In the former clothes dryer stand, the height position of the shelves can be adjusted in three to five steps by changing the mounting position of the columns. If you want to change the height position of the shelf board after installing it on the shelf board, lower the clothes dryer you installed from the shelf board once to change the mounting position of the prop, and place it on the shelf board again. It is necessary to place it, and its operation is extremely troublesome. Also, since the height of the water tap for supplying water to the washing machine is not constant, even if the water tap can be used by slightly changing the height of the shelf board, the height of the shelf board can be obtained. Since the position is changed stepwise, the height position of the shelf board is changed by at least one step height, which causes a problem that the clothes dryer cannot be adjusted to the desired height position. In addition, the latter clothes dryer stand has a problem that the height position of the top plate cannot be changed. In view of such a problem, the present invention aims to provide a pedestal capable of continuously adjusting the height position of a frame member to which a top plate is attached and having excellent safety when changing the height position. And

And a stopper member that should prevent the second rod from being driven by the operation unit.

In the second invention, the obstacle detecting member moves upward when the obstacle is detected. Then, the stopper member that interlocks with the obstacle detection member moves up and comes into contact with the operating portion, and prevents the operating portion from driving the second rod and prevents the piston from moving. Then, the height position of the pedestal is held at the height position at that time. Thereby, the pedestal can be held at the height position of the pedestal when the obstacle is detected, and the obstacle is not damaged.

In the rack of the clothes dryer according to the third aspect of the invention, the pedestal is composed of a frame member of a cylindrical body and a top plate attached to the frame member, and the operation section is arranged in the cylindrical body. It is characterized by being installed.

In the third aspect of the invention, the operating portion is located in the cylinder body, and when the movement of the operating portion is blocked, the driving of the second rod is blocked. As a result, the operating portion is protected by the tubular body and there is no risk of malfunction.

According to a fourth aspect of the present invention, there is provided a pedestal for a clothes dryer in which the height of the pedestal for installing the clothes dryer can be adjusted with respect to a predetermined portion other than the pedestal. It is characterized in that it is provided with an elevating means capable of elevating the pedestal steplessly with the machine installed.

According to the fourth aspect of the present invention, when the clothes dryer is installed on the pedestal and the pedestal is moved up and down with the clothes dryer installed, the pedestal moves up and down steplessly. As a result, the height of the pedestal can be adjusted to a desired position without lowering the clothes dryer from the pedestal.

Next, a method of using the rack of the clothes dryer thus constructed will be described. Position the clothes dryer rack at the location where the washing machine and clothes dryer should be installed. Then, the pedestal composed of the top plates 9 and 10 and the frame body Z is placed below the frame body Z at a height position where the washing machine can be placed, and the front side of the washing machine is placed below the frame body Z. On top of the tops 9 and 10,
The clothes dryer is placed with its front side facing forward, and bolts are inserted into the mounting holes A provided in the top plates 9 and 10 to attach the clothes dryer to the top plates 9 and 10.

Now, the clothes dryer is adjusted to the desired height position. Now, when the height of the clothes dryer is high, pass the hand under the front frame member 7 to raise / lower the lever 13
The tip end side of the elevating lever 13 is pushed up slightly upward. Then, the tip end of the rod 12a is pushed down against the urging force of the coil spring 12h by the base end side of the elevating lever 13, and the valve 12d is pushed down. As a result, the small hole 12e is opened, the high pressure gas and oil in the cylinder 12b below the moving valve 12c flow into the cylinder 12b above the moving valve 12c through the small hole 12e, and the moving valve 12c
Can be moved. Then, when the frame Z is pushed down by hand, the weight of the clothes dryer is added and the moving valve 12c is gradually lowered,
As a result, the height of the clothes dryer is gradually lowered.

When it is confirmed that the height of the clothes dryer is at the desired height, the lifting lever 13 is released, and the rod 12 is urged by the coil spring 12h.
When a is pushed up, the valve 12d comes into close contact with the lower surface of the moving valve 12c and closes the small hole 12e. As a result, gas and oil do not flow through the small hole 12e, and the moving valve 12
The movement of c is blocked and the clothes dryer is held at the desired height. After that, by operating the elevating lever 13 again, the height of the clothes dryer can be lowered again as described above, and the height position of the clothes dryer can be adjusted steplessly as desired.

On the other hand, when raising the height position of the clothes dryer, the tip of the elevating lever 13 is pushed up by hand as described above. Then, the valve 12d is pushed down by the rod 12a to open the small hole 12e. Then, the moving valve 12c becomes movable. Therefore, when the frame Z is lifted by the hand on the opposite side where the elevating lever 13 is not operated, the gas and oil in the cylinder 12b above the moving valve 12c pass through the small hole 12e and move to below the moving valve 12c. It flows into the cylinder 12b and the moving valve 12c is moved upward, whereby the frame Z moves upward and the height position of the clothes dryer rises.

Since the gas spring 12 is filled with high-pressure gas and the internal pressure is high, the pressure is high.
When the clothes dryer can be moved up or down with a small operating force acting on 12c and the hand is lifted from the lifting lever 13 at the desired height position, the small hole 12e is opened by the valve 12d. The clothes dryer can be fixed in that position by blocking the movement of the moving valve 12c. Therefore, when changing the height position of the clothes dryer, the height position of the frame Z can be continuously adjusted as desired, and the height position of the clothes dryer can be smoothly adjusted with a small operating force. You can do it.

Next, an obstacle exists below the top plates 9 and 10 because the lid of the washing machine installed below the frame Z to which the top plates 9 and 10 are attached is opened. In this case, when the frame Z is lowered to lower the height position of the clothes dryer as described above, the obstacle detection part 18b of the obstacle detection plate 18 extending to the lower surface side of the front frame member 7 is Touch the open lid of the washing machine. Then, the obstacle detection plate 18 is moved upward against the biasing force of the coil spring 19. As a result, the stopper shaft attached to the obstacle detection plate 18
The height of 17 moves upward and pushes up the base end of the elevating lever 13. That is, the tip end of the elevating lever 13 is pushed down. As a result, the rod 12a is forcibly moved upward by the urging force of the coil spring 12h, the valve 12d immediately closes the small hole 12e, and the movement valve 12c is prevented from moving.
The downward movement of the frame body Z is prevented, and the frame body Z, which is lowered together with the top plates 9 and 10, does not come into contact with the open lid of the washing machine, and damage to the lid of the washing machine can be prevented.

Further, even if the hand is located between the front frame member 7 and the lid of the washing machine, the hand is not caught between the front frame member 7 and the lid of the washing machine to be injured. The sensitivity with which the stopper shaft 17 operates can be adjusted according to the height of the stopper shaft support portion 5b with which the stopper shaft 17 is in contact.

[0031]

As described in detail above, according to the present invention,
The height position of the pedestal on which the clothes dryer is installed can be adjusted steplessly with a small operation force and can be fixed at a desired height position with one touch. Further, even if there is an obstacle below the pedestal, there is no risk of the pedestal colliding with the obstacle and damaging the obstacle. For example, the height position of the pedestal can be adjusted very easily and smoothly. In addition, it is possible to provide a stand for a clothes dryer excellent in safety.
