[Problems to be Solved by the Invention] However, in the conventional ironing board configured as described above, when the horse bed 6 is used, the iron board is moved to an upper portion of the flat board 2 to perform work. If the platform 6 is not returned to the specified position, the flat platform shield plate 40 and the horse platform shield plate
Since 31 is not switched, when the platform 6 and the flat platform 2 are frequently used, there is a problem that the time required to return the platform 6 to a predetermined position and the time to pull it out are long, resulting in poor work efficiency.

According to the present invention, by changing the length of the adjustment link connected between the horse arm lever and the rotation link, which are pushed by the horse arm by the movement of the horse platform, the operating positions of the flat base plate and the horse base shield plate are changed. It is an object of the present invention to provide an ironing board switching device in which the moving distance of the platform is shortened because it is located in front of the predetermined position of the platform.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a flat stand duct chamber and a horse stand duct chamber, which communicate with each other, at the upper part of a main body, and mounts a flat stand on the flat stand duct chamber. , A platform that horizontally moves through the horse arm is provided in the platform duct chamber, and a blower device connected to the platform duct chamber is attached to the main body to vacuum or blow the platform and the platform. ,
In an ironing board provided with a link mechanism that opens and closes the flat stand shield plate provided in the flat stand duct chamber and the horse stand shield plate provided in the horse stand duct chamber, the iron arm of the link mechanism is rotated together with the horse arm lever. It is possible to adjust the length of an adjustment link connected between the links and to adjust the position of the switching detector for switching between the flat platform and the platform, which is arranged near the horse arm lever.

[Operation] According to the present invention, when the length of the adjustment link connected between the horse arm lever and the rotation link is increased, the tip of the horse arm lever inclines toward the flat base, so that it is more than the predetermined position of the horse mount. Since the tip of the horse arm lever hits the horse arm on the flat platform side, the operator switches the flat platform shielding plate and the platform shielding plate in front of the platform without holding it up to a predetermined position. The switching work can be done quickly. Further, when the adjustment link is contracted to a predetermined length, it can be switched to the flat platform when the platform is moved to the predetermined position.

[Embodiment] Referring to FIG. 1, in an ironing board according to an embodiment of the present invention, 15 is a horse-seat duct chamber, 17 is a horse arm lever, 18 is an axial pin, 19 is a spring, 20 is a connected product, and 22 is a rotation member. A dynamic link, 23 is a connecting pin, 24 is a shaft pin, 26 is a connecting pin, and 27 is an engaging link.These configurations are almost the same as the above-mentioned conventional example, so description thereof will be omitted, but in the present embodiment, One end of the adjusting plate 41 is rotatably connected to the lower end of the horse arm lever 17 by a connecting pin 20, two elongated holes 42, 42 are formed in the adjusting plate 41, and screws 43, The adjustment link 45 is formed by fixing the adjustment plate 44 to the other adjustment plate 44 through 43 and rotatably connecting one end of the adjustment plate 44 to one end of the rotation link 22 by the connecting pin 23. A detector (for example, a limit switch) 46 that switches between the flat platform 2 and the platform 6 by the movement of the platform lever 17 is adjusted together with the adjustment link 45. Further, a stopper 47 due to the rotation of the horse arm 4 is fixed near the platform lever 17.

In the ironing board of the present embodiment configured in this way, the screws 43, 43 are loosened in the elongated holes 42, 42 of the adjustment plate 41 of the adjustment link 45 to move the adjustment plate 41, and the screws 43, 43 are fixed. The length of the adjustment link 45, that is, the distance between the connecting pin 20 of the horse arm link 17 and the connecting pin 23 of the rotary link 22 can be changed. Here, when the length of the adjustment link 45 is the shortest, when the platform 6 is returned to the predetermined position, the flat platform shielding plate 40 and the platform shielding plate 31 are switched, and the adjustment link 45 When the distance is set to the longest, the tip of the horse arm link 17 falls to the horse arm 4 side. Therefore, the horse arm 4 hits the tip of the horse arm lever 17 in the foremost position with respect to the predetermined position, and the flat base is reached. The shield plate 40 and the horse shield plate 31 can be switched. The angle θ (see FIG. 2) between the center line A of the horse arm 4 at a predetermined position on the platform 6 and the center line B of the horse arm 4 at the most front position is changed in the range of approximately 0 ° to 15 °. be able to.

Therefore, if the platform 6 is used frequently, the adjustment link 45
When the length is adjusted to the maximum length, the position of the horse stand 6 is at the closest position (approximately 15 °), the flat board shield plate 40 and the horse seat shield plate 31 are switched, and the adjustment link 45 is set. Adjust,
If the length is set to the shortest, the position of the horse stand 6 becomes the deepest position (approximately 0 °) and the flat stand shielding plate 40 and the horse stand shielding plate 31 are switched, so that there is an advantage that the flat stand 2 can be fully used. .

In the description of the above embodiment, the positions of the two adjusting plates 41 and 44 are moved to change the length of the adjusting link 45. However, as shown in FIG. 3, the adjusting plates 41 and 44 have opposite screws. Bar screw with 4
8, 49 and one end of each of these bar screws 48, 49 are fitted with long nuts 50 having reverse threads to each other and the adjustment link 45
With this configuration, by rotating the long nut 50, the distance between the connecting pin 20 at the lower end of the horse arm lever 17 and the connecting pin 23 at one end of the rotating link 22 can be adjusted. The same effect as the adjustment link 45 can be obtained.

[Advantages of the Invention] Since the present invention is configured as described above, when the platform is used frequently, the switching position between the flat platform shielding plate and the platform shielding plate is located before the predetermined position of the platform. As a result, since the moving distance of the platform is short, work efficiency is improved. Also,
If the predetermined position (the position of the platform is set to the back), there is an advantage that the entire surface of the flat platform can be used effectively.
