DETAILED DESCRIPTION

A display mounting device according to embodiments is described below with reference to the attached drawings. In the drawings, the same reference signs are given to the same or similar components, and the description of such components will not be repeated.

First Embodiment

FIG.1illustrates a side view of a display mounting device1according to a first embodiment. As illustrated inFIG.1, the display mounting device1is installed on a floor surface2,FIG.2Ais a front view of the display mounting device1without the display3mounted thereon. The display3can be detachably mounted on the display mounting device1. The specific structure of the display mounting device1is described below.

As illustrated inFIGS.1and2A, the display mounting device1includes a supporting pillar11(11a,11b), a display fixture12, a base13, and a supporting pillar support14(example of a supporting pillar fixture).

The base13is, for example, a flat metal plate which is installed on a floor surface2.

FIG.2Bis a perspective view of the rear side of the display mounting device1illustrated inFIG.2A, mainly illustrating the display fixture12. As illustrated inFIG.2B, the display fixture12includes a display coupling121and a pair of supporting pillar couplings122.

The display coupling121is made of a plate-shaped member having a rectangular-shaped opening121a. The display coupling121is fixed to the rear side of the display3with screws or the like (not illustrated).

The pair of supporting pillar couplings122protrudes from the edge of the opening121aof the display coupling121in a direction opposite to the display3. Specifically, the supporting pillar couplings122are connected to a pair of sides of the opening121agenerally parallel to a direction (Z-axis direction) perpendicular to the floor surface2(FIG.1). The pair of supporting pillar couplings122is fixed to the upper supporting pillar11awith screws120n.

FIG.3is a rear view of the display mounting device1.FIG.4Ais an enlarged view of a lower supporting pillar11band the supporting pillar support14.FIG.4Bis a perspective view mainly illustrating the rear side of the supporting pillar support14.

As illustrated inFIG.3, the supporting pillar11includes an upper supporting pillar11aand the lower supporting pillar lib connected to each other. The supporting pillar11is rotatable within a range of angles between a first state in which the supporting pillar11is generally perpendicular to the floor surface2and a second state in which the supporting pillar11is generally parallel to the floor surface2. The upper and lower supporting pillars11aand11beach include a plane1101(1101a,1101b) and a pair of protrusions1102(11.02a,1102b) connected to the plane1101.

The plane1101is generally parallel to the display coupling121, and the protrusions1102are generally parallel to the supporting pillar couplings122. The plane1101(1101a,1101b) and the protrusions1102(1102a,1102b) constitute a recess110(110a,110b) on the rear side (negative X-axis direction) of the supporting pillar11. By routing cables (not illustrated) for the display3along an extending direction of the recess110, the cables can be hidden on the rear side of the supporting pillar11.

The pair of protrusions1102aof the upper supporting pillar11ais fixed to the pair of display couplings121with screws or the like (not illustrated) at a portion opposite to the lower supporting pillar lib.

The lower supporting pillar lib is mounted on the base13. The pair of protrusions1102bof the lower supporting pillar lib is fixed to the supporting pillar support14with screws11n(FIG.4A) at a portion opposite to the upper supporting pillar11a.

In the present embodiment, a portion at which the display coupling121is connected to the upper supporting pillar11ais an example of a first end of the supporting pillar11, and a portion at which the supporting pillar support14is connected to the lower supporting pillar11bis an example of a second end of the supporting pillar11.

As illustrated inFIG.4A, the protrusions1102bof the lower supporting pillar lib each have a notch111and a guide112. The notch111is a recess of each protrusion1102bextending from an end opposite to the plane1101b(seeFIG.3) toward the plane1101b. The guide112is a portion of each protrusion1102bat which a part of the end of the protrusion1102bopposite to the plane1101bis slanted toward the notch111. The notch111and the guide112have a function of vertically moving a shaft141which will be described later. In the present embodiment, the shaft141, the notch111, and the guide112(example of a sliding mechanism) constitute an example of a locking mechanism.

As illustrated inFIGS.4A and4B, the supporting pillar support14is mounted on the base13. The supporting pillar support14includes a coupling member140, the shaft141, a spring142(example of a rotation aid and elastic member), and a spring fixing member143.

