Description

[0001] The present invention relates to a folding mechanism for flat panel display,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for storing a flat panel display (a flat panel display (TV, monitor, etc. made of flat panels such as LCD, PDP, OLED, etc .; below flat panel) on a ceiling. , A bent frame for mounting a plate along a track regulated by a guide rail, supports and pulleys with the aid of a recoil and the force of a traction machine (Display Housing, hereinafter " frame ") is a device that can be moved on the basis of the second type lever and the balance to be stored on the ceiling or deployed to a viewing position for use. The object of the present invention is to enhance safety, usability of space and flexibility of interior arrangement and decoration by storing a flat plate occupying space and arrangement position unnecessarily when not in use.

In general, the ceiling storage of the flat plate is based on the movement of changing the vertical position of the flat plate to the horizontal position in order to overcome the limitation of the storage space.

The most intuitive way of changing the vertical position to the horizontal position is the hinge type (Hinge method), and most of them use the principle of the third class lever.

Therefore, the hinge type is required to receive more power in proportion to the higher the height of the ceiling to be stored and the larger the plate weight is heavier.

For this reason, the hinged ceiling storage device is practically applied only to a small flat plate having a low ceiling and a light weight, and is applied to an interior of a car or an airplane.

However, in homes, offices, or other indoor spaces with large ceilings and heavy weights, the requirements of the mechanism for the hinged ceiling enclosures using the principle of the third class lever have increased dramatically. Difficult to find

Currently, the commercially available large flat ceiling installation device adopts the method of fixing the flat panel itself to the ceiling, so if the installation location is low, it is vulnerable to safety, space utilization, and aesthetics. It is.

This invention is proposed to solve the above problems,

It is possible to operate efficiently with less force by changing the direction of force with pulleys and wires, and with the balance effect, it operates with less force as the storage progresses. Guide tracks, supports and bent frames interact to minimize the space required for operation and reduce the entry and exit of the ceiling.

By installing a recoil on the element, the maximum amount of force required to start the storage can be lowered so that a large flat plate can be stored on the ceiling even with a lower specification device.

Compared to the existing hinge type, the relatively small power, narrow working space and small entrance increase the freedom of installation of the ceiling storage device.

The ceiling storage device according to the present invention frees the place occupied by the flat plate when not in use, thereby securing additional space, increasing the degree of freedom of indoor space arrangement, and improving the interior aesthetics.

In order to achieve the above object,

Use the pulley effect to change the direction of the force with pulleys and strings to make use of the principle of class 2 levers, and to fix the strings to the lower connection points of the frame, and to place the support and force points farthest, to minimize the force in principle. Works.

The guide orbit keeps the support point and the force point far away while the frame is moving so that it can be operated with minimum force on the principle of the second class lever continuously even if the frame phase changes.

The principle of balance is to reduce the force required for the operation of the storage device by continuously moving the position of the working point in the direction of the support point during the storage movement of the frame.

When the frame tries to move downwards beyond the balance point on the principle of balance, the guide orbit controls the movement so that it is stable in the storage position.

Due to the pulley of the pulley, a situation that exceeds the balance point on the principle of balance is generated early and controlled using the guide track to reduce the interior space required for the maneuvering of the frame and to reduce the force required for the operation of the storage device compared to the conventional method.

The interaction between guide tracks, support points, and bent frames allows the ceiling storage device to operate while occupying minimal space, and the entrance and exit of the ceiling for storage is smaller than the conventional method such as hinge type.

Considering the fact that the frame requires the most force when maneuvering into the stowed position, a recoil is mounted on elements such as a hoist, a guide orbit, and the reaction force accumulated by gravity when deployed to the viewing position is used. Reduce the burden

When unfolding, the frame is fixed to the viewing position by the unfolding point of the guide track, the pedestal, and the lower connection point (strength point) of the file.

The effect obtained by this invention is

The principle of application for the ceiling storage of flat plates (second class, balance) requires the smallest force, so it is possible to store large flat ceilings even with a low specification device.

