The memo table 1 is provided with an openable / closable lid 6 in an opening 5 of the memo table housing 3 into which the memo table main body 2 enters and exits. Has an open lock mechanism 7 for locking the open state. For this reason, when the memo table main body 2 is out of the memo table storage unit 3, the lid 6 is locked in an open state by the release lock mechanism 7. Therefore, the lid 6 can be prevented from closing when the memo table main body 2 is used, so that the memo table main body 2 can be easily stored without hitting the lid 6 when the memo table main body 2 is stored in the memo table storage section 3. Thus, for example, when a seated person flips up the memo table main body 2 in an emergency, the memo table main body 2 is stored as it is and does not hinder the passage.

As shown in FIGS. 1 to 4, the release lock mechanism 7 is provided in the memo table receiving portion 3 so as to slide as the memo table main body 2 moves in and out, and opens the lid 6 by sliding. A lock lever 8 that can be positioned at the open position O to be maintained and a fixing means 9 that fixes the lock lever 8 to the open position O when the memo table main body 2 is out of the memo table storage unit 3 are provided. For this reason, the memo table main body 2 is
As the fixing means 9 locks the lock lever 8 at the open position O, the lid 6 can be kept open.

On the other hand, the memo table 1 has a closing mechanism 10 for urging the cover 6 to be closed when the memo table main body 2 is stored in the memo table housing section 3. For this reason, when the memo table main body 2 is accommodated in the memo table accommodating section 3, the cover 6 is urged by the closing mechanism 10 to close.
Therefore, since the cover 6 is automatically closed by storing the memo table main body 2 in the memo table storage section 3, it is possible to prevent the lid 6 from being obstructed with the lid 6 being opened after the memo table main body 2 is stored. Thereby, for example, in the event of an emergency, the seated person
The cover 6 does not hinder the passage when the is lifted up and stored as it is.

The closing mechanism 10 is connected to the lid 6 and is provided with a lock lever 8 provided on the memo table housing 3 so as to slide as the lid 6 opens and closes. Displacement means 11 provided between the memo table main body 2 and the lock lever 8 is slid in the direction in which the lid 6 is closed when the memo table main body 2 is stored in the memo table storage section 3. Therefore, when the memo table main body 2 is accommodated in the memo table accommodating section 3, the displacement means 11 can slide the lock lever 8 via the memo table support section 4 to close the lid 6.

The chair 12 has supports 13, 13 provided on the left and right sides, a backrest 14 provided between the rear portions of the supports 13, and a vertical support between the lower portions of the supports 13. And a seat 15 provided to be swingable.

The memo table 1 is provided on one of the supports 13. The support 13 has a pair of side plates 16, 17 of an inner plate 16 located inside the chair 12 and an outer plate 17 located outside the chair 12 arranged at a predetermined interval in parallel, and at least between them. A hollow portion S that opens forward and upward is formed. At the upper end of each side plate 16, 17, the armrest main body 1 is closed so as to close the opening above the support 13.

The hinge 19 is provided with a torsion coil spring (not shown) that urges the lid 6 in the opening direction. Therefore, even if the lock lever 8 is not located rearward, the opening of the lid 6 can be maintained. The torsion coil spring is set to such a strength that the lid 6 cannot be opened due to the weight of the memo table main body 2 and the memo table support 4 when the memo table main body 2 is at the accommodation position P. Further, a spring for pushing the lock lever 8 forward may be provided as necessary.

As shown in FIGS. 4 to 6, a memo table support portion 4 for supporting the memo table main body 2 so as to be able to protrude and retract is provided with a memo table support arm 20 for rotatably supporting the memo table main body 2, An auxiliary arm 21 that operates in conjunction with the arm 20;
A linear guide arm 22 for controlling the behavior of the memo support arm 20 via the auxiliary arm 21;
And a damper 23 for buffering the swing of the second. However,
The damper 23 is not necessarily required.

The rear end of the memo table support arm 20 is rotatably screwed to the outer plate 17 by a support shaft 24 composed of bolts extending in the left and right directions. Disc-shaped spacers 25 are provided on both side surfaces of the rear end. A comb-shaped hinge 26 is formed at the front end of the memo support arm 20. And the memo table support arm 20
Is rotated about the rear end, so that the hinge portion 26 projects forward from the hollow portion S of the memo support 4 (shown in FIG. 3) and the hinge portion 26 fits in the hollow portion S (FIG. 1). Shown)
And move on.

