[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat table for an aircraft that can be stored in an armrest of a passenger seat of an aircraft or the like and can be appropriately taken out to the front of the seat for use.

[0002]

[Prior art]

 Conventionally, a passenger seat mounted on an aircraft is stored in a storage recess (not shown) of an armrest 51 of the seat when not in use as shown in FIG. 6, and taken out of the armrest 51 when used. A seat table 52 is constructed in such a manner that it is horizontally deployed and supported on the front surface of the seat. In this type of seat table, the table main body 53 is rotatably supported in the front-rear and left-right directions via a hinge mechanism 54 at the front end opening edge of a storage recess that is configured to open on the upper surface of the armrest 51. At the same time, it can be used by being horizontally deployed on the front surface of the seat (along line H in the figure), that is, in a state of being flatly deployed and supported on the floor surface of the aircraft.

[0003]

[Problems to be solved by the device]

 However, since the flight angle of the aircraft is in a normal flight state, the aircraft is in a posture (along line F in the figure) inclined at a forward rising angle α of about 2 to 3 degrees with respect to the horizon with respect to the ground surface. As described above, the table main body 53, which is supported in a horizontal (H line) state with respect to the floor of the aircraft, is supported in a posture in which the table main body 53 is inclined forward and backward by about a few degrees with respect to the horizontal line H. . Therefore, a drink, tableware, or pen placed on the table main body 53 inclined forward and upward as described above easily slides on the table main body 53, and in the worst case, the drink, tableware, or the like falls, There was a problem such as dropping from the table body 53.

The aircraft seat table according to the present invention was conceived in view of the above problems, and drinks and tableware placed on the table body even in an aircraft that is flying in a posture inclined forward and upward. It is an object of the present invention to provide an aircraft seat table configured so as to horizontally support the above.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, an aircraft seat table according to the present invention is a hinge mechanism in which one end side of an opening edge of a storage recess formed in an arm rest is rotatable in the front-rear vertical direction and the left-right upward and downward directions. The table arm is attached to the other end side of the table body, and when not in use, the table body is stored in the storage recess, and if necessary, it is taken out to the front of the seat and placed horizontally in the use position. The gist of the present invention is that, in a seat table that is used while being supported by the above, the table body is configured to be extended forward and downward at the use position. The table arm fixed to the armrest via the hinge mechanism is configured such that one end side of the table arm has a twisted shape in the vicinity of the hinge portion, or a table arm hinge mechanism for deploying the table body in the left-right and up-down directions. The table main body attached to the other end side can be configured to be extended forward and downward in the use position. Further, a slide rail is fixed to the lower surface of the table body, and a spacer is interposed between the slide rail and a sliding engagement member on the side of the table arm that slides on the slide rail. It can also be configured to support deployment. Further, the amount of protrusion of the spacer above can be adjusted appropriately.

[0006]

[Action]

 According to the above configuration, the table main body deployed in the use position is supported in the front lowering attitude corresponding to the forward rising attitude of the aircraft, so that the table main body is supported parallel to the horizontal line and the table main body is used in the horizontal attitude. be able to. Thus, even during flight, drinks, dishes, etc. placed on the table body are not tilted or overturned, or dropped from the table body.

【Example】

 An embodiment of an aircraft seat table according to the present invention will be described below with reference to the drawings. FIG. 1 shows a two-seat seat that constitutes an aircraft seat table according to the present invention. In the drawings, reference numeral 1 is a table body according to the present invention. When not in use, the table body 1 is housed in a storage recess (not shown) of an armrest 3 formed on both left and right sides of a seat 2 and the armrest 3 The structure is such that the storage recess is covered by an arm cushion 4 that also serves as a lid that is openably and closably attached to the upper edge of the table. When using, the arm cushion 4 is opened and the table body 1 is attached to the armrest 3 The structure is such that it can be taken out above the car and unfolded in front of the passengers.

FIG. 2 is an enlarged plan view of the aircraft seat table. In the table body 1 according to this embodiment, two table plates 1a and 1b are foldably connected to each other by connecting means 5 and 5 having hinge equality, and both table plates 1a and 1b are developed on the front surface of the seat 2. In this state, it is configured so as to have a horizontally elongated, substantially rectangular shape, and the one side table plate 1a can be folded over the other side table plate 1b at the connecting portion of the two table plates 1a and 1b. I am doing it. In addition, a relatively large surface is cut out on the front side (passenger side) of the outer ends of the table plates 1a and 1b, so that when the table body 1 is horizontally rotated, the table body 1 is cut off. The corners of the table are designed so as not to interfere with the armrests 3, etc., and even if the table body 1 rotates around the corners and collides with the walls of the machine body, etc., they will be damaged or damaged. The structure is such that it is covered with a leather or rubber strap 6 so that it will not occur.

