Since the movement of one operating rod that slides in the horizontal direction can be transferred by 90 degrees to the other operating rod that slides in the vertical direction, one operating rod can be connected to the handle and the other operating rod can be locked. For example, multiple actuating members arranged around the window frame of a tiltable casement window or a watertight window can be operated by a handle. Can be operated.

Further, according to the former device, since the rollers provided on the chain roll along the guide member, the chain can be smoothly slid along the guide member, and the pair of operating rods can be smoothly slid.

Furthermore, the latter device uses a steel strip without using a chain or the like, so the structure is simple.

Problems that the invention aims to solve With the former device, it is necessary to provide rollers with a larger diameter than the links at the joints of the links that make up the chain, making the structure of the chain itself complicated and expensive. Put it away.

There is a limit to the size of the guide member due to the installation space such as the width of the window frame, so there is also a limit to the size of the rollers, so the links that make up the chain become smaller and the strength of the chain itself becomes weaker. Therefore, it is not possible to transmit large amounts of force.

With the latter device, when you pull one operating rod to move the other, the steel plate is pulled, so it moves smoothly, but when you push one operating rod and move the other, Since the steel strip is pushed, the steel strip is pressed strongly against the curved groove, so it does not move smoothly.