A single power source can carry out the entire process of storage and deployment.

Since the interior space required for maneuvering for storage and deployment is small, the degree of freedom in the installation position of the ceiling storage device is higher than that of the conventional method such as the hinge type.

Since the storage is buried, the restriction on the installation surface is small, so it can be installed on the window side or the entrance side.

It is compatible to switch the viewing side back and forth according to the user's choice.

Even if the size of the flat plate increases, the height change of the ceiling space is not large, and the change of the lower limit of the viewing angle of the viewer is small.

The force acting on the mold during storing and unfolding action acts on the sides and upper and lower back sides of the mold, so that the decorative bezel can be installed on the front side in the viewing direction.

There is a protective surface (silicone projection or velvety cushion pad) at the storage position to prevent the screen from sagging due to long-term horizontal storage.

The ceiling entrance for storage and deployment is small, which is good for aesthetics.

The present invention facilitates the ceiling storage of the flat plate through this effect, thereby ensuring an additional space in the room, to enhance the safety, to increase the degree of freedom of the layout of the interior space, and to effectively achieve the purpose of improving the interior aesthetics. It is a useful invention.

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

It should be understood that the embodiments are not intended to limit the scope of the invention, but merely as exemplifications, and that various modifications are possible without departing from the scope of the invention.

When explaining the basic principle applied to this invention step by step (Fig. 1),

(A) indicates the operation of the existing hinge type (Hinge method, mainly based on the principle of the third type lever), and the position of the power point can only be close to the hinge due to the limitation of the space in the ceiling. To illustrate. The higher the ceiling, the longer the frame, and the larger the plate, the heavier the weight, making it difficult to use a hinged enclosure that utilizes the third type of paper principle.

(B) describes the operation of the first and second type levers, showing that the operation of the device according to the principle of the first type lever in the narrow structure of the ceiling faces a problem similar to the hinge type of the third type lever. have. If the curved surface of the frame is used, the principle of the first type lever can be used, but it is inefficient than the method using the second type lever due to the limitation of the ceiling space. Although the principle of the second class lever can be applied, the force point is located in the interior space at the bottom of the flat plate, which shows a problem that simple application is difficult.

(C) illustrates the operation of the balance principle by the pulley. When the balance point is over the balance point, the deflection is explained in the opposite direction, and the moving point in the direction of the support point can be reduced gradually.

(D) shows the second lever, the principle of balance, and the guide orbit 200 how they interact and work together. This demonstrates that a mixture of (B) and (C) can be used to control the excessive operation to the other side using a guide orbit to obtain a phase change with the smallest force in principle.

(E) shows that the working principle of (D) minimizes the operation trajectory of the storage device with a frame 350 bent at the upper part thereof, so that the ceiling of the flat plate can be accommodated with the minimum force and working space for the present invention. In addition, it will be described that the curved frame can be stabilized at a position close to the vertical even when suspended only in the pulley 130 as compared to the straight frame.

The basic diaphragm (FIG. 2) of the ceiling storage device according to the present invention will be described and the process of the development from the storage position (a) to the viewing position (b) will be described below.

The storage device includes a hoisting machine 100, a guide track 200, a frame 300, a support stand, and a door. The hoisting machine includes a motor, a speed reducer 110, a recoiler 120, a pulley 130, and a string 140. It is composed of the main components and is the main drive that moves the storage device.

The hoisting machine is fastened to the upper connection point 450 and the lower connection point 440 of the frame and then wound around the pulley to connect with the frame in the form of a balance. The hoist may be positioned forward if necessary.

The guide track has a track groove 210 through which the wheel can move, the front end of which is a storage position fixing point 250, and the rear end 260 is a viewing position fixing point. The wheel of the frame is inserted into the track groove and connected to the frame, and the wheel moves along the track groove. The reaction machine 230 is provided at the viewing position fixing point 260.

