In each of the drawings, the same reference numerals, in particular, the tens and ones digits, or the same digits, tens, ones, and alphabets refer to members having the same function, and unless otherwise specified, each reference in the drawings. The member referred to may be regarded as a member conforming to these criteria.

The ceiling-mounted display mounting apparatus according to the present invention is not absolute, but for a large display (A1) of 40 inches or more shown in Figs. 1 to 5, for a medium size display (A2) of 20 inches to 30 inches shown in Fig. 6, And although it can be configured in various ways, such as a small display (A3) of less than 20 inches class shown in Figure 7, the driving mechanism is about the same,

Portions that are not significantly different with respect to the driving mechanism in relation to the mounting apparatus A2 and A3 for the small and medium size display are replaced with the description of the mounting apparatus A1 for the large display shown in FIGS. 1 to 5. Some references are omitted for convenience.

As shown in FIGS. 1 to 5, the mounting apparatus A1 for the large display D is largely folded to store or vertically unfold the base 10, the display mounting member 20, and horizontally on the ceiling. Means 30, the spreading link 50 for transmitting the operation of the spreading means to the mounting member, the lifting means 40 for the unfolding mounting member, the mounting member by the continuous operation of the lifting means And an angle adjusting means 60 for tilting the display.

First, the base 10 is fixed to the interior of the building or the ceiling of the vehicle, the mounting member 20 can be applied to a frame type applied to a large display as shown in Figure 1, and a small and medium display as shown in Figure 6 or 7 There is a panel type, which has no absolute meaning and can be appropriately selected as needed.

Unfolding means 30 to be folded in a horizontal state to the ceiling or to expand vertically the first motor (31) mounted on the base 10, a reducer (31a) for reducing and transmitting the driving force of the motor, The first feed screw 33 is pivoted by the first motor 31, and the first nut 35 is a circular motion and a linear motion in accordance with the rotation of the first feed screw.

Although not shown, the motor 31, the reducer 31a, and the first screw 33 may be replaced with a hydraulic or pneumatic cylinder, and the first nut 35 may be replaced with a piston as necessary.

The motor and the cylinder and the hydraulic (or pneumatic) circuit configuration may be collectively referred to as a first drive body mounted on the base,

The nut and the piston may be collectively referred to as a first displacement body that linearly moves by the first driving body.

In the drawing again, the conveying screw 33 may be a simple bolt type, and is alternatively known in the art, such as `` Bowl Screw Nut '', for example, Patent Publication No. 1992-0000544 (1992.01.16) for smoother turning and prevention of noise. A ball screw may be employed or an interposed bearing between the screw and the nut may be applied, and the same may be applied to the second transfer screw 43 and the second nut 45 constituting the lifting means 40. .

The nut 35 is in a circular motion and a linear motion according to the turning of the screw 33, but the rotational force should not be transmitted to the spreading link 50, in particular the second arm 53, the nut 35 ) Shall be connected to other members in such a way as to allow idling.

To this end, the nut 35 is accommodated in the guide member 37 in the form of idling, and the guide member is connected to the second arm 53 of the unfolding link 50.

In addition, in the mounting apparatus A2 for the medium-sized display as shown in FIG. 6, the guide member 37 is configured to perform a horizontal linear movement along the guide rail 11 provided in the base 10, thereby enabling stable operation.

Next, the lifting means 40 has a case 40A rotatably coupled to the lower portion of the base 10 through the bracket 40a,

In accordance with the rotation of the second motor 41 built into the case, the reducer 41a for reducing and transmitting the driving force of the motor, the second transfer screw 43 pivoted by the second motor, and the first transfer screw It includes a second nut 45 for circular motion and linear motion,

A first guide rail R1 and a second guide rail R2 shorter than the first guide rail are formed in the case 40A.

As the nut 45 moves up and down as the screw 43 rotates, the display is moved up and down,

The tilt angle of the display can be adjusted due to the difference in the relative lengths of the rails R1 and R2.

