Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rounded interlock switch that provides a stable switching action regardless of the mounting state and position of the switch body and its actuator, and errors due to dimensional tolerances of parts. 4 regarding
It is.

In the conventional device, the actuator and switch are mounted using rigid rounded parts, which has the following disadvantages.

■ Depending on the mounting position of the switch body, the actuator may move out of the operating range 1 and the switch may not be able to be turned on and off completely.

■ Assembly errors occur due to dimensional tolerances of the switch and actuator parts, and the actuator must be adjusted to match the switch body before assembly.

■ When the plunger of the switch is pushed down by the actuator further than its operating limit position, the switch body may be damaged, and the switch installation may cause a metallic odor or deformation of the actuator, requiring re-IUI.

The present invention provides the actuator itself with increased elasticity in order to eliminate and improve the drawbacks of the prior art.

Alternatively, the actuator assembly is constructed by combining a rigid actuator and a ΔN, or the switch body has elasticity attached to the metal fittings that are attached to it, or the switch body and the rigid mounting are connected with one arm between the metal parts. This allows flexibility in mounting the actuator or switch body.

The figure shows an interlitter switch mechanism with a conventional structure. When the Δ-frame 3 is pivoted to the tom frame 6 at the fulcrum 8 and both are locked by the locking mechanisms 18 and 14, the switch body 101) plunger The switch body 1O and the actuator 1 are made of rigid bodies, and each is fixed to a metal A4 plate, while the attachment position of the actuator 1 is adjusted. The position is adjusted with screws and fixed to the Kugo Atsuno or Ichiframe IIKII ■ The main part of the interlock switch mechanism of the present invention is as shown in Figures a and 3, which turns the interlock switch 1G on and off. In order to operate, it is assumed that the heat Δ-7 frame 8 is moved in the direction of the arrow F. #IJ diagram shows 4IIk, and 1m of atcheta IK straight ring is loosely fitted, and the compression spring is 7cm! The installation is housed in gold All,
It is fixed to the upper frame, and the switch body 1
G is composed of a rigid body like Juqin Lan, and I# Tom 7 lem.
It is kept constant. Here, when the frame is moved in the direction of the arrow F, the actuator 1 from S to S is installed, so even if there are manufacturing and assembly errors in each part, the position can be adjusted by SK. Without.

Also, if the actuator 1 is too long, or when the upper 7 frame 8 is locked using the lever 14 and the hook 18, even if it is pushed too far downward, the compression meso ring 9 will move the actuator 1 upwards and close the switch 10. In the embodiment shown in FIG. 3, the actuator l is made of a rigid body like the conventional shoe, and the switch 10 is attached by using a metal plate. It is like a spring. When the upper 7 frame 8 is pressed 6KE1, it becomes the state 4', the plunger device is pushed and the switch lO is engaged, and when the upper 7 frame 8 is released, the switch is installed securely as shown by the number. Restore upwards.

The above explanation is based on the case of a copying machine.

The upper 7 frame 8 is the top surface of the copying machine main body, and when a maintenance-less inner paper jam occurs, the lever 14 is rotated counterclockwise to release the hooks 18 to 14, and the upper 7 frame is moved upward.
Open frame 8. At this time, the switch 10 is turned on. After maintenance or paper removal is complete, lower the frame 3 and interlock the frames with the Leno F-14 and footer l$, and the tip of the actuator l will push down the plunger i, turning on the switch. In this case, if Δ-14 is not engaged with 7 screws and interlock still cannot be achieved, the tip of actuator L is always bitten by the tip of plunger due to the force of spring 1s, and the switch is closed. Safety is ensured by making sure that the brush lever and actuator are moved to the mold position and the switch is activated due to inter-rotation operation like this. However, even if the adjustment is well made, it is normal to constantly need to readjust it during use, but with the interrotter switch mechanism of the present invention, this can be achieved. Even with random assignments, complete intermediation of the switch can occur, and it is highly effective in practical terms.