The frame is a structure that mounts a flat plate and switches to a storage position and a viewing position, and has an orbital groove 320 at a side thereof and has an upper portion bent 350. The wheels of the supports 420 and 410 are inserted into the track grooves to restrict the movement of the frame by the supports. It is connected by the pulley and the string of the hoist.

The support is operated with the upper and lower limits to control the movement path of the frame during the movement along with the guide orbit 420 or to fix the movement of the frame (410) and to protect the surface of the plate (480).

The entrance is closed when the frame is stored, improving the aesthetics of the ceiling and opening when the frame is deployed.

The storage device having the above-mentioned diaphragm rotates the frame in the storage position (a) and pulls the string to pull the upper connection point 450 to move rearward. At the same time, the recoiler 120 installed in the hoisting machine operates and force begins to accumulate. The wheel of the frame moves the track groove of the guide track and is regulated by the support 420 so that the frame is developed into the optimal trajectory required. If the center of gravity is changed due to the balance effect caused by the pulley during the movement of the frame, the development continues by the weight of the frame without lifting the pulley. The pulley prevents excessive speed development by regulating the strings fastened to the lower connection points of the frame. As the pulley pulls the rope fastened to the lower connection point, the development of the frame continues. In the process of deployment, the guide tracks, supports, pulleys and strings are used to develop the frame, which takes up minimal operating space and minimizes the width of the entrance. As the wheel passes through a portion of the guide track, force is accumulated in the recoil 260 installed in the guide track. When the frame is deployed to the viewing position, the wheel 310 of the frame reaches the viewing position fixing point 260 of the guide track and stops to form the first fixed point. At the same time, the pulley that draws the rope stops and supports the lower fixed point with the rope, forming a second fixed point. Due to the curved shape of the frame, the support 410 is deployed to the maximum position, and the upper surface of the bent surface of the frame is pressed by weight to form a third fixed point, thereby stably fixing the frame to three fixed points at the viewing position. Done.

The movement from the viewing position (b) to the storage position operates in the reverse order and takes the greatest force in the initial stage of the maneuvering. At this time, the repulsive force by the reaction of the recoilers reduces the burden of the hoist and enables the operation with a smaller force. .

The hoist (Fig. 3)

It consists of a motor, a reducer, a pulley 130 and a string 140, and a recoiler 120.

The hoisting machine and the frame are connected to the upper connection point 450 and the lower connection point 440 by a rope wound around a pulley. Pulleys and strings are important elements that allow the frame to operate efficiently by the principle of the second lever and to reduce the force required by the principle of balance during maneuvering.

The pulley rotates in both directions with the force of the hoist and lifts and draws the string 140 in both directions. There are many ways to wind the pulleys, but basically there are two categories (A, B). B is simply spanned to make a groove to effectively transmit the rotational force of the pulley to the rope to widen the contact surface of the rope and the pulley or to have a chain structure (160,161).

(A) is advantageous to the force, but the strings can interfere with each other during operation, so it has a guide frame (170, Roller) to control the entry and exit and lifts the power point (consequently the frame) by diameter compared to (B). There is an advantage that can be taken. The upper connection point 450 to which the string is connected is equipped with a shock absorber 150 to adjust the relaxation of the string according to the shape of the frame during operation and to increase the tension of the string. The hoist has a recoiler 120 (Recoil) to alleviate this when the maximum load is taken during storage startup, which contributes to lowering the maximum load level of the hoist.

The guide track (Fig. 4) is an important component for regulating the trajectory of the movement of the frame when the storage device is operated, and there are the track groove 210 and the storage position fixing point 250 and the viewing position fixing point 260 at both ends thereof. A recoiler 230 is installed at the fixed position side.

The guide track and the frame are connected to the wheel 310 of the frame is inserted into the track groove of the guide track (b), the frame is wheeled by the track groove of the guide track to move on the track and the trajectory of the movement is controlled. The guideway recoil 230 is compressed by the weight and hoist of the frame when the frame is deployed to the viewing position, accumulates the force, acts as a buffer, and provides the maximum load on the hoist with repulsive force when starting the storage operation. Lower it.