In addition, although not shown, the motor 41, the reducer 41a, and the second screw 43 may be replaced with a hydraulic or pneumatic cylinder, and the second nut 45 may be replaced with a piston as necessary.

The motor and the like and the cylinder and hydraulic (or pneumatic) circuit configuration may be collectively referred to as a second drive body pivotally coupled to the base,

The nut and the piston may be collectively referred to as a second displacement body having a linear motion by the second driving body and having a guide rail.

Again, since the rotational force of the second nut 45 should not be transmitted to the pivot link 61, it is preferable to introduce a relay member 47 for receiving the nut to allow mutual idling.

Next, the mounting member 20, and eventually the unfolding link 50 for unfolding and folding of the display, opens the case 40A of the base 10 and the elevating means 40. FIG. It consists of a first arm 51 which connects, and a second arm 53 which connects the case 40A and the first nut 35 to each other.

If the displacement body and the driving body of the above-mentioned concept consists of a cylinder and a piston, the first arm connects the cylinder (or lower base) that forms the base and the first displacement body, and the second arm connects the cylinder. And the piston forming the first driving body.

In the large display mounting apparatus A1 of FIG. 1, the elevating means 40 is provided in two sets in a symmetrical position. Each set of the cases 40A is connected by a connecting bar 49. The bar 49 is connected to each of the arms 51 and 53 of the extending link 50.

The spreading means and the set of lifting means can be variously selected in order to provide an inexpensive mounting device while avoiding problems with the size, installation environment, and operation of the display, and connecting the spreading means and the lifting means. The number of parts and the structure of the spreading link for the angle adjusting means for connecting the lifting means and the mounting member and the lifting means can be variously selected.

For this purpose, the spreading means and the lifting means are each one of the medium and small display mounting apparatuses A2 and A3 of FIGS. 6 and 7, and each arm 51 and 53 of the spreading link 50 and Connecting bar 49 is connected to the protrusion pin shape provided on both sides of the case 40A constituting the lifting means,

In the mounting apparatus A2 of FIG. 6, the guide member 37 connected to the first nut 35 of the spreading means moves along the guide rail 11 provided on the base 10 for stable operation. It is different from the mounting apparatus A3 for a small display of FIG.

In addition, in the small display mounting apparatus A3 of FIG. 7, unlike the devices A1 and A2 of FIGS. 1 and 6, the expansion means 30 of the mounting member 20 may reduce the power of the motor 31. 31a), the case of the lifting means by the expansion link 135 which is transmitted to the bevel gear 133 provided at the end of the output shaft of the reducer, and including a gear to form a cross-axis gear with the bevel gear 133 There is a difference in that the shape 40A can be unfolded and folded. However, the concepts of the elevating means and the angle adjusting means for elevating and tilting the unfolding mounting member 20 are basically applied.

In FIG. 7, the turning concept of the elevating means case 40A by the gear 133 and the extending link 135 of the spreading means is exaggeratedly expressed, but the display, the mounting member, and the lifting means are pivoted by the gear connection. It is merely an explanation of the concept of folding, and it is possible to design and produce engineering-realistically under these concepts.

Next, after unfolding the display by using the spreading means 30, the tilting means 60 for tilting the display in a state where the display is lowered to an appropriate height by using the elevating means 40 is provided.

 Connecting the second nut 45 and the mounting member 20 forming the second driving body of the elevating means 40 and the shaft pin (61a) moving along the first guide rail (R1) of the case (40a) Swivel link 61 provided (the shaft pin and the slew link is connected by a band 61b (see Fig. 1),

It comprises a slide pin (63) connecting the case 40A of the lifting means 40 and the mounting member 20 and coupled to the second guide rail (R2).

In the above description, two arms of the unfolding link 50 connecting the base 10 and the first nut 35 of the unfolding means and the case 40A of the elevating means 40, in particular, the connecting bar 49, are provided. (51) (53) is a form that can be rotated,

The base 10 and the case 40A of the elevating means can also be axially rotated by the brackets 40a.

