the display 2 is stretched and contracted by its own weight according to the rotation track of the rotating lever 20, since the distance between the eyes of the user U and the display 2 is automatically adjusted according to the rotation of the rotating lever 20, although the structure is simple, the user U does not need to manually stretch and retract the sliding lever 30 after rising from the lying state, improving the convenience of use. When the patient who is inconvenient in movement rotates the rotating lever 20 only by hand at the time of changing the posture, the display 2 is spaced apart from the eyes thereof by an appropriate distance, so that the user U can view the display 2 in a comfortable posture, further improving the convenience of use. On the other hand, the handle 60 is provided on the slide bar 30, and the guide hole 24 through which the handle 60 of the slide bar 30 is moved is formed on the rotating bar 20, so that the user can grasp the handle 60 and move the slide bar 30 to a desired position, and the user can take a more diverse posture while spacing the display 2 from his eyes by a more appropriate distance, thereby enabling the user to view the display 2 in a more comfortable posture, thereby further improving the convenience of use.

In addition, since each user U can adjust the distance by which the slide bar 30 is extended and contracted with respect to the rotating bar 20, since the display 2 mounted on the slide bar 30 can be freely set according to the body structure or posture of each user U, thereby providing a posture of eyes of the user U more optimized, easily adjustable to suit each person, and excellent usability and versatility. On the other hand, the fixing frame 10 or the rotating lever 20 is provided with a stopper 50 for restricting the rotation of the rotating lever 20, so that the rotating lever 20 can be prevented from being excessively rotated to collide with the installation wall 1 or the surrounding articles, thereby improving safety.

Detailed Description

The above objects, features, and advantages of the present application will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present application will be described based on the drawings.

Fig. 1 to 6 are views showing a display stand according to an embodiment of the present application. As shown in the drawings, the monitor stand according to an embodiment of the present application includes a fixed frame 10, a rotating lever 20, and a sliding lever 30.

The fixed frame 10 is provided with an inclined rotation shaft 12 which is inclined gradually downward from the front of the installation wall 1, and as shown in fig. 1 and 4, includes a fixed portion 11 fixed to the installation wall 1 and an inclined rotation shaft 12 provided at the front end of the fixed portion 11.

The rotating lever 20 forms a predetermined angle (θ) with the tilting rotation shaft 12 of the fixed frame 10, and one end thereof has a predetermined rotation locus around the center of the tilting rotation shaft 12 so as to be rotatably connected on the tilting rotation shaft 12. A rotation connection ring 21 rotatably connected to the tilt rotation shaft 12 may be provided at one end of the rotation lever 20.

As shown in fig. 4, when the rotating lever 20 is positioned at the top of the rotation locus, it is disposed to be inclined upward from one end to the other end. As shown in fig. 1 and 2, one end of the rotating rod 20 is rotatably connected to the upper end of the inclined rotating shaft 12 of the fixed frame 10, one end of the supporting rod 13 is rotatably connected to the other end of the inclined rotating shaft 12, and the other end is connected to the rotating rod 20 to more stably support the rotating rod 20. An auxiliary rotating connection ring 14 rotatably connected to the tilting rotation shaft 12 may be further provided at one end of the support bar 13.

One end of the sliding lever 30 is slidably connected to the other end of the rotating lever 20, and is configured to be automatically or manually stretched and contracted in the rotating lever 20 according to a rotation locus of the rotating lever 20. In the present embodiment, the slide lever 30 is stretched and contracted by its own weight according to the phase of the rotating lever 20. In addition, the slide bar 30 is caught at an end portion thereof to an end portion of the rotating bar 20, preventing the complete separation from being combined with the structure of the rotating bar 20, even if the slide bar 30 is stretched and contracted in the rotating bar 20 due to its own weight.

On the other hand, as shown in fig. 2, the other end of the slide lever 30 is provided with a display mounting portion 31 to which the display 2 is mounted. As is well known, the display mounting portion 31 may be configured to rotate in various directions at the end of the slide bar 30.

