Description

The present invention relates to support devices and stand displays.

Conventionally, a device, such as an electronic information board, has been used that accepts an operation to draw on display contents. Such devices often include a display device for displaying information and a support device for supporting the display device. The support device supports the display device at a height that facilitates drawing operations on the display device.

A device, such as the electronic information board described above, may be configured to be portable. In this case, for example, the support device is configured to support the display device in a low position during transport and raised to a predetermined height during use. Furthermore, in this case, a handle is often provided to facilitate transportation, and the handle of the device as described above is often provided so as to protrude above the display device ( For example, Patent Document 1).

However, if the handle is provided on the display device, the handle will be positioned above the display device that has been raised to a predetermined height during use. This is not desirable because the presence of the handle, which is unnecessary when using the electronic information board, increases the overall height. In addition, since the handle is always visible above the display device, it seems as if it is supposed to be carried by holding the handle even when the display device is raised to a high position. put away.

The brackets 21 are an example of a first member, and are attached to both ends of the display device 10 in the width direction. The rail 22 guides the bracket 21 movably between a storage position (lowest position) and a use position (highest position). Thereby, the display device 10 integrated with the bracket 21 is movable between the storage position and the use position by the rails 22 .

The foot 23 holds one end of the rail 22 to keep the rail 22 in a predetermined orientation. More specifically, the leg portion 23 holds the lower end portion of the rail 22 in a predetermined orientation in which the heights of one end portion and the other end portion of the rail 22 are different. The rail 22 of this embodiment has its longitudinal direction along an oblique direction that is slightly inclined from the vertical. The leg portion 23 has its longitudinal direction along the substantially horizontal direction. Also, the pair of legs 23 are arranged so that their longitudinal directions are parallel to each other.

The support device 20 has four casters 24 in total. The casters 24 are for facilitating transportation of the display device 10 (stand display 100). Casters 24 are small wheels attached to both ends of each leg 23 . Due to this arrangement, the imaginary line connecting the adjacent casters 24 draws a square. That is, the casters 24 are arranged at least at the four corners of the plane surrounded by the foot portion 23 .

The handle 25 is used as a handle when carrying the display device 10 and is arranged with its longitudinal direction along the width direction of the display device 10 . The handle 25 is positioned above the upper edge of the display device 10 when the display device 10 is in the storage position, and is positioned behind the screen 11 of the display device 10 when the display device 10 is in the use position. do.

The link part 26 is configured with a plurality of joints, and when a certain part (joint) is operated, the other parts are also operated in conjunction with each other. More specifically, when the display device 10 integrated with the bracket 21 is moved from the use position side to the storage position side, the link portion 26 is moved to the lower end portion (one end portion) by the lower edge portion of the display device 10 . When is pressed, the upper end (the other end) pushes the handle 25 toward the screen 11 of the display device 10 .

The cover 27 covers the lower end (one end) of the link portion 26 . The cover 27 has a groove 28 that receives the lower edge 13 of the display device 10 within the cover 27 . The lower edge portion of the display device 10 received in the cover 27 through the groove 28 presses the lower end portion of the link portion 26 .

The structure and operation of link portion 26 will be described in more detail. FIG. 5 is a side view showing the handle 25 and the link portion 26 with the support device 20 supporting the display device 10 at the use position.
