Description

[Brief explanation of the drawing]

Figures 1 to 5 show embodiments of the present invention. Figure 1 is a perspective view partially showing a register equipped with a damper opening/closing mechanism of one embodiment, and Figure 2 is the same as Figure 1. FIG. 3 is a side view of FIG. 1, mainly showing the power conversion transmission mechanism of the damper opening/closing mechanism. The explanatory drawings, FIGS. 4 and 5, are similar to FIG. 3 and 6 showing different examples of power conversion and transmission mechanisms, respectively.
This figure is a perspective view similar to FIG. 1, showing a register equipped with a conventional damper opening/closing mechanism. 1... Register, 2... Bezel, 3... Damper, 4... Rotating shaft, 6, 30, 40... Knob for opening operation, 7, 31, 41... Knob for closing operation, 15

Claims (1)

[Claims for Utility Model Registration] (1) At least one damper operating knob mounted to be movable linearly relative to the bezel of the register, and a damper that converts the linear motion of the damper operating knob into rotational motion. A resistor damper opening/closing mechanism characterized by comprising a power conversion transmission mechanism for transmitting power. (2) The damper operation knob is provided with two for opening operation and for closing operation, and is configured such that when one operation is performed, the other is moved in opposite directions via the power conversion transmission mechanism. 1. A damper opening/closing mechanism for a register according to claim 1, characterized in that: (3) The power conversion and transmission mechanism includes a substantially T-shaped lever pivotally supported by the bezel and an arm fixed to the rotation shaft of the damper, and the lever corresponds to the T-shaped horizontal bar. Both ends of the part and the end of the part corresponding to the vertical bar are rotatably connected to the damper operation knob for opening and closing operations and one end of the arm through pins, respectively. A damper opening/closing mechanism for a register according to claim 2 of the utility model registration. (4) When the arm is located on either side of each of the rotation limits corresponding to the fully open position and the fully closed position of the damper, the arm is rotated at each corresponding rotation limit. A damper opening/closing mechanism for a register according to claim 3, characterized in that the damper opening/closing mechanism for a register is provided with a spring biased toward the limit of movement. (5) The power conversion and transmission mechanism includes racks that are provided at each end of the damper operation knob for opening and closing operations and are parallel to each other, and a rack that is pivotally supported on the bezel between these racks. It consists of an intermediate gear member and a sector-shaft gear coaxially fixed to the rotating shaft of the damper, and the intermediate gear member includes a first sector gear and a second sector gear that mesh with each of the racks, and a sector-shaft gear that is coaxially fixed to the rotation shaft of the damper. A damper opening/closing mechanism for a register according to claim 2, characterized in that the mechanism comprises a third sector gear meshing with the gear. (6) The power conversion transmission mechanism includes a shaft gear coaxially fixed to the rotating shaft of the damper, and a shaft gear provided at each end of the damper operation knob for opening and closing operations to sandwich the shaft gear. 3. The damper opening/closing mechanism for a register according to claim 2, characterized in that the mechanism comprises mutually parallel racks extending to a position in which the racks engage with each other and extending in parallel to each other.