According to the balance principle, the guide track prevents the frame from being oriented in the opposite direction beyond the balance point and continuously maintains the maximum distance between the supporting point and the force point in the second type lever while the frame is moving.

The trajectory of the frame drawn by the guide track, the curved portion 350 of the frame, and the support 420 is smaller than that of the linear frame, and thus occupies a small amount of space required during operation.

The trajectory of the string (D) shows how the string works according to the shape of the back of the pillar of the mold as the development progresses. When the frame is lowered by a certain degree (690), the frame and the line are in close contact and the phase of the line is changed.

The frame (Fig. 5) is a part for mounting the flat plate and moving the space for storage and deployment in the ceiling storage device. In order to secure sufficient strength, the structure is strengthened by the strong installation of cross lines 340.

The frame is connected by inserting the wheel structure into the guide track. In addition, there is a track groove on the side of the frame is inserted into the wheels of the support (410,420) is connected to and from the track 320 to limit the movement of the frame.

The frame is connected to the pulley is fastened to the pulley to the upper connection point 450 and the lower connection point 440. The frame hangs like a balance by the rope on the pulley and is operated by the rotation of the pulley, which makes use of the principle of balance.

The curved portion 350 of the mold reduces the movement trajectory of the mold to reduce the occupancy of the interior space during operation for storage and deployment, to reduce the width of the door of the ceiling, and to form a fixed point at the point where the support is fully developed. .

The frame forms the first fixed point by the wheels and guide tracks when the frame is fixed to the viewing position, the second fixed point by the rope fixed to the pulley and the lower connection point, and the frame at the maximum deployment point of the support 410. It is seated by forming a third fixed point with the weight of.

The curved frame allows the flat plate to be developed vertically, depending on the pulley and the string, compared to the straight frame, and in the maneuver for deployment, it becomes the support point 691 of the string to increase the lifting force by the pulley.

The back of the frame has a raised portion 351, which can be installed to reinforce the structure by installing a cross beam, and also has the effect of increasing the lifting force of the rope by the pulley by changing the lifting angle (Fig. 4D) according to the position at the time of starting the frame. . There is a groove (330) that can be inserted into the line in contact with the rear line of the frame, when the deployment at a certain position (Fig. 4-690) after the line goes into the groove of the frame, foreign matter caught between the frame and the line It also improves aesthetics by preventing lines from being seen when deployed to the viewing position.

Support (Fig. 6) is to move within the upper and lower limits of the frame by limiting the movement of the frame up and down (420), open the ceiling door when the frame is deployed (410), when the frame reaches the deployment position of the frame The weight is bent by the curved surface and becomes one of the fixing points of the frame due to the expansion limit of the reaction machine 430. When the frame reaches the storage position and is fixed, the screen of the flat plate is prevented from sagging of the flat plate.

The bottom connection point 440 of the frame is a support that bears the load of the frame when deployed at the viewing position by a fastened string.

Supports 410 and 420 are connected to the frame by inserting a wheel into the side groove of the frame and moves along the track groove installed on the side of the frame during the movement of the frame.

      The doorway (Fig. 7) is opened and closed by two doors and there is a door 710 that opens only in front of the frame when it is deployed to the viewing position and a door 720 that is opened only when it is fixed to the storage or viewing position. With two doors at the entrance, the door opens to reduce the area covering the front of the frame.

(A) the frame reaches the storage position and lifts the support 410, the door 710 is closed and fixed, (C) the frame pushes the wheel 490, the door 720 is opened and the support ( 410 is down and the process of opening the door 710 by pressing down.

(B) The door 710 is opened to the maximum allowed by the recoil 430 when the frame is deployed to the viewing position and supports the frame pressed by weight, and forms a third fixed point to fix the frame.

The door 720 may also be opened by a string connected to the pulley and the frame.
