Description

Embodiments of the present invention relate to display devices.

In recent years, a display device has come to be connected to a base on which the display device is mounted by a support structure conforming to a predetermined standard such as a VESA mount (VESA (Video Electronics Standards Association) mount). ing. The structure according to a predetermined standard provides versatility at the connection portion between the display device and the base. This makes it easier to replace and reuse the display device, and it has become widespread because it can be expected to have the effect of reducing costs.

In addition, there are display devices conventionally used for kiosk terminal devices and the like. The display device of the kiosk terminal device is provided with a touch panel on the surface, guides various information to the user at a store, etc., and accepts operations according to the display contents.

VESA mounts are also being used to connect the main body (corresponding to the base) of such a kiosk terminal device to the display device. There are a plurality of types of VESA mounts with different dimensions, and the size and weight range of the display device are defined for each type.

However, the VESA mount is a standard that defines the display device so that it can be supported in terms of size and weight, and does not consider the load when the display device accepts an operation. Further, since the VESA mount connects the central portion on the back side of the display device to the base portion, even if the central portion of the display device is operated, the area near the outer periphery of the display device is operated. In some cases, there is a risk of elastic deformation or plastic deformation.

Especially in the case of a kiosk terminal device, it is inconvenient if the components of the device are distorted or there is a gap because an unspecified number of users are the users.

An object to be solved by the present invention is to prevent displacement and deformation of a display device having a structure mainly conforming to a predetermined standard for connection with the base with respect to the base.

The display device of the embodiment includes a display unit, an operation unit, a housing, a main support unit, and a plurality of auxiliary support units. The display unit displays information on its surface. The operation unit is provided so as to cover the surface of the display unit, and accepts operations according to the position touched by the operator and the display content of the display unit at the position. The housing surrounds at least the periphery of the display unit and the operation unit and the back surface side of the display unit. The main support portion has a structure conforming to a predetermined standard, and supports the central portion on the back surface side of the housing in a fixed position with respect to the predetermined base portion. The plurality of auxiliary support portions support the outer peripheral portion, which is the back surface side of the housing and is outside the region fixed to the main support portion, with respect to the base portion. Further, the auxiliary support portion has one end portion detachably attached to the base portion and the other end portion touches the housing, and the other end portion has a slope inclined with respect to the base portion. The slope is brought into contact with the housing, and the one end portion has an elongated hole provided along the direction from the central portion to the outer peripheral portion in the longitudinal direction, and the base portion is described as described above. The position can be adjusted in the longitudinal direction of the elongated hole.

(First Embodiment)
The embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of the display device 1 according to the present embodiment. The display device 1 includes a display unit 2, an operation unit 3, a housing 4, a main support unit 5, and an auxiliary support unit 6. What is indicated by reference numeral 7 is a base. The base 7 is a part of the main body. The main body is, for example, the main body of the kiosk terminal device, excluding the display device 1 provided at the top of the kiosk terminal device. Further, when the main body portion is a kiosk terminal device, the base portion 7 is generally in the shape of a slope inclined to some extent. In the drawing, the base 7 is shown upward, but in practice, the orientation of the base 7 does not matter.

The display device 1 is provided at the top of the kiosk terminal device, for example, and receives various operations according to the display contents from a user (operator) such as a customer of a store in which the kiosk terminal device is provided.

FIG. 2 is a side view showing the internal structure of the display device 1 and the support structure of the auxiliary support portion 6. The display unit 2 is a display device such as a liquid crystal panel, and displays information directed to the user on the surface thereof. The operation unit 3 is provided so as to cover the surface of the display unit 2. In other words, the operation unit 3 is provided so as to be laminated on the display unit 2. The operation unit 3 is an operation device such as a touch panel, and receives an operation according to a position touched by the operator and the display content of the display unit 2 at the position.

The housing 4 has an outer peripheral portion 41 that surrounds the operation unit 3 and the display unit 2, and a back surface portion 42 that covers the back surface of the display unit 2. The back surface portion 42 forms a space S with its own inner surface and the back surface of the display unit 2. A board or the like that controls the display unit 2 and the operation unit 3 is housed in the space S.

The housing 4, the display unit 2, and the operation unit 3 have a substantially rectangular shape when viewed from a position facing the display surface of the display unit 2. Further, the back surface portion 42 of the housing 4 is formed in a rounded shape.

The main support portion 5 and the auxiliary support portion 6 are arranged between the back surface portion 42 and the base portion 7 of the housing 4, and support the display device 1 in a fixed position with respect to the base portion 7.

The main support portion 5 has a structure conforming to a predetermined standard. As a predetermined standard, for example, there is a VESA mount. In this embodiment, a case where a VESA mount is adopted as a predetermined standard will be described as an example. Further, in the present embodiment, the case where the size of the display unit 2 is 17 to 21 inches will be described as an example. The details defined by the VESA mount will be omitted.