The coupling member140includes a plane1401and shaft supports1402connected to the plane1401. The plane1401is generally parallel to the plane1101bof the lower supporting pillar11b, and the shaft supports1402are generally parallel to the protrusions1102bof the lower supporting pillar11b. The plane1401and the shaft supports1402overlap with the lower supporting pillar lib in the first state in which the supporting pillar11is generally perpendicular to the floor surface2. An end point P of each of the shaft supports1402located on the floor surface2side overlapping with the lower supporting pillar11bfunctions as a fulcrum to rotate the supporting pillar11. In other words, in the present embodiment, the end point P is an example of a rotation support that allows the supporting pillar11to rotate between the first state in which the supporting pillar11is generally perpendicular to the floor surface2and the second state in which the supporting pillar11is generally parallel to the floor surface2.

The shaft supports1402each have a groove14arecessed from an end opposite to the base13toward the base13. The shaft.141is crossed between the two grooves14a. The shaft141is a rod-like member longer than the length between the grooves14a. In the state illustrated inFIG.4Ain which the lower supporting pillar lib is fixed to the supporting pillar support14, a width of the notch111from a tip1121on the notch111side of the guide112in the direction toward the plane1101b(X-axis direction) is equal to the width of the groove14a.

One end of the spring142is fixed at an approximately center of the shaft141. The other end of spring142is provided with a hook1421. The spring fixing member143is fixed to the base13, and has a hole (not illustrated) in which the hook1421of the spring142is hooked. As illustrated inFIGS.4A and411, the spring142has a natural length in a state in which the shaft141is placed at the end portion of the grooves14aon the base13side, that is, the first state in which the supporting pillar11is generally perpendicular to the floor surface2. In other words, the shaft141is rested at an end position of the grooves14aon the base13side in the first state to fix the supporting pillar11in place.

Next, the operation of removing the display3mounted on the display mounting device1is described by referring toFIGS.5to7.

FIG.5illustrates a state in which the supporting pillar11is rotated toward the floor surface2from the first state illustrated inFIG.1. To rotate the supporting pillar11toward the floor surface2, the screws11n(FIG.4A) that connect the lower supporting pillar11bto the supporting pillar support14are removed. Once the screws11nare removed, the supporting pillar11can be rotated toward the floor surface2using the end point P (rotation support) of the base13side of the coupling member140as the fulcrum. As illustrated inFIG.5, when the supporting pillar11is rotated toward the floor surface2, the tip1121of the guide112of the lower supporting pillar11bpushes up the shaft141, and the spring142is extended. The extended spring142pulls the shaft141toward floor surface2. Accordingly; a force in the direction of the base13is applied to the tip1121of the guide112which is in contact with the shaft141, making it difficult for the supporting pillar11to fall vigorously toward the floor surface2side.

FIG.6illustrates a state in which the supporting pillar11is farther rotated toward the floor surface2from the state illustrated inFIG.5. When the supporting pillar11is rotated farther toward the floor surface2from the state illustrated inFIG.5, the position of the shaft141lowers along the guide112from the tip1121of the guide112of the lower supporting pillar11b. Since the shaft141is in contact with the guide112of the lower supporting pillar lib, a force in the direction of the base13is applied to the guide112in the direction of the base13, making it difficult for the supporting pillar11to fall vigorously to the floor surface2side.

FIG.7illustrates a second state in which the supporting pillar11is collapsed from the state illustrated inFIG.6to the floor surface2. In the second state, the shaft141is placed at the end of the grooves14aon the floor surface2side, and the spring142has a natural length. In this state, the display3can be removed from the display mounting device1by removing screws (not illustrated) connecting the display fixture12with the display3.

To mount the display3on the display mounting device1, it is simply necessary to reverse the procedure for removing the display3described above. Specifically, the display3is first placed on the floor surface2with the rear side of the display3facing up so that the display3is set in the second state in which the supporting pillar11is generally parallel to the floor surface2. The rear side of the display3is then connected to the display coupling121with screws. Accordingly, the display mounting device1is in the state illustrated inFIG.7.

In the state illustrated inFIG.7, the supporting pillar11is rotated until the supporting pillar11is perpendicular to the floor surface2using the end point P of the coupling member140as the fulcrum. This allows the shaft141to be lifted along the guide112, as illustrated inFIG.6. In rotating the supporting pillar11farther until the supporting pillar11is perpendicular to the floor surface2, the shaft141is pushed up by the tip1121of the guide112, as illustrated inFIG.5, and the position of the shaft141is moved along the notch111, as illustrated inFIG.4A, In other words, the shaft141is placed at the end of the grooves14aon the floor surface2side. At this time, the shaft141is rested between the guide112and the notch111to fix the supporting pillar11, thus making it difficult for the supporting pillar11to fall over even when the hand is off from the supporting pillar11. In this state, the lower supporting pillar11and the coupling member140are fixed with the screws11nto fully fix the supporting pillar11to the supporting pillar support14.