Reference numeral 7 is a table arm that horizontally supports the table body 1 during use. The table arm 7 has a structure in which it is axially attached to the front edge of the opening of a storage recess (not shown) formed in the arm rest 3 via a hinge mechanism 8 formed at one end thereof. It is configured to freely rotate in the left-right and up-down directions by the shaft support portion 8a and in the front-rear and up-down directions by the shaft support portion 8b.

On the other end of the table arm 7, a rectangular flat plate-shaped turntable 9 is attached so as to be rotatable forward and backward about an axis 10 perpendicular to the table arm 7. Within a range in which the plurality of protrusions 11, 11 ... Protrudingly provided on the surface are fitted into the plurality of arcuate guide grooves 12, 12 ... Perforated around the shaft 10 on the table arm 7 side and sliding is restricted. The rotating plate 9 can be rotated by. Further, two slide rails 13, 13 are fixedly mounted on the lower surface of the table body 1 so as to face the front-back direction at the use position of the table body 1, and the slide plate 13 is mounted on the upper surface of the rotary plate 9 so as to face the slide. Sliding engagement members 14, 14 which correspond to the rails 13, 13 and are slidably fitted to the rails 13, 13 are formed, and the both are slidably fitted so that the table body 1 is placed on the table arm 7. It is configured so that the use position can be changed by freely sliding in the front-back direction. On one end side of the table arm 7 configured as described above, an appropriate portion on the side of the hinge mechanism section 8 is formed in a twisted shape in the vicinity of the hinge section, and the table main body 1 attached to the other end side is in a use position. It is constructed so that it can be unfolded and supported forward (see Fig. 3). Therefore, the table body 1 can be supported in a horizontal posture even when the aircraft is in a forward-lying posture during flight, and drinks, dishes, and the like placed on the table body 1 can be inclined or fall down. Absent. In this embodiment, the table arm 7 is formed in a twisted shape so that the table body 1 is supported downward in the use position. The same effect can be obtained even if the pivotal support portion 8a of the hinge mechanism 8 is configured to be supported downward.

4 and 5 show another embodiment of the seat table according to the present invention. FIG. 4 is an enlarged sectional view showing a fitted state of the sliding engagement member 14 with respect to the slide rail 13. FIG. 5 is a partial side view. Between the fixed portions of the slide engagement member 14 with respect to the slide rail 13, a spacer 15 for improving the slippage between the two is normally interposed. In this embodiment, the support height of the table body 1 with respect to the rotating plate 9 is changed by adjusting the thickness of the spacer 15 interposed between the fixed portions of the slide rail 13 and the sliding engagement member 14. It was done. That is, the spacer 15 is wound around the bolt 17 through which the hole 16 formed in the rotary plate 9 is inserted from the lower surface side of the rotary base 9 in order to fix the sliding engagement member 14 on the rotary plate 9. The stepped nut 18 is screwed onto the head of the bolt 17 protruding above the sliding engagement member 14, and the sliding engagement member 14 is provided between the stepped portion 18a of the nut 18 and the upper surface of the rotary plate 9. The structure is such that tightening is integrated (see Fig. 4).

In the present embodiment, the sliding engagement members 14 are respectively formed in front and rear two places (total four places) with respect to the two left and right slide rails 13. Therefore, the thickness of the slide engagement members 14 is set to the table arm 7. The fixed table body 1 is supported on the front lower side by increasing the thickness of the spacer 15 interposed between the sliding engagement members 14 on the front side when the fixed table body 1 is deployed on the front surface of the seat. You can do it. Further, the thickness of the spacer 14 may be formed thicker from the beginning, and a plurality of spacers 15 having the same thickness may be overlapped to adjust the difference in height between the front and the rear. In the illustrated example, one spacer 15 is provided on the front side and three spacers 15 are provided on the front side so that the table main body 1 is supported in the front downward direction (see FIG. 5).

As described above, since the supporting height of the table body 1 can be adjusted by changing the number of the spacers 15 wound around the front and rear sliding engagement members 14, 14, the conventional seat table can be used. In contrast, the present invention can be easily implemented. Further, not only the number of spacers 15 can be changed, but also the inclination angle of the table body 1 can be adjusted by changing the amount of protrusion of the bolt 17 around which the spacer 15 is wound.

[0014]

[Effect of device]

 Since the aircraft seat table according to the present invention is configured as described above, in the position where the table is used, the unfolded table body is maintained in the front-lowering posture with respect to the armrest, and the airplane is kept in the front-up state. Even inside, the table can be kept horizontal. Therefore, drinks, meals and the like placed on the table body do not tilt and the pen and the like do not roll down, so that the seat table can be used in a comfortable state.

In addition, when the spacer is used, there is a feature that it can be applied to a conventional seat table, and a subtle inclination angle can be adjusted. Extremely large.
