Description

  The present invention relates to a chair with a memo stand comprising a seat body on which a user can be seated, a memo stand, and a support that supports the memo stand.

  Conventionally, a chair with a memo stand has been used as a chair used in a conference room or the like. This chair with a memo stand is generally stored in a horizontal position in front of the occupant and on the side of the occupant. It is configured to be movable between the positions. By setting the memo stand to a horizontal position, the user can write a notebook or memo by spreading it or use it with a notebook personal computer.

  When chairs used in a conference room or the like can be overlapped with each other, it is convenient because a large number of chairs can be stored in a small space when not in use. However, the chair provided with the memo stand cannot be overlapped because the memo stand is in the way, and it may be difficult to store the overlap.

In view of this, conventionally, a chair has been proposed in which the main surface of the memo stand is inclined with respect to the front-rear direction in the above-described storage position in order to stack the chair with the memo stand in the front-rear direction (so-called nesting). (See Patent Document 1). In this chair, even if the chairs are close to each other in the front-rear direction, the memo stands (writing tables) can be prevented from contacting each other, so that nesting can be performed.
JP 2003-79451 A

  The memo stand provided in the chair described in Patent Document 1 described above has a rotational axis inclined with respect to the front-rear direction so that the memo stand is inclined with respect to the front-rear direction when the memo stand is in the storage position described above. The memo stand rotates around the center. As a result, the memo stand moves to a position having an inclination with respect to the front-rear direction in the storage position.

However, when the rotating shaft is inclined with respect to the front-rear direction, there are the following problems.
As shown in FIG. 9, when the front of the rotation shaft 61 is inclined so as to face the center direction of the chair, a region 62 where a load cannot be applied is generated on the memo stand 60. If there is a risk that the memo stand 60 will rotate in the direction of arrow D in FIG. 9 when a load is applied by placing an object or putting a hand on the region 62, a memo stand should be formed in the region 62. I can't.

  In some cases, it is desirable that the memo stand 60 be formed in A3 size so that an A4 size notebook can be opened. However, when the memo stand 60 is formed except for the region 62, as shown in FIG. Since the area 63 adjacent to the area 62 cannot be used for securing the A3 size area, the memo stand 60 has to be formed larger than necessary.

  On the other hand, as shown in FIG. 11, when the front of the rotating shaft 64 is inclined so as to face the outside of the chair, the region corresponding to the region 62 of FIG. 9 described above hardly occurs. However, in order to move the memo stand 60 to the storage position (the position of the memo stand 60 indicated by the broken line in FIG. 11), the distance E from the connection point 65 that supports the memo stand 60 to the center of the chair is increased. . As a result, the center of gravity of the entire chair is large, and is caused by the rotating shaft 64 side of the memo stand 60, which makes the chair unbalanced and easily rolls over. If it tried to do so, there existed a problem that the length F of the left-right direction of the memo stand 60 will become large.

  The present invention has been made to solve the above-described problem, and an object thereof is to provide a chair with a memo stand that can arrange the memo stand in an appropriate size and in an appropriate position.

The invention according to claim 1, which has been made to solve the above-described problem, is a chair with a memo stand comprising a seat body on which a user can sit, a memo stand, and a support body that supports the memo stand. The memo stand is between a horizontal position where the main surface of the memo stand is substantially horizontal and a vertical position where the main surface of the memo stand is substantially vertical, with the first rotation axis as the center. The first pivot shaft is tilted at a predetermined angle so that the front is higher with respect to the horizontal , and is seen in the front-rear direction of the seat body when viewed from above. They are arranged in a substantially parallel positional relationship.

  In the chair with a memo stand configured in this way, since the first rotation axis is inclined with respect to the horizontal, when the main surface of the memo stand is in a substantially horizontal horizontal position, as shown in FIG. The first rotation shaft 43 and the main surface 51 of the memo stand are in a positional relationship having an angle α when viewed from the side. Therefore, when the memo stand is rotated to the vertical position, the main surface 51 of the memo stand is viewed from above as shown in FIGS. 5 (a) and 6 (a). 43 is inclined relative to the angle α described above.

  That is, the main surface of the memo stand is in a vertical position with respect to the front-rear direction necessary for nesting, even though the first rotation shaft 43 is substantially parallel to the front-rear direction of the chair as viewed from above. The inclination angle α can be obtained.

  Thus, if it is a chair with a memo stand of this invention, let the 1st rotating shaft used as the center of rotation between the horizontal position mentioned above and the vertical position mentioned above be substantially parallel to the front-back direction of a seat. Can be arranged in a positional relationship.