In the present embodiment, the display mounting device1includes the shaft141and the spring142in the supporting pillar support14, and the guide112in the lower supporting pillar11b. Accordingly, in rotating the supporting pillar11toward the floor surface2, the supporting pillar11is not likely to fall vigorously to the floor surface2side, achieving safe rotating movement of the supporting pillar11.

In the present embodiment, the supporting pillar11can be collapsed to the floor surface2to mount the display3, and the supporting pillar11can be rotated to stand up with the display3being mounted. This facilitates mounting the display3, when it is relatively lightweight, by one person.

Second Embodiment

FIG.8is a side view of a display mounting device1A according to a second embodiment. InFIG.8, the same reference signs are given to the same components as those illustrated in the first embodiment. In the following, the components different from those of the first embodiment will be mainly described.

In the present embodiment, as illustrated inFIG.8, the display3is mounted on the wall4by hooking the display mounting device1A to a wall-side bracket40installed on the wall4. The display mounting device1A includes a supporting pillar21(upper supporting pillar21a, lower supporting pillar21b), a display fixture12A, a height adjustment screw16, and a supporting pillar support17(example of a supporting pillar fixture).

FIG.9Ais a rear view of the display mounting device1A. The display fixture12A includes a display coupling121A and a pair of wall couplings122A connected to the display coupling121A.

The display coupling121A is generally parallel to the rear side of the display3and has a rectangular shape. A part of the display coupling121A located on the floor surface2side is connected to the upper supporting pillar11awith screws (not illustrated).

The pair of wall couplings122A is connected to a pair of sides of the display coupling121A generally parallel to the a direction (Z-axis direction) perpendicular to the floor surface2. The pair of wall couplings122A each has two vertically spaced hooks1222formed across the display coupling121A and protruding in a direction (negative Y-axis direction) opposite to the display3. The hooks1222are hooked on the wall-side bracket40FIG.8).

An upper supporting pillar21A (example of the first supporting pillar) and a lower supporting pillar21B (example of a second supporting pillar) each include a plane2101(2101a,2101b) and a pair of protrusions2102(2102a,2102bconnected to the plane2101. The plane2101is generally parallel to the display coupling121A, and the protrusions2102are generally parallel to the wall couplings122A. The plane2101(2101a,2101b) and the protrusions2102(21.02a,21.02b) constitute a recess110(110a,110b). The plane2101aof the upper supporting pillar21ahas a hole21hthrough which a cable L of the display3is routed. By routing the cable L through the hole21h, the cable L can be hidden in the recess110of the supporting pillar21.

FIG.9Bis an enlarged view of the lower supporting pillar21band the supporting pillar support17of the display mounting device1A. As illustrated inFIG.9B, the protrusions2102bof the lower supporting pillar21bare fixed to the supporting pillar support17with screws21n. The protrusions2102beach have a notch211at the end of the floor surface2side. The notch211is a recess at the end of the protrusion2102bon the floor surface2side. In the first state in which the supporting pillar21is generally perpendicular to the floor surface2, the notch211overlaps with a notch172of the supporting pillar support17, which will be described later, to form a space between the notches211,172and the floor surface2to route the cable L. In other words, the cable L passes through the recess110in the supporting pillar21and extend through the notches211,172to be pulled out of the supporting pillar21. In the present embodiment, the recess110of the supporting pillar21is an example of a wiring compartment, and the notch172is an example of an opening that communicates with the wiring compartment.

FIG.10is an enlarged view of the connected portion of the upper and lower supporting pillars21a,21b. As illustrated inFIG.10, the upper and lower supporting pillars21a,21bare connected so that a portion of the upper supporting pillar21aoverlaps with a portion of the lower supporting pillar21b. Specifically, a portion of the upper supporting pillar21ais placed over a portion of the lower supporting pillar21b. The plane2101aof the upper supporting pillar21ahas a slide hole21sat a portion on the lower supporting pillar21bside.

A height adjustment screw16is fitted into the slide hole21S. The size of the screw head of the height adjustment screw16is larger than a horizontal width (width in the Y-axis direction) of the slide hole21s.