In the present embodiment, since the size of the display unit 2 is 17 to 21 inches, the main support unit 5 conforms to the above standard and is 75 or 100 mm square in a plan view (when looking down from the upper part in the figure). It has a square shape and is screwed to the four corners of the square. With such dimensions, the ratio of the vertical or horizontal lengths of the display device 1 and the main support portion 5 becomes close to 2: 1 or 3: 1 in a plan view. In other words, the main support portion 5 has a size of about 1/3 to 1/2 of that of the display device 1. That is, it can be said that the main support portion 5 is attached to the central portion of the display unit 2, the operation unit 3, and the housing 4 to support these (display unit 2, the operation unit 3, and the housing 4). Therefore, if the display device 1 does not have the auxiliary support portion 6 and has a structure in which the display unit 2, the operation unit 3, and the housing 4 are supported only by the main support portion 5, the back surface portion 42 of the housing 4 is supported. The load applied to the outside (outer peripheral portion) of the central portion (including the first region where the main support portion 5 is fixed) becomes the moment around the main support portion 5.

Here, the background is supplemented. In recent years, the size of the above-mentioned board has been reduced due to the improvement of technology, and the board, which was previously close in size to the display unit 2 and the operation unit 3, is displayed as being smaller than, for example, half of the display unit 2 and the operation unit 3. It has become considerably smaller than the unit 2 and the operation unit 3. For this reason, the display device 1 is no longer able to obtain the rigidity derived from the substrate, which has been expected in the past. As a result, it has become difficult for the display device 1 to withstand the load applied to the operation unit 3 (particularly the outer peripheral portion) by supporting only the main support portion 5.

Therefore, the display device 1 of the present embodiment is provided with a plurality of auxiliary support portions 6 in order to withstand the load typified by the above-mentioned moment. The auxiliary support portion 6 supports the outer peripheral portion of the back surface portion 42 with respect to the base portion 7. As described above, the outer peripheral portion is the outside of the central portion including the first region fixed to the main support portion 5.

In the present embodiment, the display device 1 has four auxiliary support portions 6, which are provided between the four corners or the vicinity of the four corners of the substantially rectangular housing 4 and the base portion 7. The above-mentioned "four corners or the vicinity of the four corners" is preferably a predetermined region (second region) including the diagonal line of the housing 4 in the above-mentioned outer peripheral portion.

FIG. 3 is a perspective view showing a support structure of the auxiliary support portion 6. The auxiliary support portion 6 includes a strut sheet metal 61, a pedestal portion 62, and a screw 63. The pedestal portion 62 is fixed by being attached to the base portion 7 or the like.

The support sheet metal 61 has three portions formed by, for example, bending the sheet metal, and has a first portion (an example of one end portion) 611, a second portion 612, and a third portion (the other end portion). One example) 613. The first part 611 and the second part 612 are continuous and form a right angle between them. The second part 612 and the third part 613 are continuous and form an obtuse angle between them.

FIG. 4 is a perspective view showing the appearance of the support column sheet metal 61. The first portion 611 is placed on the pedestal portion 62 in a laminated state, and is fixed to the pedestal portion 62 and the base portion 7 by screws 63. The second portion 612 is a portion that rises away from the first portion 611 and the base 7 and reaches the third portion 613. The third portion 613 has a slope 613a and a tip portion 613b that are inclined with respect to the base 7. The support sheet metal 61 is in contact with the housing 4 by the slope 613a or the tip portion 613b, and supports the housing 4, the display unit 2, and the operation unit 3.

The strut sheet metal 61 has a pair of elongated holes 614,615. In the elongated holes 614 and 615, the holes 614a and 615a provided in the first portion 611 and the holes 614b and 615b provided in the second portion 612 are continuous.

The screw 63 is screwed into the pedestal portion 62 through the holes 614a and 615a, leaving the head 63a on the first portion 611. As a result, the column sheet metal 61 is fixed to the base 7.

Here, in the present embodiment, the longitudinal directions of the holes 614a and 615a are substantially along the direction from the central portion to the outer peripheral portion of the housing 4. As a result, the column sheet metal 61 can be displaced with respect to the pedestal portion 62 along the longitudinal direction of the holes 614a and 615a. The displacement facilitates the positioning of the auxiliary support portion 6 for appropriately supporting the rounded housing 4 as in the present embodiment.

In the display device 1 having such a configuration, as shown in FIG. 1, the main support portion 5 and the auxiliary support portion 6 support the housing 4, the display unit 2, and the operation unit 3. The main support portion 5 supports the central portion of the housing 4. The auxiliary support portion 6 supports the outer peripheral portion of the housing 4. The auxiliary support portion 6 also has one end thereof whose position can be adjusted in the second region with respect to the base portion 7, and the other end portion touches the housing 4.

When the operation unit 3 receives the operation of the user, the display device 1 receives the load, but the main support portion 5 in the central portion and the auxiliary support portion 6 in the outer peripheral portion cooperate to bear the load. As a result, it is possible to prevent the inconvenience that only the main support portion bears the load and is deformed as in the conventional case.

As described above, according to the present embodiment, the display device 1 whose structure mainly conforms to a predetermined standard (main support portion 5) is connected to the base portion 7 is prevented from being displaced or deformed with respect to the base portion 7. Can be done. As a result, factors that hinder the reuse and diversion of the display device 1 (deformation of the main support portion 5, etc.) can be prevented, and the life of the display device 1 can be expected to be extended.

Although the VESA mount has been described as an example of a predetermined standard in this embodiment, the present embodiment may be applied to other standards in practice.

Further, in the present embodiment, the auxiliary support portion 6 is specifically illustrated, but this is just an example, and the auxiliary support portion 6 has a base portion outside the first region fixed to the main support portion 5. It may have another shape that can be supported with respect to 7.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