Also, as shown in fig. 2, the slide bar 30 is inserted into the inside of the rotating bar 20, however, the rotating bar 20 may be inserted into the slide bar 30. On the other hand, the slide bar 30 may not be bent or curved, as shown in fig. 2, and preferably the display 2 is formed in a bent or curved shape so that the display 2 can be positioned at a better distance from the eyes of the user U.

A display bracket according to an embodiment of the present application may be configured to adjust the length of extension and contraction of the slide bar 30 with respect to the rotating bar 20. By adjusting the extension length of the slide bar 30 when it is stretched by its own weight in the rotating bar 20, the display 2 mounted on the slide bar 30 can be positioned at a better distance from the eyes of the user, since the physical condition or posture of each user is different.

The monitor bracket according to the embodiment of the present application has the long hole 22 in the longitudinal direction in the rotating lever 20 or the sliding lever 30 to adjust the length of the sliding lever 30 extending in the rotating lever 20, a plurality of insertion grooves 32 spaced apart in the longitudinal direction of the sliding lever 30 or the rotating lever 20 may be provided, and the positioning pin 40 is inserted into the insertion grooves 32 through the long hole 22.

As shown in fig. 2, the rotating lever 20 is formed with a long hole 22, and the sliding lever 30 is formed with an insertion groove 32. Therefore, when the positioning pin 40 is inserted into the insertion groove 32 of either side of the slide bar 30 through the long hole 22 of the rotating bar 20, the positioning pin 40 is caught by the end inserted into the long hole 22, and the slide bar 30 adjusts the length stretched from the rotating bar 20.

That is, as shown in fig. 4, when the rotating lever 20 is positioned at the top of the rotating trace, the sliding lever 30 is inserted into the rotating lever 20 by its own weight, and the sliding lever 30 is prevented from being reinserted into the rotating lever 20 due to the positioning pin 40 being caught at one end of the long hole 22 of the rotating lever 20, thereby preventing the display 2 mounted at the other end of the sliding lever 30 from excessively approaching the eyes of the user U.

When the rotating lever 20 is rotated and is gradually inclined downward toward the other end as shown in fig. 3 and 5, the slide lever 30 is extended from the rotating lever 20 by its own weight, and the positioning pin 40 is engaged with the other end of the long hole 22 of the rotating lever 20, thereby preventing the slide lever 30 from further extending from the rotating lever 20, and the display 2 mounted on the other end of the slide lever 30 is appropriately spaced from the eyes of the user U.

In this way, the length of the slide bar 30 stretched and contracted in the rotating bar 20 can be adjusted, and such a structure can be used in various ways other than the above-described method.

As shown in fig. 5, when the user U lies on his side to rotate the rotating rod 20 around the inclined rotating shaft 12 in order to view the display 2, the display 2 is too close to the eyes of the user U, and thus the display 2 needs to be spaced slightly farther from the rotating rod 20, according to the present application, when the rotating rod 20 rotates, the sliding rod 30 automatically protrudes from the rotating rod 20 by its own weight, and the display 2 is separated from the rotating rod 20, so that a separate operation is not required to be spaced from the eyes of the user U.

In this way, the display 2 should match an optimal viewing distance with the eyes of the user U at the rotation position of the rotation lever 20 according to the posture or physical condition of the user U, and in the present application, since the sliding lever 30 is automatically extended and contracted only by rotating the rotation lever 20, the display 2 is automatically adjusted to the optimal viewing distance of the eyes of the user U, thus improving usability and the user U can view the display 2 in a comfortable posture.

