As shown in FIG. 4, an annular stopper 58 is integrally formed below the longitudinally intermediate portion of the support post 32 of the stool support 26 described above. Further, the kitchen stool 24 is rotatably supported above the stopper 58 in the support post 32.

The kitchen stool 24 includes a cushion section 60 on which a kitchen worker sits, a cushion support section 62 formed in an L shape in side view to support the cushion section 60, a cushion support section 62 and a stool support section. And a connecting portion 64 connecting the 26 support posts 32 to each other.

More specifically, as shown in FIG. 8, the connecting portion 64 is formed in a pipe shape, and is inserted through the support post 32. Further, a rotation operation knob 66 is attached to an intermediate portion in the longitudinal direction of the connecting portion 64. The rotation operation knob 66 includes a gripper 66A and a gripper 66.
A fixed shaft 66B protrudes from the axis of A and has a male screw formed on the peripheral surface of the distal end. The distal end of the fixed shaft 66B of the rotary operation knob 66 is formed on the peripheral wall of the connecting portion 64 and is screwed into a through hole 68 having an internal thread formed on the inner peripheral surface. Thereby, it comes into contact with the peripheral surface of the support post 32.

As shown in FIG. 9, the cushion support 62 is configured as an air damper using a plurality of cylinders. The air cylinders 70 and 72 that are expanded and contracted as necessary are covered with a cylindrical cover 74. The height adjustment of the cushion portion 60 is performed by grasping and pressing a height adjustment lever 76 protruding from the cushion support portion 62 or by lifting the same.

Next, the operation and effect of this embodiment will be described. When a kitchen worker sits on the cushion portion 60 of the kitchen stool 24 to perform kitchen work,
First, the kitchen stool 24 is adjusted.

First, the grip portion 66A of the rotary operation knob 66 is gripped and rotated in the unlocking direction, and the kitchen stool 2 is rotated.
4 is rotatable around the support post 32.
Next, after the kitchen stool 24 is rotated in the direction of the arrow ω in FIG. 4 so that the kitchen stool 24 faces the front with respect to the kitchen main body 12, the grip portion 66A is again gripped and rotated in the lock direction. Thereby, the rotary operation knob 6
6, the tip of the fixed shaft 66B abuts on the peripheral surface of the support post 32, and the kitchen stool 24 is in a non-rotating state.

Next, the height adjusting lever 76 is gripped and pulled up. Accordingly, the air cylinder 70, 72 of the cushion support portion 62, extended by the pressure inside the air the arrow Z ₁ direction in FIG. 4. In this state, a kitchen worker while applying weight seated on the cushion portion 60, pushing down the cushion portion 60 in the arrow Z ₂ direction in FIG. 4. When the cushion portion 60 has reached an appropriate height, the height adjustment lever 7
When the user releases the hand from 6, the expansion / contraction operation of the air cylinders 70 and 72 is stopped, and the cushion portion 60 is held at that height.

When the above adjustment work is completed, the kitchen worker sits on the cushion section 60 and performs the kitchen work. At this time, since the concave portion 14 functioning as a knee space is formed on the front side of the kitchen main body 12, the knee of the kitchen worker does not interfere with the kitchen main body 12.

Here, the kitchen stool 24 may be used to take an object placed in another part of the kitchen main body 12 while performing a certain operation, or to perform the next operation after a certain operation is completed. If it is possible to move laterally along the kitchen main body 12 while sitting on the kitchen, it is very convenient for a kitchen worker. However, if the moving direction of the kitchen stool 24 is unstable (that is, the kitchen stool 24 moves untracked), it may hinder the kitchen work.

In this case, in this embodiment, if the kitchen worker applies force while holding the edge of the kitchen body 12 by hand,
Kitchen stool 24 can be easily laterally moved in the arrow X ₁ direction or direction of arrow X ₂ in FIG. 4 along the upper rail 16 and lower rail 18 via the stool support 26. That is, according to the present embodiment, the kitchen stool 24 does not move untracked. As a result, according to the present embodiment, the stability of the kitchen stool 24 during movement can be improved.

After the kitchen stool 24 is moved to the predetermined position in the lateral direction as described above, the pedal body 42A of the pedal 42 is depressed in the direction of arrow A in FIG. The pedal 42 swings, and the rod 48 is pushed down in the direction of arrow D in FIG. As a result, the brake shoe 52 connected to the rod 48 is pressed against the bottom surface of the lower rail 18, and the kitchen stool 24 is reliably stopped. Kitchen stool 24
Is stopped, the pedal 42 is swung in the direction of arrow B in FIG. 7 until the pedal arm 42B comes into contact with the stopper pin 56 by the urging force of the tension spring 54 when the foot is released from the pedal body 42A. Thereby, the rod 4
8 rises in the direction of arrow C in FIG. 7, whereby the brake shoe 52 is separated from the bottom surface of the lower rail 18 and returns to the original state.

