The movement blocking mechanism is configured so that it is not released.
Further, as shown in FIG. 8, a pair of relatively small single-wheel casters 62 are provided on the right and left sides at appropriate positions on the bottom surface portion 44 of the storage drawer portion 4, and the tip of the upper surface portion 262 on the frame body 2 side. The part 242 is provided with a sliding turning ball 28 fitted with a pair of large turning spheres on the left and right sides between the bottom face 441 of the bottom face part 44 of the storage drawer part 4. With the single wheel caster 62 and the sliding ball 28, the storage drawer 4 can move smoothly and freely.

[２人用のキャスター付スツールとして使用の場合]
次に、２人用のキャスター付スツールを使用の場合を、図７から図９を参照しながら説明する。
収納引出部４の前面部４１には回動自在の第１の前面板４１１と、その裏側にはクッション４１２が設けられて回動座部５が形成されている。第１の前面板４１１の背後には、更に収納引出部４に対して固定され、収納部の前面板になる第２の前面板４１４が設けられている。
前記回動座部５は収納引出部４の前面部４１、すなわち第１の前面板４１１の上端の上端部４１３には、上端部４１３を中心として、第１の前面板４１１が反転回動する回動機構８が設けられ、この回動機構８はゆっくり回転するようなロータリダンパ８１が用いられ、一方を収納引出部４の左右の側面板４６に固定し、他方を第１の前面板４１１の左右両端に支持している。 [When used as a stool with two casters]
Next, the case of using a stool with two casters will be described with reference to FIGS.
The front part 41 of the storage drawer 4 is provided with a first front plate 411 that is rotatable, and a cushion 412 is provided on the back side thereof to form a rotary seat part 5. Behind the first front plate 411 is further provided a second front plate 414 that is fixed to the storage drawer 4 and serves as a front plate of the storage unit.
The rotary seat portion 5 has a front surface portion 41 of the storage drawer portion 4, that is, an upper end portion 413 at the upper end of the first front plate 411, and the first front plate 411 rotates around the upper end portion 413. A rotary mechanism 8 is provided. A rotary damper 81 that rotates slowly is used. One of the rotary mechanisms 8 is fixed to the left and right side plates 46 of the storage drawer 4, and the other is a first front plate 411. It is supported at both the left and right ends.

したがって、２人用のキャスター付スツールとして使用する場合は、先ず、収納引出部４には引き出し、移動を阻止する移動阻止機構(２７,４５) が働くまで目一杯引出し、次に図９(ａ)に示すように、第１の前面板４１１の下側の反転把持部４３を把持して、図９(ｂ)に示すように下部を持ち上げ、図９(ｃ)に示すように第１の前面板４１１の裏側のクッション４１２が上側になるように反転回動し、図９(ｄ)に示すように固定座部３と回動座部５を並べて固定する。
この回動座部５の幅、すなわち、第１の前面板４１１及びクッション４１２の幅(図８で左右幅)は、収納引出部４が目一杯引き出された状態での固定座部側面３２までの幅とほぼ一致させているので、移動阻止機構(２７,４５) が収納引出部４の前進を阻止し、回動座部５を反転回動した回動座部側面５１が後退を阻止するので、両者で回動座部５の進退を阻止し、結果とて固定座部を固定している。
こうして、スツールがさらに必要な場合でも、１人用のキャスター付スツールを２座席のスツールとすることができ、スツールが小型であるので狭い病室等にも常備できる。 Therefore, when used as a stool with a caster for two persons, first, the storage drawer 4 is pulled out until it is fully pulled out until the movement blocking mechanism (27, 45) for blocking the movement works. ), The lower holding part 43 on the lower side of the first front plate 411 is held, the lower part is lifted as shown in FIG. 9 (b), and the first part as shown in FIG. 9 (c). As shown in FIG. 9D, the fixed seat portion 3 and the rotating seat portion 5 are aligned and fixed so that the cushion 412 on the back side of the front plate 411 is turned upward.
The width of the rotating seat 5, that is, the width of the first front plate 411 and the cushion 412 (the left and right widths in FIG. 8) is the same as the side surface 32 of the fixed seat when the storage drawer 4 is fully pulled out. Therefore, the movement blocking mechanism (27, 45) prevents the storage drawer 4 from moving forward, and the rotating seat portion side surface 51 that rotates and rotates the rotating seat portion 5 prevents backward movement. Therefore, both of them prevent the rotation seat 5 from moving forward and backward, and as a result, the fixed seat is fixed.
Thus, even when a stool is further required, a stool with a caster for one person can be a two-seat stool, and since the stool is small, it can be used even in a narrow hospital room or the like.

以上のように、本発明のキャスター付スツールの実施例によれば、１人用のキャスター付スツールとして使用でき、この場合は、キャスター付スツールの固定座部を使用しながら、収納引出部を側部から引き出すことができ、開口面積を大きくすることが可能な上部開口から必要な物品を出し入れすることが容易となる。
また、複数のキャスターを一括して同時にロック及びロック解除操作を行うキャスター操作レバーを設けているので、スツールの移動と固定が簡単となる。
更に、スツールが必要な場合でも、２座席用キャスター付スツールとして使用可能となり、特に、狭い病室等にも、必要であれば２座席用のキャスター付スツールとして常備できる。
具体的には、収納引出部の引出側の底部には１対のキャスターを設けので、僅かな力でスムースに引き出すことができ、収納引出部と固定座部の枠体とにロック機構を設けたので収納引出部が不意に出るようなことを防止することができ、回動座部は収納引出部の前面部の上部先端を中心に回動する回動機構を設けたので、簡単に収納引出部の上部開口を蓋を兼ねた２人用の座部とすることができ、回動座部を単に反転回動して固定座部と回動座部とを並べるだけで、固定座部を固定して、簡単に２人用のキャスター付スツールとすることができる。
なお、本発明の特徴を損なうものでなければ、上記の実施例に限定されるものでないことは勿論である。 As described above, according to the embodiment of the stool with a caster according to the present invention, it can be used as a stool with a caster for one person. It is possible to pull out from the part, and it becomes easy to put in and out necessary articles from the upper opening that can increase the opening area.
In addition, since a caster operation lever that simultaneously locks and unlocks a plurality of casters is provided, the stool can be easily moved and fixed.
Furthermore, even when a stool is required, it can be used as a stool with a caster for two seats, and can be used as a stool with a caster for two seats if necessary, particularly in a narrow hospital room.
Specifically, a pair of casters is provided at the bottom of the drawer side of the storage drawer, so it can be pulled out smoothly with little force, and a lock mechanism is provided between the storage drawer and the frame of the fixed seat. Therefore, it is possible to prevent the storage drawer part from unexpectedly coming out, and the rotating seat part is provided with a rotation mechanism that rotates around the top end of the front part of the storage drawer part.
