  FIG. 1 is a cross-sectional view of an essential part showing an outline of a wagon with casters of the present invention.

  The wagon 1 with casters of the present invention includes casters at four locations, front, rear, left and right, and the casters are arranged at predetermined positions on the bottom surface of the wagon body 2. The front and rear casters 3 and 4 are separated by a predetermined distance a that can prevent the wagon body 2 from falling over, and this position is a fixed position. The wagon body 2 can store various fixtures used in the kitchen, and can also be used as a stool.

  The caster-equipped wagon 1 of the present invention is housed inside the kitchen cabinet 5. It can be pulled out from the kitchen cabinet 5 when used, and can be stored inside the kitchen cabinet 5 after use.

  And in the wagon 1 with a caster of this invention, the caster 4 which will be located in the kicking part 6 side of the kitchen cabinet 5 moves to the inside direction of the kitchen cabinet 5 from a fixed position at the time of the accommodation to the kitchen cabinet 5. . The moving distance of the casters 4 is b. At this time, the distance between the front and rear casters 3 and 4 is ab. Therefore, in the state where the wagon 1 with casters of the present invention is housed in the kitchen cabinet 5, the casters 4 located on the kick section 6 side do not protrude into the kick section 6 and are housed inside the kitchen cabinet 5. . For this reason, the caster 4 does not protrude into the kicking portion 6 even at a location where the depth is shallow due to the arrangement of piping or the like. The toes of the feet are prevented from hitting, and various operations can be performed smoothly at a standing position close to the kitchen cabinet 5.

  Moreover, in the wagon 1 with a caster of the present invention, when it is pulled out from the kitchen cabinet 5 in use, the caster 4 on the side of the housed kick section 6 is returned to a fixed position, that is, separated from the caster 3 by a distance b. The distance between the front and rear casters 3 and 4 is a. This state is a stable state with no fear of falling, and the wagon 1 with casters can be used for various operations.

  As described above, the caster-equipped wagon 1 of the present invention retains the ease of use as a wagon as it is, and when stored in the kitchen cabinet 5 when not in use, the kitchen cabinet 5 has a kick-in portion 6 having a certain depth. Can be formed. The toes of the foot do not hit, and various operations can be performed at an appropriate standing position from the kitchen cabinet 5.

  Examples of the mechanism for moving the caster 4 located on the side of the kick-in portion 6 when the wagon 1 with casters is stored in the kitchen cabinet 5 include the following.

  In the example shown in FIG. 2, the caster 4 is disposed on the movable jig 7 that moves in parallel with the direction in which the wagon 1 with casters is pulled out and stored. The parallel movement of the movable jig 7 is guided by a guide 8. Both the movable jig 7 and the guide 8 are disposed on the bottom surface 9 of the wagon 1 with casters.