In addition, the upper coupling member 21 of the mounting member 20 and the pivot link 61, and the first hi-link and the second nut 45 of the elevating means, in particular the nut is accommodated in a state capable of idling The connecting structure of the relay member 47 is also capable of rotating the shaft,

The band 63a connecting the slide pin 63 constituting the angle adjusting means and the lower coupling member 23 of the mounting member 20 is fastened to the coupling member 23 in a rotatable manner by the shaft pin. It is.

Operation of the ceiling-mounted display mounting device (A1) according to the present invention described above is

First, in FIG. 2, in the state in which the mounting member 20 is folded and received in a horizontal state on the base 10 fixed to the ceiling.

As shown in FIGS. 1 and 3, the first motor 31 of the spreading means 30 is driven by operation of a button (or switch) provided in a remote controller or other control panel, and is passed through the reduction gear 31a. When the first transfer screw 23 is turned, as the first nut 35 coupled thereto moves toward the motor 31,

The second arm 53 of the spread link 50 coupled to the guide member 37 for receiving the first nut 35 is folded while moving toward the first arm 51,

Accordingly, as the connecting bar 49 connecting the two cases 40A of the elevating means 40 is interlocked, the case 40A is unfolded by rotating the bracket 40a about the shaft.

The mounting member 20, which was coupled to the case 40A, is unfolded, so that the display is upright.

Subsequently, as shown in FIG. 4, the second motor 41 of the lifting means 40 is driven by the operation of another button or an automated continuous operation, and the second transfer screw 43 is passed through the reduction gear 41a. Turns, and the second nut 45 is lowered while interlocking,

The pivot link 61, which is connected to the relay member 47 accommodating the nut 45 to idle, descends on the first guide rail R1 of the case 40A through the shaft pin 61a. follow,

The mounting member 2 is lowered, and of course, the slide pin 63 is also lowered along the second guide rail R20.

Next, as shown in FIG. 5, the tilting operation of the display D is shorter than the first guide rail R1 formed in the case 40A of the lifting means 40, so that the second guide rail R2 is shorter.

Since the slide pin 63 first comes into contact with the bottom of the second rail R2, the slide pin 63 can no longer be lowered.

On the other hand, since the second nut 45, the relay member 47, and the pivot link 61 descending along the first rail R1 may descend further,

While the mounting member 20 pivots by using the lower coupling member 23 coupled to the band 63a as an axis,

The pivot link 61 that was folded is unfolded to tilt the mounting member 20.

When the shaft pin 61a connecting the relay member 47 and the pivot link 61 is caught to the lower end of the first guide rail R1, the mounting member 20 and eventually the display achieve the maximum tilting angle.

When storing the ceiling of the display, unlike the previous unfolding-lowering-tilting process, the operation is also performed in an up-standing-folding process by operation of a remote controller or other control panel.

That is, when the second motor 41 of the elevating means 40 is rotated in reverse, the mounting means 20 is raised in the state in which the nut 45 is tilted while being raised as the bolt 43 is rotated. Done.

When the slide pin 63 comes in contact with the upper end of the second guide rail R2, the slide pin 63 is no longer liftable.

Since the nut 45, the relay member 47, and the pivot link 61 may be further raised, the mounting member 20 is folded while turning the lower coupling member 23 as an axis.

When the shaft pin 61a positioned on the nut 45 is caught by the upper end of the first guide rail R1 and cannot rise any more (or stops due to the length limit of the pivot link 61), the mounting member is completely Upright.

Subsequently, the first transfer screw 33 is turned by the reverse rotation of the first motor 31 of the spreading means, and the first nut 35 is separated from the motor.

The second arm 53 of the unfolding link 50 is extended away from the first arm 51 to pull the connecting bar 49 connecting the case 40A so that the case of the lifting means The bracket 40a is pivoted about its axis and folded,

Therefore, the mounting member 20 is folded to displace the display in a horizontal state with the ceiling.

In the above description of the present invention, a mounting apparatus having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and replaced by those skilled in the art. It should be interpreted as falling within the protection scope of the invention.
