Description

The present invention relates to a movable stand device that supports a display panel such as an electronic monitor (display).

Electronic monitors are used in a variety of places. In particular, in recent years, with the progress of larger sizes, higher definition, and lower prices, opportunities for use in offices, stores, schools, various demonstration venues, etc. are increasing. The electronic monitor is then supported by a stand device.

As an example of a stand device for an electronic monitor, Patent Document 1 discloses a stand body having two upper and lower support beams on the left and right longitudinal sides, and a bracket fixed to the back of the electronic monitor. It is disclosed to provide upper and lower hook portions that fit into the beam.

On the other hand, since there are other types of electronic monitors with different sizes, there are many requests to arrange them at different heights, but in Patent Document 1, the height of the electronic monitor is kept constant. Therefore, there is a problem that it is difficult to meet this demand.

Regarding this point, Patent Document 2 discloses a configuration in which the height of the electronic monitor can be adjusted by providing a support column on the stand body that can be raised and lowered and a vertical support beam provided on the support column. Further, Patent Document 3 discloses a configuration in which the height of the electronic monitor can be adjusted by arranging the support beams of the stand main body in three stages and changing the locking height position of the bracket. .

Utility model registration No. 3193326 CD-ROM Japanese Patent Application Publication No. 2010-107746 Japanese Patent Application Publication No. 2005-108974 (Patent No. 4007952)

Although the configuration of Patent Document 2 allows the height of the electronic monitor to be changed, there is a problem that the structure becomes extremely complicated and the cost increases. On the other hand, since the structure of Patent Document 3 is simpler than that of Patent Document 2, an increase in cost can be suppressed, but there is a risk that the stand body becomes larger.

The present invention has been made against the background of this current situation, and it is an object of the present invention to disclose a stand device that can adjust the height of a display panel such as an electronic monitor without increasing the size or complicating the device.

The present invention relates to a stand device that supports a display panel in a height-adjustable manner, and this stand device includes:
"A stand body having left and right longitudinal support beams,
a vertically longitudinal first bracket fixed to the back surface of the display panel;
a second bracket that is height-adjustably fixed to the first bracket and attached to the support beam of the stand body.
The structure is as follows.

The present invention can be developed and embodied in various ways. As an example, the invention of claim 2 is:
“The support beams of the stand main body are arranged in multiple stages above and below,
The second bracket includes a hook-type bracket that fits onto one of the support beams from above, and a fixed bracket that is fixed to the front surface of the support beam at a different height from the one of the support beams with a fastener so that it cannot move up and down. It consists of a bracket and
The structure is as follows.

As a preferred specific example of the invention of claim 2, in claim 3,
"The hook-type bracket is arranged on the upper stage and the fixed bracket is arranged on the lower stage."
The structure is as follows.

The invention of claim 4 is based on any one of claims 1 to 3,
"The first bracket is formed in a U-shape in plan view with left and right side plates, and the second bracket is disposed inside the first bracket."
The structure is as follows.

As a specific example of claim 4, claim 5:
"Mounting holes are formed in the left and right side plates of the first bracket in multiple stages above and below, and the hook-type bracket and the fixed bracket are fixed inside the first bracket by means of fasteners inserted into the mounting holes. It is retained.”
The structure is as follows.

The invention of claim 6 is, in claim 2 or 3,
"The support beam has a plurality of through holes arranged in the left and right direction for fixing the fixed bracket with fasteners."
The structure is as follows.

In the present invention, the height of the display panel is changed by replacing the second bracket with the first bracket, and since the bracket has a height adjustment function, it is necessary to perform special processing on the stand body. This prevents the stand from becoming larger. Further, the second bracket does not need to be large as long as it has the function of attaching to the second bracket and the support beam, so the overall size of the bracket does not increase. Therefore, the stand device of the present invention can support the display panel in a height-adjustable manner while suppressing the increase in size.

The structures of the first bracket and the second bracket can be embodied in various ways, but if the second bracket is composed of a hook type bracket and a fixed bracket as in claim 2, the hook type bracket can be locked to the support beam. Since the display panel can be held so that it cannot fall, the display panel can be installed and removed safely and easily.

If the second bracket is composed of a hook type bracket and a fixed bracket as in claim 2, when the hook type bracket is locked to the support beam, the display panel will not be able to use the hook type bracket as a fulcrum due to its own weight. However, if the hook type bracket is placed on the upper level and the fixed type bracket is placed on the lower level as in claim 3, the weight of the display panel will cause the fixed type bracket to come into close contact with the lower level support beam. Therefore, even if a person takes his/her hand off the display panel during installation/removal work, the display panel is maintained in a stable posture. Therefore, the work of attaching and detaching the display panel can be done safely and easily.

