  FIG. 1 shows a display device according to an embodiment of the present invention. A link structure 10 includes first to sixth beam members 11, 12, 13, 14, 15 and 16 are combined in a link shape, and end portions thereof are rotatably pin-coupled by a well-known pin coupling structure to form a desired shape.

  That is, the first beam member 11 has, for example, four pairs of two as one pair, one end of which is pivotally connected to a pin, and each other end is provided with a floor mounting fixing portion 111. Installed. Two pairs of the first beam members 11 are arranged so as to face each other at a predetermined interval. A second beam member 12 is installed between one end of each pair, and the end portion of the first beam member 11 can be freely rotated. Combined to form a four-legged leg.

  And, between the two sets of the first beam member 11 that is a set of two, the third beam member 13 is bridged between the other end and the other end of the other, Each end portion is rotatably connected to a pin. In addition, one end of the fourth beam member 14 is pivotally connected to the other end of each of the two sets of first beam members 11, and the other end of the fourth beam member 14 is connected to each other end of the fourth beam member 14. The one end of the fifth beam member 15 is pin-coupled so as to be rotatable.

  One end of a sixth beam member 16 constituting a display mounting portion is pin-coupled to each other end of the fifth beam member 15 so as to be rotatable. The other end of the sixth beam member 16 is pivotally connected to one end of the first beam member 11 so as to be rotatable.

  The second beam member 12 is erected between the ends of the two sixth beam members 16 and between the pin connections at one end of the fifth beam member 15 so that the ends are connected to each other. It is pin-coupled so that it can rotate freely. Among these, between the both ends of two 4th beam members 14, the said 3rd beam member 13 is hung on what is called a hook, and each edge part is pin-coupled so that rotation is possible.

  Further, between each one end of the two sets of the first beam members 11 and the other end of the two fourth beam members 14, stretch members 17 constituting a stretch mechanism are respectively constructed in a link shape. The both ends are pin-coupled so as to be rotatable (see FIG. 2). When the telescopic member 17 is formed of a jack or the like and is selectively telescopically driven, the link connecting portions of the first, second, fourth, fifth and sixth beam members 11, 12, 14, 15, 16 are used. Is rotated to change the posture of the link structure 10.

  The space formed by the two sixth beam members 16 and the two second beam members 12 constitutes a display mounting portion, and the display 18 is mounted using this space. . The indicator 18 is connected by wiring to a controller 19 assembled between the fourth beam members 14 of the link structure 10, for example.

  The wiring connection between the display 18 and the controller 19 is performed using, for example, a gap between the beam members of the link structure 10 that is mounted and arranged. The indicator 18 and the controller 19 use the gap between the beam members of the link structure 10 when, for example, it is necessary to perform maintenance and inspection after the mounting arrangement on the link structure 10. Done.

  Further, on the other side of the two sets of first beam members 11, for example, first and second attachment portions 112 and 113 are provided at predetermined intervals corresponding to the spaces constituting the display attachment portion. . The attachment member 21 of the operation unit 20 is selectively attached to the first and second attachment portions 112 and 113.

  That is, when the attachment member 21 is attached to the first attachment part 112 of the first beam member 11, the operation part 20 is folded and accommodated so as to be folded on the display 18 attached to the space. Then, when the attachment member 21 is attached to the second attachment portion 113 of the first beam member 11, the operation portion 20 is unfolded and operably arranged on the display 19.

  In the above description, for convenience of explanation, the case where the controller 19 is configured to be assembled in the link structure 10 is representatively described. However, other electronic units and the like are assembled and arranged. May be.

  In the above-described configuration, the link structure 10 has the four first beam members 11 on which the floor surface fixing portions 111 are placed on the floor surface of an aircraft, for example, using screws or the like (not shown). It is fixed and arranged. In this state, when the expansion / contraction member 17 is driven to expand and contract and the link structure 10 is expanded as shown in FIG. 3 from the position shown in FIG. 2, for example, the first, second, fourth, fifth and sixth beam members 11, 12, 14, 15, and 16 are connected to the space formed by the second beam material 12 and the sixth beam material 16 by rotating the pin coupling portions 11, 12, 14, 15, and 16. The viewing angle is variable.

  When the elastic member 17 is inverted and contracted as shown in FIG. 4, the link structure 10 has the first, second, fourth, fifth and sixth beam members 11, 12, 14, 15, 16. These pin coupling portions are inverted, and the posture of the indicator 18 attached to the space formed by the second beam material 12 and the sixth beam material 16 becomes downward, and the viewing angle is variable. In this way, the link structure 10 is used by selectively adjusting the viewing angle of the display 18 by driving the telescopic member 17 to extend and contract in response to the operator.