  Thereby, in the conventional chair with a memo stand, there is no area where no load can be applied on the memo stand, such as a case where the front of the first rotation shaft is inclined toward the center of the chair. In addition, in the conventional chair with a memo stand, there is no need to largely set the above-described connection point on the outside as in the case where the front of the first rotation shaft is inclined outward.

Therefore, if it is a chair with a memo stand of this invention, a memo stand can be arrange | positioned in an appropriate position by an appropriate magnitude | size.
Moreover, the chair with a memo stand of the present invention is characterized in that the memo stand is attached to the support so as to be rotatable about a second rotation axis perpendicular to the main surface of the memo stand.

  If it is a chair with a memo stand comprised in this way, a memo stand will rotate centering on a 2nd rotating shaft. Since the second rotation axis is orthogonal to the main surface of the memo stand, when the memo stand rotates about the second rotation axis, the inclination angle of the seat base of the memo stand with respect to the front-rear direction is maintained. The position of the memo stand can be changed. Therefore, the nesting function can be stored in a position where the memo stand does not get in the way when the memo stand is not used without changing the nesting function.

Embodiments of the present invention will be described below with reference to the drawings.
(1) Configuration of Chair As shown in FIGS. 1 and 2, the chair 1 of the present embodiment includes a leg body 10, a seat body 20 on which a user can sit, and a backrest 30 on which the user leans while seated. The arm 40 and the memo stand 50 supported by the arm 40, so that so-called nesting is possible in which the arms 40 are stacked in the front-rear direction.

  The leg body 10 is disposed on both sides in the left-right direction that connect the pair of front legs 11 and the pair of rear legs 12 disposed on both sides of the seat body 20 in the left-right direction, and the front legs 11 and the rear legs 12 at the respective upper ends. A pair of connecting portions 13, a columnar member extending in the left-right direction, a connecting member 14 that connects the left and right front legs 11, and a caster 15 attached to the lower ends of the front legs 11 and the rear legs 12. Have.

The front leg 11 is arranged to tilt backward, and the rear leg 12 is arranged to tilt forward. The rear leg 12 is disposed outside the front leg 11 in the left-right direction.
The seat body 20 has a seating surface 21 on which a user is seated. A seating position (see FIG. 2) in which the seating surface 21 is substantially horizontal with respect to the front leg 11 around a rotation shaft (not shown), and a seating position. The surface 21 is attached so as to be rotatable between a standing position (see FIG. 3) in which the surface 21 is substantially vertical. The seat body 20 is supported by the connecting member 14 from below in the sitting position. When performing nesting, the seat body 20 is moved to the standing position.

The backrest 30 is fixed to the left and right connecting portions 13 at a slightly inclined angle behind the seat body 20 and supports the back of the user who is seated.
The arm 40 is substantially parallel to the front-rear direction when viewed from above and has a predetermined angle inclination from the horizontal so that nesting is possible (in this embodiment, in the present embodiment). It is attached to the left side). Further, the arm 40 is disposed on the outer side with respect to the left and right direction with respect to the rear leg 12 so that stacking described later is possible.

  A connecting portion 41 is disposed at the tip of the arm 40. An enlarged view of the vicinity of the connecting portion 41 is shown in FIG. The connecting portion 41 includes a base portion 42 fixed to the arm 40 and a first rotating portion 44 that is rotatable with respect to the base portion 42 about the first rotating shaft 43. The memo stand 50 is attached to the first rotating portion 44 so as to be rotatable about the second rotation shaft 45. The first rotation shaft 43 is inclined at a predetermined angle so that the front is higher than the horizontal, and has a positional relationship that is substantially parallel to the front-rear direction of the chair 1 when viewed from above. Further, the second rotation shaft 45 has a positional relationship orthogonal to a main surface 51 of a memo stand 50 described later, and is displaced with the rotation of the first rotation unit 44.

  The memo stand 50 rotates about the first rotation shaft 43 by rotating the first rotation portion 44 described above about the first rotation shaft 43. Further, the memo stand 50 rotates around the second rotation shaft 45.