On the other hand, when the kitchen work is completed,
The kitchen stool 24 can be stored in the recess 14 of the kitchen main body 12 as described below. First, while raising the height adjustment lever 76, the cushion 60 is pushed down to the lowest position using the weight of the kitchen worker. Next, the kitchen worker has kitchen stool 2
4, the user grips the grip 66A of the rotary operation knob 66 and rotates it in the unlocking direction. After that, the kitchen stool 24 may be rotated around the support post 32 and housed in the recess 14 of the kitchen body 12.

As described above, according to the present embodiment, the kitchen stool 24 is rotatably supported by the support post 32 of the stool support 26, and the kitchen stool 2
Since the kitchen stool 24 can be stored in the concave portion 14 by rotating the kitchen stool 24, the kitchen stool 24 does not become an obstacle when the kitchen stool 24 is not used.

When the configuration of the present embodiment is adopted, FIG.
As shown schematically at 0, when a kitchen worker sits on the kitchen stool 24, the own weight P acts on the kitchen stool 24. Due to this own weight P, a rotational moment M acts on the support post 32 of the stool support 26. For this reason, a horizontal pressing force H ₁ on the kitchen stool 24 side acts on the upper rail 16 on the upper slide bar 28 side of the stool support 26. Moreover, the lower slide bar 30 side of the stool support 26, together with water Hiraoshi pressure of H ₂ Kitchen body 12 side acts on the lower rail 18, a vertical pressing force V ₂ acts.

Focusing on the relationship between the acting loads, in the present embodiment, an upper roller 34 which is a vertical axis roller is disposed on the upper slide bar 28 side, and a lower first roller which is a vertical axis roller is disposed on the lower slide bar 30 side. Since the roller 36 and the lower second roller 38 which is a horizontal axis roller are arranged, the peripheral surface of the upper roller 34 is securely pressed against the inner surface of the side wall of the upper rail 16, and the peripheral surface of the lower first roller 36 is pressed on the inner surface of the side wall of the lower rail 18. The peripheral surface of the lower second roller 38 is the lower rail 1.
8 is securely pressed against the bottom surface. Therefore, the kitchen stool 24 can be smoothly moved along the upper rail 16 and the lower rail 18.

Further, according to the present embodiment, as described above, the kitchen stool 24 is configured to move laterally along the upper rail 16 and the lower rail 18 via the stool support 26, so that the influence of unevenness of the floor surface is obtained. I do not receive. That is, in a dining room in which storage under the floor or the like is possible, the floor surface may have some irregularities. Therefore, in the case of a kitchen stool with casters separate from the kitchen main body 12, smooth movement tends to be hindered because of overcoming irregularities on the floor surface. However, according to the present embodiment, the kitchen stool 24 does not move on the floor surface, so that a smooth lateral movement of the kitchen stool 24 can be secured.

According to the present embodiment, the kitchen stool 24 is connected to the upper rail 1 via the stool support 26.
6 and the lower rail 18 (that is, the upper slide bar 28 and the lower slide bar 30 of the stool support 26 are restrained by the upper rail 16 and the lower rail 18).
The kitchen stool 24 does not fall when the posture is changed. In order to further secure this effect, a configuration may be adopted in which the upper slide bar 28 and the lower slide bar 30 are inserted into the upper rail 16 and the lower rail 18, respectively.

In the present embodiment, the kitchen stool 24 is rotated with respect to the support post 32 so that the kitchen stool 24 can be stored in the recess 14 of the kitchen main body 12 when the kitchen stool 24 is not used. Although the configuration is possible, the kitchen stool 24 may be configured to be unable to rotate with respect to the support post 32 in relation to the present invention described in claim 1.

Further, in the present embodiment, the above-described braking means including the pedal 42, the brake shoe 52, and the like is used to stop the lateral movement of the stool support 26 of the kitchen stool unit 22, but the reverse usage is used. You may do. That is, normally, the brake shoe 52 is pressed against the bottom surface of the lower rail 18 by the urging force of the urging means to apply the brake, and when moving in the lateral direction, the pedal 42 is depressed against the urging force of the urging means. Brake shoe 52
May be separated from the bottom surface of the lower rail 18. In such a configuration, the kitchen stool 24 does not slightly move due to the movement of the kitchen worker when working, so it seems that some people feel it easier to work. Which configuration to adopt may be determined according to the needs of the target consumer group.