The memo table main body 2 is attached to the memo table support arm 20 via a bracket 27. The bracket 27 has a fastening surface 28 for fastening the memo stand main body 2.
And a comb-shaped hinge portion 29 that meshes with the hinge portion 26 of the memo table support arm 20. The hinge portion 26 of the memo support arm 20 and the hinge portion 29 of the bracket 27 are meshed with each other, and the rotation pin 30 is inserted so as to be swingably connected in a hinge shape. Furthermore, each hinge part 26,
When the memo table support arm 20 is protruded forward, the rotating pin 30 faces forward and backward, and the bracket 27
And the memo table main body 2 is in the vertical state (shown in FIG. 3).
And a horizontal state inside the chair 12 (shown by a solid line in FIG. 2)
It is formed so that it can swing only between

In the present embodiment, the memo table main body 2 takes a vertical position and is connected to the memo table main body 2 via the memo table support arm 20.
The position (shown in FIG. 6) where is stored in the memo table housing part 3 is defined as the storage position P of the memo table main body 2 and
Is lifted forward and upward via the memo table support arm 20 and rotated to the position where the memo table body 2 is horizontal with respect to the memo table support arm 20 (shown in FIG. 5).
Is the use position Q.

The auxiliary arm 21 is formed in a shape curved downward as a whole. The front part of the auxiliary arm 21
The memo table support arm 20 is rotatably attached to a portion deviated forward of the support shaft 24 by a support shaft 31 composed of a bolt. Further, the rear part of the auxiliary arm 21 and the upper end part of the guide arm 22 are rotatably attached by a support shaft 32 made of bolts. Further, the lower end of the guide arm 22 is rotatably attached to the inner plate 16 by a support shaft 33 composed of a bolt. Therefore, the front part of the auxiliary arm 21 is driven via the support shaft 31 in conjunction with the rotation of the memo table support arm 20, and
The rear portion is guided by the guide arm 22 and rotates around the support shaft 32 in conjunction with the following operation, thereby performing a swing operation as a whole.

When the memo table main body 2 is at the use position Q, the memo table support surface 34 formed on the upper surface of the front portion of the auxiliary arm 21 contacts the lower surface of the bracket 27, and The main body 2 is supported horizontally. Here, when the memo table main body 2 is lifted and the memo table support arm 20 is rotated rearward and downward, the auxiliary arm 21 retreats toward the memo table storage unit 3 while tilting forward in the first half of rotation, and rotates. In the latter half of the movement, a swinging operation is performed in which the robot moves backward while tilting backward. And finally the memo table body 2
Is guided to the accommodation position P via the memo table support arm 20, and the entire auxiliary arm 21 is
Drawn inside.

By the way, the spacer 25 is
When 1 is in the protruding position, it also functions as a stopper that regulates its rotation range. That is, as shown in FIG.
When the memo stand main body 2 is in the use position Q, the auxiliary arm 21
Are in contact with the spacer 25. As a result, the memo table support arm 20 moves the memo table body 2 to the use position Q.
The rotation of the auxiliary arm 21 is prohibited from rotating further upward beyond the original position to be held by the auxiliary arm 21. Behind the spacer 25, the memo support arm 20 when the memo support main body 2 is at the storage position P is provided.
Is provided with a stopper 35 for further restricting the rearward rotation.

The damper 23 is rotatably mounted between a part of the guide arm 22 and the inner plate 16 by a bolt 36. This tamper prevents the memo table main body 2 from being suddenly pulled into the memo table storage unit 3 by preventing the guide arm 22 from swinging abruptly.

Further, a lock lever 8 commonly used for the opening lock mechanism 7 and the lid closing mechanism 10 penetrates in the left-right direction and extends in the front-rear direction. A connection hole 38 rotatably connected to the lid 6 is provided. The lock lever 8 is supported so as to be slidable in the front-rear direction with respect to the memo table housing 3. Specifically, the lock lever 8 is supported from below by, for example, a bracket or a rail (not shown) fixed to the inner plate 16. Slot 3 of lock lever 8
7 is an auxiliary arm 21 and a guide arm 2
2 and supported. That is, the lock lever 8
Is sandwiched between the auxiliary arm 21 and the guide arm 22. Accordingly, the lock lever 8 is slid via the support shaft 32 by the swing of the auxiliary arm 21 and the guide arm 22, so that the long hole 37 and the support shaft 32 constitute a cam mechanism.