The relationship between the first bracket and the second bracket can be set in various ways, but if the first bracket is formed into a U-shaped groove and the second bracket is placed inside it, the entire bracket is Not only can it be made more compact, but it is also superior in terms of strength because the first bracket can be reinforced by the second bracket.

If claim 5 is adopted as a development example of claim 4, the strength of the first bracket will not basically decrease even if mounting holes are provided in the side plates of the first bracket, and on the contrary, the strength of the first bracket will not decrease even if the left and right side plates are connected to the second bracket. Since the first bracket is in a connected state, the rigidity and strength of the first bracket can be improved. Furthermore, although the substrate of the first bracket is fixed to the back surface of the display panel with screws or the like, there is an advantage that the function of fixing the first bracket to the display panel is not impaired.

Display panels such as electronic monitors come in various sizes, and the fixing position of the first bracket also differs depending on the size (particularly the left and right width). Since the attachment position to the support beam can be changed depending on the arrangement position, it has excellent adaptability to differences in display panel size. Therefore, it has high practical value.

It is a figure which shows embodiment, (A) is a perspective view seen from the front, (B) is a perspective view seen from the back. (A) is an isolated perspective view, and (B) is a perspective view of some members separated and seen from the rear lower side. (A) is an isolated perspective view of essential parts, and (B) is a sectional view taken along IIIB-IIIB of FIG. 1. FIG.

(1).Description of structure Next, embodiments of the present invention will be described based on the drawings. As shown in FIGS. 1 and 2, the stand device includes a stand main body 1 that stands free on the floor, left and right first brackets 3 fixed to the back surface of a display panel 2, and is connected to the upper part of the first bracket 3. It includes a hook-type bracket 4 (see FIG. 3), and a fixed bracket 5 (see FIG. 3) connected to a lower portion of the first bracket 3. The hook type bracket 4 and the fixed type bracket 5 constitute a second bracket described in the claims.

The stand main body 1 includes left and right legs 6 that have an inverted V-shaped posture when viewed from the side, pillars 7 that stand up from the left and right legs 6, and a reinforcing stay 8 that connects the left and right legs 6 at a mid-height. and two upper and lower support beams 9 mounted on left and right columns 7. Casters 10 are provided at the lower ends of the legs 6.

The leg portion 6 is made of a round pipe made of steel or the like, and one portion of the leg portion 6 is extended upward to form a support 7. The support beam 9 is formed hollow by a square pipe, and has a vertically long rectangular shape when viewed from the side.

Between the upper ends of the left and right legs 6, there are installed left and right long article trays 11 on which accessories such as writing instruments and pointers can be placed. As shown in FIG. 2(B), a reinforcing stay 12 made of a square pipe similar to the support beam 9 is connected between the upper ends of the left and right legs 6, and articles are mounted on the reinforcing stay 12 via left and right bracket pieces 12a. A storage tray 11 is fixed.

To be more precise about the leg portions 6, the reinforcing stays 12 are connected to the left and right leg members on which the pillars 7 stand up, and the upper ends of the other leg members are fixed to the left and right side portions of the reinforcing stays 12. Therefore, as clearly shown in FIG. 4, the leg members on which the pillars 7 stand are located on the left and right outer sides.

As clearly shown in FIG. 3, the first bracket 3 is made of steel and includes a substrate (back plate) 3a that overlaps the back surface of the display panel 2, and left and right side plates 3b. Therefore, it has a U-shaped channel shape (groove shape) that opens backward in plan view. Three stages of through-holes 13 are formed in each of the upper and lower parts of the substrate 3a, and the first bracket 3 is fixed to the back surface of the display panel 2 with screws 14 inserted into the through-holes 13. There is. Therefore, a tapped hole 15 into which a screw 14 is screwed is provided on the back side of the display panel 2.

On the other hand, the hook type bracket 4 has a U-shape in plan view having a base plate 4a and left and right side plates 4b, and has a left and right width that fits inside the first bracket 3. The protruding portion protrudes backward from the support beam 9, and the protruding portion forms a downward hook portion 16 that fits into the support beam 9 from above. That is, a notch that fits into the support beam 9 is formed in the side plate 4b to form a hook portion 16.