The memo stand 50 has a main surface 51 for spreading and writing notes, memos, etc., or using a notebook personal computer. As shown in FIG. 1, the main surface 51 has left and right end portions that are substantially parallel to the front-rear direction, a front end portion that is substantially parallel to the left-right direction, and a rear end portion connected in the left-right direction. It is formed to be inclined so that the side far from the portion 41 is the front side. The memo stand 50 is supported by the connecting portion 41 on the side (the left side in the present embodiment) to which the arm 40 is attached and on the lower rear side.
(2) Operation of the memo stand When the memo stand 50 is rotated in the direction of arrow A around the first rotation shaft 43 of the connecting portion 41 from the horizontal position shown in FIGS. ) And the vertical position shown in (b). In this vertical position, the main surface 51 has a predetermined angle α with respect to the front-rear direction when viewed from above. This angle α is the same angle as the angle α formed by the first rotation shaft 43 and the main surface 51 shown in FIG. Note that the rotation around the first rotation shaft 43 of the memo stand 50 is restricted between the horizontal position and the vertical position described above by a stopper (not shown) disposed inside the connecting portion 41.

  Furthermore, when it is rotated from the vertical position described above in the direction of arrow B shown in FIG. 5 (b) around the second rotation shaft 45 of the connecting portion 41, the storage shown in FIGS. 6 (a) and 6 (b). Position. Since this storage position is along the side of the chair and is located below and behind the standing position, the memo base 50 is moved to the storage position when the memo base 50 is not used. It won't get in the way.

  Since the second rotation shaft 45 is orthogonal to the main surface 51, the angle α with respect to the front-rear direction of the main surface 51 is maintained even if the second rotation shaft 45 is rotated from the vertical position to the storage position. Note that the rotation around the second rotation shaft 45 of the memo stand 50 is restricted between the above-described vertical position and the storage position by a stopper (not shown) disposed inside the connecting portion 41.

In addition, it can be made to move to a horizontal position from a storage position by performing reversely the operation | movement which rotates to the vertical position from the horizontal position mentioned above, and a vertical position to a storage position.
(3) Nesting Operation When nesting is performed, as shown in FIG. 7A, first, the memo stand 50 is moved to the storage position, and the seat body 20 is moved to the standing position. And the chair 1 is piled up from the front-back direction. As a result, the chairs 1 overlap each other as shown in FIG. At this time, as shown in FIG. 7C, the memo stands 50 are inclined at an angle α with respect to the front-rear direction when viewed from above, so that the memo stands 50 come into contact with each other to prevent nesting. Never become. 7A to 7C show a state in which two chairs 1 are nested, but nesting is similarly possible even when there are three or more chairs.

Furthermore, the chair 1 of the present embodiment is configured to be so-called stacking in which the chairs 1 are stacked in the vertical direction. When stacking, as shown in FIG. 8A, first, the memo stand 50 is moved to the storage position, the seat body 20 is moved to the seating position, and the chair 1 is stacked in the vertical direction. Thus, the chairs 1 overlap each other. At this time, the memo stand 50 can be rotated in the direction of the arrow C by the first rotation shaft 43 as shown in FIG. Therefore, since the memo stand 50 of the chair 1 stacked from above can avoid the memo stand 50 of the chair 1 arranged below, the memo stands 50 do not come into contact with each other and prevent stacking. In addition, even if it is the structure which prevents the contact between memo stand 50 at the time of stacking by setting the vertical position and storage position of the memo stand 50 to the position which has a predetermined angle inclination from a perpendicular direction. Good.
(4) Effect The chair 1 configured in this manner has its first rotating shaft 43 arranged substantially parallel to the front-rear direction. The main surface 51 is configured to have an inclination with respect to the front-rear direction.

  Therefore, like a conventional chair with a memo stand, the memo stand becomes larger than necessary in order to secure a required area, or the connecting portion 41 is greatly arranged on the outside. The problem that the memo stand becomes unnecessarily long in order to make the balance of 1 worse or to make the memo stand reach an appropriate position is less likely to occur.

Thus, with the chair 1 of the present embodiment, the memo stand 50 can be arranged in an appropriate size and in an appropriate position while having a nesting function.
Moreover, the chair 1 of this embodiment can also implement storage by stacking by arranging the arm 40 outside the rear leg 12.
(5) Modifications The embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and can take various forms as long as it belongs to the technical scope of the present invention. Needless to say.

  For example, in the above-described embodiment, the configuration in which the memo stand 50 rotates around the first rotation shaft 43 and the second rotation shaft 45 and moves from the horizontal position to the storage position via the vertical position is exemplified. . However, the specific configuration is not particularly limited as long as the main surface 51 of the memo stand 50 can move to a positional relationship having an inclination in the front-rear direction necessary for nesting. For example, the connecting portion 41 has only the first rotation shaft 43, and the main surface 51 can be rotated from a horizontal position where the main surface 51 is horizontal to a position where the main surface 51 is substantially vertical. Can be considered.