Here, the fixing means 9 for fixing the lock lever 8 to the open position O when the memo table main body 2 is at the use position Q includes a support shaft 32 and a front edge 39 of a long hole 37. Therefore, when the auxiliary arm 21 and the guide arm 22 swing and approach the foremost end, the support shaft 32 abuts on the front edge 39 of the long hole 37 and pushes the lock lever 8 forward to fix the lock lever 8 at the open position O. .

The displacement means 11 for sliding the lock lever 8 in the direction in which the lid 6 closes when the memo table main body 2 is at the storage position P has a support shaft 32 and a rear edge 40 of a long hole 37. I have. For this reason, the auxiliary arm 21 and the guide arm 2
2 swings toward the rear end, the support shaft 32
The lock lever 8 is pushed backward by contacting the rear edge 40 of the lock lever 8.

The connecting hole 38 is fitted in an opening / closing pin 41 attached inside the upper part of the lid 6. Therefore, the lid 6 is opened via the opening / closing pin 41 when the lock lever 8 slides forward, and the lid 6 is opened via the opening / closing pin 41 when the lock lever 8 slides backward.
Closes.

The operation of the above memo table will be described below.

The memo table main body 2 at the storing position P is entirely stored in the hollow portion S between the side plates 16 and 17 of the memo table storing section 3. At this time, the memo table main body 2 is stably positioned at the accommodation position P by its own weight. Also, lock lever 8
Is closed to the rear end as shown in FIG. 1, so that the lid 6 is pulled backward and closed against the torsion coil spring of the hinge 19.

Then, in order for the occupant to use the memo table main body 2, the lid 6 is first opened. As a result, the lock lever 8 is pulled slightly forward, so that the memo support 4 and the memo table main body 2 are also pulled slightly forward. Therefore, the occupant can easily pinch and pull out the memo table main body 2.

[0040] Then, when pulling out the edge of the note rest body 2 upwardly before picking with the fingers, memo board support arm 20 is picked from the note block housing portion 3 rotates about the support shaft 24. At this time, the support shaft 3 is attached to the memo support arm 20.
The auxiliary arm 21 connected via 1 is pulled out from the memo table housing 3 in conjunction with the auxiliary arm 21. The support shaft 32 at the rear of the auxiliary arm 21 is
It is guided by 2 and swings.

Further, the memo table support arm 20 is rotated to a position where the rotating pin 30 becomes horizontal. With this rotation, the auxiliary arm 21 cooperates to bring the memo table support surface 34 adjacent to the front end of the memo table support arm 20. Until this time, the memo table main body 2 is in a vertical state.

Then, the memo stand main body 2 is turned around the rotation pin 30 toward the seat 15. As a result, the lower surface of the bracket 27 supporting the memo table main body 2 is placed on the memo table support surface 34 of the auxiliary arm 21, and the memo table main body 2 is located at the use position Q. The memo table main body 2 at the use position Q gives a moment to the memo table support arm 20 in a direction of rotating backward and downward. Here, this moment is the memo table body 2
Is set to be smaller to some extent than the moment required to lift the motor by rotating it around the rotation pin 30 in the reverse direction. For this reason, the memo table main body 2 and the bracket 27 in which the memo table support arm 20 and the auxiliary arm 21 straddle therebetween.
Therefore, the entire body including the guide arm 22 is in a constrained chain state, and the memo table main body 2 is stably held at the use position Q. At this time, the stability of the memo table main body 2 increases as the load acting on the memo table main body 2 increases. Therefore, according to the present embodiment, when the memo table is used, a sufficient load supporting area for the memo table main body 2 can be secured, so that the memo table main body 2 can be supported stably without difficulty.

When the memo table main body 2 is at the use position Q, the lock lever 8 is fixed to the open position O by the fixing means 9, so that the lid 6 is locked while being opened.
Therefore, the lid 6 can be prevented from closing when the memo table main body 2 is used, so that the memo table main body 2 can be easily stored without hitting the lid 6 when the memo table main body 2 is stored in the memo table storage section 3. Thus, for example, when a seated person flips up the memo table main body 2 in an emergency, the memo table main body 2 is stored as it is and does not hinder the passage.

On the other hand, when the memo stand main body 2 is accommodated, the memo stand main body 2 at the use position Q is grasped and rotated around the rotating pin 30 in the reverse direction to the above-described procedure and lifted. Thereby, the memo table main body 2 and the auxiliary arm 21 are separated from each other, and the integrated state of the memo table support arm 20 and the auxiliary arm 21 is released.