The height (length) of the entire supporting pillar21is adjusted by changing the position of the height adjustment screw16and the slide hole21s. Specifically, to adjust the height of the supporting pillar21, the height adjustment screw16is loosen to shift the position of the slide hole21sand is then tighten, thus changing the length of the overlap between the upper and lower supporting pillars21aand21band adjusting the height of the entire supporting pillar21. In other words, the height adjustment screw16and slide hole21sin the upper supporting pillar21aconstitute an example of a height adjustment mechanism.

FIG.11is an enlarged perspective view of the portion of the supporting pillar support17illustrated inFIG.9. As illustrated inFIG.11, the supporting pillar support17includes a wall contact portion17aand a pair of supporting pillar fixing portions17bconnected to the wall contact portion17a. In the supporting pillar support17, the wall contact portion17aand the supporting pillar fixing portions17bmay be integrally molded or may be formed separately and connected.

The wall contact portion17ais generally perpendicular to the floor surface2and is in contact with the wall4. The wall contact portion17ahas a recess171which is partially open on the floor surface2side.

The pair of supporting pillar fixing portions17bis connected generally perpendicularly to the wall contact portion17aat the edge of the recess171of the wall contact portion17a. More specifically, the pair of supporting pillar fixing portions17bis connected to a pair of sides of the recess171, the pair of sides being generally parallel to the direction (Z-axis direction) perpendicular to the floor surface2. The pair of supporting pillar fixing portions17bis fixed to the pair of protrusions2102bof the lower supporting pillar21bwith the screws21n(FIG.9B). The supporting pillar fixing portions17beach have the notch172. The notch172is an arched recess at the end of the supporting pillar fixing portion17bon the floor surface2side.

The supporting pillar21can be rotated by removing the screws21n(FIG.9B) that fix the pair of supporting pillar supports17to the pair of protrusions2102b, In other words, the supporting pillar21is rotated about an end point P1(example of the rotation support) of each supporting pillar fixing portion17hon the floor surface2side as the fulcrum.

Next, the operation of removing the display3mounted on the display mounting device1A is described.

In the state illustrated inFIG.8, the screws21n(FIG.9B) fixing the pair of supporting pillar supports17to the pair of protrusions2102bare removed. Subsequently, using the end point P1(FIG.11) of each supporting pillar fixing portion17bas the fulcrum, the supporting pillar21is rotated toward the floor surface2.FIG.12illustrates a state in which the supporting pillar21is rotated toward the floor surface2from the state illustrated inFIG.8. The rotation of the supporting pillar21causes the hooks1222of the display mounting device1A to be disengaged from the wall-side bracket40, thus tilting the supporting pillar21toward the floor surface2.

FIG.13illustrates the second state of the supporting pillar21changed from the state illustrated inFIG.12. As illustrated inFIG.13, by farther rotating the supporting pillar21from the state illustrated inFIG.12, a portion of the plane2101bof the lower supporting pillar21band a portion of the display3are brought into contact with the floor surface2. In this state, the display3can be dismounted from the display mounting device1A by removing the screws (not illustrated) connecting the display fixture12A and the display3.

To mount the display3on the display mounting device1A, contrary to the above, the supporting pillar21is rotated toward the wall4to the first state, Subsequently, the height adjustment screw16is loosen to adjust its position so that the height of the hooks1222of the display mounting device1A match the height of the wall-side bracket40, thus adjusting the height of the entire supporting pillar21.

After adjusting the height of the entire supporting pillar21, the supporting pillar21is rotated toward the floor surface2to the second state, and the rear side of the display3placed on the floor surface2is connected to the display coupling121A with screws. This brings the display mounting device1A to the state illustrated inFIG.13.

In the state illustrated inFIG.13, the supporting pillar21is rotated toward the wall4side using the end point P1of each supporting pillar fixing portion17bas the fulcrum. This causes the supporting pillar21and the display3to move away from the floor surface2, as illustrated inFIG.12. Furthermore, using the end point P1of each supporting pillar fixing portion17bas the fulcrum, the supporting pillar21is rotated toward the wall4to bring the display mounting device1A into the second state (FIG.8). Since the heights of the hooks1222of the display mounting device1A are adjusted to the height of the wall-side bracket40, the hooks1222can be easily hooked on the wall-side bracket40in the second state. In this state, the protrusions2102bof the lower supporting pillar21bare fixed to the supporting pillar fixing portions17bwith the screws21n(FIG.9B), thus fixing the supporting pillar21to the supporting pillar fixing portion17b.