The left and right side plates 3b of the first bracket 3 have pairs of mounting holes 18 in three stages at the top and bottom, while the left and right side plates 4b of the hook type bracket 4 also have mounting holes 19, and the first bracket The hook-type bracket 4 is held in place by inserting it from the other side plate 3b of the first bracket 3 and screwing a screw 21 into the cylindrical nut 20 inserted through one side plate 3b of the first bracket 3. As shown in FIG. 3(A), the screw 21 is a stepped screw having a stepped portion 21a having the same diameter as the cylindrical nut 20. As shown in FIG.

As shown in FIG. 3(B), the board 4a of the hook type bracket 4 overlaps the board 3a of the first bracket 3, but the screws 14 that fix the first bracket 3 to the display panel 2 are connected to the hook type bracket 4. Since they may overlap, a downward notch 4d is formed at the lower end of the base plate 4a of the hook type bracket 4 to allow the head of the screw 14 to escape.

The fixed bracket 5 is U-shaped and has a substrate 5a and left and right side plates 5b, and is open toward the back plate 3a of the first bracket 3, and the substrate 5a overlaps the front surface of the support beam 9. . As with the hook-type bracket 4, mounting holes 22 are formed in the left and right side plates 5b, and like the hook-type bracket 4, it is connected to the first bracket 3 with a tube nut 20 and a screw 21.

The side plate 5b of the fixed bracket 5 is in contact with the base plate 3a of the first bracket 3, so that the fixed bracket 5 is connected to the first bracket 3 in a non-slip manner. The fixed bracket 5 is fixed to the lower support beam 9 by fixing a nut 23 to the inner surface of the substrate 5a and screwing into the nut 23 a screw 24 inserted through the lower support beam 9 from behind. Therefore, the lower support beam 9 has mounting holes 25 through which the screws 24 pass, and a plurality (four) of the mounting holes 25 are provided at intervals on the left and right sides.

(2).Summary In the above configuration, by changing the height of the hook type bracket 4 and the fixed type bracket 5 with respect to the first bracket 3, as indicated by the two-dot chain line and the three-dot chain line in Fig. 4, the display panel You can change the height of 2. Although this embodiment can accommodate, for example, a 75-inch electronic monitor, it is possible to improve the display effect by supporting a large electronic monitor in a state where it is most easily recognized.

Further, by changing the fixing position of the fixed bracket 5 to the lower support beam 9 to the left or right, the left-right position of the first bracket 3 can be changed. Therefore, it is possible to flexibly respond to differences in the left and right widths of the display panel 2. That is, the stand device of this embodiment can support display panels 2 of various sizes, and can also adjust the height of the display panel 2 in three levels. Therefore, it is highly flexible.

When attaching the display panel 2, the hook type bracket 4 is secured to the upper support beam 9, and then the fixed bracket 5 is fixed to the lower support beam 9. 9, the display panel 2 is held so that it cannot fall, so the operator can take his hand off the display panel 2 and fix the stationary bracket 5 to the lower support beam 9. Therefore, the installation work can be done safely and quickly.

Since the display panel 2 is placed in front of the support beam 9, the display panel 2 tries to rotate with its own weight using the hook type bracket 4 as a fulcrum so that its lower end points backward. Since the bracket 4 is engaged with the upper support beam 9, the display panel 2 is in close contact with the support beam 9. Therefore, the display panel 2 can be stably held.

As in the embodiment, when the hook type bracket 4 and the fixed type bracket 5 are fixed with a fastener consisting of a tube nut 20 and a stepped screw 21, the distance between the left and right side plates 3b of the first bracket 3 is maintained by the fastener, so that the left and right side plates 3b are fixed. Since the side plates 3b are connected by fasteners, the rigidity and strength of the first bracket 3 can be significantly improved, and the fixing strength of the hook type bracket 4 and the fixed type bracket 5 can also be improved.

Although the embodiments of the present invention have been described above, the present invention can be embodied in various other ways. For example, the second bracket may be configured to fit into the first bracket from the outside. Further, the first bracket may have a hollow rectangular shape or a C-shaped channel structure. Although the stand main body in the embodiment is made of a round pipe, it may also be made of a square pipe or an angle material.

In the embodiment, the second bracket is composed of a hook-type bracket and a fixed bracket that are vertically separated, but it is also possible to configure the second bracket to be vertically continuous. That is, it is also possible to form a configuration in which one second bracket is provided with a hook portion and a fixing portion. Expandable rivets (blind rivets) can also be used as the fasteners for fixing the second bracket to the first bracket and the fasteners for fixing the second bracket to the support beam.

The present invention can actually be applied to a stand device. Therefore, it can be used industrially.