Further, the memo table main body 2 is raised up to the vertical state, and the memo table support arm 20 is rotated forward and downward by utilizing the own weight of the memo table main body 2 from that position. As a result, the auxiliary arm 21 performs a swinging operation opposite to that at the time of the pull-out described above. Therefore, the memo table main body 2, the memo table support arm 20, and the auxiliary arm 21 are accommodated in the memo table accommodating portion 3, and the memo table main body 2 is again located at the accommodating position P.

In particular, when the memo table main body 2 is released vertically after the memo table main body 2 is placed vertically upward, the memo table support arm 20 is subject to its own weight and a moment due to the own weight of the memo table main body 2 in the initial stage of the accommodating operation. When the swing speed of the guide arm 22 becomes equal to or higher than a predetermined value, the acceleration is suppressed by the action of the damper 23. Therefore, relatively gentle and smooth behavior is ensured.

Further, as the memo table main body 2 approaches the accommodation position P, the lock lever 8 slides rearward. And
When the memo stand main body 2 is positioned immediately before the accommodation position P, the lid 6 is automatically closed by the action of the displacement means 11. Therefore,
The lid 6 automatically closes when the memo table main body 2 is stored in the memo table storage section 3.
Can be prevented from being obstructed with the door open. Thereby, for example, in a case where a seated person jumps up the memo table main body 2 and is stored as it is in an emergency, it is possible to prevent the lid 6 from hindering the passage.

Further, in the memo table 1, the memo table main body 2 at the use position Q can be located at the accommodation position P without necessarily standing up to the vertical state. That is, if the memo table main body 2 is slightly lifted up from the memo table support surface 34 of the auxiliary arm 21 and the integrated state of the memo table support arm 20 and the auxiliary arm 21 is released, the upward lifting force of the memo table main body 2 is reduced. When not in operation, the memo table support arm 20 immediately starts rotating around the support shaft 31. As a result, the auxiliary arm 21 also moves backward while being tilted forward, so that the rotation pin 30 of the memo table main body 2 gradually changes from the horizontal state to the forward tilt state as shown in FIG. The operation that the base body 2 rotates around the rotation pin 30 occurs simultaneously. As a result, the memo table body 2
Performs an operation of retreating forward and outward as viewed from the seated person.

Further, when the seated person lifts the memo table main body 2 at the use position Q to a vertical state and then accommodates the memo stand main body,
The storage operation can be performed with an arbitrary lifting amount between when the memo table main body 2 is slightly lifted and then stored. The operation of slightly lifting and housing the memo stand main body 2 in this manner is naturally given by, for example, an operation in which the memo stand main body 2 is flipped up when the occupant stands up unconsciously from the chair 12. And in any case, the memo table body 2
Is finally stored in the space S.
Of course, the same applies when the memo table main body 2 is pulled out, and if the turning operation around the rotation pin 30 is simultaneously advanced from the middle without necessarily being lifted to the vertical position, the use position Q can be shortened. Can be withdrawn.

As described above, according to the memo table 1 of the present embodiment, when the memo table body 2 is not used, the memo table body 2 and the memo table support 4 are completely housed in the memo table housing 3 and Since the lid 6 is automatically closed, the usability, appearance, and the like of the chair 12 itself including the memo table 1 can be effectively improved.

Further, in the present embodiment, if the memo table main body 2 at the use position Q slightly floats from the auxiliary arm 21, the memo table support arm 20 and the auxiliary arm 21 are released from the restraint. , Not necessarily the memo stand body 2
Does not need to be lifted from the use position Q to the vertical state and accommodated therein, and the memo table main body 2 can be quickly retracted from the front surface of the seated person by the upward and outward movement. Therefore, when an emergency evacuation is required as in the case of an earthquake or the like, a quick evacuation operation of the occupant can be guaranteed, and the safety is extremely excellent. Of course, since a separate lock mechanism for holding the memo stand main body 2 at the use position Q is not required, it is effective in reducing the number of parts and the number of manufacturing steps.

Further, in the present embodiment, all the constituent members of the memo support 4 are used as the support 1 of the chair with little spatial restriction.
Since it is mounted in the hollow portion S, a relatively large damper 23 or the like can be employed without difficulty in order to perform a desired operation. Therefore, the memo stand body 2
The desired function for using and storing the can be easily provided.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the present embodiment, the lock lever 8 is supported so as to be slidable in the front-rear direction with respect to the memo table holder 3 and slides with the opening and closing of the lid 6, but is not limited thereto. As shown in FIGS. 8 to 10, the cover 6 is slidably supported in the left-right direction with respect to the