In the present embodiment, the height of the entire supporting pillar21can be adjusted by adjusting the position of the height adjustment screw16. The height of the entire supporting pillar21can be adjusted before the display3is mounted on the display mounting device1A so that the height of the wall-side bracket40matches the heights of the hooks1222of the display fixture12A. Adjusting the length of the supporting pillar21in advance facilitates hooking the hooks1222on the wall-side bracket40when the supporting pillar21is made to stand perpendicularly from the floor surface2after the display3is mounted on the display mounting device1A.

In the present embodiment, the cable L is routed through the recess110of the supporting pillar21, allowing the cable L to pass through the notch211of the lower supporting pillar21band the notch172of the supporting pillar support17and be pulled out to the outside of the supporting pillar21. In this way, the wiring can be routed without compromising the aesthetics of the space where the display3is located.

The supporting pillar21can be rotated using the end point P1of the supporting pillar fixing portions17bas the fulcrum. This facilitates mounting the display3, when it is relatively lightweight, by one person.

The embodiments of the display mounting device according to the present disclosure have been described. The display mounting device is not limited to those described in the above embodiments, and can be implemented in various forms without departing from the scope and spirit thereof. The drawings mainly illustrate the constituent components schematically for easier understanding, and those illustrated in the drawings are different from actual ones in terms of thickness, length, number, and the like. The shapes, dimensions, and the like of individual constituent components illustrated in the above embodiment are merely examples and are not particularly limited, and various changes can be made without generally departing from the effect, of the present disclosure.

Modification

(1) The supporting pillar support17in the second embodiment may be replaced by the supporting pillar support14in the first embodiment. This allows for safer rotating movement of the supporting pillar21. The supporting pillar11and supporting pillar support14in the first embodiment may be replaced by the supporting pillar21and supporting pillar support17in the second embodiment. This allows for the height adjustment of the entire supporting pillar and also allows the cable L of the display3to be pulled out from the inside to the outside of the supporting pillar.

(2) In the first and second embodiments, the supporting pillar supports14,17are fixed to the lower supporting pillars11b,21bwith the screws11n,21n, respectively. Alternatively, the supporting pillar supports14,17may be fixed to the lower supporting pillars11b,21b, respectively, using, for example, an elastic member.

FIG.14is a schematic diagram illustrating the first state of a display mounting device1B according to a first modification.FIG.15is a schematic cross-section view cut along line XV-XV of the display mounting device1B illustrated inFIG.14.

As illustrated inFIG.15, the display mounting device1B includes a supporting pillar31and a supporting pillar support19. Like the supporting pillars11and21, the supporting pillar31is formed by connecting upper and lower supporting pillars, although not illustrated, and includes a plane3101and a pair of protrusions3102. The pair of protrusions3102each has an opening31a.

The supporting pillar support19includes a plane1901, a pair of protrusions1902, and a pair of fixing members191. The plane1901overlaps with the plane3101of the supporting pillar31. The pair of protrusions1902overlaps with the pair of protrusions3102of the supporting pillar31. The pair of protrusions1902each has an opening19aat a position overlapping with the opening31aformed in each protrusion3102of the supporting pillar31.

The fixing member191is provided as, for example, a plate spring having a protrusion1911. The fixing member191is adhered to the inner side of the protrusion1902of the supporting pillar support19at a position overlapping with the opening19a.

The protrusions1911of the fixing members191each protrude into the opening19aof the supporting pillar support19and then to the opening31aof the supporting pillar31, and hook on the protrusion3102of the supporting pillar31. By hooking the protrusions1911of the fixing members191on the protrusions3102of the supporting pillar31, the supporting pillar31is fixed (locked) to the supporting pillar support19.

When the supporting pillar31is rotated toward the base13side from the locked state illustrated inFIGS.14and15, the locked state of the supporting pillar31is released.FIG.16is a schematic diagram of the supporting pillar31and the supporting pillar support19when the locked state of the supporting pillar31illustrated inFIG.15is released.

When the supporting pillar31is rotated toward the base13from the state illustrated inFIG.14, the position of the supporting pillar31moves in the X-axis direction, and the positions of the openings31aof the supporting pillar31shift in the X-axis direction. Accordingly, the fixing members191are flexed when the fixing members191contact the protrusions3102of the supporting pillar31, and the protrusions1911are pushed into the openings19aof the supporting pillar support19. As a result, the locked state of the supporting pillar31is released.

The fixing members191are not limited to the plate spring having the integrated protrusions1911, but may be made of an elastic member different from the plate spring.