  Further, the operation unit 20 is set so that the mounting member 21 is moved from the first mounting unit 112 to the second mounting unit 113 and is unfolded from the folding position, and is arranged on the display unit 18 so as to be operated. . For example, when the display unit 18 is not used, the operation unit 20 moves the first beam of the link structure 10 when the mounting member 21 is moved from the second mounting unit 113 to the first mounting unit 112. Folding along the material 11 enables effective use of the installation space.

  For example, when the operator changes and the viewing angle of the display 18 is changed to an optimum posture that matches the operator, the first, second, and second members of the link structure 10 are expanded when the telescopic member 17 is expanded and contracted. The link connecting portions of the beam members 11, 12, 14, 15, 16 of 4, 5, and 6 are rotated to change the posture, and the viewing angle of the display 18 is adjusted.

  As described above, the display device combines the first to sixth beam members 11, 12, 13, 14, 15, and 16 in a link shape, and the end portions are pivotally connected to each other to have a desired shape. The link structure 10 is formed, the indicator 18 is attached between the beams, and a floor surface fixing portion 111 is provided at the end of the first beam member 11 constituting the leg portion. The telescopic member 17 is installed between the pin coupling portions corresponding to the display unit 18 attached to the display unit 18, and the telescopic drive of the telescopic member 17 can change the posture of the display unit 18 to adjust the viewing angle. It was configured as follows.

  According to this, when the floor surface installation fixing portion 111 constituting the leg portion of the link structure 10 is attached to the floor surface, the first to sixth beam members 11, 12, 13, 14, 15 and 16 basically receive a load as an axial force, and when the expansion / contraction member 17 is driven to expand and contract, the first, second, fourth, fifth and sixth beam members 11 and 12 correspond to the expansion / contraction position. , 14, 14, and 16 are rotated to change the postures, and the supported display 18 is variably set to a desired posture.

  As a result, it is possible to obtain desired strength and rigidity while ensuring weight reduction, and also to easily realize variable adjustment of the orientation of the held display 18, thereby diversifying the visual form. Therefore, the usability can be improved.

  In the above-described embodiment, the case where the present invention is applied to the link structure 10 in which one display is attached and disposed has been described. However, the present invention is not limited to this. For example, as shown in FIG. It is also possible to configure a link structure 30 that is arranged in parallel with the device 18 so that the second display device 22 is independently arranged for posture adjustment, and the same effective effect is expected. However, in FIG. 5, the same parts as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, in this embodiment, the seventh indicator constituting the second indicator attachment portion with respect to the pin coupling portion of the fifth beam member 15 and the sixth beam member 16 constituting the indicator attachment portion. One end of the beam member 23 is rotatably pin-coupled, and the second beam member 12 is installed between the other ends of the two seventh beam members 23 so that the end portion is freely rotatable. Combined. The second indicator 22 is attached to a space surrounded by the two seventh beam members 23 and the second beam member 17. Here, the second indicator 22 is arranged in parallel above the indicator 18.

  In addition, a second elastic member 24 that can be extended and retracted is installed between the other ends of the two seventh beam members 23 and one end of the first beam member 11, and the end portion thereof rotates. Pin-coupled freely.

The posture of the second indicator 22 attached to is variably set.

  When the elastic member 17 is extended and contracted from the position shown in FIG. 6 as shown in FIGS. 7 and 8, the second elastic member 24 maintains the posture of the indicator 18 attached to the indicator attaching portion. In this state, the facing angle of the second indicator 22 attached to the second indicator attachment portion with respect to the indicator 18 is varied. That is, for example, in the expansion / contraction position where the expansion / contraction member 17 is expanded / contracted, the second expansion / contraction member 24 rotates the second display 22 by the expansion / contraction drive, thereby changing the facing angle with respect to the display 18. Set.

  For example, in the state in which the expansion / contraction member 17 is extended as shown in FIG. 8, when the second expansion / contraction member 24 is driven to expand / contract, the second display unit for the display unit 18 according to the expansion / contraction position. The facing angle of 22 is made wider as shown in FIG. 9 or made smaller as shown in FIG.

  When the second elastic member 24 is driven to extend and contract in a state where the elastic member 17 is contracted as shown in FIG. 7, the second elastic member 24 with respect to the indicator 18 is driven according to the expansion / contraction position. The facing angle of 24 is made wider as shown in FIG. 11 or made smaller as shown in FIG.

  As described above, the link structure 30 selectively drives the telescopic member 17 and the second telescopic member 24 to expand and contract, so that the viewing angle of each of the two units of the display unit 18 and the second display unit 22 can be set as desired. The value can be variably set. As a result, the two of the display 18 and the second display 22 can be adjusted to desired postures according to the body shape of the operator (user), and easy use can be realized. it can.