The display stand according to an embodiment of the present application may further include a rotation control device 15, 23 capable of adjusting the position of the rotation lever 20 according to the rotation locus. As shown in fig. 6, the rotation control means 15, 23 includes a plurality of fixing grooves 15 provided at intervals in the circumferential direction on the outer circumferential surface of the inclined rotation shaft 12 of the fixing frame 10 and elastic fixing protrusions 23 provided on the rotation lever 20 and inserted into the fixing grooves 15. The elastic fixing protrusion 23 rotates around a rotation axis, not shown, to be inserted into the fixing groove 15, and is formed in a shape capable of being separated from the fixing groove 15 by an external force exceeding a predetermined force by a spring, not shown. As shown in fig. 1 and 4, even if the rotation lever 20 is positioned at the top of the rotation locus by the rotation control devices 15, 23, the rocking sideways or arbitrary rotation can be prevented.

The display stand according to an embodiment of the present application may further include a stopper 50 for limiting the rotation of the rotating lever 20. The stopper 50 may be provided on the rotating lever 20 or the fixed frame 10. As shown in fig. 6, the fixing frame 10 is provided with a stopper 50 protruding from the circumference of the fixing groove 15 on the outer circumferential surface of the inclined rotation shaft 12 to lock the fixing protrusion 23. Therefore, the rotating lever 20 can be effectively prevented from being excessively rotated and colliding with the installation wall 1 or surrounding objects.

On the other hand, in the present embodiment, one positioning pin 40 is inserted into the insertion groove 32 of the slide bar 30 through the long hole 22 of the rotating bar 20, but not limited thereto, various structures capable of adjusting the telescopic length of the slide bar 30 may be used. For example, another positioning pin may be directly connected to the insertion groove 32 of the sliding lever 30 to adjust the length of the sliding lever 30 inserted into the rotating lever 20. And the stopper 50 may have various shapes that restrict the rotation of the rotating rod 20, for example, since the stopper 50 protrudes laterally from the rotating rod 20 instead of the fixed frame 10 and contacts the mounting wall 1, the rotation of the rotating rod 20 may also be restricted.

Fig. 7 and 8 show a display stand according to another embodiment of the application. As shown, a monitor stand according to another embodiment of the present application is provided to manually extend and retract the slide bar 30 from the rotating bar 20.

That is, in the present embodiment, the slide lever 30 is configured to be manually moved in the rotating lever 20. For example, when the slide bar 30 is not stretched or contracted due to its own weight due to friction between the slide bar 30 and the rotating bar 20, the user may directly move the slide bar 30. In addition, even when the slide lever 30 does not slide for a desired length due to its own weight in the rotating lever 20, the user can directly move the slide lever 30.

For such manual extension and retraction, the slide bar 30 is provided with a handle 60, and the rotary bar 20 has a guide hole 24 extending in the longitudinal direction, so that the handle 60 of the slide bar 30 moves. As shown in fig. 7 and 8, the user U lying on the bed can easily grasp the handle 60 of the slide bar 30, and the handle 60 of the slide bar 30 protrudes inward with respect to the rotation locus of the rotating lever 20. At this time, it is preferable that the guide hole 24 of the rotating lever 20 is provided toward the center of the rotation locus with respect to the rotation locus.

In addition, the slide bar 30 may be configured to limit stretching and shrinking when the handle 60 is caught on the end of the guide hole 24 of the rotating bar 20. The length of the guide hole 24 can be appropriately adjusted according to the user U. In some cases, the extension and retraction length of the slide bar 30 may be adjusted by providing separate fixing means. On the other hand, since the slide bar 30 can be fixed by friction between the slide bar 30 and the rotating bar 20, the tensile length of the slide bar 30 can be adjusted without a separate fixing means.

In this way, when the user U lies in a bed to change the posture, the rotating lever 20 is rotated while holding the handle 60 of the sliding lever 30 so that the display 2 is located at a straight distance from the eyes of the user, and the sliding lever 30 can be extended and contracted in the rotating lever 20, the display 2 can be located at an optimal distance from the eyes of the user even if more different postures are taken, so that the user can view the display 2 in a more comfortable posture.

The present application described above is not limited to the above-described embodiments and drawings, and it will be apparent to those skilled in the art that various substitutions, modifications and changes may be made within the technical spirit of the present application.
